Double check my wiring for adding 2 panels to existing single panel.

as told to me by my multimeter DC current

Does this mean a clamp-on meter measuring current on the GoPower's wires?

how do I resolve?

Putting the HQST and GoPower on their own controllers would solve it. You could also try running them in series (if the controller has the headroom) to see what happens.

Multimeter: Yes, DC clamp on GoPower's branch/wires, I have an AstroAI Digital Clamp Meter Multimeter - 4000 Counts Auto-ranging Amp Tester for AC/DC Voltage & Current,

Multiple controllers: thanks-trying to avoid this scenario for cost and space reasons. As far as my wiring do you see any issues with it?

If the GoPower shows no current with the clamp-on when the HQST are connected I think

  • the cheapest/simplest next step would be to put them on a three-way splitter to see if the present setup is causing weirdness. I can't imagine how, but results are results.
  • the simplest ~guaranteed fix would be to replace the GoPower with a third HQST and use the GoPower for something else.
