How much does a solar plus battery system cost?

SunFusion Sol-Ark systems start at $5,999. ECHO 3.0 LiFePO4 batteries start at $3,175. The Guardian whole-home system starts at $27,373. The 30% federal tax credit (IRA) applies to all systems, significantly reducing net cost.

What makes SunFusion's batteries better than competitors?

SunFusion uses LiFePO4 (lithium iron phosphate) chemistry — zero thermal runaway risk, 16,000+ cycle life vs 3,000-5,000 for NMC competitors. Our industry-leading 9% failure rate compares to the competitor average of 30-60%.

Is SunFusion licensed to install solar in California?

Yes. SunFusion Energy Systems Inc. holds California C-10 Electrical Contractor License #1053778. Walter Ellard, founder and CEO, has 40+ years of electrical and energy industry experience.

What is the ECHO 3.0 LiFePO4 battery cycle life?

The ECHO 3.0 LiFePO4 battery is rated for 16,000+ charge cycles — approximately 43+ years of daily use. This is 3-5x longer than NMC battery systems used by most competitors, and means you will likely never need to replace your battery bank.
