Ten kilowatt-hours at the voltage that physics rewards most. The 51.2V 200Ah Solar Inverter Battery functions as a precision instrument within the energy storage ecosystem. Every cell operates at its ideal electrochemical potential. Every watt-hour enters and exits with minimum conversion loss. Every charge cycle deposits energy with maximum acceptance efficiency. Chemistry and engineering in perfect alignment.

LiFePO4 prismatic cells of the largest format available in the Uttam Electric portfolio constitute the foundation. Configured in a 16-cell series string, they produce a pack with 10.24 kWh of nominal stored energy. For a typical Indian household, this figure translates to complete overnight autonomy. Sunset to sunrise without grid dependency. For a commercial establishment, it represents hours of critical load backup that no lead-acid bank could match in the same volume.

At 75 kg within a 470 x 365 x 230 mm housing, the battery’s low-profile design at 230 mm height permits placement under workbenches, inside storage cabinets, or flush against walls where taller enclosures would protrude. Mounting hardware supports both floor-standing and wall-adjacent configurations. The generous internal spacing ensures optimal thermal management at this capacity level.

The smart BMS tracks state of charge, state of health, cumulative cycle count, and cell-level statistics. This data integrates with compatible hybrid inverter platforms to enable intelligent load scheduling. Bluetooth, RS485, CAN, and UART interfaces export diagnostics to mobile and desktop monitoring systems. Five protection layers cover over-voltage, under-voltage, overcharge, deep discharge, and temperature. Charging at 40A finishes in approximately 5 hours. IP69 rated.

The 60-month warranty with replacement and repair coverage reflects the durability that LiFePO4 chemistry and intelligent BMS management deliver in combination. For homes and businesses investing in rooftop solar, this battery converts panel output into genuine energy independence. Manufactured in India for a solar-powered India.
