The sun does not send a bill. But storing its energy requires the right battery. The Uttam Electric 12V 100Ah Solar Inverter Battery is the foundation of residential solar storage in India. It captures what the panels generate during the day and delivers it when the grid fails or the sun goes down. Simple. Essential. Reliable.

Built with 3.2V 150Ah LFP prismatic cells, this pack is deliberately over-specified at the cell level. The cells are rated higher than the pack capacity, which means they never operate at full stress. This design choice extends cycle life dramatically. Where lead-acid batteries fade after 300 to 500 cycles, this LFP pack delivers thousands. The economics shift from replacement costs to long-term savings.

At 18 kg and 250 x 180 x 235 mm, the battery is compact enough to sit beside any standard home inverter. No dedicated battery room required. No ventilation concerns. LFP does not emit gases during charging, unlike lead-acid alternatives. Your living space stays clean and safe.

Over-voltage protection guards against irregular grid charging and solar charge controller faults. The smart BMS monitors cell health continuously, providing data that helps installers diagnose issues before they become failures. IP65/67 dual rating means this battery handles humid coastal environments and dusty inland conditions equally well.

Charging takes 6 to 10 hours depending on solar availability and charger amperage. The 60-month warranty with replacement and repair coverage reflects the confidence Uttam Electric places in this product. Five years of assured performance. Manufactured in India for Indian homes that deserve energy independence.
