Important Safety Instructions
Radio Interference Statement
CE EMC Compliance
：
The equipment can comply with CE EMC, which
are designed to protect against harmful interference in a residential
installation. The equipment could radiate radio frequency energy and this
might cause harmful interference to radio communications if not following
the instructions when installing and using the equipment. But there is no
guarantee that 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:
A) Relocate the receiving antenna and keep it well away from the
equipment.
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.
