Erin, have NO experience with any of that family of CCs.
Why do you need a small MPPT CC? Is it because you want to use 60-cell PVs?
The manual is very thin on this product. Only LEDs for indicators ... need to remove a jumper to EQ (IIRC), limited voltage settability (although default is not horrible), fixed Absorb time, Comm Port needs Optional adapter ...
BUT, it does include a Temp Sensor (RTS) And it not too expensive.
But, really, I know nothing of them. FWIW, Vic
