interference will not occur in a particular installation. If this equipment causes harmful
interference to radio or television reception, the following measures might resolve the issues:

B) Consult the dealer or an experienced radio / TV technical for help.
Changes or modifications not expressly approved by the party responsible for compliance may
void the user’s authority to operate the equipment.
Communication Statement
The APsystems Energy Monitoring and Analysis (EMA) software analyzes and reports the
performance of each module from real-time data collected through the Energy Communication
Unit (ECU) gateway. The EMA promptly detects any performance issues in the array,
pinpointing the location and nature of the problem and providing precise guidance for
maintenance, all within a user-friendly graphic interface.Communication between inverters
and the ECU may be affected by signal “noise” from nearby electrical equipment, the distance
between inverters and the ECU, the number of inverters supported, and other factors, so
sometimes the ECU experiences loss of signal or data randomly, that is not a problem or a fault.
If the ECU does not communicate with the EMA database at all, contact APsystems support.
