When a single 12V battery is not enough, the answer is not two batteries wired together. The answer is a purpose-built 24V pack. The Uttam Electric 24V 100Ah Solar Inverter Battery eliminates the complexity of series-connected 12V units. One pack. One BMS. One set of connections. Simplicity is reliability.

The 24V configuration is the standard for mid-range solar inverter systems across India. Homes running air coolers, refrigerators, and multiple fans during outages need more than 12V can deliver. The 24V platform provides the voltage headroom that larger inverters require while keeping the system architecture straightforward.

Built with 3.2V 105Ah LFP prismatic cells, this pack delivers 100 ampere-hours of deeply cyclable energy. Overcharge protection monitors every charging session, whether the power comes from solar panels, grid chargers, or hybrid systems. The BMS ensures cells never exceed safe voltage thresholds regardless of the charging source.

At 25 kg and 290 x 200 x 260 mm, the battery is compact for its capacity class. It replaces a pair of 12V lead-acid batteries while weighing less than a single one of them. Installation is faster. Wiring is simpler. Maintenance is virtually zero.

The IP65/67 rating handles every installation scenario from air-conditioned server rooms to unventilated utility closets. Charging takes 5 to 10 hours. The 60-month warranty provides half a decade of coverage.

For homes upgrading from 12V to 24V solar systems, this is the cleanest path forward. One battery. Five years of warranty. Zero maintenance. Manufactured in India for the solar revolution happening on Indian rooftops.
