Posted March 24, 20232 yr My setup is 2 Axpert/Synerji MKS 5K in parallel, 19kWh battery, total 4kW PV. My settigs: Back to grid bypass 48V, back to battery mode 50V. It's 10h in the morning, sun shining. SOC is around 38%. Due to heavy load (geyser and cooking) the system switched to grid bypass mode. This mode charges the battery from grid with C0.1 and from PV as well, while the loads are connected to the grid. Together they charged with up to C0.19. The battery voltage raised up to 50.4V. It should have switched back to battery mode at 50V but it didn't. I made a try by switching the geyser off. Immediately the system switched back to battery mode. Apparently the Axperts take in account the actual load before switching back to battery mode - intelligent.
