Built by an Electrician.
Not a Sales Team.
Walter Ellard founded SunFusion Energy Systems after 40+ years in the electrical and energy industry. Every system we build goes into someone's home where their family lives. That's why we refuse to compromise on safety or quality.
"Every system I install goes into someone's home where their family lives. I refuse to compromise on safety or quality. That's not marketing — that's why I sleep at night."
LiFePO₄ Exclusively
After losing $3M+ to counterfeit cells, we only use Hithium 314Ah Grade-A LiFePO₄. Zero thermal runaway. Zero NMC. The chemistry trusted in aircraft and medical devices.
9% Failure Rate
Industry average is 30–60%. We've achieved under 9% by engineering out every failure point. Zero field failures since ECHO 3.0 launched in 2023.
C-10 License #1053778
Fully licensed C-10 Electrical Contractor. 40+ years experience. Walter holds a Journeyman Electrician certification since 1990. Has built systems up to 2MW.
We Use Our Own Systems
Walter runs SunFusion systems at his own home and office. He monitors them daily with SunFusion Monitor. If it's not good enough for his family, it doesn't ship to yours.
Manufacturer + Installer
We don't just install — we design and build the ECHO battery systems and Guardian enclosures. Vertical integration means quality control from cell to customer.
Nationwide + Worldwide
Installation in San Diego, Riverside, and San Bernardino Counties. Product sales ship to all 50 states and internationally.
No call centers. No scripts. Just honest answers from people who've been doing this for 40+ years.
Mr. Ellard reviews every message and will get back to you.
