  1. Axpert 5KV+, Error 51, overload/surge

    Christo replied to Chris Knipe's topic in Inverters
    I also had an error 51 on a VM model, the power supply is the same as on the MKS models. Changed C78, C79, C132 and U20. Error 51 did not occur again. What I also saw was that the output voltage fluctuated between 229V and 231V, this only happens when the battery voltage is below 51.5V. If the battery is 51.5V or above the output voltage is constant 230V.

  2. Axpert Inverter switching to battery power at midday.
