Hybrid & Off-Grid Solar Systems with Battery Backup
Power cuts solved with lithium storage and intelligent hybrid inverters

When net-metering alone is not enough
An ordinary on-grid system shuts down the moment grid supply fails — a safety requirement called anti-islanding. If your area has long or frequent outages, a hybrid system gives you the same solar savings plus genuine backup.
How we size a hybrid system
- List your essential loads and how long you need them (e.g. 6 lights, 4 fans, 1 fridge for 4 hours).
- Convert to kWh of battery capacity, then apply depth-of-discharge and efficiency margins.
- Size the solar array to serve daily consumption plus battery recharge within the solar window.
- Select the hybrid inverter with grid-export capability so you still earn net-metering credit.
Battery choices
LiFePO4 lithium: 6,000+ cycles, compact, maintenance free — recommended where budget allows.
Tubular lead-acid: lower upfront cost, needs water top-ups, 1,200–1,500 cycles.
For remote farms and construction sites, off-grid systems with generator synchronisation are the most cost-effective way to get reliable power without waiting for a connection.

Hybrid & Off-Grid Solar Systems with Battery Backup FAQs
How much subsidy do I get on rooftop solar in Maharashtra?
Under PM Surya Ghar: Muft Bijli Yojana, residential consumers get ₹30,000 per kW up to 2 kW and ₹78,000 in total for 3 kW and above. The amount is credited directly to your bank account after installation and net-metering are completed.
How many units does a 3 kW solar system generate per month?
In Maharashtra a well-designed 3 kW rooftop system generates roughly 340–380 units per month across the year, higher in March–April and lower during the monsoon. That typically offsets most or all of a 2–3 BHK household’s consumption.
How long does installation take after I confirm?
Structural work and installation usually take 7–14 days for residential systems once material reaches your site. Net-metering approval and meter installation by MSEDCL typically add 3–6 weeks depending on the circle office workload.
Do you help with the PM Surya Ghar subsidy application?
Yes. We register your application on the national portal with your consumer number, follow up the feasibility approval with your DISCOM, submit the commissioning certificate and track the subsidy until it is credited to your bank account.
What is the difference between on-grid and hybrid solar?
An on-grid system exports surplus power and shuts down during a grid outage for safety. A hybrid system adds a battery bank so you keep running essential loads during outages while still enjoying net-metering credit for exported units.
Can I get a solar loan or EMI?
Yes. We prepare the project report and documentation for solar loans from SBI, Bank of Baroda, HDFC and NBFCs. A 3 kW system works out to roughly ₹2,450 per month over 60 months, which is usually less than the bill it replaces.
