Flappy Battery State

I have the following setup

- MultiPlus II 48/5000 70-50

- MPPT 250 | 100 with 12x550W PV panels

- 10.25kWh BSLBATT Powerwall

The battery charges fine, but once it reaches 100% SOC, it keeps switching between, IDLE, DISCHARGING, CHARGING, IDLE, DISCHARGING, CHARGING even while all my loads are run from solar. The SOC goes from 100%, 99%, 100%, 99% etc.

Any idea why this might be happening or how to fix it?

Almost yeah.


See the black graph I posted. The Battery state and vebus out L1 power are constantly flipping between different states onve it reaches 100% SoC. There's no need to use the battery, since there's ample PV to run the loads.
