1. Safety Instructions
1-1. General Safety Precautions
Warning! Before using the Inverter, read the safety instructions.
Do not expose the inverter to rain, snow, spray or dust. To reduce
the risk of fire hazard, do not cover or obstruct the ventilation
openings and do not install the inverter in a zero-clearance
compartment.
To avoid the risk of fire and electric shock, make sure that the
existing wiring is in good electrical condition, and the wire size is not
undersized.
This equipment contains components which can produce arcs or
sparks. To prevent fire or explosion do not install in compartments
containing batteries or flammable materials or in locations which
require ignition protected equipment. This includes any space
containing gasoline-powered machinery, fuel tanks, or joints, fittings,
or other connection between components of the fuel system.
Depending on the user scenario, the AC output of the inverter may
require user installed breaker or fuse. In AC output hardwire
application, AC socket will not be provided. The inverter incorporates
standard AC short circuit protection.
The following precautions should be taken when working on the
inverter
Step 1 Remove watches, rings, or other metal objects
Step 2 Use tools with insulated handles
Step 3 Wear rubber gloves and boots
Warning! For the terminals on the backplane including AC,
battery, output, signal, please do not change or rework the
terminal wiring unless you are a qualified engineer

1-2. Other Safety Notes
Upon receipt, examine the carton box for damage. Notify the carrier
immediately, before opening, if damage is evident.
Do not operate near water or in excessive humidity.
Do not open or disassemble the inverter, as warranty may be voided.
The DC side connections should be firm and tight.
GroundingReliable grounding should be maintained.
Do not drop a metal tool on the battery. The resulting spark or
short-circuit on the battery or on the other electrical part may cause
an explosion.
Install the inverter in a well-ventilated area. Do not block the front air
vents, or the rear air exhausts of the unit.
WiringAdequate input power must be supplied to the inverter for
proper use; correct wiring sizes must be ensured.
Mount the inverter such that the fan axis is horizontal.
Do not operate the inverter close to combustible gas or open fire.
Do not operate appliances that may feed power back into the
inverter.
TemperatureThe inverter should be operated in an ambient
temperature range of -25 to 40 otherwise the output efficiency
may be affected. Air flow to the inverter must not be blocked.

2. Functional Characteristics Introduction
2-1. System
The SR-1600 PLUS is a highly reliable, modular design DC-AC inverter
system, designed with advanced power electronic and microprocessor
technology offering the following features
Simple setting and scalable system capacity supports up to 32 pcs
(51.2KW)
Seamless switch between AC and DC source
Build-in input and output full isolation
Wide AC input range Adjustable 150~265V (230V system), 75~132V
(120V system)
High efficiency (~95%)
Power factor 0.99
Advanced Protection Features
Input reverse, under-voltage, over voltage protection
Output protectionshort circuit, over load, over temperature,
over voltage protection
Operating mode
AC mode (Default)AC utility power is the main source. DC
power is the secondary source. PFC>0.99. Max efficiency 95%.
When the AC utility abnormal, the switching time is 0 second.
AC Ratio modeDC and AC input at same time. The percentage
of AC and DC load can be assigned to 100%. If AC set 70%, then
remaining 30% is DC.
Note
The AC input power must be higher than 300W after assigning DC and AC ratio.
DC modeDC power is the main source. AC utility is the
secondary source. THD<3%, Max efficiency is 91%. The
switching time between AC and DC power is 0 second.

In case the user needs more than 1 shelf, please use the CN1 and CN2
port to connect multi-shelves. Ensure that user sets the terminal resistor
first (please refer to section 3-2).
Please use RJ-45 cable for connection. To have better performance, we
suggest the cable length is less than 100cm.
