2. Installation Instructions
2.1 General Installation Notes
• Please read the entire installation instructions to get familiar with the
installation steps beforeinstallation.
• Be very careful when installing the batteries, especially flooded lead-acid battery.
Please wear eye protection, and have fresh water available to wash and clean if any
contact with battery acid.
• Keep the battery away from any metal objects, which may cause short circuit of the
battery.
• Explosive acid battery gases may come out from the battery during charging, so
make sureventilation condition is good.
• Ventilation is highly recommended if mounted in an enclosure. Never install the
inverter/charger in a sealed enclosure with flooded batteries! Battery fumes from
vented batteries will corrode anddestroy the inverter/charger circuits.
• Lead-acid battery is only recommended, other kinds please refer to the battery
manufacturer.
• Loose connections and corroded wires may result in high heat that can melt wire
insulation, burn surrounding materials, or even cause fire. Ensure tight connections
and use cable clamps to secure cables and prevent them from swaying in motion.
• Select the system cables according to 5A/mm2or less current density in accordance
with Article 690 of the National Electrical Code, NFPA 70.
• For outdoor installation, keep out of the direct sunshine and rain infiltration.
• High voltage still exists inside the inverter/charger after switching off the power
switch, do not turn on or touch the internal units, conduct the associated
operation only after discharging theelectric capacity.
• Do not place the inverter/charger in a damp, oily, inflammable and explosive
or a severeenvironment with a large amount of dust accumulation.
• Prohibit reverse connection at DC input end otherwise it may damage the
equipment orunpredictable danger will occur.
• The utility input and AC output are of high voltage, do not touch the wire connetion.

Warning: Danger, High-voltage! Utility input, AC output and PV array will
produce dangerous voltage, make sure to disconnect the circuit breaker/
fuse before wiring.
Warning: Do not turn on the circuit breaker/ fuse when wiring, and at the
same time,ensure that the wiring of “+”, “-” are correctly connected.
Warning: A circuit breaker must be installed at the battery end, for
selection, refer toSection 2.3 "Wire and Circuit Breaker".
NOTE: If the inverter/charger is to be used in an area with frequent lightning
strikes, it isrecommended to install an external surge arrester at the PV input.
➢Grounding
Grounding connection must be made when utility is connected to the
inverter/charger. The inverter/charger has dedicated grounding terminal as shown in
Fig. 2-3, the grounding must be reliable, the grounding wire have to stay consistent
with Recommended wire for AC output, the grounding point shall be as close as
possible to the inverter/charger, the grounding wire shall be asshort as possible.
➢AC output, Ground and PV wiring terminal use way:
①When wiring, do not close the circuit breaker, and it is necessary to use a slotted
screwdriver tounscrew the screws for connecting their corresponding wires.
②When removing the wirings, first the integrated machine must stop working, and
then the screwsshall be unscrewed by using a slotted screwdriver, so as to dismantle
their corresponding wires.
Step 4：Install the terminal protective coverStep
Step 5：Connect accessory
 Connect the remote temperature sensor cable (model: RTS300R47K3.81A)
Connect one end of the remote temperature sensor cable to the
interface⑥and place the other end close to the battery.
NOTE：Connect the temperature sensor, the inverter/charger is compensated
according to the ambient temperature.
 Connect the remote temperature sensor cable (model: RTS300R47K3.81A)
 Connect the accessories, monitor the system status and set the parameters via
PCsoftware or APP software.

Step 6：Recheck if the wire connection is correct
Step 7：Power on the inverter/charger:
①Turn on the circuit breaker at the battery end.
②Switch on the switch then the inverter indicator is on.
③Turn on the breaker of PV array and Utility.
④Turn on the AC load when the AC output is normal.
NOTE: In case the power is supplied to the different AC loads, it is suggested to turn
on the loads with larger surge current, till the load working well, then turn on the
loadswith smaller surge current.

same, seeTechnical Parameters for details.
NOTE：
15/16：Stop/restore auxiliary module charging voltage. Only when the charging mode is Solar
priority or Utility priority will the auxiliary module charging voltage be effective.
20：Power saving mode
When the switch is on “Saving” side, the inverter will enter into the Saving Mode. It will
shut off the output if the loads value is less the 70W. Then restart and detect the power
of the load again after 10s.If the load is more than 70W, the inverter will turn on the
output. Otherwise it will shut off output.It cycles like this. So please don’t use the saving
mode if the load is smaller than 70W.
21：Clear the faults
In occurrence of short circuit or overload caused to AC output, the fault can be cleared out.

 When Switch 1 is in "ON", the output voltage is selected as 230VAC, and on the contrary as
220VAC;
 When Switch 2 is in "ON", the output frequency is selected as 60Hz, and on the contrary as50Hz.
NOTE：If the output frequency or voltage of the inverter/charger is to be reset, it
isrequired to turn off the inverter/charger and power on the unit after setting.
2 ） Relay interface
Working principle: When the battery voltage reaches the Low Voltage Disconnect
Voltage（LVD）,the coil of relay is energized, and the switch is turned on. The dry
contact can drive resistive loads 125VAC /1A, 30VDC/1A.
3 ） Remote interface
Remote interface input voltage (3.3~12V)
(1) The input voltage Vi is within 2.5~ 10s, the AC output state is reversed (when the
AC is formerlyin output state, now it is in no-output state ; when the AC is formerly in
no-output state, now it is in output state;)
(2) The input voltage Vi is greater than 10s, the AC is in output state all the time till the
input voltageVi disappears.
NOTE: If it is to change the range of input voltage, it can be realized by
changing theresistance value of R.
