Because of rolling blackouts and personal interests I have decided to build a simple house battery. I want to keep my refrigerator running and have light in some parts of my house. I think 4 12V 200AH deep cycle batteries, a 2000Watt Jupitor inverter a plug in automated charging system will work. I am, however, open to recommendations. I would actually like recommendations about the charging system. The 4 batteries will be connected in parallel to the inverter an the charging system.
