2.5.10 Fan Operation
For 1-3KW models, there is one multiple controlled DC fan which starts to work according to the
below logic.
For 4-6KW models, there is one multiple controlled DC fan and one AC fan. The DC fan will work in
the same way as the 1-3KW models, while the AC fan will work once there is AC output from the
inverter. When the inverter is in power saver mode, the AC fan will work from time to time in response
to the pulse sent by the inverter in power saver mode.
The Operation of the DC fan at the DC terminal side is controlled by the following logic:
