Big power and large capacity

The 5000W mega output power can meet multiple high-power appliances running simultaneously. With a large battery capacity of 19.4 kWh, it is enough to ensure that you can power your daily life for 1-2 days during power outages.

Reduce your bills

The combination of the HESS-12HY and solar panel system is the perfect solution for powering your home. When the solar system generates too much electricity, store electricity in the HESS-12HY instead of wasting it. When the solar system can’t meet your electricity needs, let the battery power join.

Off-grid or grid-connected?

The price of electricity, local subsidy policies, weather, and other factors change in real time, so you need to make timely adjustments according to the actual situation, switching back and forth between grid-connected and off-grid modes.

Achieve power independence

In modern society, power outages are unacceptable. HESS-12HY also can be seen as a backup power source for your home, which allows you to rest easy in the event of power outages and natural disasters, without the anxiety of no electricity available.
