Hi all, my caravan system doesn’t seem to want to go from float at 13.75V and 100% SOC to storage mode. I have it connected to shore power, it is only the bare essentials running on 12V to keep my GPS alarm powered. With this circuit on, the breaker lights, and other things I cannot disconnect it is only using 15W. I have 3x 300A Li batteries and would like the voltage & SOC to drop down whilst the van is undercover in my shed.
What do I need to do for storage to kick in. It has been over 24 hours with no big loads on the system.
