Was originally at 15%. battery went down to 11% and system only came back on on grid despite solar being available.
Problem was not the value.
It appears they finally pushed a new firmware to fix it - it did not work the first time they said it was fixed.
Just had a similar issue. LBCO at 20%, Battery at 19%
PV would not charge the battery and grid was not available.
Had to take it up with Deye and they have done an update.
Waiting to test it out
hello @recre8, which cable did you use with the deye inverter to the Force L1 battery? Have a 5kw Deye with same battery and using the cable in the inverter box to CAN port and we are getting error F58 - BMS comunication fault.
