Ferroamps SSO:s can be placed freely where it is easiest from a space and installation perspective. A SSO has an IP65 enclosure and can advantageously be placed outdoors and close to the solar panels because it provides good cooling and in the event of a shutdown of the system, the cables between SSO and EnergyHub will be de-energized. Placement in direct sunlight should, however, be avoided.
Each SSO single 8kW contributes with a heat load up to about 60 W at full solar production so they should be placed where they can get some air circulation and not in a small enclosed space.
See also the installation manual for the installed model of SSO.
