Why APsystems Microinverters

APsystems offers advanced, powerful solar microinverter technology for residential and commercial systems. The APsystems microinverter solution combines highly efficient power inversion with user-friendly monitoring to bring you reliable, sustainable energy. Our proprietary system architecture increases solar harvest and ensures maximum output for PV arrays, and our strong commitment to Research & Development continues to bring new technologies and products to the marketplace.

  • Powerful

    APsystems Microinverter technology maximizes power generation for each module in the PV array, boosting system efficiency by up to 20 percent compared to conventional “string” systems

  • Smart

    When combined with the APsystems Communicator and APsystems Monitor, the APsystems Microinverter lets you track the performance of each module in your PV array through any web-enabled device.

  • Cost Effective

    A single APsystems YC500 microinverter unit handles two PV modules, significantly lowering installation and balance-of-system costs. Our fourth-generation YC1000 handles 3 or 4 modules per unit, enabling large-scale, 3-phase commercial solar at an unprecedented price point.

  • Safe

    APsystems Microinverters tie directly to the low-voltage DC module, enhancing homeowner safety and eliminating the possibility of high-voltage “arc” fires. All APsystems products undergo rigorous factory testing, evaluation and field tracking, and are built to a 25-year design life.

APsystems ranks no. 2 in global market share among independent microinverter suppliers.

What Our Partners Say

“After many years researching on different PV technologies available in the market, we are very proud to work exclusively with APsystems microinverters, it was a right decision for us as a Distributor because we benefit the Installers, Resellers and End Users with easier Installation, better warranty, better solution with a very competitive price.”


“Once again, APSystems has raised the bar in the MLPE industry with their new YC600, staying ahead of the curve for future higher-output solar panels. The standard 25-year warranty gives our clients to provide peace of mind.”

Chris Palmergot solar?,

“We are always looking for cutting-edge technology in order to offer the best solutions. Our technology partners in the U.S. like APsystems always provide us with the best quality products.”

Oscar Jiménez VelázquezDirector General, Advance Green Power, Mexico

“This is the most northern grid-tied solar energy system in the Americas and with such a remote installation, we needed a 3-phase inverter that offered the best combination of performance, reliability and price. The APSystems inverter was clearly the best choice.”

Rob BaxterVREC Solar,

“APsystems offers the most advanced microinverters on the market today, so adding them to our product offerings is a natural. Our installers and end customers will be impressed by the power and reliability the APsystems solution brings to their solar systems.”

Jesse StubbsCEO, Clean Energy

“APsystems has the perfect mix of reliability, price and service as a vendor. Our installers love the ease and speed of installation, and not having to worry about messy and expensive cables. Our goal is to make APsystems the No. 1 microinverter in Canada.”

Matthew LisacDirector of Operations, National Solar Distributors Edmonton,

“Working with APsystems significantly improved the net profit on the installation due to a decrease in labour time compared to string inverters. Winning this project was highly competitive, and knowing our install times with APsystems was very valuable in ensuring our bid was as accurate as possible while protecting our margins.”

Alex StuartSycamore Energy,

“We are choosing APsystems as our microinverter because they are second to none in their functionality, efficiency and durability. Their production specifications are becoming the benchmark of what a microinverter should be able to do and produce.”

Ty SimpsonDirector of Sales, Bland Solar &

“With APsystems and our third-party financing, we are taking an important step towards simplifying and lowering costs of PV system ownership for residential customers.”

Stephane DufrennePresident, Upsolar

“APsystems Microinverters are much easier to install than the other ‘major’ company’s inverters. There is no expensive trunk line to stock, as the AC lines are attached to inverters. Also, there is one inverter per two modules, so only half the inverters to install and ground.  With one inverter per two modules, it allows for an easy install for various layouts.”

John Harleyvice president of production, Brimma Solar

“APsystems is leading the industry in solar microinverter innovations. Its revolutionary approach of individualized, maximized microinverters paired with its quality products and ease of installation is what separates it from the crowd.”

Bill Beedonmarketing and business development manager, Next Generation Energy

“APsystems microinverters made this project successful because of their easy installation. Both microinverter and string systems were initially considered, and APsystems decreased cost and complexity.”
