I want to install an isolation/step up transformer between my generator which supplies only 120V and my breaker panel.
The main purpose of the transformer is to take the 120V and make it split voltage 120/240V so both legs of the panel can be fed properly from just a single 120V supply.
The main problem is I would like to use a 5-10kVA transformer and finding these used having 120/240V - 120/240V windings is proving to be a challenge. However, finding 240/480V - 120/240V seems to be easier.
Basically I'm thnking that using the 240/480V - 120/240V transformer backwards and feeding it 1/2 the voltage on the 240V secondary winding would accomplish my goal.
So, the million dollar question is, do you see any reason why I can't feed 120V to the 240V secondary winding which should then provide the 120/240V split phase/split voltage I'm looking for off the primary?
(Yes, I'm aware of needing transfer switch to prevent backfeeding the utility, etc., so no need to go through that.)
I just figured that it is easy enough to just get a 3 bank so when the boat is not in use I can keep all 3 batteries charged. I have not bough a charger yet, maybe I will give it some more thought.
Edit: After thinking this over, with the size, weight, and heat output of the charger (as well as the cost) I think it makes sense to just
buy a 2 bank charger, I have a smaller charger i can use on the starting battery when the boat is sitting at home. Forgive me, for i am a retired engineer and I have to obsess over everything...
Congrats on the motor! I think you’ll like it.
I can’t say much on the charger location but I’ve seen them under the lid in back compartments and under center rod lockers. 160 degrees is more than I expected to hear.
Curious why you’re opting for a 3 bank charger with a 24V trolling motor. Unless you don’t feel you be running you big motor enough to keep that battery up as well?
I did buy an Minnkota Ulterra, thanks for the recommendations. I had a bunch of Cabela"s bucks saved up, which helped. Now i need to
get an onboard battery charger. Where do you guys mount these things in your boat? The manufacturer I am looking at {Noco genius)
says tht their 3-bank charger will run at 160 degrees, seems like a lot of heat in an enclosed compartment? Thanks for any input on this.
Wasn't terrible at a state park beach. Antelope island maybe. I wouldn't recommend it as a beach destination tho. Figured I was there, I'm getting in it.
