Multiplus 2 Overloads and Randoms Shuts Down...Grid connection problems

All those experiencing the same problems outlined abive..i encourage you to check out firmware version 478 for the MP2. Been a week now and have numerous loadshedding sessions....the system has been very stable.


I struggled with these tripping nuesances and want to let everybody know that the MP2 is doing in well especially with our weak grid here in Zimbabwe

Are you using a bms controllee battery? Are yo getting any errors causing the battery to be opening and closing its contactors?

Have you tried to UP the low voltage Ac shut down? I would try to set it at plus 200Ac and 205 reconnection.

Also what grid code are you using?
