Installation Precautions

Note: The device must be installed according to the following system design requirements

Installation of Microinverter：

• Ensure the mechanical compatibility of the microinverter DC connector with its connected PV module connector.
• Installing a microinverter without ensuring that the module connector is compatible with the microinverter DC connector is unsafe and can cause functional problems such as a ground failure that can shut down the microinverters. When installing, disconnect the device from the power grid (disconnect the isolation switch), and shield or isolate the photovoltaic
• Ensure that the mounting surface or structure can support the weight of the microinverter and bracket, and ensure that its width exceeds the bracket width.
• Install the microinverter using the existing holes, do not drill any additional holes in the inverter.
• Drilling holes in the frame of a microinverter may void the warranty. Consult the microinverter manufacturer before drilling holes.
• A hole in the frame of a microinverter may reduce its structural strength or cause damage to it, and the specific location of the hole needs to be evaluated and confirmed by the manufacturers.
• Do not use a percussion drill to install a microinverter. Drilling vibration may damage the micro inverter and void the warranty.
• Use a torque wrench or a drill with an adjustable clutch that meets mounting torque requirements.

AC Accessories Installation：

• Refer to the Technical Specification to ensure that the environmental conditions fit the requirements of the microinverter (degree of protection, temperature, humidity, altitude, etc.)
• Installation of the microinverters is carried out based on the system design provided by installers
• To avoid overheating, always make sure that the air flow around the microinverter is not blocked.
• Do not install in places where gases or flammable substances may be present and avoid electromagnetic interferenc e that can compromise the correct operation of electronic equipment 。
• To avoid muscle strains or back injuries, use the appropriate lifting equipment to deliver the microinverters, and use lifting AIDS when needed.
