YC500A/I Installation/User Manual
APsystems YC500 System Introduction
This integrated system improves safety; maximizes solar energy harvest; increases system
reliability, and simplifies solar system design, installation, maintenance, and management.
APsystems Microinverters maximize PV energy production
Each PV module has individual Maximum Peak Power Tracking (MPPT) controls, which
ensures that the maximum power is exported to the utility grid regardless of the performance
of the other PV modules in the array. When PV modules in the array are affected by shade,
dust, orientation, or any situation in which one module underperforms compared with the
other units, the APsystems Microinverter ensures top performance from the array by
maximizing the performance of each module within the array.
More reliable than centralized or string inverters
The distributed APsystems Microinverter system ensures that no single point of system failure
exists across the PV system. APsystems Microinverters are designed to operate at full power at
ambient outdoor temperatures of up to 149°F (65°C). The inverter housing is designed for
outdoor installation and complies with the NEMA 6 environmental enclosure rating.
Simple to install
You can install individual PV modules in any combination of module quantity,
orientation,different type and power rate.(check our online module compatibility checker called
Edecider or contact APsystems).
The Ground wire (PE) of the AC cable is connected to the chassis inside of the
Microinverter, eliminating the installation of grounding wire (check local
regulation).
Smart system performance monitoring and analysis
The APsystems Energy Communication Unit (ECU) is installed by simply plugging it into any
wall outlet and providing an Ethernet or Wi-Fi connection to a broadband router or
modem.After installing and setting the ECU (see ECU manual), the full network of APsystems
Microinverters automatically reports to the APsystems Energy Monitor and analysis (EMA)
web server.The EMA software displays performance trends, informs you of abnormal events,
and controls system shutdown when it is needed. (See ECU manual for instructions.)
