Hello again, checking if anyone has heard of or had similar experiences; example, had problems with our living room slide (hwh hyd) would not move at all - reset 12v system and slide worked great, 2nd example, batteries charged 12.8+ (equip: Samlex Solar - 100w , 30amp charge controller, ssw-r1 12b remote control, intell power 9200 power converter,and samlex power 1000 inverter) football on the TV and Samlex remote control shows low battery and shuts power to TV off. Turned back on after a couple of minutes and power shut down again, here is the odd part, reset the 12V system and everything again work normal, TV was fine and remote control showed 12.8V. thanks for your feed back!
