Off-Grid-Systems – Applications for home lighting
1. Solar lamps with community charging It contains a CFL / LED lamp and a
rechargeable battery. These lamps are charged at charging stations run by rural entrepreneurs.
2. Solar lamps with individual PV panel for charging It contains CFL / LED lamp, rechargeable
battery and an individual solar panel. These solar lamps recharge during the day.

Off-Grid-Systems – Applications for home lighting
Solar home lighting systems: This consists of a single solar panel /
module mounted on the roof, connected via a voltage regulator to a battery
Solar micro grid systems: Solar micro grid systems consist of a set of
solar photovoltaic panels for electricity generation, a battery pack for charging and storage of electricity for night or anytime when sun is not there and small scale version of the centralized electricity system, established by the community being served.

Off grid Inverter (Stand alone Inverter)• Draws its DC energy from batteries charged by Charge
Controller.• Do not interface in any way with the utility grid.• Many stand-alone inverters also incorporate integral
battery chargers to replenish the battery from an AC source.
Most inverters are not designed for use in off-grid PV
systems
