Meet the Generac PWRcell 2: Smarter Solar Storage for Your Home

If you’re adding battery backup to your solar system, you need something powerful, reliable, and built to perform in North Carolina’s coastal climate. That’s where the Generac PWRcell 2 comes in. This next-generation home battery offers more storage, more power, and more flexibility—so your home stays energized even when the grid doesn't.

Cape Fear Solar Systems was among a select group of installers nationwide chosen to install the initial PWRcell 2 trial units. That early hands-on experience gave us a deep understanding of how this system performs in real homes, with real weather, and real backup needs. Now, we’re proud to offer this cutting-edge solution to homeowners who want smarter solar storage.

Why Battery Backup Matters More Than Ever

Power outages aren’t just inconvenient anymore, they’re expected.

Between hurricanes, summer storms, and aging grid infrastructure, many North Carolina homeowners experience regular disruptions to their power. A battery system can change that. With solar plus storage, you can:

• Keep critical appliances like refrigerators, lights, Wi-Fi routers, and medical equipment running
• Avoid the hassle, noise, and fumes of a gas-powered generator
• Maintain peace of mind during hurricane season and beyond

Solar + battery = real resilience. Explore how backup batteries give your solar system real power.

What’s New in the Generac PWRcell 2?

This isn’t just an upgrade. It’s a leap forward in home energy technology. The Generac PWRcell 2 offers:

• Up to 18 kWh usable energy capacity in a single cabinet, scalable in 3 kWh increments
• 10 kW continuous power and 15 kVA peak inrush power, which can support large loads like a 5-ton A/C unit
• A Smart Disconnect Switch (SDS) that transitions backup power automatically and supports up to 200A loads
• Modular scalability for larger homes—up to 72 kWh of storage using four cabinets and two inverters
• Smart thermostat integration with Ecobee, improving energy efficiency during outages
• Real-time insights and remote monitoring through Generac’s PWRview app

Seamless Integration With Your Solar System

The PWRcell 2 works with both new and existing solar arrays, charging directly from the sun. That means no reliance on fuel deliveries or manual switching when the grid fails.

At Cape Fear Solar, we ensure that every system we install meets coastal NC wind code requirements and is built to perform through storms, humidity, and salt air exposure. 

How the PWRcell 2 Compares to Other Systems

We’ve worked with a range of solar batteries, and while every home is different, here’s why the PWRcell 2 stands out:

• More capacity in a single unit than many competitors
• Flexible modular upgrades for growing families or increased energy needs
• Seamless pairing with whole-home loads and EV chargers
• Smart energy management with Generac’s built-in PWRmanager

Is the Generac PWRcell 2 Right For You?

If you're exploring battery backup, ask yourself:

• Do I want to stay powered during long outages?
• Do I have (or plan to install) high-energy appliances like electric stoves or EV chargers?
• Do I want a backup system that grows with me as my energy needs change?
• Do I want real-time insight and control over my home’s power?

If the answer is yes to any or all of these, the PWRcell 2 is likely a strong fit.
