Disconnect Switch on UHG/Solar/AGM system
I am looking at a RT 210P (Chevy chassis) with UHG/one solar panel/two AGM batteries. From a quick review of van, with engine running and inverter on, AC runs as does refrigerator and all lights. But during second test with engine and inverter off, and with LED interior ceiling lights on -- I pressed the battery disconnect switch expecting ceiling lights to go off immediately. They did not go off. a few moments later I took another look in van and the ceiling light was off as would be expected with battery disconnect. But it seemed very odd that the LED lights stayed on for some unknown length of time after the battery disconnect. Batteries have not been maintained and may not be holding a charge. But in any case, why wouldn't LED ceiling lights go out immediately with that battery disconnect switch? Would there be some residual power inside the solar or controller or inverter that takes a while to dissipate? Any thoughts appreciated -- I am just used to our older 190P and everything shuts off immediately with that battery disconnect switch. So the delay of lights going off raises concern that electric system misfired. 2016 model year. Thank you.
