APsystems: The Original Multi-Module Microinverter (M3™) Pioneer

In the landscape of solar innovation, APsystems stands out not just as a participant, but as the trailblazer that set the course for others to follow. Founded in the tech cradle of Silicon Valley in 2010, APsystems introduced the world to the concept of multi-module microinverters (M3), a revolutionary step that redefined solar power conversion efficiency and scalability.

Setting the Standard in Solar Technology

Before APsystems’ groundbreaking introduction of M3 microinverters, the industry standard was limited to single-module microinverters. By expanding the capability to serve 2 to 8 PV modules simultaneously, APsystems didn’t just innovate; it created a whole new paradigm in solar technology. This visionary approach has since become the blueprint for the industry, with every new entrant looking to the model established by APsystems as the gold standard.

A Legacy of Leadership and Innovation

APsystems’ journey from a Silicon Valley startup to a global solar leader is marked by a series of pioneering achievements. With over 5GW of solar power conversion devices shipped worldwide, including approximately 4 million microinverters, APsystems has played a pivotal role in connecting more than 15 million solar panels across the globe. This vast network is a testament to the trust and reliability that the brand has cultivated over the years.

The Imitation Game: A Sign of True Leadership

The sincerest form of flattery in the business world comes through imitation. As the original manufacturer of M3 microinverters, APsystems has seen its innovative approach replicated by others in the industry. This trend underscores APsystems’ position at the forefront of solar technology, where being the first has set a benchmark that others strive to emulate. However, while imitation may be inevitable, the pioneering spirit and continued innovation of APsystems remain unmatched.

Beyond Firsts: A Commitment to Excellence and Sustainability

APsystems’ legacy is not just about being the first; it’s about continuously pushing the boundaries of what’s possible in solar technology. The company’s equipment has generated over 4.5 TWh (four trillion watt-hours) of clean, renewable energy, contributing significantly to global sustainability efforts. Selling into more than 100 countries, APsystems’ global impact is a reflection of its commitment to providing reliable, efficient, and innovative solar solutions.

 

Choose the Original, Choose APsystems

In a world where the distinction between the original and the imitator can be blurred, APsystems stands out for its authenticity, innovation, and leadership in the solar industry. By choosing APsystems, customers are not just selecting a product; they are investing in a legacy of pioneering achievements and a future of sustainable energy solutions.

As we continue to lead the solar revolution, we invite you to join us in embracing the power of the sun with APsystems, where innovation meets sustainability. Together, we’ll build a greener future powered by the original multi-module microinverter (M3) technology that continues to set the standard in solar energy conversion.

Small Solar. Big Business Opportunity.
DIY, balcony and small-scale solar are creating a new category of customers and a new revenue opportunity for installers.
Consumers are looking for simple, flexible solar solutions for balconies, patios, garages, gardens and other spaces that traditional rooftop systems may not serve. With the APsystems EZ1, installers can meet that demand instead of losing customers to off-the-shelf DIY products.
EZ1 gives installers new ways to generate business:
• Offer plug-in solar kits and ready-to-go packages 
• Take on quick, small-scale installations 
• Provide paid installation and setup support for DIY customers 
• Add panels for customers whose existing system no longer covers their usage 
• Offer an immediate solar option while customers wait for a full installation 
• Build relationships with new customers who may expand later 
EZ1 fits alongside your existing residential and commercial business without changing your core operation. It gives you an easy entry point into small-scale solar and a way to turn growing DIY interest into real revenue.
Don’t compete with the DIY solar category. Make it part of your business.

MATT MAKES SOLAR EZ: ASK MATT
What happens to the EZ1 during a power outage?
The short answer: it shuts down, just like it should.
The EZ1 meets UL 1741 SB requirements and includes anti-islanding protection. If the utility grid goes down, the EZ1 automatically stops producing power—helping prevent electricity from backfeeding onto utility lines and protecting the crews working to restore power.
Once utility power returns and the required five-minute safety period is complete, the EZ1 automatically starts producing again.
New to the EZ1? Watch Matt’s first video to see how simple plug-in solar can be: https://youtube.com/shorts/jFhz5g4a6rE?feature=share

Keep your solar power at home.
In areas where sending excess solar energy back to the grid may be restricted—or for homeowners who simply prefer not to—the optional APmeter adds automatic zero-export control to your EZ1 system.
The APmeter monitors how much electricity your home is using. When your EZ1 begins producing more solar power than your home needs at that moment, the APmeter automatically adjusts its output to help prevent excess power from backfeeding to the utility grid.
✓ Monitors your home’s power use
✓ Matches EZ1 output to current energy demand
✓ Helps prevent excess solar from backfeeding to the grid
✓ Works automatically with your EZ1
EZ1 + APmeter: plug-in solar with smart zero-export control.
The APmeter is sold separately and requires installation at the electrical panel by a qualified professional. Always verify applicable utility rules, permitting requirements and electrical codes before installation.

Need onsite training? APsystems does that!
Great products are only part of the equation. Having the knowledge and support to install them with confidence matters, too.
That’s why APsystems takes training beyond the screen and into the field. Teddy Hodges, Head of U.S. Training and Education, works directly with solar professionals to share hands-on product knowledge, installation best practices and the practical know-how that helps crews get systems up and running right the first time.
Better training. Smoother installs. Stronger solar teams.

Yes, you really can plug solar panels directly into a standard 120V outlet!  Thanks Joe for putting the APsystems EZ1 to the test and showing just how simple plug-in solar can be.
See the EZ1 in action, from connecting the panels to producing power and monitoring performance through the app.

Today, we pause to remember the lives lost on September 11, 2001, and to honor the courage of the first responders, service members and everyday people who stepped forward in the face of unimaginable tragedy.
We remember those we lost, their families and all those forever impacted by that day.

How simple is plug-in solar? Solar Surge put the APsystems EZ1 to the test.
Watch as Joe Ordia connects two solar panels to one EZ1 microinverter, plugs it into a standard 120V outlet and immediately starts producing around 480 watts of power.
That solar energy helps power whatever is drawing electricity in the home at that moment—reducing the amount needed from the grid. Joe also walks through connecting the EZ1 to Bluetooth and Wi-Fi for real-time monitoring through the app.
