I currently have the Tracer4215BN controller which can handle 520W at 12V.
I currently have 520W solar, but space for another panel, so I'm considering adding one, meaning I will need to upgrade my controller to handle the 740W total.

MPPT is a given, size matters as I have limited space in a cupboard, and Blutooth is just a nice to have.

Who has a 750W controller, or more, and how do you rate it?

Cheers

I have an SRNE ML4860 new in box if you're looking for one. Bought it 3 years ago when I bought my two ML2430's - was going to have a play around with solar on the shed at home but never got around to it.

Just purchase another Tracer solar controller and run them in parallel. I have two tracers 40 amp units controlling two separate sets of solar, 350 watts and 400 watts, and they work well together.

I have 2 solar controllers. The controllers that take really big amps were too big at the time (5 yrs ago). I have seen high amp controllers that are quite small now (Victron, if i remember right). Space might decide adding another vs new and more amps.

I have a 100 amp Tracer AN. I think that I would get more output from my setup if I split the panels between two controllers but like you space will not allow. Can't fault the unit so far. You can plug in options for BT, W Lan and wired remote readout at reasonable prices. I purchased direct from EP Ever off their web site, very easy to deal with
