Blue solar mppt 100 50 bulk light flashing & not charging

On my blue solar 100 50, testing the pv wires when disconnected from the mppt shows 90v. When the pv wires are connected, testing with a multimeter on the screw terminals reads 14v. I’m quite sure the panels and wiring are not at fault as I’ve tested them through a different MPPT…

any advise anyone?image.jpg

I would think you have a high resistance connection between the mppt and array.

Measure for voltage drop across every join/fuse/breaker.
