ECU-C Installation/User Manual

7.Remote ECU-C Management (EMA)

The ECU-C has been designed with remote connect functionality. You can

access this remote functionality through the APsystems Energy Monitoring
& Analysis (EMA) website, using your installer login credentials. Changes

made remotely through the EMA do not take effect until the ECU-C’s next
reporting cycle.

The ECU-C must first be installed with Internet connectivity.

The ECU-C remote functionality allows you to do the following:



Set Time Zones



Manage Inverter IDs

There are additional ECU-C functions available but the instructions are not

outlined in this document. If you need to access one of the following
features, please contact APsystems Technical Support:



Change system parameters



Turn the inverters ON and OFF



Reset GFDI



Reset Power Settings

This section of the documentation assumes you have a working

knowledge of the APsystems EMA.

1) Log onto your APsystems EMA account.

Your Customer List within the Installer Portal is displayed.

Select the customer’s ECU-C you want to manage and click on the

username in the "Customer Account" column.
