| Microtek | ₹21,000 | ₹34,000 | ₹51,000 | ₹98,000 |
| Fronius | ₹45,000 | ₹75,000 | ₹1,20,000 | ₹2,00,000 |
Best for Urban Areas
Urban homes with reliable grid connections benefit most. You eliminate electricity bills and earn money from excess generation. Payback period ranges 3-5 years depending on your location’s solar irradiance.
Off-Grid Solar Inverters
Off-grid inverters work independently without grid connection. They require battery backup to store energy for nighttime use. These systems provide complete energy independence but can’t sell excess power to utilities.
Battery Backup Solutions
Battery costs add ₹15,000-₹25,000 per kWh of storage. A typical 5kW system needs 10-15 kWh battery backup, adding ₹1,50,000-₹3,75,000 to total costs.
Lithium batteries cost double but last 10 years compared to 4-5 years for lead-acid batteries. Your choice affects long-term costs significantly.
Price Range: ₹15,000 – ₹1,50,000
| Capacity | PWM Price | MPPT Price | Battery Cost |
| 1kW | ₹15,000 | ₹22,000 | ₹30,000 |
| 3kW | ₹25,000 | ₹40,000 | ₹90,000 |
| 5kW | ₹40,000 | ₹65,000 | ₹1,50,000 |
| 10kW | ₹80,000 | ₹1,20,000 | ₹3,00,000 |
Ideal for Rural Areas
Rural locations with unreliable grid power benefit most. You get 24/7 electricity independence regardless of grid conditions. Higher upfront costs offset by eliminating generator fuel expenses.
Hybrid Solar Inverters
Hybrid inverters combine on-grid and off-grid functionality. They can store energy in batteries while remaining connected to the grid. This setup provides backup power during outages and grid interaction during normal times.
