I want to know what my SP are supplying in terms of amps.

How about a DC clamp meter? While you won't have a fixed gauge you can easily get current readings from either panel. Actually a simple multimeter will work as long as the current is less than 10 amps

I asked this question on another forum but that was a generic electricians forum and I think either I was asking the wrong question or what I actually needed was misunderstood, I was given a possible solution but it meant having the two panels in series, something I cannot do, so hoping to get the another answer here.

What I have thus far in my 4 x4 is:

2 X BP solar panels, one is on a slide under the roof rack, the other on a long cable to enable
1 X Victron 75/15 charge controller as recommended by a SPF member and it works fine thank you. Since the original install a couple of years ago the addition of the Victron has enabled the batteries to charge a little quicker which is great.

I have the supply from each SP going to switches which in turn goes through an ammeter to the Victron, the charge output cable to the batteries also has an ammeter in the line.

I was hoping to see which SP was producing X amps, and also use the meters to work out the best orientation to the sun of the roaming panel for maximum amps.

The problem I have is I am seeing identical readings from the input ammeter to the output meter regardless of battery state. I was given an explanation but it did not actually relate directly to the issue or at least did not appear to, I guess I am just not articulate enough?

Can someone provide a diagram or am I asking to move the moon as it is not actually possible to do what I want? FWIW I use analogue gauges, LCD screen go black in direct sunlight and LED are unreadable.

Am I clear with this requirement/question.

TIA
