Single-phase Microinverter HMS-350/400/450/500-1T-NA
Installation location shall meet the following conditions:
• 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 fit the microinverter’s requirement (degree of protection,
temperature, humidity, altitude, etc.) as specified 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 microinverter.
• Keep the inverter in well-ventilated place to avoid overheating.
•
Keep the inverter away from gases or flammable substances.
• Avoid electromagnetic interference because it can compromise the normal operation of electronic
equipment.
•
Install only on structures specifically 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.
4.5 Precautions
The equipment is installed based on the system design and the location of installation.
