  • 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.

Stephane Dufrenne

“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
John Harley

“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
Frank Rieger

“APsystems is the only microinverter on the market for 300-watt panels with a 25-year warranty. Being twin inverters, APsystems Microinverters are less costly because only one inverter is needed for every two panels. APsystems is the world’s leading brand for microinverters, and we’re very happy with the product.”

Frank RiegerFounder and CEO, Sol-Up
Jeffrey W. Austin

“We are very impressed with the quality of the APsystems product as well as the ease of installation. The YC500 fits a niche we have in the marketplace and it really is the solution we have been looking for. Since there is no need to add a trunk line, the APsystems Microinverters have saved us time and money. It is compact, easy to wire and perfect for our varied system size installations. The dashboard is a welcomed added benefit to our customers.”

Jeffrey W. AustinPresident, GreenSeal Power
