Recommendations to replace BlueSky 2000 MPPT
Getting closer to end my charging problems; (long cable run) Easiest is to replace the controller Need one with: Remote battery voltage sense Battery temp sense user defined and easily set ...

Jay;
It will allow the controller to keep the battery voltage up to to where it should be. For instance, now, if charging at near 20 Amps, the controller will think the batteries have reached 14.8 when they are in fact only at about 13.8. Therefore they never let the batteries get to full charge.
I have described my set up at length in previous posts but in a nutshell here it is again: There is about 6feet of #10 connecting to about 20 feet of #6 between the output of the controller and the batteries. The #6 is the original connection between the batteries and converter which is no longer there. This in on the passenger side of the rig under the stove. The batteries are on the driver side in a compartment under the bedroom slide. The electrical compartment is beside that, also under the slide. Replacing that #6 will be a real chore, and I would have to pay someone to do that. There is very little room in that electrical compartment.

Anything with a remote battery voltage sense would take care of the problem with little if any loss of charging efficiency over one placed next to the batteries.
The Blue Sky SB3024iL with a IPN-ProRemote will allow placing the controller closer to the batteries and have remote control and monitoring.
For a PWM solution perhaps the Bogart SC2030 and TM2030.
