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, 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.
3. Battery: The role of the battery is to ensure the regular power supply of the system load when the solar energy
is insucient and there is no mains power.
4. Home load: Various household and oce loads can be connected, including refrigerators, lamps, televisions,
fans, air conditioners, and other AC loads.
5. Inverter: The energy conversion device of the whole system.
The actual application scenario determines the specic system wiring method.

3. Installation
3.1 Select the mount location
ASF series are designed for INDOOR USE ONLY (IP20) . Please consider the followings before selecting the
location.
• Choose the solid wall to install the inverter.
• Mount the inverter at eye level.
• Adequate heat dissipation space must be provided for the inverter.
• The ambient temperature should be between -10~55℃ (14~131℉) to ensure optimal operation.
• Do not install the inverter where highly ammable materials are near by.
• Do not install the inverter in potential explosive areas.
• Do not install the inverter with lead-acid batteries in a conned space.
• Do not install the inverter in direct sunlight.
• Do not install or use the inverter in a humid environment.

3.2 Mount the inverter
Make 4 mounting holes in the wall with a drill according to the specied dimensions, insert two expansion screws
above and two M5 size screws below for xing the inverter.
3.3 Remove the terminal cover
Using a screwdriver, remove the terminal protection cover.
• 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 aecting the internal air ow rate of the
inverter, which may trigger an over-temperature protection fault (19/20 fault) aecting the use of the
power supply and the service life of the inverter.
