Why Ohio's climate shapes your battery choice
Ohio's continental (humid) climate stresses batteries — both NMC and LFP chemistries lose capacity at -10 C and below. A 13.5 kWh nameplate battery can deliver only 9-10 kWh usable at Ohio winter lows without active thermal management.
For Ohio installs, prioritize batteries with active thermal management (built-in heaters): Tesla Powerwall 3 (operating range -20 to +50 C), LG Energy Solution ESS. Indoor garage installation is also recommended over outdoor wall mount — every 5 C of conditioned space adds 8-12% usable capacity in Ohio winters. At Ohio's $0.15/kWh, battery economics work best when paired with TOU rate plans rather than pure backup use cases.
