If connecting more modules than Power Optimiser inputs in parallel, use a branch
cable. Some commercial Power Optimiser models have a dual input.
Position the Power Optimiser close enough to its module so that their cables can be
connected.
Make sure to use Power Optimisers that have the required output and input
conductor length.
Completely shaded modules may cause their Power Optimisers to temporarily shut
down. This will not affect the performance of the other Power Optimisers in the
string, as long as the minimum number of unshaded Power Optimisers connected in
a string of modules is met. If under typical conditions fewer than the minimum
Power Optimisers are connected to unshaded modules, add more Power Optimisers
to the string.
To allow for heat dissipation, maintain clearance as specified below.

When installing PV modules in a confined space such as Building-integrated
photovoltaic (BIPV) modules, ventilation measures may be required to ensure that
the Power Optimisers are not exceeding the maximum temperatures stated in their
specifications.
