Recommendations to replace BlueSky 2000 MPPT

Many auto charging systems use remote sensing for a good reason. Any electronics should never be mounted in the same compartment as flooded batteries unless the compartment is a bay on a large RV. CR spend winters in Mexico. Warm and humid. Corrosion is more pervasive. I had to mount my controller16' from the batteries. Unless I wanted it to take a bath everytime I drive in the rain. Smear dielectric grease all over the thermistor mounted on the battery. I am going to follow this thread with interest as I too shpuld be seeking a good MPPT controller.

What makes you think that? How does a remote battery voltage sensor make up for voltage drop due to inadequate wire size on the controller to batteries run?

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.

+1 for Morningstar Tristar MPPT. However I think 30 amp is plenty unless you plan to add more panels.

Hi,

I would consider the Tristar MPPT 60 amp unit.

I've investigated almost every option. There is NO room in the battery compartment and little enough in the bay next to it which is located UNDER a slide. Beside which, the BlueSky is a bulkhead (set into a hollow wall) and would need make mounting brackets but even then it would not be easy to get at in order to see what it was doing or to make any adjustments. (The electrical bay is under the slide.)

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.

Also, I have been tempted for several years to add more solar panels and the BlueSkye is maxed out with the 420 Watts that I have already.

Why perpetuate the problem? Get the controller close to the batteries. Get creative or live with a bad configuration.
