How does the wiring for your "battery meter" (Magnum monitor) get to show the amps to the battery from the solar controller? AFAIK you need a shunt somewhere there.
Morningstars will give you amps for solar, battery, and load. No need for a separate monitor or outboard shunts.
Have you a Morningstar link confirming that?
Many controllers will show "PV amps" and "Batt Amps" but that is just the input and output amps. They can't show how many of the output amps went to battery. "Load amps" would only be for the loads connected to the controller's load terminals--but loads don't have to be on there, they can be on the battery so the controller would not "see" those.
Googletard. All the manuals can be downloaded. The MS controllers will report/record current on each set of terminals, solar, battery, and load.
If you have load amps on your battery terminals (except for really large loads, like an inverter), you're wiring it wrong. Other than that, 30 or 40 amps of DC load is a lot.
