[QUOTE="chrisc, post: 1156353, member: 746"] Did you reset the BMS? I have 2 SHOTO 5100wH batteries, one is 14 months old, the other 8 months. I was instructed to make the new battery 1 and the older battery 2. This is done with DIP switches on the battery and a LAN cable attached to the RS485A ports All well and good In June a transformer blew at a local sub station and we were without power for 53 hours. Plus it was cloudy and overcast for 2 days. Being careful not to exceed 135 watts load, the batteries still discharged to 25% and the inverter shut off When the power restored, battery no 1 would not charge beyond 50%. I found out how to reset the BMS and on the recommendation of the supplier, swapped 1 and 2 around. In 6 hours both batteries are back at 100% state of charge [/QUOTE]
