4.3 Installation Site Requirements
The PVS can be installed outdoors. Please meet the following requirements:
Take the dimensions and weight of the PVS into account when selecting the
installation location. The PVS should be installed as close to the PV modules
as possible for easier current confluence and lower cable costs.
The ambient temperature ranges from -40℃ to +60℃, and the relative
humidity from 0 to 95%. The PVS should be installed in a dry, well-ventilated,
and dust-proof place.
Never install the PVS in a place directly exposed to sunlight. Otherwise,
excessively high temperature will cause lower power yields or even shorten
the service life of the device.
In a large-scale power plant, the PVS should be vertically installed at the
shading area of the bracket of PV modules. Maintain enough clearances
around the PVS for better heat dissipation and ease of routine maintenance.
