Signs you need battery storage
If any of these sound familiar, it might be time to talk to a pro.
- Power outages disrupt your home
- You want to store excess solar energy
- Time-of-use rates are eating into savings
- You want full energy independence
How it works
Our process is simple and stress-free.
- 1
Energy Assessment
We analyze your energy usage, solar production, and backup needs to right-size your battery system.
- 2
System Design
We design a battery configuration that covers your critical loads during outages and optimizes solar self-consumption.
- 3
Electrical Preparation
If needed, we upgrade your electrical panel and install a critical load subpanel for seamless backup switching.
- 4
Installation
Professional installation of your battery system, integrated with your existing or new solar array.
- 5
Configuration & Training
We configure your system's backup and optimization settings, and walk you through the monitoring app.

A single battery (13–15 kWh) powers essential loads for 8–12 hours during outages, and pairing battery with solar lets you store excess daytime energy instead of sending it to the grid. Epex installs Tesla Powerwall, Enphase IQ, and Franklin WH systems with a 10-year manufacturer warranty.
Energy Independence for Your Home
A home battery stores excess solar energy for use at night, during outages, or when utility rates are highest. Combined with solar, a battery system puts you in full control of your energy.
How Battery Storage Works
During the day, your solar panels generate more electricity than your home uses. Without a battery, that excess goes to the grid for a small credit. With a battery, you store it and use it when you need it most.
Best Battery Options for New Mexico
- Tesla Powerwall 3 — 13.5 kWh capacity, built-in inverter, sleek wall-mount design
- Enphase IQ Battery 5P — Modular design, scales easily, pairs seamlessly with Enphase microinverters
- Franklin WH — 13.6 kWh, whole-home backup capable, excellent app monitoring
When to Add a Battery
The ideal time is during your initial solar installation — it reduces installation costs and ensures your system is designed for storage from the start. But we can retrofit batteries to any existing solar system.
What our customers say
After the power outages last winter, we added battery storage to our existing solar system. Epex made it seamless — same crew that did our original install came back and had everything running in a day. Total peace of mind now.
Frequently Asked Questions
A single battery (13-15 kWh) typically covers essential loads — lights, refrigerator, Wi-Fi, medical equipment — for 8-12 hours. Multiple batteries extend this for whole-home backup.
No, but pairing battery with solar maximizes value. A standalone battery can still provide backup power and help you avoid peak electricity rates.
We install Tesla Powerwall, Enphase IQ, and Franklin WH batteries. We recommend the best fit based on your system and needs.
Yes. Home batteries qualify for the 30% federal tax credit when installed with or charged by a solar system.
Your battery automatically disconnects from the grid and powers your home within milliseconds. When grid power returns, it reconnects and resumes normal operation.
Home battery systems cost $10,000-$20,000 installed. After the 30% federal tax credit, net cost drops to as low as $7,000. The exact price depends on battery capacity and whether electrical upgrades are needed. We provide detailed quotes after assessing your home.
Yes. We retrofit batteries to existing solar systems regularly. If your solar uses Enphase microinverters, an Enphase IQ battery pairs seamlessly. For other inverter brands, Tesla Powerwall or Franklin WH work well. We assess compatibility during a free consultation.
Most home batteries are warrantied for 10 years and designed to last 15+ years. Tesla Powerwall is warrantied to retain 70% capacity over 10 years. Battery degradation is gradual, so your system stays useful well beyond the warranty period.
For homes that experience power outages or want energy independence, battery storage is highly worthwhile. PNM's net metering currently credits excess solar, but battery lets you use your own power at night instead of buying from the grid — providing both savings and outage protection.
