I may have found a solution. BougeRv makes a 6-1 branch connector and they use 8awg wire. I can easily snip off the MC4 connector and splice a 10ft 8awg wire to drop into the van and into the MPPT. Does anyone see any problems with this?

I am basing my build off of Wills DIY 400w 12v solar package W/ alternator charging. The problem is the charge controller has a max open circuit voltage of 25V so the panels have to be in parallel. The issue I'm having is that I've read MC4 connectors have a max current rating of 20A but the 4-1...

Thanks for the reply HKTKD I should be fine on both the volts (max input for the device is 25V) and Amps (max input for the device is 50A) If I did my math right on a Temperature Coefficient calculator my max volts should be around 23.86. Are you saying to ditch the two 50W panels because I...

Every 12v solar panel I have seen does not go up to 30-40V no matter the watts, are you thinking of 24v solar panels?

If I connected the 200w solar panels in series wouldn't I be fine? Renogy's 100W solar panels have a higher Voc and Vmc? Renogy 100w Voc 24.3 Vmp 20.4 My 200w Voc 21.8 Vmp 18.6 Maybe I'm missing something, I am new to this
