Absorb set to 55.2v. Classic goes from Bulk to absorb at 54.8v

Thanks Vic,
Yes now that you explain it I do remember reading about this in the past.
I guess it just takes a bigger load to drag the resting voltage down to let it get all sorted out .
Looking at it now hours later it is in Float and holding the system amps at zero but feeding the loads so it is all good.

I was watching it closer today since I had needed more power. Since the 48v lithium and 24v lead acid share the same combiner box with a split buss bar - I was able to take a string of the PV and switch it over from 24v to 48v system quite easily - all the strings are the same so no problems there. I just wired from bottom input of one breaker string to another breaker on the 48v buss bar. All I need to do is switch breaker to 24v off and breaker to 48v on . Simple !  here is my first attempt at using paint to make illustration

Hi Larry,

That is a neat trick with the Combiner.

I will not mention what we do sometimes,  in switching things around in the Combiner,   HOT ...

Have fun,   Vic

Gotta make life interesting eh Vic ?

Well I did this hot - at least the one connection was - but I tried to be very careful.
The Midnite Din rail breakers do not clamp down on stranded 10 gauge very well - kept coming out - at least the type wire I was using - maybe more fine than course . I finally gave up and found a small piece of 8 or 6 gauge to use on it .

I have some of those insulated screwdrivers now too - so used those - makes it a little bit safer.
