Amp reading on MPPT regulator

After installing a new Epover Tracer MPPT solar regulator, I get low 3 amp readings on the display, at noon and the battery run down to 12.2V. Connecting my quality multimeter to the solar terminals on the regulator, I get 8 amps (two 100W panels, 19V). After hours googling, I am stumped. Any suggestions?. (I had a connector box problem, and one panel my not be working. Hate to break all the fancy insulation to check..).

Re: Amp reading on MPPT regulator

Could it just be the Tracer display is wrong? I don't believe the brand is known for high quality products.

A couple of thoughts:

How are you "connecting your multimeter to the solar terminals on the regulator" and reading Amps?

If you are getting 8 Amps @ 19V out of 2x 100W panels, then both panels are working.

What loads are on the system. If you are getting 8 Amps from the panels but only 3 Amps into the batteries, that would suggest that you have 5 Amps feeding other loads. Fridge? Instruments? Radio?
