The best way to know what mode the Renogy Rover 40 amp SCC is in is to look at the Main Page Display using the up/dn arrow keys. See attached pictures.
One picture shows the Rover 40 Main Page Display in MPPT Mode and the other is page 22 of the manual. In the picture with the Rover in MPPT mode the PV Array Indicator LED (not shown in picture) is solid. With Rover 40 in Boost the LED will flash on/off steady. With Rover 40 in Float the LED will quick flash on and then off.
Again the best way to know what mode the Rover 40 is operating is to look at the Main Page Display. Notice in the attached picture of page 22 of the manual it list the modes that the Rover 40 can display.
If using the Rover USER battery settings:
When the day starts in the morning the Rover will enter MPPT mode and stay there until
Boost Charge Volt(V) is obtained. The Rover will stay at Boost voltage for the
Boost Charge Time(Min) setting. After Boost Charge Time has completed the Rover will go to
Float Charge Volt(V) and stay at this voltage as long as there is enough sunlight. If clouds build or if the sun starts to go down the Rover will re-enter MPPT mode at the
Boost Char Return Volt(V). When night arrives the Rover will go into nighttime mode with moon icon and will not charge the battery. When morning comes the cycle repeats.
Note: The Rover should stay in MPPT mode if the battery voltage does not reach Boost Charge Volt.
