I already have running here at the farm a Fronius 6kWh grid-tied system. I purchased 20 panels from SanTan Solar as mentioned in Will's video https://store.santansolar.com/product... I wish to use all 20. Here is a detailed photo from the back of that panel.
I purchased a Growatt SPF 6000 DVM split-phase 48V6kW. Here's the info from the side of it:
And lastly, I purchased a Bigbattery KONG 48V LiFePO4 12kWh 233Ah.
Now the maths start. You see I can not exceed 150V input from the PV and each panel puts out 30.6V @PMAX and 368.2V at open circuit.
So I have PV Y connectors and Tri connectors and of course can buy others like the MC4 T Branches. But alas how to reach the MAX wattage without exceeding the MAX 150V. Then how to use all 20 panels.
I'm open for input as I continue I will share photos and comments, experiences, and gripes.
