According to Growatt USA and Signature Solar I only have my 12 kw Growatt inverter running at about half capacity with my currant solar array. I have 24 - 260 watt panels running to my growatt inverter now 12 panels 3s4p on each pv string. I currently have it set up as 12 panels 3s4p on each pv string going into the inverter. which gives me 113.7 voc , 35.6 Isc and 3120 watts on each string. According to Growatt and Signature Solar I can go as high as 250 vdc 7000 watts on each string of this inverter. Not to exceed 120 charge amps combined on both strings. So now I want to put all 24 -260 panels on 1 pv string and I have purchased 30 used Q-cell 265 watt panels that I want to install on the other pv string on my inverter. 15 panels facing east and 15 panels facing west can you suggest what will be the best way to configure these panels for each string. I am currently running everything thru 2 Midnight solar 6 string combiner box's with 20 amp breakers on each string only using 4 strings in each box at this current setup.
Would this combination work ok
1st string Hyundai 260 watt panels.
24 panels 4s6p 6240 watts voc = 151.6 and Isc 53.4
2nd string Q-cell 265 watt panels.
30 panels 5s6p 7950 watts voc = 191.75 and Isc 55.08
1 string going into 1 midnight solar 6 string combiner box and 2nd string going thru the other 6 string Midnight solar combiner box.
I know the 7950 watts will be more than the 7000 watts max on each pv string input to the inverter but I'm thinking with 15 panels facing east on my shop 4x12 pitch roof and the other 15 facing west shouldn't ever produce the full 7950 watts its rated at.
What you guys and gals think, would this be the best way to configure these panels for my inverter. or is there a better setup for them.
By the way I just purchased these 31- 4 year old used 265 watt Q-Cell panels for 1000.00 cash local pickup couldn't pass that deal up for sure.
