- Gents,
My second hand mppt has a very annoying issue. Whenever i set my battery setting to user defined one. It changes back after some time- randomly to rotary preset. Here the bulk voltage is much higher than i prefer for my battery pack- thus my BMS gives an error message during charging.
I am wondering the mppt is faulty- any hint here? I tried reset / disconnect reconnect everything - no remedy yet. FW is the latest…
