2.3、System connection diagram
The diagram below shows the system application scenario of this product. A complete system consists
of the following components:
•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.
•Utility grid or generator: connected to the AC input, it can supply the load and charge the battery at the
same time. The system can also operate generally without the mains or generator when the battery and
the PV module power the load.
•Battery: The role of the battery is to ensure the regular power supply of the system load when the solar
energy is insufficient and there is no mains power。
•Home load: Various household and office loads can be connected, including refrigerators, lamps,
televisions, fans, air conditioners, and other AC loads.
•Inverter: The energy conversion device of the whole system.
The actual application scenario determines the specific system wiring method.

3.2、Mount the inverter
Make 4 mounting holes in the wall with an electric drill according to the specified dimensions, insert 2
expansion screws above and fix the inverter with 2 M5 screws below.
3.3、Remove the terminal cover & anti insect net
Using a screwdriver, remove the terminal protection cover and anti insect net.
⚫When using the device in areas with poor air quality, the dust screen is easily blocked by
airborne particles. Please dismantle and clean the dust screen regularly 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.
