About Us

Best Energy Storage System in the US

SunFusion Energy Systems has all of our competitors beat! Just one of SunFusion Energy Systems cabinets can hold 24kW of continuous power and peak at 40kW, ensuring you are able to keep your entire home powered through blackouts or planned outages from the utility. Most battery systems only keep your power on as long as the sun is out and Solar PV is connected, but when the sun goes down, how long do they last? Visit us in San Diego and get to know more about our installation services. You can also contact us at (800) 544-0282 and we'll be glad to help with any inquiry.
