How It Works

Hybrid Solar — Seamless Power in Every Condition

Mode A · Sunny Day

Solar Powers Everything

Solar panels generate electricity → home loads run on solar → excess charges the battery → if battery is full, surplus is exported to KSEB grid for net metering credits.

Mode B · Evening / Overcast

Battery + Grid Backup

When solar output drops, battery steps in first. Grid supplements if battery runs low. You're always powered — the system manages priorities automatically.

Mode C · Power Cut

Instant Battery Switchover

When KSEB grid goes down, the hybrid inverter switches to battery in under 20 milliseconds — imperceptible to appliances. Your home continues without interruption.

Comparison

Hybrid vs On-Grid — Which Should You Choose?

Hybrid Solar — Recommended for Power Cut Areas

Backup power during outages — home continues seamlessly
Battery stores solar for evening and night use
KSEB net metering credits still earned
Can operate independently from grid when needed
Protects appliances from voltage surges during cuts
Best for: 2+ power cuts per week areas

On-Grid Solar — Best for Reliable Grid Areas

Lowest upfront cost — no battery expense
Full PM Surya Ghar ₹78,000 subsidy eligible
KSEB net metering credits earned
System shuts off when KSEB grid goes down
No backup during power cuts
Best for: Areas with <1 cut per week

FGE Solar recommends hybrid for areas with more than 2–3 power cuts per week. Our engineers will assess your specific situation and recommend the right system.

FAQ

Hybrid Solar FAQs

A hybrid solar system combines on-grid and off-grid capabilities. It connects to the KSEB grid AND has a battery bank for backup. During normal operation, solar powers your home with grid as backup. During power cuts, the battery takes over seamlessly — the switchover happens in under 20 milliseconds, undetectable to appliances.
It depends on battery capacity and your load. A 10kWh battery backing up essential loads (lights, fans, router, fridge) typically lasts 8–12 hours. FGE Solar sizes battery systems based on your critical load requirements and how many hours of backup you need.
If you experience frequent power cuts — which is common in many Kerala districts — hybrid solar pays for the extra cost through convenience, appliance protection from surges, and eliminating the need for a separate UPS/inverter. For areas with reliable grid power (less than one cut per week), on-grid solar is more economical.
Yes, in many cases. Whether an upgrade is possible depends on your existing inverter model and brand. Some inverters can be retrofitted with battery storage modules. FGE Solar can assess your current system and advise on the most cost-effective upgrade path — sometimes a new hybrid inverter is the best option.
