Hello all, I have looked through the posts that have been posted, but I thought it would best to start my own rather than hijack another.
I am working on a boat but it should be similar to a car. I have a 60v 3 kw AC induction motor powered by 5 lead acid batteries. I started out with a Honda 2000 and a 60v 10 amp charger. This works to charge the batteries, but it only gives me 10 amps to run the motor. I need closer to 60 amps. I also just put together a 5.5 engine and a big truck alternator with a dummy regulator so I can run it up t o 75v. I have not tried it out yet but it should work. While researching the project I came across many other options. So now I am asking the experts what do you think is the best way to accomplish my system.
The Honda 2000 is a nice package small and quiet. Generates AC converted to DC then inverted to AC. any way I can utilize the DC before it gets inverted?
How hard is it to just build a 75v charger from 110v. Not automatic, but manual so I can adjust the Volts and amps. I want to run the motor as I charge the batteries, but then also just charge the batteries at a lower amp setting at times. I do have solar to top everything off and keep them balanced. One solar panel and controller to each battery.
Thanks in advance, Dan
