I bought the Renology 200 watt solar panel kit, I am confused on which batty to use a 12 volt or two 6 volts. Mostly I need electric for a cpap machine a fan and maybe a small tv, any suggestions and tips would be greatly appreciated
Almost There said:A pair of Trojan T105s or T105REs would be perfectly suited for the 200 watt solar kit you have...they'd provide 225 amp hours which I would expect should be enough for the cpap machine. I've not used one but if I remember correctly the machine draws enough that I wouldn't want to rely on anything smaller.
If you can swing the higher price of the T105REs they have much better life expectancy and warranty.
IMO, one should always have at least a second way of charging the battery bank. Most people don't drive enough each day (5 hours or more) to fully recharge their battery bank, unless they are on a road trip. Either planning on plugging in to shore power with a well matched battery charger or having a generator on hand is all part and parcel of dealing with off grid electrical needs. It's a mindful process radically unlike our many years of taking electricity for granted!
