Seemed like just the other day that lithium-ion batteries started to attach to solar PV systems, mostly the nickel-manganese-cobalt (NMC) variety. Cut to 2022, and, according to the manufacturers we reached out to for this year’s Buyer’s Guide, lithium iron (ferrous) phosphate (LFP) has emerged as the trendiest battery chemistry on the market for residential and commercial and industrial (C&I) solar + storage systems. Another trend you’ll note is more/new battery options provided by larger brand names in effort to be a one source solutions provider. Peruse the list below for yourself, featuring options from 18 providers. Note: Our accompanying Energy Storage System Buyer’s Guide will be out in August.
