Home Battery Storage Installation

Energy Independence and Backup Power

Home battery installations in LA run $18,000-$28,000 for a single 13.5 kWh system (Tesla Powerwall or equivalent), $35,000-$55,000 for whole-home backup with 2-3 batteries, and $65,000-$110,000 for off-grid-capable arrays. Federal 30% tax credit applies to standalone batteries from 2023 onward.

Battery systems run $18,000-$110,000 depending on capacity and panel readiness. Common batteries: Tesla Powerwall, Enphase IQ Battery, Generac PWRcell. Solar pairing maximizes value under California's NEM 3.0 export rates (which favor self-consumption over export). Air-conditioning is the biggest sizing variable, since a 5-ton central AC can drain a single battery in 2-3 hours, which is why whole-home backup with AC usually requires multiple batteries. Cost variance comes from battery capacity sized to whole-home vs. critical-loads (whole-home backup needs 20-30 kWh and panel upgrades to handle the surge of starting the AC; critical-loads - fridge, lights, internet, medical equipment - typically lands at 10-13 kWh on a sub-panel), solar pairing (existing solar significantly improves battery economics; new battery + solar bundle qualifies for the federal 30% Residential Clean Energy Credit through 2032), panel readiness (most pre-2010 panels need an upgrade to 200A service to support both the battery interconnect and modern loads - about $4,500-$9,000), and permit + utility approval (SGIP rebates are available for qualifying installs but require utility application). Under California's NEM 3.0, exporting solar to the grid pays out at a fraction of retail rates; the math now favors storing your own midday solar in a battery and using it at the 4-9 PM peak rate window.
