Three-phase Microinverter HMT-1600/1800/2000-4T
Note: The voltage of modules (considering the eect of local temperature) must not exceed the maximum input
voltage of the microinverter. Otherwise, the microinverter may be damaged (refer to the Technical Data section to
determine the absolute maximum input voltage).
Installation Preparation
A PV module
B DC extension cable
C Microinverter
4. Installation Preparation
4.1 Position and Space Required
Please install the microinverter and all DC connections under the PV module to avoid direct sunlight, rain
exposure, snow buildup, UV etc. The silver side of the microinverter should be up and facing the PV module.
Leave a minimum of 2 cm of space around the microinverter enclosure to ensure ventilation and heat dissi-
pation.
Note: In some countries, DTU will be required to meet local grid regulations (e.g. G98/99 for UK etc.)
4.2 Connecting Multiple PV Modules to Microinverter
General Guidelines:
1. PV modules should be connected to DC input ports of a microinverter.
2. Use DC extension cable when the original cable is not long enough. Please consult the local power opera-
tor to make sure that the DC cable complies with local regulations.
Two typical wiring methods are shown below.
