  1. Fixed an issue when inverter in off-grid mode, inverter can't use generator to take load and charge battery.

  2. Optimized the logic of on-grid load taking.

  1. Corrected the sampling of NPE connection.

  2. Logic optimization: When the battery SOC/Voltage is lower than "Start generator charge SOC/VOLT" limit, the dry contact turns on, and only when there is generator input, the inverter enters generator charge mode.

  3. Optimized the control logic for the following scenario: When the PV power is sufficient, but grid sell back is not allowed and there is no load compensation requirement ,once battery is fully charged, BUS over voltage issue happens.

  1. Fixed the logic issue when PV energy is low , the inverter would fail to switch work mode from PV charge to battery discharge

  2. Optimized charge logic of AC coupling input and maximize the use of AC coupling charge

  3. Optimized the logic of charge limit in AC charge mode.
