Sungrow SG125CX-P2 User Manual

User Manual 4 Mechanical Mounting
• Do not install the inverter outdoors in areas with high salinity, which mainly refer to the ar
eas within 500 m away from the coast. The deposition of salt fog varies largely with near
by seawater characteristics, sea wind, precipitation, relative humidity, terrain, and forest
coverage.
• Install the inverter in a sheltered area to avoid direct sunlight and bad weather (e.g. snow,
rain, lightning, etc.). The inverter will derate in high temperature environments for protec
tion. If the inverter is installed in direct sunlight, it may cause power reduction as the tem
perature rises.
• The inverter should be well ventilated. Ensure air circulation.
• The inverter generates noise during operation and is not recommended to be installed in
living areas.
4.2.2 Carrier Requirements
The mounting structure where the inverter is installed must comply with local/national stan
dards and guidelines. Ensure that the installation surface is solid enough to bear four times
the weight of the inverter and is suitable for the dimensions of the inverter (e.g. cement walls,
plasterboard walls, etc.).
4.2.3 Angle Requirements
Install the inverter vertically or at the maximum allowable rear tilt angle. Do not install the
inverter horizontally, forward, excessively backward, sideways, or upside down.
Inverters in floating plants cannot be installed at a back tilt.
