It will only work if you are charging a 24v system. Check out the mppt tool here:

@Eduardo Kang @LyonGalea, it's worth noting that the MPPT is current-limiting on both the input and output sides, so it's not that the 75/15 won't work with this panel, it's just that it'd be kind of a waste because your panel can potentially generate twice as much power as the 75/15 can put out. Most people will want to harvest as much as they possibly can, thus why I recommend the 100/30.

@LyonGalea. The amperage from that panel is too high at 12v for the 75/15. The 75/15 is limited to 15a, at 12v that panel would generate a maximum around 27a. If you need to charge a 12v system, follow @Justin Cook advice and go with the 100/30.


Good luck!

@LyonGalea, to ensure you're capturing your full potential harvest from one of these panels you'll want a 100/30.
