Lithium iron phosphate (LiFePO4) batteries have become the standard for modern solar installations, and for good reason. Compared to older lead-acid batteries, lithium batteries last 5–10x longer, charge faster, take up less space, and can be discharged much deeper without damage.
Brands like Deye, Dyness, Megatron and Freedom Won all offer reliable, warrantied lithium battery packs that we stock and install. Talk to us about which battery brand and capacity fits your budget and backup needs.
