- 9. 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.

- 20. Off Grid Solar Power System Off grid system design
- 21. Off grid system components • PV Array • Solar Charge Controller • Battery Bank • Inverter • Load (AC OR DC) • Generator(Optional) • Required electrical safety gear (i.e. fuses, breakers, disconnects)
- 22. PV Array It is commination Of PV Modules In series and Parallel Module in series : String Strings in parallel : PV Array Off grid system components
- 23. PV Array Off grid system components
- 24. PV Array- Real view Off grid system components
- 25. Solar Charge Controller Charge regulators or just battery regulators • The main function is to protect the batteries • Block Reverse Current Types Of controller • PWM Charge controller • MPPT Charge controller Off grid system components
- 26. Battery Bank • Storing Energy in daytime. • Battery bank is essentially a group of batteries wired together. • Lead Acid type batteries are most common in Solar PV system Off grid system components
- 27. 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 Off grid system components
