The two panel strings need to keep as balanced as possible Eg: 21 Panels (10+11) The fan noise is related to the load. At 5000W the inverter is fully loaded and that creates heat which is dissipated from the internal heat sink which is assisted by a very small fan drawing outside air and directing across the heat sink and then out of the top of the unit. If the garage door is in direct sun the garage ambient temperature will be higher and the inverter will be hotter. If the inverter get overheated it will down rate its output. You will also need to occasionally clean the dust from the fan blades as this causes noise and load on the little fan and the fan will last longer. Australian legislations allows the installer company to overload the inverters by 33% Eg: 5000W+33%= 6600W. This allows the inverter to have more panels collecting sunlight in overcast / cloudy days to allow the inverter to actually make more power than it would with just 5000W of panels.
Thank you for the detailed comment. I've spoken to a lot of installers and solar users. As good as Fronius brand is their inverters are way too noisy. Looks like other brands caught up and doing even better job.
You can’t have 2 panels facing east because the inverter needs a minimum voltage input - I believe the fronius primo is 240VDC. Each panel generates roughly at 50V, so you will need at least 5 strung together. If you have 330W panels you will have 20. I have 13 north and 7 west. 6.6kW of panels that they sell you is a waste on north face as inverter can only output 5kW. So 1.6kW wasted when sun beaming down midday. Even though we have 4.3kW north and 2.3kW west, even between 11-3pm the inverter is maxed out at 5kW. Can see the flat line on the solar live app
Is not waste at all ! Will be limited production on a peak hour but outside the peak normal more panls will produce more energy ! In fact if with a sistem of 5 KW panels you ll heve 2-3 hours peak with 6,6 KW you ll have another 2 hours peak and in all other part of the day will produce more with 6,6 than 5 kw ! In fact you lose 1,6 KW just for peak hours , and the same the inverter will start sooner in the morning and stop later in the evening ! U can use maximum 50% more power panels than actual Inverter you have. The name is : supracharged system !

@@GregYurchenko This is a big reason I got SMA Sunny boy 2.5 instead as it has no fans at all - silence is golden as the inverter is in my house.
@@MrButuz indeed, as good as Fronius is the noise was totally unbearable. Good move choosing silent inverter!

1 string 8 panels facing east

Is the Froniuus unit a string inverter?
Yes
Please advise how to find V.code while connecting wifi thanks
Sorry, I sold the house and don't have an access to the unit anymore. But WiFi settings from my memory are very prominent in the menu
