How do some of you power your battery if you stay out there for a week or two? Right now I have only the runing lights on it, but I would like to add more items but I do not know whether to go for solar or generator. Any experience among you folks? Phil
Hi Phil, My experience with solar says you need too big of an array to do much good for a cruising boat, with any high power draw electronics. Not saying it doesn't work, just saying your at the mercy of the amp hour rating, the size of your battery(s) and the available sun. There is a WWP19, named Chubby who spent a month cruising to Hawaii. The skipper carried a Honda 1000 generator and charged batteries for about thirty minutes every day of so. I have the same generator, works great! I will however replace it with the next size up, the Honda 2000. They claim both are "clean" electricity. Meaning you could run a laptop from the 120v plug. I will go one step up so I can run it to use a microwave. Notice that when you look at generators, most have a direct plug in to charge batteries. I currently use mine to charge a small 12v - 12amp battery, which I believe goes to a snowmobile or maybe a jetski. The battery is a gel cell and sealed, so there is no chance for spillage of electrolyte. Even with a wired battery box, the entire set up is only 9 pounds. There are lots of sizes available, all the way up and over 20amp in this little battery. More amps = more dollars in this case. You may be told by folks like West Marine, you have to buy a high dollar charger for the gel cell. Not necessarily so, especially when you are watching the battery. You shouldn't leave it overnight on a regular charger - as you would a float charger (for gel), but it is acceptable to charge with the Honda generator and disconnect when the charger turns to trickle. For me that's about 30 minutes. I run a (truck cab style) electric fan, two xenon cabin lights and navigation lights, when needed. I charge the battery about one in 3 to 5 days. Even with no useage, it is recommended to charge this type of battery every month or so. They are not necessarily a deep cycle, however they last a couple of years, as I've been using them. And, they are way less than $50.00 at Wallyworld. A little more at Batteries unlimited. If you have a 12v deep cycle already installed, find out the amp rating of the battery, that will help you determine the amp hours you can draw, before you must re-charge. Next, determine the amount of draw in amps for each piece of equipment. If you are all LED, you can probably go for weeks, without a charge! If only we were all so fortunate. Ayway. make a list of the equipment and the rating of each. Compare that to the amp rating of the battery. An example would be my battery is 10 amp. The fan I use is rated at 1.5 amp. I can run that fan at full speed for about 6 1/2 hours (10 divided by 1.5 = 6.6). I am sure there are more difficult ways of explaining this, but it still comes out the same. You use the amps, then you recharge to get them back. Another real time benefit of the Honda generator is they are 4-stroke and use the same gas used in the Honda outboards. The downside, they are expensive! Bill On 9/2/08, Phil & Frances <srelt@iclub.org> wrote:

Bill, Where do you store your generator?? Phil, How long will your batter last just running lights? In a nutshell I'm in a similar quandry. I don't know how much the 3amp charge off my outboard will do. I just bought a new M17, Seafrog, and am starting from scratch as far the electrical system is concerned. The only power requirements that I am looking for right now would be LED running lights, a couple of interior cabin lights, a Garmin 276, one or two Hella fans, compass light, masthead and spreader lights. Not much else. If I stick to LED for all the lighting requirements, that should helpgreatly. Do I need a deep cycle battery either in the 24 or 27 size? I understand what Bill is saying about using amps and putting them back into the battery. Is it as simple as going through each electrical component and multiplying the amp usage by the number of estimated hours it would be used between charges?? If my outboard charger is a 3 amp charger does that mean it will put back 3 amps back into the battery in one hour? Oh, why didn't I stay awake in those classes???

I'd have to take a photo to explain the generator placement. I had a Sunbrella/vinyl cover made that has end straps and a stainless zipper that runs the bottom ledge. I can tie it down just about anywhere there are two anchor points. I'm not sure how to classify LED lights. I myself do not bother to add their miniscule amperage draw into the equation. I based my system on the stuff I cannot control. I too use the Garmin 276. I also have a fan. But what most little craft do not have is 120v. I like that feature allot!

yes!? that is a good question.? I too would like some insight.? We have a med device that needs one full charge of battery power per night so.? we are limited to One night stays.
