For the last seven years, everything has worked faultlessly with an Adverc 12A B2B charger at the bow keeping the two 110ah batteries topped up.
Last winter I changed my aging l/a domestic batteries for lithium which are so efficient that I’ve not needed to mains charge since March, my modest solar array plus wind gen meeting all of my needs. (This being a sailing boat we try to use the engine as little as possible)
The problem now is that the B2B charger doesn’t kick in unless there is a constant nine or ten amps flowing into the domestic bank - about the maximum on a clear, sunny day with the panels perfectly aligned. Even on a blustery day like today the wind generation is not constant enough to keep it working.
In the spirit of one problem solved leading to at least one new problem - I now find I have flat windlass batteries.
As ever: any suggestions gratefully received…
