Ø Make sure that the inverter is installed in a suitable place and is not allowed to be installed in a closed box; fig5.2 Mounting dimensions for an inverter fig5.4 Closed box Ø In order to reduce the inverter load and extend the life of the inverter due to direct sunlight, we recommend installing a awning.
Inverter Wiring 6 Secure the wall mount as shown, do not let the screws flush with the wall, instead expose 6.1 Safety 2 to 4 mm. A high voltage in the conductive part of the inverter may cause an electric shock. Therefore, when performing any installation work on the inverter, make sure that the AC and DC sides of the inverter Danger are powered off.

6.3 DC side wiring The MID series inverter has two independent inputs, as shown below: Ø When the sun shines on the panel, voltage will be generated. The high voltage after the connection may cause life-threatening. Therefore, before connecting the DC input line, the panel should be shielded with opaque material before operation, and the inverter is ensured.
