3.1 General Information
The mounting location is important to the performance and operating life of the controller. The
environment must be dry and protected from water ingress. If required, the controller may be
installed in a ventilated enclosure with sufcient air ow. Never install the TriStar MPPT 150V in
a sealed enclosure. The controller may be mounted in an enclosure with sealed batteries, but
never with vented/ooded batteries. Battery fumes from vented batteries will corrode and destroy
the TriStar MPPT 150V circuits.
Multiple TriStars can be installed in parallel on the same battery bank to achieve higher charging
current. Additional parallel controllers can also be added in the future. Each TriStar MPPT 150V
must have its own solar array.
WARNING: Installation must conform to all requirements of the US National Electrical
Code and the Canadian Electrical Code.
AVERTISSEMENT: Installation doit être conforme à toutes les requirments US
National Electrical Code et Code Canadien d’Electricité.
!
CAUTION: Equipment Damage or Risk of Explosion
Never install the TriStar MPPT 150V in an enclosure with vented/ooded
batteries. Battery fumes are ammable and will corrode and destroy the
TriStar MPPT 150V circuits.
!
CAUTION: Equipment Damage
When installing the TriStar MPPT 150V in an enclosure, ensure sufcient
ventilation. Installation in a sealed enclosure will lead to over-heating and
a decreased product lifetime.
PRUDENCE : Endommagement de l’équipement ou risque
d’explosion
N’installez jamais le TriStar MPPT 150V dans une enceinte avec des
batteries à évent/à électrolyte liquide. Les vapeurs des batteries sont
inammables et corroderont et détruiront les circuits du TriStar MPPT
150V.
PRUDENCE : Endommagement de l’équipement
Assurez une ventilation sufsante en cas d’installation du TriStar MPPT
150V dans une enceinte. L’installation dans une enceinte hermétique
entraîne une surchauffe et une réduction de la durée de vie du produit.
The installation is straight-forward, but it is important each step is done correctly and safely. A
mistake can lead to dangerous voltage and current levels. Be sure to carefully follow each
instruction in this section. Read all instructions rst before beginning installation.
The installation instructions are for installation of a negative grounded system. National Electrical
Code (NEC) requirements are noted on occasion for convenience, however the installer should

Installation3.0
• Read through the entire installation section rst before beginning installation.
• Be very careful when working with batteries. Wear eye protection. Have fresh water available to
wash and clean any contact with battery acid.
• Use insulated tools and avoid placing metal objects near the batteries.
• Explosive battery gases may be present during charging. Be certain there is sufcient ventilation
to release the gases.
• Do not install in locations where water can enter the controller.
• Loose power connections and/or corroded wires may result in resistive connections that melt
wire insulation, burn surrounding materials, or even cause re. Ensure tight connections and use
cable clamps to secure cables and prevent them from swaying in mobile applications.
• Stranded wires to be connected to the terminals should be prepared rst with e.g. clamped
copper heads, tinned-wire ends, etc. to avoid the possibility of one conductor free out of the
connection screw, and possible contact with the metal enclosure.
• Preset charging proles are generally designed for lead acid batteries. Custom settings can be
used for varied charging requirements (see sections 3.2 and 4.2 for details). Note that some
battery types may not be compatible.
• The TriStar MPPT 150V battery connection may be wired to one battery, or a bank of batteries.
The following instructions refer to a singular battery, but it is implied that the battery connection
can be made to either one battery or a group of batteries in a battery bank.
• The TriStar MPPT 150V uses stainless steel fasteners, an anodized aluminum heat sink, and
conformal coating to protect it from harsh conditions. However, for acceptable service life, ex-
treme temperatures and marine environments should be avoided.
• The TriStar MPPT 150V prevents reverse current leakage at night, so a blocking diode is not
required in the system.
• Solar and battery fuses or DC breakers are required in the system. These protection devices are
external to the TriStar MPPT 150V controller, and must be a maximum of 45 amps for the TS-
MPPT-30. 70 amps for the TS-MPPT 45 and 90 amps for the TS-MPPT-60.
• Maximum battery short-circuit current rating must be less than the interrupt current rating of the
battery over-current protection device referenced above.

Step 5 - Remote Temperature Sensor
The included Remote Temperature Sensor (RTS) is recommended for effective temperature com-
pensated charging. Connect the RTS to the 2-position terminal located between the battery (+)
terminal lug and the LED stack (see gure 2-1). The RTS is supplied with 33 ft (10 m) of 22 AWG
(0.34 mm
2
) cable. There is no polarity, so either wire (+ or -) can be connected to either screw
terminal. The RTS cable may be pulled through conduit along with the power wires. Tighten the
connector screws to 5 in-lb (0.56 Nm) of torque. Separate installation instructions are provided
inside the RTS bag.
WARNING: Risk of Fire.
If no Remote Temperature Sensor (RTS) is connected, use the TriStar MPPT 150V
within 3m (10 ft) of the batteries. Internal Temperature Compensation will be used if
the RTS is not connected. Use of the RTS is strongly recommended.
AVERTISSEMENT
: Risque d’incendie.
Si non Capteur de température distant (RTS) est connecté, utilisez le MPPT ProStar
moins de 3m (10 pi) de les batteries. Compensation de la température interne sera
utilisée si la RTS n’est pas connecté. Utilisation de la RTS est fortement recommandé.
!
CAUTION:
The TriStar MPPT 150V will not temperature compensate charging parameters if
the RTS is not used.
!
CAUTION: Equipment Damage
Never place the temperature sensor inside a battery cell. Both the RTS and the
battery will be damaged.
NOTE:
The RTS cable may be shortened if the full length is not needed. Be sure to
reinstall the ferrite choke on the end of the RTS if a length of cable is removed.
This choke ensures compliance with electromagnetic emissions standards.
!
PRUDENCE:
Le TriStar MPPT 150V ne compense pas la température des paramètres de
charges si le RTS n’est pas utilisé.
!
PRUDENCE : Endommagement de l’équipement
Ne placez jamais la sonde de température dans un élément de batterie. Le RTS
et la batterie seraient endommagés.
REMARQUE :
Le câble de RTS peut être raccourci si la totalité de la longueur n’est pas
nécessaire. Assurez-vous de réinstaller la bobine en ferrite sur l’extrémité du
RTS si une longueur de câble est enlevée. Cette bobine assure la conformité
avec les normes d’émissions électromagnétiques.
Step 6 - Grounding and Ground Fault Interruption
WARNING:
This unit is not provided with a GFDI device. This charge controller must
be used with an external GFDI device as required by the Article 690 of the
National Electrical Code for the installation location.
NOTE:
Conductors identied by the colors green or green/yellow should only be used
for earthing conductors.
AVERTISSEMENT :
L’appareil n’est pas fourni avec un dispositif GFDI. Ce contrôleur de
charge doit être utilisé avec un dispositif GFDI externe tel que requis par
l’Article 690 du Code électrique national de la région de l’installation.
Use a copper wire to connect the grounding terminal in the wiring box to earth ground. The
grounding terminal is identied by the ground symbol shown below that is stamped into the wiring
box just below the terminal:
Figure 3-4. Ground Symbol
Do not connect the system negative conductor to this terminal. NEC requires the use of an
external ground fault protection device (GFPD). The TriStar MPPT 150V does not have internal
ground fault protection. The system electrical negative should be bonded through a GFPD to
earth ground at one (and only one) location. The grounding point may be located in the solar
circuit or the battery circuit.
Per NEC 690.45 (A) and NEC Table 250.122, minimum sizes for copper grounding wire are:
• TS-MPPT-30 10 AWG (5 mm
2
)
• TS-MPPT-45 10 AWG (5 mm
2
)
• TS-MPPT-60/M 8 AWG (8 mm
2
)
OR, of the same, or greater, cross-sectional area as the PV wires.
WARNING: Risk of Fire
DO NOT bond system electrical negative to earth ground at the controller.
Per NEC requirements, system negative must be bonded to earth ground
through a GFPD at only one point.
AVERTISSEMENT : Risque d’incendie
NE LIEZ PAS le côté négatif du système à la mise à la terre au niveau du
contrôleur. Selon les exigences du CNE, le côté négatif du système doit
être mis à la terre par un GFPD à un seul point.

Installation
Step 7 - Battery Voltage Sense
The voltage at the battery connection on the TriStar MPPT 150V may differ slightly from the
voltage directly at the battery bank terminals due to connection and cable resistance. The Battery
Voltage Sense connection enables the TriStar MPPT 150V to measure the battery terminal
voltage precisely with small gauge wires that carry very little current, and thus have no voltage
drop. Both battery voltage sense wires are connected to the TriStar at the 2-position terminal
located between the push-button and the positive (+) terminal lug (see gure 2-1).
A battery voltage sense connection is not required to operate your TriStar MPPT 150V controller,
but it is recommended for best performance. If a TriStar meter will be added to the controller, the
battery voltage sense will ensure that the voltage and diagnostic displays are very accurate.
The voltage sense wires should be cut to length as required to connect the battery to the voltage
sense terminal. The wire size can range from 16 to 24 AWG (1.0 to 0.25 mm
2
). A twisted pair
cable is recommended but not required. Use UL rated 300 Volt conductors. The voltage sense
wires may be pulled through conduit with the power conductors.
Fuse the positive (+) voltage sense wire as close to the battery as possible. Size the fuse based on
wire ampacity - a 1A fuse can be used for #24 wire.
Tighten the connector screws to 5 in-lb (0.56 Nm) of torque.
The maximum length allowed for each battery voltage sense wire is 98 ft (30 m).
Be careful to connect the battery positive (+) terminal to the voltage sense positive (+) terminal.
No damage will occur if the polarity is reversed, but the controller cannot read a reversed sense
voltage. Connecting the voltage sense wires to the RTS terminal will cause an alarm.
If a TriStar meter is installed, check the “TriStar Settings” to conrm the Voltage Sense and the
RTS (if installed) are both present and detected by the controller. MSView
TM
PC software can
also be used to conrm the voltage sense is working correctly.
Step 8 - Network Connections
Network connections allow the TriStar MPPT 150V to communicate with other controller or com-
puters. A network can be as simple as one controller and one PC, or as complex as dozens of
controllers monitored via the internet. Review section 5.0 for more information about networking
and the connection(s) required for your system.
WARNING: Shock Hazard
Never route network cables in the same conduit as the power conductors.
WARNING: Shock Hazard
Only use 300 Volt UL rated communication cable.
AVERTISSEMENT : Risque de décharge électrique
N’acheminez jamais les câbles réseau dans le même conduit que les
conducteurs d’alimentation.
AVERTISSEMENT : Risque de décharge électrique

Wire Size
The four large power terminals are sized for 14 - 2 AWG (2.5 - 35 mm
2
) wire. The terminals are
rated for copper and aluminum conductors. Use UL-listed Class B 300 Volt stranded wire only.
Good system design generally requires large conductor wires for the solar and battery con-
nections that limit voltage drop losses to 2% or less. The wire tables in the appendix on pages
51-54 provide wire sizing information for connecting the solar array and battery bank to the
TriStar MPPT 150V with a maximum of 2% voltage drop.
Minimum Wire Size
The NEC requires that the wires carrying the system current never exceed 80% of the
conductor’s current rating. The table below provides the minimum size of copper and aluminum
wire allowed by NEC for all TriStar MPPT 150V models when the current equals the full
nameplate rating (30, 45 or 60 amps). Wire types rated for 75°C and 90°C are included.

35TriStar MPPT Operator’s Manual34 Operation
Operation4.0
The TriStar MPPT 150V operation is fully automatic. After installation is completed, there are few
operator tasks to perform. However, the operator should be familiar with the operation and care
of the TriStar MPPT 150V as described in this section.
4.1 TrakStar
TM
MPPT Technology
The TriStar MPPT 150V utilizes Morningstar’s TrakStar
TM
Maximum Power Point Tracking
(MPPT) technology to extract maximum power from the solar array. The tracking algorithm is fully
automatic and does not require user adjustment. TrakStar
TM
technology tracks the array maxi-
mum power point as it varies with weather conditions, ensuring that maximum power is harvested
from the array throughout the course of the day.
Current Boost
Under most conditions, TrakStar
TM
MPPT technology will “boost” the solar charge current. For
example, a system may have 36 Amps of solar current owing into the TS-MPPT and 44 Amps
of charge current owing out to the battery. The TriStar MPPT 150V does not create current!
Rest assured that the power into the TriStar MPPT 150V is the same as the power out of the
TriStar MPPT 150V. Since power is the product of voltage and current (Volts x Amps), the follow-
ing is true*:
(1) Power Into the TriStar MPPT 150V = Power Out of the TriStar MPPT 150V
(2) Volts In x Amps In = Volts Out x Amps Out
* assuming 100% efficiency. Losses in wiring and conversion exist.
If the solar module’s maximum power voltage (V
mp
) is greater than the battery voltage, it follows
that the battery current must be proportionally greater than the solar input current so that input
and output power are balanced. The greater the difference between the V
mp
and battery voltage,
the greater the current boost. Current boost can be substantial in systems where the solar array
is of a higher nominal voltage than the battery as described in the next section.
High Voltage Strings and Grid-Tie Modules
Another benet of TrakStar
TM
MPPT technology is the ability to charge batteries with solar arrays
of higher nominal voltages. For example, a 12 volt battery bank may be charged with a 12, 24,
36, or 48 volt nominal off-grid solar array. Grid-tie solar modules may also be used as long as
the solar array open circuit voltage (V
oc
) rating will not exceed the TriStar MPPT 150V 150 Volt
maximum input voltage rating at worst-case (coldest) module temperature. The solar module
documentation should provide V
oc
vs. temperature data.
Higher solar input voltage results in lower solar input current for a given input power. High voltage
solar input strings allow for smaller gauge solar wiring. This is especially helpful and economical
for systems with long wiring runs between the controller and the solar array.
An Advantage Over Traditional Controllers
Traditional controllers connect the solar module directly to the battery when recharging. This
requires that the solar module operate in a voltage range that is usually below the module’s
V
mp
. In a 12 Volt system for example, the battery voltage may range from 10 - 15 Vdc, but the
module’s V
mp
is typically around 16 or 17 Volts. Figure 4-1 shows typical current vs. voltage and
power output curves for a nominal 12 Volt off-grid module.

The array V
mp
is the voltage where the product of output current and voltage (Amps x Volts) is
greatest, which falls on the “knee” of the solar module I-V curve as shown on the left in Figure
4-1.
Because traditional controllers do not always operate at the V
mp
of the solar array, energy is
wasted that could otherwise be used to charge the battery and power system loads. The greater
the difference between battery voltage and the V
mp
of the module, the more energy is wasted.
TrakStar
TM
MPPT technology will always operate at the maximum power point
resulting in less
wasted energy compared to traditional controllers.
Conditions That Limit the Effectiveness of MPPT
The V
mp
of a solar module decreases as the temperature of the module increases. In very hot
weather, the V
mp
may be close or even less than battery voltage. In this situation, there will be
very little or no MPPT gain compared to traditional controllers. However, systems with modules
of higher nominal voltage than the battery bank will always have an array V
mp
greater than battery
voltage. Additionally, the savings in wiring due to reduced solar current make MPPT worthwhile
even in hot climates.

charged to the Absorption voltage set-point. The controller will deliver 100% of available solar
power to recharge the battery.
Absorption Stage
When the battery has recharged to the Absorption voltage set-point, constant-voltage regulation
is used to maintain battery voltage at the Absorption set-point. This prevents heating and exces-
sive battery gasing. The battery is allowed to come to full state of charge at the Absorption volt-
age set-point. The green SOC LED will blink once per second during Absorption charging.
The battery must remain in the Absorption charging stage for a cumulative 150 - 180 minutes,
depending on battery type, before transition to the Float stage will occur. However, Absorption
time will be extended by 30 minutes if the battery discharges below 12.5 Volts (25 Volts @24 V,
50 Volts @48 V) the previous night.
The Absorption set-point is temperature compensated if the RTS is connected; otherwise,
voltages set-points are based on the reference of 25ºC.
.
Float Stage
After the battery is fully charged in the Absorption stage, the TriStar MPPT 150V reduces the
battery voltage to the Float voltage set-point. When the battery is fully recharged, there can be
no more chemical reactions and all the charging current is turned into heat and gasing. The oat
stage provides a very low rate of maintenance charging while reducing the heating and gasing of
a fully charged battery. The purpose of oat is to protect the battery from long-term overcharge.
The green SOC LED will blink once every two (2) seconds during Float charging.
Once in Float stage, loads can continue to draw power from the battery. In the event that the
system load(s) exceed the solar charge current, the controller will no longer be able to maintain
the battery at the Float set-point. Should the battery voltage remain below the Float set-point for
a cumulative 60 minute period, the controller will exit Float stage and return to Bulk charging.
The Float set-point is temperature compensated if the RTS is connected; otherwise, voltages
set-points are based on the reference of 25ºC.
Equalize Stage
WARNING: Risk of Explosion
Equalizing vented batteries produces explosive gases. The battery bank must be properly
ventilated.
!
CAUTION: Equipment Damage
Equalization increases the battery voltage to levels that may damage sensitive DC loads. Verify
all system loads are rated for the temperature compensated Equalize voltage before beginning
an Equalization charge.
!
CAUTION: Equipment Damage
Excessive overcharging and gasing too vigorously can damage the battery plates and cause
shedding of active material from the plates. An equalization that is too high or long can be
damaging. Review the requirements for the particular battery being used in your system.
AVERTISSEMENT : Risque d’explosion
Les batteries à évent et compensation produisent des gaz explosifs. Le groupe de batteries doit
être correctement ventilé.
!
PRUDENCE : Endommagement de l’équipement
La compensation augmente la tension des batteries à des niveaux pouvant endommager les
charges sensibles en CC. Vériez que toutes les charges du système sont conçues pour la
tension de compensation par température avant de commencer une charge de compensation.
!
PRUDENCE : Endommagement de l’équipement
Une surcharge excessive et un dégagement gazeux trop vigoureux peuvent endommager les
plaques de batteries et provoquer l’élimination du matériau actif des plaques. Une compensation
trop élevée ou trop longue peut provoquer des dégâts. Examinez les exigences pour la batterie
particulière utilisée dans votre système.

Operation
Certain battery types benet from a periodic boost charge to stir the electrolyte, level the cell
voltages, and complete the chemical reactions. Equalize charging raises the battery voltage
above the standard absorption voltage so that the electrolyte gases. The green SOC LED will
blink rapidly two (2) times per second during equalization charging.
The duration of the equalize charge is determined by the selected battery type. See table 4-1
in this section for more details. The Equalization Time is dened as time spent at the equalize
set-point. If there is insufcient charge current to reach the equalization voltage, the equalization
will terminate after an additional 60 minutes to avoid over gasing or heating the battery. If the
battery requires more time in equalization, an equalize can be requested using the TriStar Meter
or push-button to continue for one or more additional equalization cycles.
The Equalize set-point is temperature compensated if the RTS is connected; otherwise, voltages
set-points are based on the reference of 25ºC.
.
When to Equalize
The ideal frequency of equalizations depends on the battery type (lead-calcium, lead-antimony,
etc.), the depth of discharging, battery age, temperature, and other factors. One very broad
guide is to equalize ooded batteries every 1 to 3 months or every 5 to 10 deep discharges.
Some batteries, such as the L-16 group, will need more frequent equalizations.
The difference between the highest cell and lowest cell in a battery can also indicate the need
for an equalization. Either the specic gravity or the cell voltage can be measured. The battery
manufacturer can recommend the specic gravity or voltage values for your particular battery.
Why Equalize?
Routine equalization cycles are often vital to the performance and life of a battery - particularly
in a solar system. During battery discharge, sulfuric acid is consumed and soft lead sulfate
crystals form on the plates. If the battery remains in a partially discharged condition, the soft
crystals will turn into hard crystals over time. This process, called “lead sulfation,” causes the
crystals to become harder over time and more difcult to convert back to soft active materials.
Sulfation from chronic undercharging of the battery is the leading cause of battery failures in
solar charging systems. In addition to reducing the battery capacity, sulfate build-up is the
most common cause of buckling plates and cracked grids. Deep cycle batteries are particularly
susceptible to lead sulfation.
Normal charging of the battery can convert the sulfate back to the soft active material if the
battery is fully recharged. However, a solar charged battery is seldom completely recharged, so
the soft lead sulfate crystals harden over a period of time. Only a long controlled overcharge, or
equalization, at a higher voltage can reverse the hardening of sulfate crystals.
Preparation for Equalization
First, conrm that all of the system loads are rated for the equalization voltage. Consider that at
0°C (32°F) the equalization voltage will reach 16.75 Volts for 12 Volt L-16 batteries (67.0 Volts for
48 Volt systems) with a temperature sensor installed. Disconnect any loads at risk of damage
due to the high input voltage.
If Hydrocaps are used, be sure to remove them before starting an equalization. Replace the
Hydrocaps with standard battery cell caps. The Hydrocaps can get very hot during an equaliza-
tion. Also, if Hydrocaps are used, the equalization should be set for manual only (DIP switch #7
is Off).
After the equalization is nished, add distilled water to each cell to replace gasing losses. Check
that the battery plates are covered.
Equalize a Sealed Battery?
The Battery Charging Settings table (see table 4-1 in this section) shows two sealed battery set-
tings with an Equalization cycles. These are minimal “boost” cycles to level individual cells. This
is not an equalization, and will not vent gas from sealed batteries that require up to 14.4V charg-
ing (12V battery). Many VRLA batteries, including AGM and gel, have charging requirements up
to 14.4V (12V battery). Depending on the battery manufacturer’s recommendation, the “boost”
cycle for sealed cells can be disabled by setting the equalize setting switch to manual, if required.
Battery Charging Settings
Preset TriStar MPPT 150V battery charging options are shown in tables 4-1 and 4-2 below. All
voltage settings listed are for nominal 12 Volt batteries. Multiply the voltage settings by two (2) for
24 Volt batteries or by four (4) for 48 Volt systems.
NOTE: These settings are general guidelines for use at the operator’s discretion. The
TriStar MPPT 150V can be set or programmed to charge to virtually any specic
requirements, but only the battery manufacturer can recommend optimal settings for
their products.
