Easysolar 2 GX stuck in sustain since reboot/battery voltage start to drop

Hello all,

I'm facing a strange issue: after a reboot of the Easysolar II GX (network issue), the low battery alarm triggered and the voltage started to go down. The battery status is moving from discharging to Idle continuously.

Before that, everything was working well. The cut-off voltage in ESS seems far lower than the actual battery voltage.1650982313608.png

  • ESS (Keep battery charged) and DVCC are enabled




Firmware versions:

  • SmartSolar Charger MPPT 250/70: v1.59
  • MultiPlus-II 48/3000/35-32 (ACOut2 switchable): v496

I tried to reconfigure everything; also lowering a little the cut-off voltage without better results.

If someone has an idea of what I could try, I would be very happy!
