As the topic says the I have two Classics in follow-me mode that exited Absorb to early (only in absorb for a few minutes) and then went into resting state and have been sitting there for 60+ minutes. It is still only mid-morning here in Australia. Arrays are still both connected and volts are present at the classics, tested with meter. I fund the following info:

Step1- Is the Input voltage 0 on the MNGP(Display)? If so check for reverse polarity on the PV input to the Classic. If not reverse polarity than call customer service.
Step2- Go to the Mode menu and make sure it is in Solar and On. If not set both and press Enter to save and this should fix it.
Step3- What is the PV voltage? is it at least 133% of the actual battery voltage at this point? If not the PV voltage is to low.
Step4- Make sure the Battery voltage is below the actual Absorb and Float voltages at this point?
Step5- Click Status several times until you see Classicxxx connected to a xxV battery. Is the xx for battery voltage correct? if not do a VMM
Step6- Try switching to Legacy P&O and see if this mode works?
Step7- Check the reason for resting. From the main screen hold the left arrow and tap Enter. The number between In and Bat is the reason for resting. Please call into customer service with that number for assistance
Step1: All OK
Step2: All OK
Step3: Voltage OK
Step4: Battery Voltage is below the absorb setpoint but higher than the float setpoint
Step5: Couldn't find this oneStep6: No Change
Step7: 29
However in Located in Aus so too expensive to call. Email response might take too long as I need the charge while the sun is up.
I'm unsure of how to do step5.
Any thoughts?
do you have a WBjr?
Are you using end Amps to suspend ABSORB phase?

Yes I have a Whiz-Bang Jr and shunt on the standard Classic 150. Also actually noticed the 2nd classic (150-SL) had AUX2 set to Whiz-Bang Jr but it didn't have it installed. Set to off manual but no change.
I already rebooted the classics in case it was a glitch. If not It should reappear today or tomorrow. Will let you know how it goes.
UPDATE: It's resting again.
Step7: now reads 38
My loads according to the Whiz-Bang Jr are -1.8 amps on a 48v 280A battery bank. My new commissioned system is to run most loads at night but the internet devices and phones 24hrs a day.
ReasonForResting = 38 8-4-2015 External charger. zero watts @ above set point 90 sec
38 is a relative new RFR # and will rest if the voltage stays above the set point for >90 sec.
It should come out of resting if the voltage drops below the set point.
Hmmm I just posted what RH did but it seems to have flown the coop???
Search for RFR 38 and you will see the original reply by boB...
ADD: what do you have the EA set to?

Ending Amps is 5.6A or 2% of bank capacity.
Turning off the power to the Classic 150 SL (in follow-me mode) and leaving only the standard Classic 150 has resulted in normal operation without any resting periods.
UPDATE:
Might have found the issue had the float voltage incorrectly set @52.2v instead of the correct 54.8v. In researching the above info I gather that the lower voltage setting could cause the charge controllers to switch off as it may have taken more than the 90 seconds for the surface charge voltage to drop off from the absorb setting to the lower float setting therefore making it seem like the batteries were still being charged by another source at a higher voltage.
As above the most likely reason for this is that theres another charge source holding the voltage high. You said that the bat voltage is above float, did you mean absolute float or tcomp float? Its also been known to occur with lithium banks that resist the drop to float.

absolute float.
Did you get this solved? RFR 29 is "insane wind curve"
So if there is still an issue I would wonder if these had a firmware update and no factory restore?

Did the firmware update then the hold two arrows factory restore. Anyway it's the next morning hear in Australia so I'll be able to see how it performs today. The problem occurred when the classics exited absorb to go to float so I assume the reason I found above to be the cause. Will see how it goes this morning after finishing the absorb cycle and report back.

Yep, the same thing happens when you do an Equalize. The surface charge on the batteries is higher that the Float set point. If you have a good load on the batteries it probably would come down faster. boB said it checks back every 15 seconds, "The Classic will stay in Resting for at least 15 seconds before re-trying to give the battery voltage
a chance to drop below set point."
