1. Introduction
The APsystems Energy Communication Unit (ECU-B) is the information
gateway for our inverters.ECU-B has been specially developed to monitor
small PV systems up to 4 PV modules.The unit collects module performance
data from each individual inverter and transfers this information to an
Internet database in real time, requiring only a single data and power cable.
Through the APsystems Energy Monitoring and Analysis software, the
ECU-B gives you precise analysis of each inverter and module in your solar
installation from APP. The user-friendly interface lets you access your solar
array in seconds.
Features
Collects individual PV module and microinverter statistics
Communicates in real time
Requires no additional wiring
The APsystems ECU-B is used in utility-interactive grid-tied applications,
typically consisting of five key elements:
APsystems microinverter(s)
APsystems Energy Communication Unit (ECU-B)
EMA Manager APP: for installer to set-up the ECU-B
EMA APP: to enable end-users to have access to the data and
performance of their system anytime, anywhere
APsystems Energy Monitoring and Analysis (EMA): web-based
monitoring and analysis system, for both end-users and installers
