Congrats on the new system, with 15.6kW of panels you will likely have a bigger inverter than 3.8kW or multiple inverters
The pw+ implied three integrated 7.6kw inverter on top, 7.6 can only handle 10.6kw of panel, do the 3.8 was added to handle the other 5kw or so.
Ah, that is a useful number to know, since I'm considering an 8.77kW solar roof and was wondering if it was a problem that 8.77 > 7.6. How does one calculate the 10.6kW number from the datasheet?
The inverter spec sheet list the max DC/AC ratio as 1.4, do 7.6x1.4=10.64kw, know that this is the max, not the recommended, 1.2ish is typically the recommended Max for south facing roof or you are likely to lose more from peak clipping then from off peak generation generation gain Mine is east west so that's why I can go up to the 1.4
Aha, thanks, I missed that spec. My 8.77kW system would be 1.15, and this is for a combination of 3 south faces and one west face, so that should be easily accommodated.
The above would be true if inverters were free. As they cost money, going up to 1.4 on south facing roofs is often the economical choice.
