Off-grid solar systems operate completely independent of the utility grid. With battery storage, you have power 24/7 regardless of grid availability.
How Off-Grid Works
- Solar panels generate electricity
- Charge controller manages battery charging
- Batteries store excess energy
- Inverter provides AC power
- Use stored power at night/cloudy days
Benefits
- Complete Independence: No grid dependency
- 24/7 Power: Works during load shedding
- Remote Locations: Ideal where grid isn't available
- No Electricity Bills: Zero IESCO charges
Limitations
- Higher initial cost (batteries)
- Battery replacement every 5-10 years
- Limited by battery capacity
- Requires proper sizing
Components
- Solar panels
- Charge controller (MPPT)
- Battery bank (tubular/lithium)
- Off-grid inverter
