Pecron Update, Still Needs Higher PV Voltage. 

Well, it seems the Pecron E600LFP still needs a higher voltage to trigger the MPPT charge controller. The "12v to 18v" 5521 port is a lie, you need a minimum of 18v with 20v to 24v being a better option. 12v won't even trigger the charge controller. Only solution, order a 32+volt panel and use the 5 pin aviation input.
