27DCs and SG Lag Problems
Here is what I mean. Got two rebuilt 27DCs from Interstate as "Econo Power" models, which means they are whatever brand and type they decided to renew and sell at under half price. So just right fo...

so for all you guys that do these high eq charges, are you disconnecting your loads? i would be uncomfortable running over 15.5 with stuff still connected. not sure how your doing hours of eq, and still using your battery's?
Yes you must disconnect from the rig's 12v systems. Eg a Norcold fridge says don't go over 15.4v Ideally you should also isolate each battery (except a pair of 6s) and do one at a time, but if doing split bank that may not be practical.
In the field, you can do a split bank trick if you have enough batteries. Run the rig on one half of the bank and equalize the separated other half. If doing that with solar, wait till the forecast is for several nice days in a row. Split the bank and put all the solar on the disconnected half to get it full before dark. Then next morning, it is still full, so you can go on to do the equalizing that day.
Now put that half back in service and do the other half the next two days. Takes four days. (Actually you can do the second half later if it gets cloudy, so you only need two good days in a row to do a half)
If your solar controller will not do an equalize at 16v, you can by-pass it and go panel-direct with 12v panels. Watch the voltage so it doesn't go above say 16.5.
It is not easy to arrange all this with solar set-ups that are built in and hard to get at. Much easier with portable solar sets.
