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!!!

900W 3 × 300W No name brand Poly panels, Morningstar TS 60 PWM controller, no name 2000W inverter 400Ah FLA 24V nominal as a backup system.
5Kw Yanmar clone single cylinder air cooled diesel generator for rare emergencies 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 .
