That's why I got the Tracer with its 100Voc limit. I wanted to try my 12s in series and the Eco-W can't do that. As it happened the amps with series = amps in parallel so didn't need the Tracer.
I might have got more AH with series in low light, but you can't tell if you do. You don't have the comparable AH number for parallel. Wouldn't be anything worth the bother in our situation. Might be important in another scenario. Not my problem.
I use fat enough wire from panel to controller that I get no loss in amps with 12v PWM so that is extra good with 24v MPPT. Thin wire might be easier to deal with in some rigs, but not an issue in our set-up.
In our trailer, you can store the panels behind the sofa or just lay them on the bed for when on the road.
