New EASUN charge controller installed and went into “Night Mode, No Charging”.

Yet battery voltage is only 56.3. Default settings:
Bulk: 59.2V
Float: 58.4V
Absorb: 55.2V

I have the manual. It is maybe OK. Dancing with electronic keys is not my forte at all. I can’t even get the temperature off of the C/Celcius setting. 

4.2 star rating. I have found ratings below 4.4 to indicate incoming issues. Which can usually be overcome with a time and anxiety price being extracted. 

* Should I Just wait until tomorrow morning and see if it likes charging batteries sitting at ~ 48.4 volts?  This string is not required but I got it done for less than $250. So why not. Bad weather happens. 

*Or drive myself nuts pushing, so far, uncooperative electronic keys? Maybe fix it? Maybe it is already ok?

    118 volts from three panels. Voltage taken right off of the panels.  145/150V charge controller. 

    A lot could have gone wrong. I’ll troubleshoot further tomorrow. Or so. 

    Dancing with electronic keys gives me the creeps. I’ve had some bad experiences. I am not real good at it.

    I had a situation with a Midnight solar controller one time where the internal clock was wrong and it was doing something similar to what you're saying is happening. Check to see if there's a clock in that controller

    2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old  but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric,  460 Ah. 24 volt LiFePo4 battery bank. Plenty of Baja Sea of Cortez sunshine.

    So I managed to blow up the panel diodes again. Doing the same thing as the last successful string - I think. Usually I don’t blow up diodes. Usually. 

    There is something important that I forgot to do? 

    Replacing the diodes underneath the panels will be pretty uncomfortable. May remove them for easier access.

    Didn’t blow up the diodes after all. Harbor Freight voltmeter quit working properly - lead then fell off.
    Back to remounting and troubleshooting. Solar can be a challenge for those not electrically gifted.
