9.1.2 Checking the Fans
1. Request installer password from the SMA Serviceline (contact see page 92).
2. Set parameters "CoolSys.FanTst" and / or "Fan test" to "On" in installer mode.
3. Check the air-flow of the fan.
The inverter takes in air at the bottom and it comes out again at the top. Listen for any unusual
noise that could indicate incorrect installation or that the fan is faulty.
4. Set parameters "CoolSys.FanTst" and / or "Fan test" to "Off" again.
☑ The fan test has been completed.
Checking the Fan
To test the fans you will need a special data logging device (e.g. Sunny WebBox) or a PC
with appropriate software (e.g. Sunny Explorer) in order to change the parameters of the
inverter.
You will also require the installer password to access installer mode.
