Battery Energy Storage Systems (BESS)

For short outages (up to 2–4 hours), absolutely. Batteries respond in milliseconds versus 8–12 seconds for a DG. There's no diesel cost, no exhaust emissions, no noise, and no maintenance headaches. For longer outages, a hybrid setup (BESS + DG) works well — the battery handles immediate transfer and the DG takes over for extended periods. Many factories are replacing their DG sets with BESS + solar for both economic and compliance reasons.

LFP battery systems currently cost ₹1.2 to ₹1.8 crore per MWh (installed) depending on the power rating, container configuration, and integration complexity. A typical 500 kWh system for an SME factory would run around ₹60–90 lakhs. The payback depends on your peak-to-off-peak tariff difference — in states with high ToD differentials like Gujarat and Maharashtra, payback is 4–6 years.

Yes, and it's one of the best use cases. Your solar system generates peak power during midday when you might not need all of it. The BESS stores the surplus and releases it during evening peak hours or night shifts. This combination can push your grid independence to 80–90% for many industrial load profiles.

LFP chemistry delivers 6,000+ deep discharge cycles at 80% depth of discharge. In a typical peak-shaving application with one cycle per day, that translates to about 15–18 years of useful life. Even after 6,000 cycles, the battery still retains about 70–80% of its original capacity. Compare that to lead-acid which gives you 1,000–1,500 cycles at best.

LFP is the safest lithium battery chemistry available. Unlike NMC (Nickel Manganese Cobalt) cells that can experience thermal runaway at elevated temperatures, LFP cells have a much higher thermal stability threshold. Our containers include multiple safety layers — cell-level fuses, rack-level disconnects, BMS with temperature monitoring, smoke detectors, and aerosol fire suppression systems tested to UL 9540A standards.
