2.3 System connection diagram
The diagram below shows the system application scenario of this product. A complete system consists
of the following components:
1. PV modules：converts light energy into DC energy, which can be used to charge the battery via an
inverter or directly inverted into AC power to supply the load.
2. Utility grid or generator：connected to the AC input, either of the connected utility and generator can
charge the battery while supplying the load. When the batteries and photovoltaic modules supply the
load, the system can operate without the utility or generator.
3. Battery：The role of the battery is to ensure the normal power supply of the system loads in case of
insufficient photovoltaic and no utility power.
4. Home load：connects to a variety of home and office loads including refrigerators, lamps, TVs, fans,
air conditioners and other AC loads.
5. Inverter：it is the energy conversion device of the whole system.
The actual application scenario determines the specific system cabling.

3.2 Mount the inverter
Drill 4 mounting holes in the wall with an electric drill according to the specified dimensions, insert 2
expansion screws above and 2 M5 screws below to fix the inverter.
3.3 Remove terminal protection cover and dust screen
Using a screwdriver, remove the terminal protection cover and dust screen.
When using the device in areas with poor air quality, the dust screen is easily blocked by air particles.
Please disassemble and clean the dust screen periodically to avoid affecting the internal air flow rate
of the inverter, which may trigger an over-temperature protection fault (19/20 fault) affecting the use
of the power supply and the service life of the inverter.

•PV input, AC input, AC output
1. Use a stripper to remove the 6~8mm insulation of the
cable.
2. Fixing a ferrule at the end of the cable (ferrule needs to
be prepared by the user).
•Battery
1. Use a stripper to remove the 6~8mm insulation of the
cable.
2. Fixing cable lugs that supply with the box at the end
of the cable.
The wire diameter is for reference only. If the distance between the PV array and the inverter or
between the inverter and the battery is long, using a thicker wire will reduce the voltage drop and
improve the performance of the system.
4.3 AC input & output connection
Connect the live, neutral and ground cables in the position and order of the cables as shown in the
diagram below.
○
! NOTICE 
•Before connecting the AC input and output, the circuit breaker must be disconnected to
avoid the risk of electric shock and must not be operated with electricity.
•Please check that the cable used is sufficient for the requirements, too thin, poor quality
cables are a serious safety hazard.

UTI default
Utility Priority. Utility power is given priority to the
loads, the battery inverts to provide power to the
load only when utility power is unavailable.
SBU
Prioritises the use of PV to power the load and
switches back to the mains to power the load only
when the battery voltage is lower than the set
value in parameter item [4] (when connected to
the BMS, according to item [61]). When the battery
voltage is higher than the value set in parameter
[5] (when connected to the BMS, according to item
[62]), it switches back to the PV from the mains to
supply the load.
SOL
PV priority. Switching to mains to power the load
when PV is not effective or when the battery is
below the setting of parameter item [4].

charging.
Note: The PV and mains can only be charged at
the same time when the mains bypass output is
loaded. When the inverter is operating, only PV
charging can be initiated, not utility charging.
CUB
Utility is the first priority in charging, PV charging
the battery only when utility is not available.
CSO
PV is the first priority in charging, utility charging
the battery only when solar power is not sufficient.
OSO
PV charging only, no utility charging.
