In-Built Lithium Energy Storage System — 1350–2500VA
The Electrent In-Built Lithium ESS is a next-generation home and office energy storage solution. Unlike traditional inverter + battery setups that require separate battery banks, external wiring and regular water top-ups, the In-Built Lithium ESS combines everything into a single compact wall-mountable unit. The built-in LiFePO4 battery delivers up to 7 hours of backup with zero maintenance, elegant design and a near-instant switchover time that protects even sensitive IT equipment.
Available in two models — 1350-100/12.8V (1200VA) and 2500-100/25.6V (2500VA) — the system uses BIS certified A-Grade LiFePO4 cells with an intelligent 100A BMS. It supports both Wide UPS (W-UPS) mode for wider voltage tolerance and standard UPS mode for sensitive equipment.
