Unless you have some shading issues where the panels are located Yes, series wire.
When you say MPPT that brings up the question, Is your controller a true MPPT controller? There's a lot of bogus Chinese controllers that even have MPPT on the face of the controller.
Here's an example of a fake.
If you can live with MSW you will be pleased with the Trace.
Mine has performed flawlessly for 24 seasons.
myron said:How do I check they 60 cells? They mark 24 volts though
Count them. They would be 6 across and 10 high. People who don't know much about solar sell solar equipment all the time. A 24 volt panel would be 72 cells with a Vmp. of around 36 volts and an Voc. of around 45 volts. 60 cell panels are lower voltage, insufficient for fully charging a 24 volt battery1
I'm willing to wager real dollars that this isn't a real MPPT controller. I see nothing in the info to convince me. I once bought a very similar controller doubting it's capability. I was right. Connected a 175 watt 24 volt, 5ish amp panel to it and a 12 volt battery, hoping to get 10 or so amps. Guess what, amps in = amps out, NO MPPT.
Here's the one I knew was fake
Maybe a dumb question, but I have to ask. Are the solar panels actually in the sun? While you can get some voltage from panels even indoors under artificial light you will get no appreciable current. Are they oriented correctly and in full sun? The rated amperage should only be expected in full sun and will be substantially less with poor orientation. Are the panels a long distance from the panels, and if so what gauge wire are you using?2
