Hi all,
Know it is an old thread but I want to bring it back to life...
I want to install a prop shaft generator with a 24V PMA and searching for sailors that actually have one or two on board.
Are they any new prop shaft installs with a PMA then Carl’s one?
@pelaric: skip Novak what did you end up doing?
Owning a 36 years old VILM2 40ft Mono with a
Volvo MS28 gearbox with permanent rotating prop shaft and a fixed 21“x15 prop . A 13t swimming tank, officially a motor sailor but one of the seldom ones that really sail well too.
It didn’t break till now it won’t the next 10years.
So best conditions to run a prop shaft gen and I will.
Why:
I am going full
electric galley plus 2 fridges and 2 freezers, 2 electric autopilots as no
wind vane possible. 3 Tesla modules= 24V/17.2kW
Lithium Power of house Bank and 60AH LTO starter
battery. The “2 years old” 4x140AH lead acid
batteries from former owner going into bow (95mm2 cable from stern to bow already there) as 12V bowtruster/anchor whinch bank which also acts as dump load and backup house bank too.
Prepping the boat for my world circum the next 7-10years.
Wanna use all possible ways of generating electric power, first you can never have too much power and 2nd as things break it’s good to have as many backups as possible.
Power generation
concept:
Having a
ketch and a fixed pilot house 4x220W panasonic panels=880W of
solar fits on roof and Reling, another 440W bi facial LG
Solar panel on the davits/solar arch=> ordered and will be main source of power mainly at Anker and contribute while sailing too. contribute because 440W will be shaded and From experience the rest will maybe deliver 500W on a good day while sailing
Superwind
wind gen is already installed as 2nd generating power source in windy places like
Caribbean and works also during night and contributes a bit while sailing too.
Shaft gen will be 3rd power generating source and main while sailing.
4th source is Engine. That has a 12V/60A alternator now, will be Replaced with a 24V/80A and and an additional 24V/80A Heavy Duty alternator fitted.shaft gen will also act as 3 alternator and deliver power while motoring. Charging of 12 V LTO Starter and 12V bank with a 24V DC to 12V DC Sterling
charger.
5th source is semi permanent installed 230V 2000W
Honda suitcase with an external gasoline tank. Why:simply fits perfectly in an unused space close to shore power/inverter/charger location and an existing through
hull could was used for the
exhaust where no
diesel one would fit. 2nd gasoline and very efficient,3rd
cheap with good
parts available worldwide and 4th reliable.
