Abstract: . . .  two types of deep cycle batteries: lead acid, which require the periodic addition of water, and captive electrolyte (or gelcell) batter- ies, which are maintenance free. In addition, PV systems require proper wiring, switches and fuses for safety, controllers to prevent the bat- teries from being overcharged or overly discharged, diodes to allow current to flow in the right direc- tion, and grounding mechanisms to protect against lightning strikes.
