Home battery installations run $18,000-$110,000 over 1-2 weeks depending on system complexity and permit requirements. Federal 30% tax credit applies to standalone batteries from 2023 onward. Air-conditioning is the biggest sizing variable; a 5-ton AC drains a single battery in 2-3 hours.
We analyze your home's energy usage, existing solar system (if any), and backup power needs. Our experts identify which circuits and appliances you want to power during outages.
Outcome:
A complete understanding of your energy needs and the ideal battery solution for your home.
Based on your assessment, we design a battery system sized to meet your backup requirements. We'll recommend premium options like Tesla Powerwall, Enphase, or Franklin Home Power, explaining the benefits of each.
Outcome:
A tailored battery proposal with clear pricing, capacity details, and expected backup duration.
Buildda handles all permit applications and helps you navigate California's Self-Generation Incentive Program (SGIP) for potential rebates. We ensure your system qualifies for all available incentives.
Outcome:
All permits secured and incentive applications submitted to maximize your savings.
Our certified technicians install your battery system in the optimal location -garage, exterior wall, or dedicated space. We ensure proper ventilation, weatherproofing, and seismic mounting for California conditions.
Outcome:
A professionally installed battery unit positioned for safety and optimal performance.
We connect your battery to your electrical panel and configure the critical load panel if needed. Integration with existing solar systems is seamlessly handled to optimize energy flow.
Outcome:
Your battery is fully integrated with your home electrical system and solar setup.
Our team programs your battery management system, setting backup reserves, time-of-use optimization, and grid interaction preferences. We simulate outage conditions to verify seamless switchover.
Outcome:
A fully configured system that automatically responds to your energy needs and outages.
After passing inspection, we walk you through the monitoring app and explain all features. You'll know exactly how to track energy storage, adjust settings, and monitor your backup status.
Outcome:
Complete control over your home energy storage with continuous monitoring capabilities.
Buildda registers your manufacturer warranty (typically 10+ years) and our workmanship warranty (see contract for terms). We provide maintenance guidance and remain available for any questions or service needs.
Outcome:
long-term confidence with comprehensive warranty coverage and ongoing support.

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.
