Hello,
I am new here.
I plan to order and have wired in series 3 x 240w (48-Cell) Jinko JKM240M-48 Panels rated at:
26.1V (Vmp)
9.20A (Imp)
32.1V (Voc)
Its a Portable setup and thus it will not be hard wired to my roof.
I will run 50ft of 10AWG cabeling from my Panels to my Charge controller. I expect a voltage drop loss of +-1.46%
I will wire these panels to a Victron 100v/50A Mppt Solar Controller - https://www.victronenergy.com/upload...-100-50-EN.pdf
The questions I have are as follows:
- Will my Solar Controller be able accept this array ?
- I did the following maths below (based on all three in series @STC) is it correct?:
32.1v x 3 = 96.3v - Based on this, am I safe to say that the voltage will not exceed my controllers limit here?
26.1v x 3 = 78,3v
78.3v - 1.46% = 77.16v - This is the voltage that will run down my 50ft run of 10AWG cabling and into my Charge Controller less the 1.46% loss.
77.16v/13.6v (Absorption rate suitable for my battery bank) = 5.673 - This is the ratio I will need to multiply the Imp of my array which is 9.20A.
9.20*5.673 = 52.19A - this is the Amperage my Solar Controller would theoretically output into my battery, however the solar controller can only put out 50A total.
- If my charge controller is only 98% efficient does this mean that total amps to my battery should be 52.19A - 3% = 50.62A?
- My battery bank is 2 x 12v 100AH AGM deep cycles connected in Parallel (200AH Capacity). Do I have too much panel for my relative to my Battery bank? I will boondock in my Camper for weeks at a time.
Thank you,
Michael
