Solar is about more than just the panels

When planning solar for your home, choosing the right inverter is one of the most important – and often most overlooked – decisions you can make. Solar panels may catch the sun, but an inverter determines how much of that solar power you get to use.


With PWRmicro Solar Microinverters, you’ll capture more clean solar energy for greater efficiency, stronger output and more savings over time.

Squeeze more savings from every drop of sun

Today’s high-output solar panels can produce more power than most inverters can keep up with, leaving potential savings sitting on the roof. With Generac’s microinverter, you can unlock up to 40% more power*  than the industry leading microinverter—turning missed energy into real savings. It’s the simplest way to accelerate your ROI and increase longterm savings.

Maximize Your Solar System Uptime

 

Microinverters keep your system running panel by panel. One issue, like shading, damage, or failure, doesn’t turn into a total system outage.

 


In a traditional string system, your entire solar investment hangs by a single thread. These “string” systems rely on one central inverter, so when one panel is shaded – or fails – the entire system is dragged down.


With microinverters, each panel operates independently. Shade on one panel doesn’t drag down the rest, and one glitch won’t take your whole system offline. Your roof keeps producing, your savings stay protected, and your investment keeps paying you back.

 

Built for the worst, so you get the best

Your roof is a brutal environment, subject to baking heat and freezing storms. With a durable, NEMA 6-rated enclosure, PWRmicros are sealed against water, dust, and debris, delivering dependable performance season after season.

PWRmicros also feature an industry-leading 25year product warranty with 5year labor coverage, providing lasting reliability that millions of homeowners already trust to power their lives.

Smarter control, wherever you are

See exactly how your solar is performing—anytime, anywhere. With real‑time and historical monitoring from your smartphone or tablet, you always have a clear view of your solar energy production. At home, your ecobee smart thermostat puts solar output and outage alerts right on the wall, giving you instant insight into system performance.

And because PWRmicro gives every panel its own “brain,” you get panel‑level visibility that traditional string systems can’t match. Track performance down to the individual panel and take control of your energy.

How Solar Microinverters Work

Capture
1

Capture

Solar panels capture sunlight using photovoltaic (PV) cells, converting it into direct current (DC) electricity.

Convert
2

Convert

A solar inverter, like PWRmicro, is installed underneath the panel to convert DC electricity into alternating current (AC) electricity.

Consume
3

Consume

The AC electricity is now ready to be used by your home, stored in a battery, or sold back to the grid.

FAQs

PWRmicro is Generac’s solar microinverter, which is installed underneath your solar panels and converts the sunlight into usable electricity for your home.

No, PWRmicro works with your solar panels to provide power to your home when the sun is shining. You can add battery storage like PWRcell 2 later and store excess energy from solar, or the grid, which can be used to power your home at night or during outages.

Yes, with microinverters like PWRmicro, each panel operates independently, helping to maintain performance if one panel is shaded or malfunctions.

PWRmicro features a unique 2-to-1 design, so each microinverter connects with two solar panels via independently optimized inputs. You get the reliability and performance benefits of microinverter technology with half the number of inverters.

PWRmicro also provides up to 40% more power than the industry leading product line with 410 W per input.

You can monitor your solar production in real time or over time using your smartphone, tablet, or ecobee by Generac smart thermostat. PWRmicro also provides panel‑level visibility, allowing you to track the performance of each individual panel—something traditional string inverter systems can’t do.

Yes, the PWRmicro solar inverter is designed to fit into a flexible home energy system that allows homeowners to add battery storage or a home generator in the future for backup power and additional energy resilience.

25‑year product warranty and 5‑year labor coverage. See full terms in the Warranty Statement.

By capturing free, clean energy from the sun, your solar panels plus Generac’s microinverter can reduce the amount of electricity you need to purchase from your utility. Actual savings will vary depending on utility rates, energy usage, system configuration, and available incentives.

The Smart Combiner is the communications hub of the PWRmicro system. It manages grid interconnection, monitors system performance, and serves as the bridge to solar battery storage if you add PWRcell 2 later. One Smart Combiner supports up to 28 microinverters.
