I have 4 200ah gel batteries in serial and parallel connetion so sytems is 24v and 400ah. Just want to make sure make sure that my MPPT settings are correct. I have pre-setting 2 in use now, but this is info from battery manufacturer. So shoud I use these values?
Absorption 14.4*2=28.8
Float 13.5*2=27
Temperature compensation -30mv/C
Hi @beavis
I'd customise the standard profile and save it under a new name. There's not much in it, but why not?
I like that you've chosen the lower end of the batt maker specs, that's a great thing with paralleled strings.
The Temp Comp also needs the '*2' factor applied, so -60 there. That's actually quite a high figure, and you may find it's the max available on the mppt. If your 100/30 is standalone it only uses this at daybreak, so you'd need to keep an eye on things if your batt temp follows weather variations.
