5.2 Installation Precaution

Please install the Microinverter and all DC connections under the PV module to avoiding direct sunlight,
rain exposure, snow layup, UV etc. Allow a minimum of 2 cm of space around the microinverter
enclosure to ensure ventilation and heat dissipation.
*Note: For some countries the DTU will be required to meet the local grid regulation (e.g. G98/99 for UK etc.)

5.3 Space Distance Required

If the microinverters are installed on a concrete roof or steel roof, the communication with the DTU
may be slightly affected. Under such installation conditions, it is better for the microinverters to be
installed 50cm above the roof. Otherwise, more DTUs may be required to ensure the communication
quality between the DTUs and the microinverters.

5.4 Preparation

Installation of the equipment is carried out based on the system design and the place in which the
equipment is installed.
