Licensed Contractor #1063682

Battery Storage Contractor — Fresno, Clovis & Madera

We are a licensed California electrical and solar contractor specializing in residential battery storage systems. Every install is permitted, inspected, and backed by manufacturer warranties. We handle the full project — design, permitting, installation, PG&E interconnection, and commissioning.

New Battery Storage Installation

Standalone battery or solar-paired storage. We size the system to your home, pull permits, and coordinate PG&E interconnection from start to finish.

Battery Retrofit to Existing Solar

Already have solar? We assess your current inverter and add a Tesla Powerwall, Enphase IQ Battery, Franklin WH, or Sol-Ark hybrid system.

Whole-Home vs. Partial Backup

We design your system around your priorities — critical loads only or full whole-home backup. Every quote includes a load analysis.

PSPS & Outage Protection

PG&E Public Safety Power Shutoffs are common in Fresno and Madera Counties. Battery storage keeps your home running when the grid goes down.

Grid-Tied & Off-Grid Storage

Grid-tied systems with backup capability, or fully off-grid configurations for rural properties. Sol-Ark hybrid inverters supported.

Time-of-Use Optimization

Charge during off-peak hours, discharge during peak PG&E rate windows. Reduce your bill even without solar.

Why a Home Battery

The Central Valley Gets Outages. Be Ready.

PG&E Outages Are Getting Longer

PSPS shutoffs, wildfire season, and aging grid infrastructure mean Central Valley homeowners lose power more often than ever. A battery keeps your home running automatically.

Charge at Night, Use During the Day

A battery charges from your solar system or the grid and discharges when you need it most — during outages or when your solar isn't producing.

Store What Your Solar Produces

Solar panels produce the most power midday. A battery stores that excess energy so you can use it at night instead of drawing from the grid.

Common Questions

Battery FAQs

It depends on your system size and what you're powering. A single 10 kWh battery can run your lights, fridge, phone chargers, and a few fans for 12–24 hours. Pair two batteries together and you can run most of your home for a full day or more. We size the system to your priorities.

No — you can install a battery without solar. It charges from the grid at off-peak rates and discharges during peak hours or outages. That said, pairing solar with a battery gives you the most savings and the best backup protection.

We install Tesla Powerwall, Enphase IQ Battery, Franklin WH aPower, SolarEdge Energy Bank, and Sol-Ark hybrid inverter systems. We recommend the right system based on your home size, energy usage, and goals. All systems we install carry manufacturer warranties of 10 years or more.

Yes. All systems we install include automatic transfer switching. When the grid goes down, your battery kicks in within milliseconds — you may not even notice the switch.

In most cases, yes. We assess your existing inverter and panels to determine compatibility. Some older systems require an inverter upgrade, which we can quote alongside the battery.
