I purchased one of the super-cheap deck-of-cards-sized blue MPPT last year and sent it right back - it was clear it could never handle the 30A it was supposedly rated for.
These just showed up on Amazon and I couldn’t resist checking one out: https://www.amazon.com/gp/aw/d/B07P7GQ3MF?psc=1&ref=ppx_pop_mob_b_asin_title
This is a much more solidly built unit, only rated for 15A (and max Voc of 100V), and when I peak inside it’s got two honking-big inductors so I’m hopeful it is an actual MPPT and not a PWM.
I’ve got a month to decide whether I’m keeping it or not do I’d appreciate any advice on things to test and/or look for.
An Epever Tracer 2210AN is certainly a safer/more reliable choice, but for less than half the price, I couldn’t resist at least checking out this Jasmint Power SPT: https://m.aliexpress.com/item/32890260446.html
Long-term reliability is obviously a risk that can’t be avoided, but in terms of these cheapo MPPTs being deficient, what are some of the things to test / look for?
