Happened upon a post made a year or two ago about replacing a fridge compressor
run of a pulley on the engine
crankshaft with a large frame alternator
Would like some opinions as to the feasibility and options available if you'd be so kind.
I'm out in Singapore
, so the usual stuff like Balmar
tend to be pretty pricey.
I've got a substantial mounting at the front of the engine
to house a large frame alternator
, so no worries there. May need to upgrade to a serpentine belt for the bigger alternator though? Not sure here.
I currently charge mainly with Solar
, as my usage is usually only at weekends. I have a 450ah FLA (6v trojan) house bank.
My 30hp engine has a weedy 20amp alternator on it.
What I'd like to do is have a switch that would allow me to (electro clutch) engage a big alternator to charge the batteries with the engine at anchor
, or while under sail in neutral.
What do you reckon is the biggest feasible size of alternator I could use (given I'd not be using it at the same time as asking the engine for propulsion
, if indeed this is possible)...?
The idea behind the big auxillary alternator would be to recharge the house bank quickly, if my indented dc loads (from new fridge, and perhaps aircon in future) deplete the bank faster than the solar
can keep up.
