Hi,
New to this forum and I've a question;
I use 8 Cosco 6v GC batteries wired 4x2 for 24 volts and 440 AH. They are reasonably new and very cold in an insulated box in an uninsulated shed here in the upper Midwest.
The panels are Salvina 270's and wired 3x2 for 1600 watts max. The charge controller is a Midnight 150 classic with the new software update.. I have had several different opinions on charging voltages. Some say use as low a voltage as you can to get to float, then use a higher voltage once a week to stir things up. Others say use a high voltage all the time.
What voltage settings should I use for Absorb, Float and equalize? Keep in mind that due to the cold batteries, the Midnight will add 2 volts to whatever I set.
Thanks
