Determining the Installation Position

Determining the Installation Position

Installation Environment Requirements

  • The solar inverter can be installed indoors or outdoors.
  • Do not install the solar inverter near flammable or explosive materials.
  • Do not install the solar inverter where its enclosure and heat sink are easily accessible, because the voltage is high and these parts are hot during operation.
  • Install the solar inverter in a well-ventilated environment for heat dissipation
  • When the solar inverter is installed under direct sunlight, the power may be derated due to the temperature rise. You are advised to install the solar inverter in a sheltered place or install an awning over it.
  • The SUN2000-125KTL-M0 should be physically separated from third-party wireless communication facilities and residential environments by distance greater than 30 m.
Figure 4-1 Installation environment

Mounting Structure Requirements

  • The mounting structure where the solar inverter is installed must be fire resistant. Do not install the solar inverter on flammable building materials.
  • Ensure that the installation surface is solid enough to bear the solar inverter.
  • In residential areas, do not install the solar inverter on drywalls or walls made of similar materials with a weak sound insulation performance because the noise generated by the solar inverter may interfere with residents.
Figure 4-2 Mounting structure

Installation Angle Requirements

The solar inverter can be support-mounted or wall-mounted. The installation angle requirements are as follows:

  • Install the solar inverter vertically or at a maximum back tilt of 75 degrees to facilitate heat dissipation.
  • Do not install the solar inverter at forward tilted, excessive back tilted, side tilted, horizontal, or upside down positions.
Figure 4-3 Angle

Installation Dimensions Requirements

Reserve enough space around the solar inverter for installation and heat dissipation.

Figure 4-4 Installation dimensions

For ease of installing the solar inverter on the mounting bracket, connecting cables to the bottom of the solar inverter, and maintaining the solar inverter in future, it is recommended that the bottom clearance be between 600 mm and 730 mm. If you have any question about the clearance, consult the local technical support engineers.

When installing multiple solar inverters, install them in horizontal mode if sufficient space is available and install them in triangle mode if no sufficient space is available. Stacked installation is not recommended.
