Good day all ,
Reading all the problems with frequency shift ... that it is too slow ... yes it is already for years.
Victron ... please make it faster and take out the time when it is high to nominal ... or in other words , put an assistant there so we can control the frequency shift accordingly if needed , also called PID!!
As can be read from all the problems (more than 1300) ... this is the main one to be slow ... yes ... that worked 10 years ago ... but now with new transformer less inverters that´s not needed anymore and recently the Ohm-pilot from Fronius especially.
I have checked the Fronius site , there they regulate on power only .... but also there the frequency still goes up since the Victrons are too slow ... check with Fronius!!
To give you an example ... I have 8 KWp panels on the outputs of the Quattro´s , I regulate my excess energy as soon as the frequency is 50.05-50.10Hz to my warm water heating with the help of a PID controller and 7500W single phase Triac cards.
This PID controller is so fast and acurate!! ...very good ... but your Quattro´s takes so much time to come back from high frequency to nominal ... that my battery has to supply energy! not good.
So .. please make an assistant PID for this frequency shift ... or make it very fast as it should be!!
With the best regards , Jeroen , Marine Engineer.
