Classic 150's charge times not resetting at night

[Rejuvenation Farm]

I have (2) 150's set up in "follow me" mode.  Within the last few weeks I noticed that the master 150 was not consistently resetting in the evening during the resting phase.  Any ideas why this has started happening?  I am running firmware 1933 (01/08/2015).

Well I looked and they are up to V. 2126....  an update never hurts...

I plan on updating soon.  Not sure why that would be the cause of this issue though.  It has been working great for the past year or so and nothing has changed on my end that would impact the CC's.

have you tried a VMM?  alias a Factory Reset?

Power down PV then Battery, press both L &  Right soft keys and while holding the keys IN then Power up the BATTERY , you should hear the fans test and shut off then the MNGP screen comes alive... now release keys... RESET all settings, if you saved them ...

enjoy

I have not tried the factory reset - I will give it a go this evening.  I have been physically powering the units off using the breaker switch on my inverter to reset the charge times.

I power down both, as above, and then let it rest for  up to 1 minute.... and always power the PV on last. 
Sounds like you did not shut them both off...??

[Rejuvenation Farm]

Yes - I have manually shut both down a half dozen times now hoping it would fix the issue.  Sometimes I will go nearly a week with them resetting normally, then as soon as I drop my guard, I get burned.  I never had this issue before - it just popped up out of the blue.

Hi Rejuvenation..,

It is not exactly clear (to me) just what is,  or is  not happening,   and just what is the effect of that on  the Classic.

When the Classic transitions to Float,   the Absorb Timer is reset to the Absorb time setting in the Charge menu.   In a normal situation,   this transition to Float occurs before the Classic  Rests.

There is the Auto Reset function,   that when is set to ON,  begins a new day at 23:59,   each day,   and "ReBoots"   the Classic.   Most of us run Classics with ARST =  ON.

You might want to check in the Tweaks menu,   to see if   " ARST "  is set to ON.

What is the situation that you are seeing?

Is the Time Of Day Clock set correctly in your regular Classic (not a Classic Lite)?

Thanks!   Vic

Hi Vic,

Thanks for your reply.  ARST was set to "off" on both controllers.  I turned it on for both.  The time and date was correct on both CC's.  I will let you know if this fixed the issue when I get check them tomorrow morning.

Gracias
