Quattro 15kv, Fronius Primo 8.2 with 7900w PV, 3 x Kilowatt labs 3.55kw modules, 2300w PV running thru a 150/70 Victron charge controller, Off Grid MG50
Maximum charge voltage of the modules are 54v and if they are fully charged and the AC PV is supplying 4000w with 4000w Quattro loads and the loads drop off, The system is way too slow to react in shifting the HZ to throttle the AC PV. (3 to 5 min)
I had to reduce the max charge voltage of the modules via the Quattro to 53v to allow a full volt of slow down time. Seems to be working at the moment.
Is there any way to increase the speed the Quattro ramps up the HZ to throttle the Fronius?
(I’m using the standard settings in the VE configure assistant to control the Fronius)
Should I Adjust Victron HZ shift values in the inverter to suit the Fronius values?
What are the correct Fronius Primo 8.2 inverter HZ shift values ?
