HI You could try this ( no warranty if you use it ) 
 SolarPower software wants one when changing major settings.
The password can be found in this manual hys-3000-ba-de-neu  on page 16, right after the word "Werkspasswort".
It is also posted here: infinisolar-3kw-plus-factory-password in the last post.
Werkspasswort "zAxE12_ObB8ya"

HI , there is a setting Generator as power.  I have never used it although it may give you more Frequency leeway on the power coming in but if you have a grid tie setting it may remove outgoing power to Generator which I think is a good thing , No of this is confirmed maybe if you try it you can report back and let us know it worked , 

Hi , Hernancalcagno 
and others that may have the 50.1 Hz issue with Infinisolar , The way I resolved it was after a deep dive into the setting I found that:
If you Enable Wide AC input range . it will open up the frequency range on incoming AC and the constant disconnecting and reconnecting when the grid frequency is not 50.9 Hz and below stops . And you dont need to void your warranty with a factory password.
I hope this resolves the 50.1 Hz issue , I found my system is stable for 5 months now since i changed that setting .
