Hello Dave,

Excellent article, though I will offer a couple of minor "picks".

1. There is an extraneous note just to the right of the picture of the TCR and Diode that should have been removed.

2. In the diagram of the electrical system, the fuse on the house battery should be between the battery itself and ALL of the connections. (And the current requirement under ABYC is "within 7 wire inches") The start battery connection to the starter is exempted (due to the large amp requirement, the voltage drop potential across the fuse and the possibility of the fuse interrupting the starter circuit under low battery conditions (when the current goes up even more)) but any other connection really should be fused as you show.

My personal preference is for a voltage-sensitive combiner instead of a diode, but this certainly introduces yet another "gizmo" (and potential failure point) into the system :)

Thank You!

Thanks for the comments Hartley. We are about 30 mins from getting underway for W Papua. I will follow up when I get back to internet next month. Again thanks for taking the time to comment. They will remain here as additional info for the article. Dave

Some useful details on the components we bought to put this system in on our new-to-us catamaran. Parts can be found online from Mouser Electronics.

The Schotke Diode is #MBR6035 and costs $16.68 and the Thermal Circuit Breaker is #0813020.ZXST and cost $13.84. We mounted them on a piece of scrap aluminum L-bracket. It works great.
