I have a pair of SK48v100 batteries, in parallel, that I purchased in June. So far, they have been working fine. Today when I realized I didn't have any internet I thought my inverter had shut down. When I checked on the system, everything was powered off, including the batteries. I reset them w/ the reset button and they came back online. I checked the voltage, the BMS screen said 49.9v (3.1v per cell) and I verified it w/ my meter. After a couple of minutes, they shut down again. The BMS screen does not say it shuts down for low voltage...so I can't figure out why they are shutting down. The manual says they auto shut down at 48v...I know they have been getting low due to the winter months, but they are not down to 48v.
Any ideas why they are shutting down?
I did notice that the BMS says they are at 35% charge and the victron smart shunt says 13%...I think one of the 2 has 'drift' due to the erratic (low) charging I have been getting during these poor sun months.
