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. 
POWERFUL
APsystems microinverter installations are typically 5-15 percent more efficient than comparable “string” systems. That’s like having more solar modules on your roof with the same-sized array.
SMART
The APsystems Energy Monitoring and Analysis, or EMA software allows around-the-clock management of your solar array through any web-enabled device, like your home computer or smartphone.
COST EFFECTIVE
The APsystems microinverter is the affordable, flexible solution for your solar power array. The compact, independent design allows easy installation on virtually any available surface, and because it is an integrated system, the APsystems microinverter solution simplifies system design. Solar arrays can be easily expanded at any time, hassle-free.
The savings don’t stop there – APSystems microinverters track multiple PV modules (2 panels per micro in this kit) meaning you need half the inverters and half the installation means real cost savings for your residential or commercial solar power system.
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 DS3 Microinverter Features:
What is so unique about these new microinverters? The DS3 series utilizes a new architecture that can manage far higher capacities of PV modules than conventional 1:1 microinverters.The DS3-S and DS3-L have also been specifically designed to maximize the output on each residential circuit. Compared with competing devices, the DS3-S has up to 37% more AC output and the DS3-L up to 60% more output power per channel than conventional microinverters. For many installers around the world, the new DS3 series has become a strong competitive advantage helping them save money while winning more business.

APsystems – ECU-R, Zigbee CommunicationGateway for YC600I
The APsystems ECU-R is a state-of-the-art Energy Communication Unit. It is the information gateway for your microinverters. The unit collects module performance data from each individual microinverter and transfers this information to an internet database in real time, requiring only a single data and power cable.
Through the APsystems EMA software, the APsystems ECU gives you precise analysis of each microinverter and module in your solar installation from any web-connected device. The APsystems ECU’s integrated http webserver offers the simplest and most flexible network integration of any data logger on the market.
The user-friendly browser-based interface lets you access your solar array in seconds.Key Features
Collects individual module and microinverter statistics
