2. Installation Instructions
2.1 General Installation Notes
Please read the entire installation instructions to get familiar with the installation steps before
installation.
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 sure
ventilation 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 and
destroy 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 the
electric capacity.
Do not place the inverter/charger in a damp, oily, inflammable and explosive or a severe
environment with a large amount of dust accumulation.
Prohibit reverse connection at DC input end otherwise it may damage the equipment or
unpredictable danger will occur.
The utility input and AC output are of high voltage, do not touch the wire connetion.

Determination of installation location: The inverter/charger shall be installed in a place with
sufficient air flow through the dissipation pad of the inverter/charger and a minimum clearance of
150 mm from the upper and lower edges of the inverter/charger to ensure natural thermal
convection. Please see Figure 2-1: Mounting.
WARNING: Risk of explosion!
Never install the inverter/charger with flooded batteries in a sealed enclosure! Do not
install the device in a confined area where battery gas can accumulate.
Step 2：Take down the terminal protective cover
Step 3：Wiring

Connect the system in an order of battery load PV array
GroundUtility in accordance with Figure 2-3: Wiring Diagram. Disconnect the
system in the reverse order.
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 to
Section 2.3 "Wire and Circuit Breaker".
NOTE: If the inverter/charger is to be used in an area with frequent lightning strikes, it is
recommended 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 as
short 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 to
unscrew the screws for connecting their corresponding wires.
②When removing the wirings, first the integrated machine must stop working, and then the screws
shall be unscrewed by using a slotted screwdriver, so as to dismantle their corresponding wires.
Step 4：Install the terminal protective cover
Step 5：Connect accessory
Connect the remote temperature sensor cable (model: RTS300R47K3.81A)
Connect one end of the remote temperature sensor cable to the interface⑥
and place the other end close to the battery.
NOTE：Connect the temperature sensor, the inverter/charger is compensated
according to the ambient temperature.
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 loads
with smaller surge current.
NOTE: In case the inverter/charger is not in normal operation, or LCD or indicator
displays abnormal, refer to Section 5 to clear the fault or contact the after-sale service
personnel of our company.
NOTE：The installation steps and accessory list also refer to the cardboard in the package.

★The voltage parameter are at 25℃, 24V system (twice in 48V system).
◆For the inverter/charger of different power, the current setting range is not the same, see
Technical 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.
3.5 Other function
1) Output voltage & frequency switch
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 as
50Hz.
NOTE：If the output frequency or voltage of the inverter/charger is to be reset, it is
required to turn off the inverter/charger and power on the unit after setting.
