I have a microgrid system with quattro and fronius PV Inverter and no grid.
Works fine
Planning to install gasolin genset as a backup if runs out of battery .
Is there some restictions ?
Does the Quattro disconnect genset to prevent feeding backwards (for example)
I mean that quattro cant controll phaseshifting in situation of a petrol genset
it can still control phase shifting on the smaller generators, as long as its not huge that is
what will happen if it did feed back then the gen would over rev and thus frequency would go up anyway, (well that maybe different if its a inverter gen)
if you are still concerned then maybe connect the grid tie to AC2 out then use a assistant to turn ac2 on all the time and turn it off it the DC volts goes above say 58V or what ever you want the cutoff to be
