How well will an EpEver Tracer MPPT C.C. charge a 24v Bank with a single "20v" 60 Cell panel?
A while ago I bought the Tracer 4210A 40 amp MPPT to upfit my van. At the time, all I planned on using was a 12v bank. Another Florida summer later, I decided to add an small AC unit to the van and I think going 24v would be a better fit. This also allows me to run smaller power cables under the door's weather strip. I got a great deal on a 310W 60 cell Silfab SLA-M from my local solar company. The van is not long enough to fit a 72 cell on the roof.
Depending on the controller, they say 60 cell panels (Voc<38v) either can't charge 24v batteries efficiently or even at all. My panel has a Voc of 40.25v which seems to be entering 72 cell/ 24v range. The local solar company also has a 60 cell Solaria PowerXT 355W with a Voc of 47.7v if I need to exchange it. The Tracer manual does not mention anything about this specific use-case. Just "Best", "Max" but no "Min". There's a video on Youtube showing a Midnite Solar MPPT charge controller charging a 24v battery with a 60 cell with much less efficiency. Would I be going a step backwards ordering a 24v inverter? Should I wire the batteries in parallel and keep everything 12v? Thank you.
