Hello,
I have a solar system with 2 panels in parallel to increase current (each panel around 3.5A max) so in ideal conditions the total amount should be 7A in total.
When measuring short circuit current (connecting + and –) between the 2 panels in parallel (no controller attached) I read around 5.2 A (which is OK)
When I connect the panels to the controller (see picture attached) and attach a digital multimeter between panel and controller I am measuring for A1 –> 2.3A and A2 is also measuring this value.
But when I disconnect or remove my digital multimeter A1 I suddenly config.pngmeasure 5.2 A on A2 between controller and battery.
So why is my current decreasing when I want to measure A1? Shouldn’t it also measure 5.2A???
