I think you've got that backwards

Crew brings beer for themselves and everyone else, captain brings the boat and sandwiches (regular crew should expect to do 1-2 work days per season at the beginning/end of the season, pick your own definition of regular crew, plus half a work day (+ or more) for travel regatta)

If you go home with glass or a trophy, then rum payment is involved. Captain always buys the crew a round at the bar after every regatta no matter what

That said, all my crew moved away due to covid, I'm looking for bay area crew soonish, probably Wednesday or Friday night beercan races

48 volts, lifepo4 batteries, check out "Sailing Uma" (e;fb :v: ), especially the later videos. diysolarforum has some info on what aliexpress sellers are good for batteries, and who to absolutely avoid.

Do your research before buying batteries, DO NOT buy the "first and best" cells you find, and build your own pack unless you love pissing away money.

You can build a reasonable battery bank with 272/280 Ah lifepo4 cells, a 16s pack of those give you 14 kWh raw capacity, 12 kWh usable if you want them to last, peak power output is 1C, so about 13-14kW over a fair amount of the SOC range. You'll need a contactor-based BMS, and a good charger setup for lithium.

Keep your old 12V/24V system for navigation and lights, use a DC-DC charger from the 48V system. There are some caveats for solar with a 48V battery bank, in that most MPPT controllers are buck, not boost, so you need a Voc at least 5V above your battery voltage, that means multiple panels in series, that can get annoying.

There's an alarming number of electric sailboat groups on Facebook. A lot of people get burned buying "CALB" batteries from some fly by night Alibaba supplier. Good luck. As with all things in this industry, you get what you pay for

Lifepo4 batteries have really dropped in price recently, so that's a plus

well I do have 34 310ah cells coming in and will be running a 48v system for the motor, already spent 5 months poking at this but i was more looking for the configs on the motor controller the other dude used. I am going to be using a HPEVS ac34x2 and that can suck down some amps. So the 2x 16s may not provide enough amps and may need a third bank.

As for solar I am going to be doing 2x 48v solar panels in series to start each panel doing 410+ watts.

Well those seem like a pain in butt and Daly bms once you update the firmware aren't terrible and can do 300a. But if you can suggest one i am open to looking at them.

Its going to be 2 different 300amp banks. with 3/0 gauge wire running to 2x Victron Energy Lynx 1000amp Distributors. One of these will just be for battery the other one that is hooked up will be for the motor controllers and invertor/charger.

I mean I got the hot water working but that is because my deck shower in the cockpit had a lovely o ring on hot water side and didn't pressurize the system just dumped water into the blige. But the wiring is also boned as hell on the 120v side which will be fixed when I install the invertor/charger.

Right now i just dropped 4.5k on batteries but up next is the BMS and Invertor/charger on buy list along with wiring stuff.

I've also been considering moving to LFP, but just for my house bank, and in my case I think 12V 100 Ah will be sort of overkill. :v: That's like 1.3 kWh, and my daily consumption is typically around 200 Wh or maybe a bit more. For such a small bank the BMS and the DC-DC charger will cost more than the cells will (including shipping). Just having a hard time choosing a BMS; Daly seems okay but even their smallest models are kind of big and expensive for my needs. Overkill is a lot cheaper but I can't find it for sale in the EU. GWL's BMS123 Smart seems really nice, nicer than Daly and also takes less space (modules attached directly to the cell terminals) but again pretty expensive. Victron's got some really nice integrated solutions that are both BMS and DC-DC charger in one, but they only work with their own batteries.

For DC-DC charging though Victron does have some pretty attractive options; their Orion things seems like just the ticket.

Two banks is good, that gives you some redundancy if one BMS trips out, as well as 600A sustained and probably 1200A short-term current capability depending on the cells you pick. I would avoid a FET-based BMS, I'll see if I can find a decent contactor-based one, but they do cost a bit.

Victron makes solid gear, I always recommend them first, I'm a bit more leery about using an all in one for a boat, though. With 40+Voc solar panels, you will want an MPPT that can do 120V, so you have some headroom.

If you intend on keeping the boat for a long time, going LFP might not be a bad idea, I would consider going for a larger battery, too, it doesn't cost all that much more if you're already going to build it yourself.

But with that sort of power budget, a decent deep cycle 100-150 Ah lead acid battery would probably do the trick, too.

How are you mounting those panels?

Be mindful of the voltage ranges for the MPPT, the 6048 starts at 120V, that's 3 of those panels in full sun in series before it even starts charging, as soon as you get any shading it'll drop off to 0.
Buy one of the all-in-ones for grid charging and inverter duties, but hook the panels up to a Victron 100/20-48, it's actually pretty reasonably priced.

Not mounting anytime soon but going to get an arch built.

Also i have seen/heard that the 100v mppt from victron has been doing alot of RMA's and the 150v are the go to.

good catch on the min voltage, So it is looking like growatt is the go to even if its only 3kw

or
2500 + 150
https://www.altestore.com/store/inv...E#VICQUAT485000


don't get me wrong victron is awesome, just pricey when you have other actors pulling down the price hard, and not making a terrible product.

I hadn't heard those 100/20 models had a lot of RMA's, but it wouldn't surprise me - they're in that iffy area where you can hit overvoltage real easy if you're not very careful with panel selection.

I'd go for the growatt, then, it seems to fit the bill.

And you don't have to run all Victron. If you had to get that IP67 MPP solar all in one, you could combine it with a Victron MPPT to get the voltage range you want for the solar panels.

Can you turn off the inverter on the growatt? so only the solar charger is active? If not, I would get a separate MPPT regardless.

Think so you can turn off the inverter or do something in the setting, I do see the stand by power for the invertors talked about is 28w. I may also go beyond 2 panels because going all electric has nice power demands.

other progress, bump stop for the steering got pulled because its a rusty scaly mess, and i need to figure out a fab to make it in aluminium 6061 or 6063.

I just read the manual, and you can, so that's good!

800W of solar will probably not be enough, that's fair. At the same time you don't really have a lot of convenient places to put large 60/72-cell solar panels on a monohull, so you might have to resort to a separate boost MPPT charge controller. This might be suitable.

I'm almost certainly in it for the long haul with this boat, it's perfect for the sailing we do and there's not really any alternatives, but realistically the reason to do LFP is more because it's a fun DIY project than because it's necessary. The reputable seller I'm looking at on Alibaba doesn't have anything in between 100Ah and 272 Ah though, at least not in stock at the moment. I can easily afford 272 Ah, and probably fit it in the battery compartment too, but it'd just be comically huge for my needs - like what on earth would I do with 3.5kWh, run a vacuum cleaner?! With a bank like that I'd barely have to charge at all for an entire vacation trip (we usually stay out 2-3 weeks at a time), but on the other hand charging it to full would be a pain in the rear end - we have no shore power, a lovely alternator and not a ton of solar.

wargames posted:

No, the plan would be to keep the lead-acid start battery and charge that with the alternator, then use a DC-DC charger to charge the LFP bank from that. My engine is original from when the boat was built in 1979 - it's the venerable Volvo Penta MD7A. It made a whopping 13.5 horsepower brand new, and while I recently replaced the alternator, the replacement is still only 45A nominal, and I'm like 95% sure even a 100Ah LFP bank could make that thing overheat in ten minutes flat if I just hooked it up (it doesn't help that engine compartment ventilation isn't exactly great on these old boats). I need some kind of current limiting for charging via the alternator and a DC-DC charger seems like a good way to do that.
