Solar battery backup systems in Kerala

Monsoon outages, evening peak loads, or off-grid plots — when net metering alone isn't enough, a lithium battery layered onto your solar system keeps the lights on. We design Tier-1 LFP storage sized to your actual load.

When you actually need a battery

• Long monsoon power cuts (4+ hrs typical in some Kerala panchayats) • Evening-heavy loads — solar generates by day, you consume after sunset • Critical loads — work-from-home, medical equipment, food storage • Off-grid sites — farmhouses, hill plots, construction sites • Future EV charging buffer

System sizing rule of thumb

Essentials only (lights, fans, fridge, Wi-Fi, TV): 5 kWh Essentials + 1 AC for 4 hrs: 10 kWh Essentials + 2 ACs + work setup: 15–20 kWh We meter your home for 7 days before sizing — no guesswork.

What's included in a Mastride battery install

• Tier-1 LFP cells (BYD / Pylontech / Luminous LiFe class) • Integrated BMS with cell-level monitoring • Hybrid inverter compatible with KSEB net metering • Indoor cabinet with thermal management • 10-year cell warranty + 5-year free service visits • App-based monitoring of state-of-charge & backup runtime

Frequently asked questions

+Do I need a battery for solar in Kerala?

Not for bill reduction — KSEB net metering already 'banks' your excess generation. Batteries are for power-cut backup, evening loads, or off-grid sites.

+Lithium or lead-acid for solar?

Lithium (LFP) is now standard — 6,000+ cycles, 10-year life, 95% round-trip efficiency. Lead-acid is cheaper upfront but costs more per kWh over its life.

+How much battery for a typical Kerala home?

A 5 kWh LFP battery covers 4–6 hours of essentials (lights, fans, fridge, Wi-Fi, TV) for a 3-BHK. Add 5 kWh per AC you want to keep running.

+Battery cost in Kerala 2026?

LFP batteries land at ₹28,000–₹38,000 per kWh installed including BMS, cabling and inverter integration. Mastride uses Tier-1 cells with 10-year warranty.
