Why wouldn't running a generator any time you run the electric drives work just fine?
Isn't that the basic principle involved with modern train locomotives? Well, maybe not super modern, but I'll bet that magnetic propulsion
is a little ways off from the boating
Anyway, If you have a proper sized generator, anytime you need to use the electric propulsion, you run the generator. You make water
. You do laundry
(if so equipped). You charge up the pleasure vibe,etc...
And your house batteries are kept charged to optimum capacity.
Once you are intimately aware of your battery
capacity, you should know if it's OK to use the electric propulsion for a short burst or so.
What's the harm in running the one generator that could be multitasking so easily, where you would usually be running one or two diesel engines, or gasoline outboards?
Maybe there have been some growing pains with all this new fandangled electric propulsion stuff, maybe it's more just the owners not quite understanding the intricacies of battery
management and a life at sea relying on them?
For the past 12 years I have lived off the grid. Relying on my large 12volt battery, 1200 watts of solar
, a small wind turbine, my generator, and my brain. I run my super efficient, 12 volt floor heat pumps, 12 volt refrigerator
, and 12 volt lights. I also have a 2500 watt inverter/charger that is used for a few other lights, water
pump, etc. When I want to feel special and watch TV... I start the generator!
Well, at least in the winter around here!
Point being, I would think that these electric Lagoons (and any other electric powered boat) would want the generator running anytime they are using the electric propulsion for more than a couple of minutes.
If you run the electric motors for ~10 minutes, then get sailing and realize your batteries are significantly below their optimum state of charge, it will take probably 30 minutes of genny time to try and stuff the same amount of electrons back into batteries that you just pulled out in 10. However, if you just run the damn genny whenever you motor, you are not taxing the batteries at all! In fact you would be charging!
In the end, your batteries, and you, would be happy campers!
