When all the cables were refitted after buying the new mppt, i cut the cables as normal. I don't have a ferrule thingy so screwd the cables in as many do.
They where working fine until the 3rd panel was installed, which is another 8.3 amps on top of the 16.6 from the other two. so never gave it a through, is was only after the blue bolt scandal that i thought there's a problem. I remember someone saying about cable temperatures so did a touch test on the roofs ones and they seemed ok. orobustly the air is cooling the cables.
same cables as you can see is on a warm side with a smell of rubber. the cables are sort of accessible. was looking at the cables today again. they get warmer as they get closer to the mppt.
I give the guys a call at 12 v planet and see how long these cables will take otherwise, i will disconnect one panel to cut the power down a bit.
i,m checking the cables in the mppt again soon when the sun clears off so i don't want t turn blue hahaha
That's scary but then again I can kill a packet of baskets without a care in the world lol.
The cable temptutres could be normal maybe as power is flowing all day, say 6 hours at 15 amps but as you say the cables are 20 amp 4mm ones.
I can't wait to find out.
Ok long shot. I bought new cables from the mpppt to the batteries, 6 mm ones, 12 volt planet said they ok for the 15 feet length. could it be that the cables are the wrong size and the mppt can't get the power out fast enough causes a traffic jam of power to back up in the cables?
I did hear moaning inside the cables so i guess the power is fed up in the jam lol.
another problem could be a miss reading MT50 display where it states 15 amps but it could be more, is this possible? I have no multimeter to test all the panels together. mine only goes to 10 amps and blown it up once already.
