Industrial ESS
50kWh-1MWh+ container/cluster ESS for C&I and grid
Home Energy Storage System 5-20kWh
The XGW home energy storage system pairs stackable 48V/51.2V LiFePO4 battery modules (5-20kWh) with hybrid inverters from 3kW to 15kW, giving households solar self-consumption, peak shaving and whole-home backup. Wi-Fi app monitoring shows real-time energy flow, while the stackable design lets capacity grow with the household - start at 5kWh, expand to 20kWh by adding modules.

Frequently Asked Questions
What size home ESS do I need?
A typical household starts with 10kWh covering evening consumption; all-electric homes or EV charging usually justify 15-20kWh. Our sizing guide walks through daily kWh usage, PV capacity and outage autonomy targets.
Can I expand the system later?
Yes. The stackable module design lets you start at 5kWh and add modules up to 20kWh without replacing the base unit.
Does the system work during a blackout?
Yes. With a hybrid inverter, the system automatically islands the home and supplies backup power from battery and solar within milliseconds.
Which inverters are compatible?
Our battery modules integrate via CAN/RS485 with major hybrid inverter brands, and we supply matched XGW hybrid inverters (3-15kW) as a complete system.
