I have slowly over the years learned a lot about solar battery setups through others and the good and bad of their plans. (So many bad setups) I know a lady now who once spent thousands on her setup.I have not seen it. She told me it will not do what she thought it would do.She actually thought it should run a washing machine.It is now used mainly for a small TV set.It isn't reliable for this even. She also has a 400-watt windgen setup. Her problem now is replacing batteries that are dying and using RV batteries that just are not up to the task. Sealed batteries seem to die. Especially expensive ones. I like non sealed batteries and keep a schedule for inspections and maintenance.Make sure they are not brought down too much. My plan is to use a 130-watt panel to charge up small batteries. AA and AAA. Communication devices. Through a large battery with a charge controller. I learned a lot from using this setup to run a chicken coop with an electric fence.It saved my chickens a few times.Very stunning when I got zapped myself! For rooms, I also have smaller systems with batteries hooked up to LED lights meant for cars. I try to keep it simple. And have extra setups to back everything up. If I had the cash I would get a large battery setup like they have for electric forklifts. But I do what I can. From what I have seen people expect too much from their setup and are disappointed. consider what it would be like if all your battery's let you down. It seems to be the trend for solar setups.
