  1. I have 2x5kw Solis inverters connected to 6.6kw solar panels each and producing 70+kW on a good August day se Qld Australia 1 month in, faultless 10 year warranty.

    And I have friends tell me they had more expensive brands fail 3 weeks in

  2. Please review all models of Solis inverters particularly the 5kW version. This is a regularly offered inverter in Australia for cheap systems (don’t mean it is bad, just cheap).

  3. Can anyone help me here, I have installed Solis 5 kva at my residence, at screen it is showing that it is generating power, but it is still consuming electricity from the govt. resource

  4. What does
    “MPPT only shadow management.”
    That there is no real shadow management and if there is shadow it may not find the real most power point?
