An off-grid system is completely independent of the utility. Solar energy charges a battery bank, which powers your loads day and night. It's ideal for remote farmhouses, telecom sites, rural clinics and locations with no or very unreliable grid supply.
How it works
- 1Panels charge a battery bank through a charge controller
- 2The off-grid inverter powers your loads from the batteries
- 3Batteries store energy for night-time and cloudy days
- 4An optional DG set can back up during long monsoon spells
Advantages
- Works where there is no grid
- Complete independence from power cuts
- No electricity bills
Good to know
- Higher cost due to batteries
- Battery replacement every 5–10 years
- Must be sized carefully for autonomy
