1. Grid tie....this is where you tie the panels directly into the electrical system...it essentially supplements the power in your house and has no batteries.
2. Hybrid: Combination of Grid ties and Battery Bank used in conjunction with and inverter and a relay. When the power goes out the bank kicks in.
3. Stand alone....panels to charge controller to batteries....better know as a Solar Generator.
If all you want is simple charging I would recommend a small battery bank of 5 12AH 12V SLA batteries. This would support the most basic of what you are looking for.
