A few more questions about solar panels...
As you may recall...I had some issues with my solar panels/batteries a few weeks ago. https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/30348700.cfm I've since bought a new controller (beca...

the little lights on the controller indicate when the controller is in BULK mode.
Bulk mode is the only mode where the panels full power goes to the battery. The panels should operate at approx battery voltage during BULK mode. As the battery voltage rises, panel operating voltage will rise to match that of the battery.
Other modes, power is limited to maintain a constant voltage. The panel is turned on/off to keep the voltage at a certain set point.
So the controller needs to be in BULK mode for your test!
