I totally agree that a diesel hybrid is the way to go. Maybe in 5 years there will be new battery tech that can deliver 2x the kw per kilo of battery weight. Right now what you are saying is accurate for the times. Also one thing good about diesel is if you have to make your own fuel you can. you know end of world stuff or the world says no more fossil fuels period. I do love how you explain everything you are doing and why. You are very logical and I can not wait to see you out on the oceans.
I was a bit surprised that your site seems to be in a residential area. I was looking for a space to do a rebuild in Florida and residential areas are out of the question there. Just a bit concerned that your neighbors will cause you grief when they grow tired of the construction noise -
Well, on two sides of the lot are a noisy businesses. so this is kind of half residential. Then, the house in front is owned by the same person who owns the lot, so that's not a problem. That leaves the fourth side, which is a house, but we spoke to people living there prior to renting the lot and they are cool with the project and are used to noise from the other businesses next to us, And since this is a precut kit, saw noise will be kept to a minimum. There are only occasional times when we have to make a lot of saw noise and will make sure to do so during the day. Power Sanders are not as loud, but we also won't use those during sleeping hours. This was our best option and San Dimas was one of the only cities that let us build on such a site. Actual boat yards wanted $60,000 for two years and were an hour commute, at best, while this was less than $10,000 and two minutes from my house. .
@@SailingSVLynx that is Fantastic! I was looking to do exactly what you did with the “off grid” set up- but wanted to use a container on each side with the “tent” that goes up between. But I would have to go out to the farm lands of Florida to even think about it. Great set up you have! Look forward to next week!
Those are good solar panels for 48V. I saw another 48V install recently using 2x400W Sunpower Maxeon 3s (65.8Vmpp, 75.6Voc) in parallel in Aussie and they were producing 820W with a Victron 100|20. I haven't watched your fuel polishing video, however the professionals use a high pressure pump to stir up sediment that has settled in the tank as they polish it. Usually it's this sediment that clogs pickups when you get underway in rough seas.
I know its probably late but think for fuel system is design the tank with it angled to a low area and you can install a drain plug to drain off any water that might get in tank. As you know water heavier than the fuel.
We considered it, but the gain was minimal and wasn't worth the cost. Most of the time the underside is blocked by the tender. That, and we got a great deal on our Sunpower Maxion cell panels.
Have you checked to see if your container, when moved closer to the fence, will not violate the set back rules for the city? I'm not sure since it's a temporary structure and may be fine to get closer than the setback requirements, but I would check, just to be sure someone from the city won't show up some day in the middle of the build and hand you a violation.
Here is something interesting about that setback, which I looked up. The business on one side of us has permanent structures only 1' from the fence, and on the other side, the house on that lot has a garage only 1' from the fence next to us. Yet we will actually have 4' of setback for our container, even after we move it over (which is the listed requirement for this city) but our neighbors are all in violation.
I was wondering if your build site is close to the house, to save time on commuting, or closer to where you'll launch, to make it easier on transporting he boat? (avoid freeways, etc.)
Our build site is 2 minutes from our crew's houses. The interesting part of transporting the finished boat is that there isn't much difference in difficulty or cost going 5 miles or 30 miles. The major costs remain about the same (hiring a crane on both ends, hiring a semi with flatbed, paying for a Highway Patrol escort and wide load car support, etc. The biggest hassle is loading, unloading, and the trip from the site to the freeway and same at the other end. The actual portion on the freeway is the easy part and that's where the difference in distance is made up. So, for us, saving almost 3 hours a day in commute would be far more costly. And we aren't talking about the gas, it's the time we would lose working on the boat. It would extend our build time by around 2.5 years! We would lose about 4,500 man hours of work time driving over two years (3 people x 3 hours a day sitting in LA traffic, x 500 days), then another 4,500 hours because we had to extend the build time by 2.5 years. I would rather have one day where we have to drive an extra hour on the freeway at 3 am to transport the boat the extra 25 miles than add 2.5 years to the build time. It is also just nice to have our houses so close for when we need to run back to get something (like more epoxy, since we can't store it on the lot. It gets too hot in the summer to keep $25,000 worth of epoxy in the shipping container where it would go bad in the heat.) Alternatively, we could have rented a place to stay down by the build site near the beach, but that adds $50,000 (minimum) to the cost. So, by building near our houses, we save 2.5 years or $50,000, take your pick :)
wait a minute. If you are using DC breakers for solar you need both positive and negative to have a breaker. Even then you are still at risk of fire. if it trips the breaker and you only have it on positive 5 amps can start a fire and if the negative doesn't trip a fire happens. The reason is the gap on those breakers are small and DC current can jump it and continue to arc. Watch videos on RU-vid it shows this and how a couple people lost their solar equipment. I use inline fuse on my panels and a disconnect switch that has a much much larger gap so DC can not jump it. I have 391 volts max per wire going to disconnect with 16 amps max. My disconnect can handle 1000 volts with 64 amps. from each series of panels I have a 10 amp inline fuse before I join them together ( my series amps are 8 max) then run them to disconnect switch then to each inverter. you would connect to each charge controller which means you will need more disconnect switches and not rated as high as mine since you are not running the DC voltage amount that I am. The disconnect switch does both Pos and Neg at same time so arcing will not happen. I really do not want to see your equipment or boat burnt up.
Thanks for the input, but we don't have that much voltage or amps per wire in our system. The absolute max of 86 volts (mostly less) and 5 amps maximum per wire. I will have my electrician look it all over and recommend what we need. One of my friends has owned Competition Electric for 30 years, so he knows what he's doing. If we need to add inline fuses, etc., we will.
Just curious... why an individual MPPT for each panel? I would expect you would be able to just have a 2-3 zones to handle shading issues. It would be way less wiring, and I think it would also be more efficient to run at a higher voltage.
We covered that in the video, check at the 8:48 minute mark. When we show the shot of the boat with shadows, notice the one from the boom hitting the center panel of the stern array. If we had grouped those, that one panel would then affect the others, just a good example.
@@SailingSVLynx my apologies for missing it. I must have literally ignored the video RIGHT at that point because I was busy furiously composing my comment. LOL. Keep the vids coming!
And with it, we're still under the LCC for S/V Lynx with everything we plan to put on board. (adding to my response) We reduced weight by going to synthetic rigging and our Parallel Hybrid propulsion system is lighter than the 2 diesel engines in the normal dry weight configuration of the 1490. All total, those savings are about the same weight as the solar panels we added. Now, we did add some additional weight in lithium batteries, but even with those we are still under the LCC Schionning lists for this cat.
