Outback FlexMAX 80 issue...

I am hooking up my solar... I have 4 325W panasonic HIT panels and an Outback FlexMAX80 Mppt solar charge controller charging 4 Apex AGM 250A/H batteries(1,000AH total) in a 24V configuration. The problem is... when I turn on the PV array, the MPPT shows the correct voltage coming in and within about 8-10 seconds, the input amperage goes from 4A to 1.5A (it is in the morning and no clouds are visible. Basically bringing the voltage of 1 panel. any Ideas or suggestions? I have ruled out the parallel collection coupling as I now have 2 panels wired in series with the same issue. The voltage does not drop just the amps. Any help would be appreciative!!!

Second system 1890W 3 × 300W No name brand poly, 3×330 Sunsolar Poly panels, Morningstar TS 60 PWM controller, no name 2000W inverter 400Ah FLA 24V nominal used for water pumping and day time air conditioning.
5Kw Yanmar clone single cylinder air cooled diesel generator for rare emergency charging and welding.
Main daytime system ~4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformer
Night system ~1kw panels into 1xMNClassic150 700ah 12v bank morningstar 300w inverter
First off you have a 250ah system, not a 1000 ah system (assuming your batteries are 6V.) Second, if your batteries are fully charged that is exactly what you will see. So I don't see any problems there.
"Basically bringing the voltage of 1 panel." - Your array voltage will remain pretty much the same no matter what. Only the current will change.
Do you have a load you can put onto the system, inverter or such . With a load it should increase in amps out .
