Be Annoyed with the increasingly expensive electricity bills? Or furious about the power system that crashes from time to time? Take it easy! The Dowell HESS-12HY home energy storage system can make these troubles disappear from your life. By pairing a solar panel system with HESS-12HY, you can achieve energy independence, reduce your home’s electricity costs, maximize the efficiency of your solar panel usage, and prepare in advance for periods of high-demand electricity use and unexpected power outages.
All-in-one design
This design reduces many complicated installation steps and avoids fumbling to connect various interfaces and harnesses. It is also easy to carry and saves time for rewiring. With its IP 54 protection grade, the HESS can operate normally both indoors and outdoors, without special maintenance.
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. If facing a time-of-use tariff charging policy, you can store cheap grid electricity in your HESS-12HY and then use it when expensive, which is equivalent to using electricity at the cheapest price all the time.
Off-grid or grid-connected?
You don’t need to make a choice. . HESS-12HY can switch freely between two working modes, which allows for a better return on investment. 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.
