4.2.1 Environment Requirements
• The installation environment must be free of inflammable or explosive materials.
• The location should be not accessible to children.
• The ambient temperature and relative humidity must meet the following requirements.
• Please consult SUNGROW before installing inverters outdoors in salt stress areas. Salt
stress areas mainly refer to coastal areas that are within 500 meters from the coast. The
deposition of salt fog varies largely with nearby seawater characteristics, sea wind, pre-
cipitation, relative humidity, terrain, and forest coverage.
• Inverters free from direct sunlight, direct rain and snow have longer service life. Consider
sheltered places as the installation location.
• 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.
• The inverter is installed more than 30 m away from third-party wireless communication
facilities and living environment.
4.2.2 Carrier Requirements
The mounting structure where the inverter is installed must comply with local/national stand-
ards 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.).
