What is the total solar power in a 3 phase system with 3 x 48/5000/70 fed by a Fronius Symo 15kw PV inverte being fed by 18kw of solar panels. I need to get my PV solar inverter support assistant set correctly. Thanks for any help anyone can provide...
Should the figure be 4000w, 15000w or 18000w For Total Solar power in PV inverter support assistant? Does anyone know?
you use the total power, and both figures:
So based on the information of my system 15000 and 18000 are the figures that I would use?
Hi, I have done exactly what has been advised. I updated the firmware & set the PV inverter support assistant as advised but the system is ramping down at to 10500w & won't go above. Do you have any suggestions that may fix it. The system will ramp down Fronius to 10500 even while batteries are at 60% & the house is using 3000w so the charge going into the batteries is reduced instead of Fronius being ramped up to compensate. I just can't get the system to use all the solar I have. When I fire up the generator, the system will use 10kw continuously to charge the batteries then ramps the generator up to meet the house demand. I have as much solar power as I have generator power but the system just won't use the solar. What settings could be wrong to cause this major inefficiency? Thanks for any help you could provide.
Can you try playing around with the settings a bit?
I suspect it has to do with maximum charge current while the system is inverting, but I'm not sure.
