My yacht has a 75Ah house battery
, 30A Hitachi alternator
and a small (5W) solar
panel. In between sails
(mostly day-sails, occasional overnighters) I find the house battery
is running down. I run the engine
for 45min to an hour on day trips, longer for overnight.
It seems from what I've read and heard that a smart regulator
would allow the existing alternator
to charge the battery much more quickly, and to a higher percentage charge, in a given run time.
Seems no point getting a bigger battery, as I'm confident the problem is in the charging
capacity. I guess I could swap the alternator for a 50A one. Increasing the solar
panel would help between trips, but not much when I'm out for a few days.
Sooooo....... I'm looking into smart regulators, and I'm having trouble finding anyone here in Oz who has actually installed one and can comment from experience. There's one brand from the UK called a Sterling that looks well-priced. Love to hear from any of you clever blokes who've actually put one in: was it worthwhile? Are they that good?
