the minimum optimizers are connected to unshaded modules, add more
optimizers to the string.
To allow for heat dissipation, maintain a 2.5 cm / 1" clearance distance between
the power optimizer and other surfaces, on all sides except the mounting
bracket side.
When installing modules in a confined space, for example, if installing Building-
integrated photovoltaic (BIPV) modules, ventilation measures may be needed to
ensure the power optimizers are not be exposed to temperatures outside their
specifications.
