  • Page 4: Safety

    Danger. Risk of electric shock! Danger to life due to high voltage. There is residual voltage in the inverter which needs 5 min to discharge. Wait 5 min before you open the upper lid or the DC lid. Read the manual. Product should not be disposed as household waste.

  • Page 5: Pe Connection And Leakage Current

    Any time the inverter has been disconnected from the public network, please be extremely cautious as some components can retain charge sufficient to create a shock hazard. Prior to touching any part of the inverter please ensure surfaces and equipment are under touch safe temperatures and voltage potentials before proceeding.

    in rural areas where electricity is usually provided by long overhead lines. Surges may impact on both the PV array conduction and the AC cables leading to the building. Specialists in lightning protection should be consulted during the end use application. Using appropriate external lightning protection, the effect of a direct lightning strike into a building can be mitigated in a controlled way, and the lightning current can be discharged into the ground.

    • Work modes: Work modes Description Priority: load>battery>grid Self-use The energy produced by the PV system is used to optimize self-consumption. (with PV Power) The excess energy is used to charge the batteries, then exported to gird. When no PV supplied, battery will discharge for local loads firstly, and grid will Self-use supply power when the battery capacity is not enough.
