Ensuring Maximum Inverter Performance with Active Cooling

The actual installation for actively cooled inverters is also much more flexible, as the inverters draw cool air in from the side, and dissipate the heated air upwards. This means that inverters with active cooling technology can be installed horizontally, vertically, and even flat; inverters with passive cooling, however, can only be mounted at a 90-degree vertical angle.
