I have the following system all connected to a Cerbo GX
Two SmartSolar Charger MPPT 100/20 48V
MultiPlus-II 48/3000/35-32 (ACOut2 switchable)
One Pylontech US2000C
The system has been working for two years. Recently, I upgraded Cerbo GX to v3.66, Multiplus II to v558, and MPPT to v1.68. Now, I got a low battery alarm, even though the battery is full. And, the MPPT’s don’t generate any power. Any clue what could be wrong?
Inspired by the following disucssion, I changed ESS mode from Optimised (with BatteryLife) to Keep batteries charged. The two MTTP’s shortly ramped up to generate power. Then they were throttled. One is shutdown complete, the other only generates 40W.
After updating to V558 all mine settings are gone and ESS assistant (VEConfig) was not valid any more.
Think your settings are also changed and do produce low battery error
