It sounds like you actually have 4 12 V lead acid battery modules in series; these may be at end of life or not properly charged. 17 hours ago, Audrey Jansen said: 5kw rct inverter with 10 360 w solar panels We need to know what model of RCT inverter, and how the panels are connected. It could be that the inverter is shutting down solar most of the time, so that the battery ends up undercharged. But since the system works well during the day, my suspicion is on the battery.
