Solar charge controller selection help needed

The included monitor does not have to be connected in between any thing. It is connected to the controller and probably, a shunt on the 12 V (-), immediately before frame ground. You will not lose any functionality by not using the "Load" outputs.

How all of this relates to the rating of your existing converter is still baffling. Where does 55 amps and a conflict raise itself? Your solar panel is not rated to deliver 55 amps. The controller will not produce 55 amps. If you have a solar system that does deliver 55 amps, it has nothing to do with the converter. In fact, both could be operated in parallel in most cases.

Good luck with the installation. Fire way with any questions, I think you may have a couple.:B

I got the connection sequence but how can you monitor DC load power consumption if it is not running "through" the controller? I suspect that if I connect it the way you suggest, I will lose LVD because the controller will not be able to shut off the load.

As best I can understand now, I connect the the controller as follows:

Battery goes to Controller Battery

DC panel goes to Controller Load

Panels go to Controller in

And finally, the converter is direct connect to battery.

The amperage worry comes in if I need to run 40 AMPS through it. The point is kind of moot because even the 40 AMP EP Solar Tracer 4215BN has a 20 amp load limit.

In theory this is plenty but the 30 AMP 3215BN model has the same load rating.

Is there any chance we could chat on the phone? PM me if that works for you. I am really confused, as you can probably tell!
