2.APsystems Microinverter System Introducon

2.1 Key elements of an APsystems system

The APsystems Microinverter is used in ulity-interacve grid-ed applicaons, comprised of three key elements:

 APsystems Microinverter

 APsystems Energy Communicaon Unit (ECU)

2.APsystems Microinverter System Introducon

2.2 The advantages of an APsystems system

This integrated system maximizes solar energy harvest, improves safety, increases system reliability, and simplies

solar system design, installaon, maintenance, and management.

APsystems Microinverters maximize PV energy producon

Each PV module has an individual Maximum Peak Power Tracking (MPPT) control, which ensures that the maximum

power is produced to the ulity grid regardless of the performance of the other PV modules in the array. When PV

modules in the array are aected by shade, dust, dierent orientaon, or any situaon in which one module

underperforms compared to the other ones, the APsystems Microinverter ensures top performance from the array

by maximizing the performance of each module individually within the array.

Safety with APsystems Microinverters

In a typical string inverter installaon, PV modules are connected in series. The voltage adds-up to reach high

voltage value (from 600 Vdc up to 1000 Vdc) at the end of the PV string. This extreme high DC voltage brings a

risk of electrical shocks or electrical arcs which could cause re.

When using an APsystems microinverter, PV modules are connected in parallel. Voltage at the back of each PV

module never exceeds PV modules Voc, which is lower than 60 Vdc for most of PV modules used with APsystems

microinverters. This low voltage is considered “safe to touch” by remen department and will avoid risk of

electrical shock, electrical arcs and re hazards.

More reliable than centralized or string inverters

The distributed APsystems Microinverter system ensures that no single point of failure exists across the PV system.

APsystems Microinverters are designed to operate at full power at ambient outdoor temperatures of up to 65 deg

C (or 149 F). The inverter case is designed for outdoor installaon and complies with the IP67 environmental

enclosure rang.

Simple to install

APsystems Microinverters are compable with most of 60 and 72 cell PV modules or 120 and 144 half-cut cells PV

modules. (In order to conrm compability of PV module with APsystems microinverter, feel free to check our

online “E-decider” module compability tool or contact your local APsystems Technical Support).

Installaon requires a minimum number of accessories and microinverters oer a lot of versality to the installer:

microinverters can indeed be installed on different roofs with different orientaon or with modules having

dierent orientaon.

In the same way, end-user can extend their system whenever they want with microinverters.

Smart system performance monitoring and analysis

The APsystems Energy Communicaon Unit (ECU) is installed by simply plugging it into any wall outlet and

providing an Ethernet or Wi-Fi connecon to a broadband router or modem. After installing and setng the ECU

(see ECU Instrucon Manual), the full network of APsystems Microinverters automacally reports to the APsystems

Energy Monitor and Analysis (EMA) web server.
