4.Installation Preparation
2. Ensure that protective end caps are installed on all unused AC connectors. Unused AC harness
connectors are energised when the system is powered up.
3. AU-1P300/350/4002G supports up to maximum 11 units branch. AU-1P6002G supports up to
maximum 6 units branch. AU-1P8002G supports up to maximum 5 units branch. AU-1P10002G
supports up to maximum 3 units branch. AU -1P1600/20002G supports up to maximum 2units branch.
4.4 Precautions
The equipment is installed based on the system design and the location .
The installation must be done with the equipment disconnected from the grid (power disconnect
•
switch open) and with the PV modules shaded or isolated.
Make sure the environmental conditions of the microinverter's requirement (degree of protection,tem
•
perature, humidity, altitude, etc.) as specifed in the Technical Data section.
Avoid direct sunlight to prevent power derating which can be caused by an increase in the internal
•
temperature of the micro inverter.
Keep the inverter in well-ventilated place to avoid over heating.
•
Keep the inverter away from gases or fammable substances.
•
Avoid electromagnetic interference because it can compromise the normal operation of electronic
•
equipment.
Installation location shall meet the following conditions:
Install only on structures specifcally designed for PV modules (supplied by installation technicians).
•
•
Install microinverter underneath PV modules to make sure it works in the shadow. Nonobservance
may cause the derating of inverter production.
