Suntherra Battery
1 / 5
Unlock true energy independence with our Stackable Home Energy Storage System — a powerful, modular solution designed for residential solar storage, backup power, and off-grid living.
Each 5.12kWh LiFePO4 battery module can be stacked from 1 to 5 units, delivering a scalable capacity of up to 25.6kWh to match your household's unique energy demands.
This all-in-one ESS integrates a high-efficiency 5000W pure sine wave inverter and a 5500W MPPT solar charge controller (120–500VDC input range), enabling seamless compatibility with most residential PV systems.
With a 90% depth of discharge (DOD), 100A discharge current, and built-in UPS functionality, this system ensures reliable, uninterrupted power for your home — day or night, on-grid or off-grid.
