Are you kidding me, surely that does not sound right. I think it's time I'll introduce you to a decent choke. Salvaged from an Aerosharp inverter you get at least that many turns but with 2.5 times (10mm sq) wire area. The existing coils are wired in parallel: Hello I just wondering if you have an image of the other side of the choke. Trying to work out how they are wired and then connected. I am about to make my second MPPT and I might see if I can use this style. I have rewired the core from the same choke and the choke is a pain to unwind. Thanks Andy
