105 years of history. A smarter approach to backup power. ⚡🏡

For this Utah homeowner, preserving his historic home means preparing it for the next century.

With a three-tier Fortress Power energy storage system, Lee has taken home energy independence a step further, combining everyday solar management, automatic whole-home backup, and a dedicated solution designed to support essential loads during extended outages of up to two weeks.

Phase 2 of my Fortress Power off-grid shop system goes live Monday.
In this one I’m getting the system mounted and wired, setting up the Guardian and communications, running the temporary shop power connection, and getting everything ready for the next step.
I’m saving the actual commissioning, first power-up, and real load testing for Phase 3.
If you’ve been following the shop build, this is where the power system really starts coming together.

What’s the next step when a commercial site already has solar?

At The Crossings Church in Costa Mesa, an eSpire 280 was integrated with a 260.4 kWdc solar PV system to help manage peak demand and make better use of the site's energy resources.

With Keystone EMS + a Microgrid Controller coordinating energy flows, the system can discharge stored energy during periods of high demand, helping reduce peak grid consumption and manage energy costs. ➡️ https://bit.ly/4jQ6ssO

RE+ is only a month away, and Solar Insure will be in Las Vegas to talk residential warranty coverage.

Homeowners want simplified, long-term protection for their system's most critical components. Solar Insure builds on manufacturer warranties by bringing that coverage together under one warranty, giving installers real backing to offer at the point of sale.

Here's what our Elite Providers say it's done for their business:

- A clear answer when homeowners ask who covers their system in 10 years
- Stronger sales conversations and fewer deals stalled on long-term concerns
- Independent vetting that builds credibility with customers
- Labor coverage that keeps service costs off the installer's books years after install

Stop by booth C4190, or start the show with us at our breakfast with Rello and Fortress Power.

📅 Tuesday, November 17 | 8:30–10:30 AM PST

Your home battery can do more than store energy for later.

Through a Virtual Power Plant (VPP), eligible batteries can support the grid during periods of high demand while potentially earning homeowners incentives, payments, or bill credits.

See how VPPs work and what they could mean for your home energy system. 👆

Managing energy across a commercial site shouldn’t mean managing every asset separately.

Keystone EMS brings batteries, solar, generators, EV charging, facility loads, and the grid together in one intelligent platform, giving operators greater visibility and control over how energy moves across the site.

The result? Smarter demand management, greater opportunities for energy savings, and access to grid services.
