Thanks in advance for your advice.
Looking for the best way to string these panels into one or more charge controllers. Batteries are 48v, golf cart right now. Nothing wired, just collecting parts and pieces.
Not gonna do the grid tie thing.
Yes, it is a mixed bag, but the price was right. What I would like in the main array.
6 - ASE 50W, Made in 2001. Vmp 17.2 Imp 2.9
4 - Evergreen 55W, m/n ec-55 (don't know date) Vmp 16.1 Imp 3.42
4 - Sun Electronics (Evergreen?) 180W, Made in 2006. Vmp 25.9 Imp 6.95
4 - Evergreen 200W, Made in 2009 Vmp18.1 Imp 11.05
Also have 2 - Solarex Millennia 43W, mfd date v98g17. Looking kinda bubbley on top and bottom of film, but still works. Have a C40, figured I'd use these to trickle charge various 12v bats.
2 - Siemens 48W, Model m75, still work, but cells have turned 80% "white". no plans for these.
Now from what info I have read, MPPT charge controllers don't like mixed panel arrays and pwm seems to handle it better. Found one MPPT that would take duel array inputs, Aurora, but that is for grid tie. Also have read that you can be with in 5% to 10% of Vmp or Imp and do fine. Don't claim to know a lot, but you've got to get your feet wet some where.
Current thinking now is to parallel the 180W (103.6v@27.8a) and 200W (72.4v@44.2a) into separate strings for higher voltage, but if I go MPPT, that's 2 charge controllers. If I series connect 2 panels each and parallel the rest of the smaller panels (83.8W@5.8a), does this need yet another charge controller?
Ok, let me have it!
