Battery Backup Installation in Denver, CO

Apollo Energy is Denver’s trusted installer for home battery backup systems. We design, install, and service battery storage solutions from Tesla, Enphase, and FranklinWH — helping Colorado homeowners protect against power outages, reduce electricity bills, and take control of their energy.

Why Denver Homeowners Are Adding Battery Backup

Colorado’s Front Range has experienced multiple extended power outages in recent years, leaving hundreds of thousands of homes without electricity for days at a time. A home battery backup system keeps your lights on, refrigerator running, and critical devices powered — even when the grid goes down.

Beyond outage protection, battery storage lets you store excess solar energy during the day and use it during Xcel Energy’s peak pricing windows (typically 5–9 PM). This time-of-use optimization can significantly reduce your monthly electricity costs, especially as utility rates continue to rise.

Battery Systems We Install

Tesla Powerwall

The Tesla Powerwall 3 delivers 13.5 kWh of usable storage with 11.5 kW of continuous power output — enough to run most Denver homes through an overnight outage on a single unit.

How Battery Backup Installation Works

1. Free consultation and energy audit — We review your electricity usage, utility rate plan, backup priorities, and existing solar system to recommend the right battery size and brand for your home.

2. System design and permitting — Our engineering team designs your battery system, selects the optimal installation location, and handles all permitting with your local jurisdiction and Xcel Energy.

3. Professional installation — Our licensed electricians install your battery system, typically in one day. We handle all electrical connections, panel upgrades if needed, and system commissioning.

4. Xcel interconnection and monitoring setup — We complete Xcel’s interconnection paperwork, enroll you in applicable rebate programs, and set up your monitoring app so you can track battery performance in real time.

Frequently Asked Questions

How long will a home battery last during a power outage?

A single Tesla Powerwall (13.5 kWh) can power essential loads — lights, refrigerator, Wi-Fi, phone charging — for 12–24 hours depending on usage. With solar panels, your battery recharges daily, providing continuous backup through multi-day outages. For whole-home coverage including HVAC, most homes need 2–3 battery units.

Can I add a battery to my existing solar system?

Yes. All three battery brands we install — Tesla Powerwall, Enphase, and FranklinWH — can be retrofitted to existing solar installations. Enphase and FranklinWH are AC-coupled and work with any inverter brand. Tesla Powerwall 3 includes an integrated inverter and may require a panel reconfiguration. We evaluate your current system during the free consultation.

Is a home battery worth it in Colorado?

For most Denver-area homeowners with solar, yes. Between Xcel’s time-of-use rate savings ($300–$600/year), the strong incentive stack, and increasing grid instability, most battery systems pay for themselves in 7–10 years while providing immediate backup protection and energy independence.

What is Xcel's Renewable Battery Connect program?

Renewable Battery Connect is Xcel Energy’s virtual power plant (VPP) program. You receive an upfront rebate of $350/kW (up to $5,000) plus $100/year for five years. In exchange, Xcel can discharge up to 60% of your battery capacity during periods of high grid demand. Your battery remains fully available for outage backup at all times.
