Recommend Alternator Regulator?

[ianc1200]

The domestic bank is 4No. 120 amp hours sealed lead batteries, 2 of them four years old, the other two two years (but same make/model type). I get the 15 min boost into the domestic bank, followed by 2.5 mins into the starter battery. One fault in the system is the cable from the unit to the domestic batteries, for it's length, according to the Sterling manual, is only good for about 70 amps (I think 40mm2 for about 3.5/4.0 meters) so am going to add an extra 60mm2 cabgle to see if this results in a higher charge.

Using my "Smartguage" last week I was 59% (full) at about 12.1/12.2 volts. Running for 6.5 hours got me to 95% full, by which time, and over the last hour, I was only putting in about 12/15 amps, which seemed low to me.

Your battery bank isn't big enough to get much higher charging currents.

Thanks, I did wonder whether I was trying to put too much in.

The modern Sterling Alternator to battery chargers ( AB series) may be what you want.

Thanks, Vic. The first unit illustrated is the exact model my friend has. Think you have hit the nail on the head, ta.

See also my recommendation for the same unit in post #7.

And also..."Alternatively, once your internal regulator is reinstated, you could use a Sterling Alternator-to-Battery charger, which has had good reports and doesn't need modifications to the alternator."

I think we all must have missed that

You will have to learn not to use joined up writing.
