solar options
Last summer I had a 240 watt kit(from Solar Blvd.) Installed on our MH. It has two 120 watt panels feeding a 20 amp charge controller. I recently had the two stock 12 volt marine house batteries rep...

"So, then if I set my adjustable Voltage Charge controller voltage to 15.0V, does that mean my T1275's will get an actual 14.8 volts from my solar panel? "
You need a voltage spread but not necessarily 0.2v. I got that 14.8 /14.6 from an earlier version of the Iota website.
It depends. I think the PD expert on here said it was just a tiny spread needed and a lot of the spread you see is voltage drop on the wires.
Solar controllers are even more fun where you have losses in and out and who knows which voltage the adjustable setting sets? I suggest a trial and error measurement and see what makes it come out right to 14.8 Of course that 14.8 is only for 77F and it should be higher when colder and lower when temp is higher.
It does have temp compensation, but a 150 amp/hr T-125 is not going to get hurt by .1V extra if set to 15.0 with only 6.6 amps max coming out of my 120w solar panel, under ideal conditions. It's relative. Battery capacity % to charge capacity %.
