EG4_EAAB-1919
2024-03-18
- Changes based on the FAAB-1818
- 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.

2024-02-26
- （Same as fAAB-1818）based on FAAB-1616 and FAAB-1717
- 1.New feature— Parallel Setting Data Sync, synchronize the settings of primary and subordinate inverters.
- 2.New feature— Gen Boost, which enables the PV and battery to work with the generator together when the generator power is insufficient to handle the load.

- 17. Change—The Share Battery function in the US version is enabled by default.
- 18. Problem fixing—Fixing the issue of generator cannot be able to shut down after being started up by Quick Gen start. Generator will be automatically shuts down after 20 minutes of startup.
