11.16 External Cooling Fan Attachments
The use of an external cooling attachment for FRN0032G2S-2G/FRN0018G2□-4G to FRN0115G2S-2G/
FRN0060G2□-4G inverters allows cooling fins to be directed outside the panel. This enhances cooling efficiency,
and allows the panel size to be reduced. It can release from the panel approximately 70% of the inverter’s generated
loss.
Installation with external cooling is possible for units of FRN0146G2S-2G/FRN0075G2□-4G or higher by moving
the mounting base.
