I will be converting my yacht to electric
(yes I know its wrong and diesel
is mans best friend, blah blah blah) I have been looking at a number of kits which all seem to be based on 24-48v DC motors. When you want to add re-generation into the mix most add an additional unit which will do this (you guessed it, at an additional cost). Plus with DC you have Brushes
to factor in.
So I started looking at what the electric
car guys are doing, a large number appear to be moving towards 180-240v AC motors. Paraphrasing them - AC delivers more re-gen and has less maintenance
due to the lack of brushes
I have found a local supplier of 240v AC motors to suit my boat. The engine
is 5.5kw with an operating rpm
I have measured by available space and can fit 12x6V/210AH batteries to run the motor
This is where my knowledge starts to run thin, I am aware I will need to convert the DC to AC for this I have tracked down some large inverters on eBay. See the link below.
18000WATT PEAK 48V PURE SINEWAVE INVERTER 70A CHARGER - eBay Batteries, Electrical, Parts, Accessories, Boats, Watercraft, Cars, Bikes, Boats. (end time 08-Jun-10 20:00:50 AEST)
I need to know if this type/size inverter
would be up to it.
If AC is indeed the better option, or if I should return to DC
What additional gear
will I need, ie; some type of throttle would be handy
I'm sure more questions will come of this discussion, and I still open as to what I do with the total set-up (except going back to diesel
, my wife is highly allergic to it)
