2. APsystems Microinverter 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 produced 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 case is designed for
outdoor installation and complies with the IP67 environmental enclosure rating.
Simple to install
You can install individual PV modules in any combination of module quantity,orientation, type,
and power rate.
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 configurating the ECU, 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.)
