Solar on a small TT
I'm looking at a small travel trailer (starcraft satellite 17rb) which is only about 20ft long. Roof is composite one piece without much of a flat area. One thing that I absolutely want on my next R...

Hi brulaz,
At 6000 watts of storage there may be four 12 volt jars--so I'd jump to 48 volts. My gut feeling is that there are more devices at 48 volts than at 24.
IIRC 2oldman went from 12 to 24, and found it less than pleasing so has jumped to 48 volts.
I believe time2roll stayed with 12 volts--but has 600 watts of solar. His generator lives at home now.

If a person had >2000W loads, I would go up to 24V and perhaps specify AGM batts.
Under load the 24V will halve the %V drop of batteries, wire and connectors, and AGMs tend to drop less V than FLA in the first place.
Even with our 2000W inverter and <2000W loads, 24V has been very helpful.
