Sounds like a good plan.

Look at Trojan's competition though like Deka/East Penn or US Battery. Comparable performance and lifespan at a better price.

Re: 6v or 12v batteries

My current bank is 6 Deka 6v GC batteries, supposed to be equivalent to T 105s. I would have bought T105s had they been available. I think they use the same plate construction as the T 105s which is supposed to give longer life but lower CCA.

They are 4 years old now and still holding up well. Mostly they get pretty lightly cycled and get back up to 100% fairly often as I have 400 watts of tiltable solar.

Re: 6v or 12v batteries

There in lies a dilema.
We need some more solar panels but what is the point when the batteries are not holding the charge too well. Our bank lasted 5-6 years which was pretty good really so I cannot complain.

The sea pronounces something, over and over, in a hoarse whisper; I cannot quite make it out..
