Re: Small generator + electric propulsion for dingy

I never really intend to use this, it is only for emergency, if I need to travel 50 miles in the dinghy. I don't ever expect to need reduced power, or any power actually, so I really could care less...

That's rather similar to my frame, but my frame pieces hinge at the crank bearings, my seat post holds all the upper frame parts all together. The main difference is my wheels can come apart and...

Re: Challenges with Solar on boats

How does the amount of useful power change when you take it out of one 12 volt battery that comes from a 48 volt series connection or it is just standing by itself. Normally when you have multiple...

Re: Challenges with Solar on boats

There are losses in all electrical systems, but with solar we are working with such small amounts of energy so it is important to conserve what ever we can. Sure you can solve this with bigger...

Re: Challenges with Solar on boats

let's look at an imaginary typical system, 3 100 watt 12v panels = 8 amps per panel

installed in parallel at the back of a sailboat to reduce shading problems, thus 24 amps in a wire.

Re: Challenges with Solar on boats

I remember now why I wanted to go to higher voltage, it is efficiency, the loses in the wires are due to the current not the voltage, at higher voltage and reduced current you have much less loss. ...

Re: Challenges with Solar on boats

On the surface I have to agree, I'm trying to remember what got me to wanting to hook the batteries in series, it had something to do with charging efficiency of the controller and voltage I think. ...

Re: To contact, or not to contact?

Contact anybody and everybody that might know something before you put down any money, do you homework before not after the deal.

Re: Small generator + electric propulsion for dingy

Re: Challenges with Solar on boats

There is a good reason for discharging one at a time in my setup, you can't have 4 batteries in series for charging and in Parallel for discharging at the same time. It's either one or the other. ...

Re: Challenges with Solar on boats

Answering my own question, I'm pretty sure this system would only work well if the house battery is switched many times a day to tend to equal the discharge of all 4 batteries. I would assume, but...
