USER MANUAL
For proper inverter operation and full performance
delivery some mounting guidelines must be observed.
Although micro inverter does not need any forced
ventilation and is cooled by natural heat exchange
with surrounding air, it still need some air around its
aluminum enclosure to cool efficiently.
We strongly suggest to place micro inverter at least
15mm bellow the panel surface and to leave at least
20mm between inverter and underneath surface to
avoid panel heating and micro inverter overheating.
Micro inverter can be positioned above or below
supporting Al frame, as indicated on drawings
bellow. Placing micro inverter on bottom side of Al
support, decrease heat transfer from micro inverter
to solar panel, increasing efficiency on high ambient
temperatures.
Mount micro inverter in locations, which are out of
direct sunlight.
We do not recommend mounting micro inverter directly
between panel and roof surface since air irculation is not
guaranteed. Efficiency of the system will be decreased
and the micro inverter and the panel can be overheated
if mounted like shown on bellow drawing.
If micro inverters are mounted as showed above,
warranty period is voided.
