Title: Resting WBjr
Post by: aaapilot on June 15, 2025, 11:19:05 AM
WBjr in Rosie inverter appears to be stuck reporting 66% SOC. Battery was charged to 100%, as reported by the BMS via Solar Assistant and battery lights, but SOC on MNGP2 never changed past 66%.  Can I 'reset' the unit or ......?  Thanks all

If you are running closed loop with a CAN connection to the battery the Wbjr is ignored and not used.  If running open loop then you can go into the USER/SYSTEM FUNCTIONS and FORCE FLOAT and MNGP2 SOC will read 100%.  Don't do this unless you are sure your SOC is 100% or it will be wrong on the MNGP2

Thank you sir!  I'll give that a shot.
