  8. 8. Off-Grid-Systems for Industrial Applications of off grid system
  9. 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.

  25. 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. 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. 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
