MT50 remote setup questions, need assistance.

I bought this kit

https://www.solarwholesaler.ca/produ...ppt-solar-kit/

I installed it. I have a couple questions about the settings. I have two 12V batteries in parallel (yes I know 2 x 6V are even better). Specs below both are identical batteries.

Group 27 Canada Proof P27DC CA 840 ; CCA 675 ; RC 180 ; AH not listed


I am looking for someone to help me determine what values I should have other than the defaults listed above, or should I just leave them as is.


I changed the settings to flooded, 200Ah, 12V. Don't know if I need to change any of the other parameters.

Any help/suggestions?

AFTERTHOUGHT - I guess it is the settings on the Tracer charge controller I would be changing, cannot change the title of this thread now...

AH is not listed because these are Cranking batteries. That's why CCA=Cold Cranking Amps is listed. your batteries are made for high cranking amps, not deep cycling. Wrong batteries for the project.

Weird.

The RV store sells these exclusively. It is the upgraded battery that came with my trailer. I had a credit for the parts dept and bought a second one to match, so I am not actually out any cash but I will be using them nonetheless.

I am an electrician, I contacted was at one of my battery suppliers last week and showed him the specs of my battery and he said since I already committed to one of them brand new he would buy another identical instead of buying 2 x 6V batteries. He said the main thing is the Reserve Capacity. Adding 2 x 6V would increase it but not by huge amounts, however added lifespan would be achieved. I deal with AC rather than DC so am ignorant on much of the subject regarding batteries.

When these batteries become paper weights I will get 2 x 6V deep cycle.

Anyways, what voltage cutoffs etc should I set the parameters to from the above picture... anyone? What AH rating should I set the controller to?

To make my batteries perform better and last longer I am sure I should set up some customization to the defaults...

thanks

I would not rely on that chart for your low level disconnect, 11.1 volts is too low. should be 11.9 to 12.1 volts for a 12 volt nom. system.

I guess I missed a main functionality of the controller. I thought the load output terminals were just for an accessory load, do I run all loads from whole trailer off the controller? The manual was far from clear, and it would be a piss easy fix as the splice is right beside the controller and I could easily remedy this.

I terminated the battery input off of the splice incoming, where the battery wires met the trailer load wires (in parallel with all the trailer loads). I never connected anything to the load terminals of the controller, my drawing looked like it was simply for an accessory load, will it handle all loads in the trailer?

Also, look how incorrect the drawing polarity is, the red to the negative on the battery with a note explaining the fuse to be on the positive of battery only... lol

Charge controller primary function is to regulate charging the batteries. Some (not all) have "load" terminals that can handle a small load, and disconnect it if the battery is dangerously low. Most Load terminals cannot handle much amperage. The manual will tell you

If my batteries are not deep cycle than why would they be marketed as deep cycle online? https://www.cdnrg.com/products/G27DC

It's weird though that my model is P27DC and these ha e indetical spec but G27DC. I cannot find that model anywhere. I assume the DC stands for deep cycle.
