In the second image, your inverter/charger has qualified AC power being supplied to it so the AC INPUT led is lit.
panel is reporting that the DC system voltage is approximately 12.5 VDC, which seems low when the DC AMPS leds are considered. (More on this later.)
The panel further shows that the inverter/charger is supplying approximately 30 amps. Assuming that the I/C is correctly installed, this means that those 30 amps are being supplied to the battery bank. Assuming that the battery bank also supplies your house loads, some of that 30 amps that is being supplied by the I/C is supplying the house loads that are currently (no pun intended!) energized. If no DC loads are energized, than the 30 amps is all going to the bank. If there are no DC loads energized, then the remote
panel is indicating a problem with your system.
The Freedom 20 has the capability to output as much as 100 amps. This charging
rate requires 21 amps of AC. The charging rate can be reduced by the operator to ensure adequate AC is available to run other AC loads on board.
As a battery bank is depleted, its voltage is reduced. When a charging device is turned on, the device will output voltage near the original battery voltage and the current will approach the maximum of the device. As the battery bank is charged, the voltage slowly climbs until it hits the bulk/absorption voltage point (nominally, 14.4 VDC) where it holds steady until it hits the float set point (nominally, 13.4 VDC). Meanwhile, during the bulk charging phase, charging current from the regulated device (the I/C in this case), is putting out its maximum charge. Once the absorption stage is reached, with voltage held constant, charging current slowly decreases until the regulator
trips the device to float.
Assuming that the I/C has not had its charging output reduced, and that there are no sizable DC loads energized, than 12.5 VDC with only 30 amps being produced is an abnormal indication.
