The Best of Both Worlds: Grid Connected + Battery Security

A hybrid system intelligently coordinates three power sources: rooftop solar panels, lithium battery bank, and the KSEB power grid:

1. Direct Solar Usage

During sunny daytime hours, solar power directly runs your air conditioners, refrigerator, and home appliances with priority.

2. Battery Bank Charging

Surplus solar energy is routed to rapidly charge your wall-mounted LiFePO4 battery pack for evening usage and sudden blackouts.

3. Grid Export (Net Metering)

Once the battery reaches 100% capacity, additional energy is exported to KSEB for billing credit so nothing goes to waste.

Comparing On-Grid vs Hybrid Solar

Feature On-Grid Solar Hybrid Solar (Recommended for Blackouts)
Functions during KSEB Power Outages? ❌ Shuts down (anti-islanding safety) ✅ Instant switchover in < 10ms (UPS grade)
Battery Storage No batteries (Grid acts as battery) High-capacity Lithium Iron Phosphate (LiFePO4)
KSEB Net Metering ✅ Yes, exports excess power ✅ Yes, exports after battery is full
PM Surya Ghar Subsidy ✅ Up to ₹78,000 ✅ Up to ₹78,000 on solar generation
Best Suited For Homes with very stable KSEB grid Homes wanting zero power cuts, AC backup, medical equipment

Frequently Asked Questions — Hybrid Solar

What is a hybrid solar system?

A hybrid solar system connects both to your local KSEB grid and to a modern lithium battery bank. It gives you the bill-reducing benefits of net metering plus uninterrupted power during storm blackouts or feeder maintenance.

Can a hybrid solar system run an inverter air conditioner?

Yes. A 5kW hybrid system with a 5kWh to 10kWh lithium battery can effortlessly power a 1.5-ton inverter AC along with refrigerators, water purifiers, lights, fans, and televisions without interruptions.

How long do the lithium batteries last?

We use Tier-1 LiFePO4 (Lithium Iron Phosphate) batteries with a lifespan of 12 to 15 years (over 6,000 charge-discharge cycles) and up to a 10-year manufacturer warranty, far superior to traditional lead-acid tubular batteries.

Can I convert an existing on-grid solar plant to a hybrid system?

Yes. We can retrofit an AC-coupled battery storage system or upgrade your string inverter to a hybrid inverter with a matching lithium battery bank.
