Solarmax 100 Watt Solar Panel + FREE Charger Controller, 300watt Inverter ,3 Bulbs

solarmax solar panel have  high efficiency solar modules are constructed from 36 polycrystalline, (12V modules) or 72 cells (24V modules) cells. The cells are individually tested and matched for optimum performance before being built into the protective module structure. A Tedlar® base is used and ethylene vinyl acetate encapsulant. High transmission the cells from the front and a high strength polymer sheet at the rear. A reinforced aluminium frame completes the laminate structure which is fully sealed against moisture and protected from environmental and mechanical damage.Most common mistake people is mixing of batterys. car batterys are not good in solar storage and have internal resistancefor more information, contact the seller  for guideline

A basic charge controller simply performs the necessary function of ensuring that your batteries cannot be damaged by over-charging, effectively cutting off the current from the PV panels (or reducing it to a pulse) when the battery voltage reaches a certain level.
