- In this video I go through how much power we generate daily on SV Delos, where it comes from, and how our generator time has gone down by 30% after installing Lithium batteries!
Topics in this video are:
How much power do we generate on a daily basis from solar on a sailboat?
How much power do we generate from wind on a sailboat?
How noisy are wind generators?
How much does a wind generator make?
Are Lithium batteries more efficient at charging?
What is the percentages of power from all sources?
Did the generator time go up or down after installing the new Lithium batteries?

As an engineer and sailor myself, this episode was like crack. :)
Be myself a Electromechanic, technical information was really interesting!!! :-) :-)
🤪🤣🤪🤣🤪
Keeping an electrical system functioning in a marine environment as opposed to land based application is tricky.
Bravo to Delos crew for keeping everything humming along..
You are using about 1/6 the electricity per day that I am using at my house.
This is an 80+ acre property with 3 barns and irrigation.
Of course I am running electric water heater, stove, clothes dryer, pool pump, four well pumps that are all 240v.
I have converted my workshop to off grid solar as it is an ideal setup because I use it intermittently.
200w solar with 2 lead acid batteries and a 3000 w inverter.
I can run lights and most power tools since they are not being run for a long time period.
Great video.
Brian fixing stuff and his tech info is why I got "hooked on Delos" years ago!!!
Hi Guys. Thanks a for sharing your lives with us,. I sail a Dufour 39 around the Baleares Islands and the Costa Brava. I find your tips incredibly useful, and the way that Brian explains everything is really easy to understand. I have just listened to the episode on electricity consumption, wind and solar generators 12 to 24V which Brian and Brady put together and it has been enlightening, if you pardon the pun. Good luck wherever you are now.
Been watching for years abd this is one of the most informative videos you have ever made. Here is a summary of electrical consumption in Sidney BC, Our "standby" consumption for two families in 2400 sq feet is abour 10 kwh per day. We have the convenience of looking at our consumption on and hourly basis, and in the wee small hours of the morning it is about 0.4 kw per hour. During this time the only things turned on are 2 fridges, one freezer, about 6 clocks, (they seem to be everywhere) internet and cableTV connections. During the daytime the biggest users are clothes dryer 3kw and elevtric conventional oven 4kw. annually we use about 700 kwh total. We have no electric heat. No A/C. (all natural gas)
You are right on with your numbers.
Brian, you are so good at explainning everything. I know some might feel overwhelmed by data analyst(you being an engineer) but I just love listening to your clear, crisp voice explaining sophisticated systems we can all understand. Please make more of these. They are great and create a good balance with the beautiful photography and videos that you guys publish every week.
I just went on a sailing trip with my buds and the electrical systems where the second most concerning thing we faced... Second to dragging anchor when the wind got gnarly at night. This vid was really awesome! I think for newer cruisers/aspiring cruisers like myself, a video on feeling secure with anchoring in new locations would be pretty cool too. My main issue was not knowing exactly how deep we were and not knowing how much anchor chain I was spitting out per second. I digress.... My buddy and I both looked at our electric bill to see what we use per day to get a good feel for what a kwh means to us! You guys/girls inspire me and educate me every week. I really really really appreciate it. I like the educational videos because I plan cross an ocean one day too. We have a little music vid we are working on from our trip. I didn't take the Delos shirt off the entire time!! Much love!
you guys made me planning to buy my own sailboat and travel from Europe to the Caribbean. at this moment I am just soaking up all the information I need and learn every bit of information thats available. these types of videos are like pure solid gold for me. please continue Brian doing these kinds of videos.
Another great video. One thing many get hung up on is comparing the 12V to 24V(DC) and then 110 & 220(AC). Explaining the commonality of these in watts or KWh is helpful. BTW, I fully and 100% blame you guys for the position I’m in. You guys made us quit everything. Waiting on the last assets to sell and boat shopping for full time cruising very soon. Hope to meet you out there one day!
Right on Jason! Congrats and so happy for you. yeah, boat stuff is kind of messy because the old-school DC stuff is in AH. But if you just remember P=IxE (power = current x voltage) it pretty much applies to anything. Good ole' Ohm's law to the rescue.
Way to go man. Living the dream not dreaming the life!!!
Chris T Thank you sir. It’s been a hell of a process to get here but my wife and I are pretty stoked
Same here :-( ;-) Sold house etc. bought Lagoon 420 :-)
pvdneste wanna sell that 420? Lol
dude absolutely loving this new series on the board electrical. extremely helpful and i love the way Brian breaks things down into a no nonsense explanation. this series will be an excellent reference for me for future use.
Two days in a row!!! Wow😆 never get tired of seeing y'all 😍
Perfect timing for these videos. I recently bought a boat after selling up, and now after 3 weeks of scraping, sanding, and painting I am about to start on electronics. The boat already has solar and MPPT controller, just upgraded battery bank to AGM(lithium was not in budget). I didn't know the MPPT had bluetooth until seeing your video. I'm sure I would have eventually figured it out, but thanks for the info. The inverter that came in it is a Trace engineering U2512 2.5kw from 1993. It works fine but I wonder if upgrading to a newer one would be more efficient. And I agree with Jason Ensminger, I blame you, UA-cam, and all the other sailing channels for making videos of people living the dream. Hope to buy you a beer one day, or maybe you could buy me one. I might be out of money by then.
These videos are excellent info for people that are looking to get into sailing and need this type of info for future upgrades. Thanks and love e videos what a crazy awesome adventure of a life. Can't wait to meet the little one!
Like seeing the other side of sailing. Not just the nice places you go... That is why this is one of the best channels out there. Great job.
Brian, really liking these vids. It's both giving me ideas as well as verifying what I have planned. Cheers!
This is truly valuable data! Brian, it's great to hear someone that's at instructor level sailing as captain then willing to share his info. You're intelligent and it's refreshing. I feel smarter after watching this informative video and I want to thank you for that.
Great info, we just stepped up from our 26' Seafarer to an older 35' Intrepid and we're starting the refit for living aboard in a year or two. These videos are hugely helpful.
Yesss!!! Moar tech vids!
I'm in the middle of completely restoring a 1963 cruising boat. Redoing everything from the glass up. I gotta tell ya, these Boat Bits are incredibly helpful in my planning processes. Thank you!
Please keep making these videos. I am currently working on restoring a 1963 43' Stephens Flush-deck motor-yacht with plans to sell it shortly after restoration to purchase a cruising cat, or build a Wharram, and live aboard sailing the world, so these videos are very significant to me personally, as I have my head in boat-work and systems almost every day, and the real world insight you bring to the topics is invaluable. I have been watching Delos since Australia, and it's no understatement to say the inspiration you have brought me literally changed the course of my life.
No one else is covering this material as well as you are. This is really valuable. You will be a resource for millions with these videos. You have the perfect system to showcase the various elements that apply to most mobile electrical systems.
Most technical information is still in books when it comes to sailing. The information that is online is usually entertainment and heresay. It’s no surprise that Delos nailed it, they always do. Best sailing vids around! Thanks guys!
Super content guys. I love hearing about the reasons behind why you have done what you did. Not to mention how it all worked out after the install. We have all wrestled with decisions like this whether on a sailboat or not and being part of the process (even from afar) is really helpful.
Just the very best sailing cruiser channel since the beginning. Great people, lots of good well explained information. Great adventures and a great boat. Life will be very different from the moment the baby will enter your lifes. It will determain the rithm of the days. Lot's of spontanious things will not work any more. But please do not get over protective. It is important to give the baby sort of rithm and a bit of comfort and rest. But when the baby is used to sounds it will not get disturbed by them. By that I mean that when it is going to bed do not try to stop making sounds. And start to whisper etc. Just play your music and have conversations etc. It will make life much easier and more enjoyable. Thanks for the effort of making these video's and welcome to the new chapter. Kids are hard work but at the same time the best there is.
Future cruiser here.. love the info you pack into your video.. from Q&A like this to onboard repairs... Thank You..
I love these videos! My education was in electrical engineering, but I've been out of that field for decades. So that makes these fun for me.
3 years old and still relevant! Thanks Brian.
Another great video on your power generation and consumption!
These tech videos are valuable to me. I must admit, I haven't learnt much from them but what I believe to know has been confirmed. Brian does a great job explaining things, I think he was a teacher in a past life lol.
Delos system design and tech tips are great. I love the repair and maintenance videos as well. It’s the magic behind “the self sustaining life” you live and we admire.
This series is a huge help to me. I will retire in 2 years, we are buying a bigger boat that will eventually end up in South East Asia. The sweet spot in efficiency is becoming much more clear.
Brian, I looked up my electric bill and I consume between 500-700KW per month, which is about 16-23kw per day. So I guess that is about 3-4 times what you use on the boat. I am single and live in an 1800 sq ft home in the USA (NC) with most of my electric being consumed by the Central AC/Heat I suspect. GREAT Video guys! Like the Brian Bits!
I looked also. my house is
@@seafever8644 Just for another comparison. In QLD Australia, House is around 2000sft. Have 2x Fridges, Freezer, Pool. Air conditioner gets used when needed, it's quite hot here. Average for us here would be around 15kwh a day average. We pay roughly 28c / kWh here. 2 Adults, 2 kids. Most of the bill goes towards the pool + electric stove/oven. And cooling when we use it.
We are a family of 4 in a detached home of about 3500 Sqft in Canada and run about 450KWh\month (13.3\d) with a low of 300 and a high of 600\m. Sorry Australia but our power rates are 6.8 cents\KWh. Much of our energy usage though is for heat which comes in the form of Natural gas which isn't included in these numbers.
1600 sq. Ft. Single family, 2 people with fridge, freezer, basic lights, computers, little TV, extra power WiFi, electric stove, our own well, propane hot water, ~300 kwh/mo. $0.115/kwh but more than 80% by solar. The 300kWh is before solar generation.
Brian and crew- we're really liking the tech video aspect combined with real world data from someone doing it. It doesn't get any more real than that. Thanks!
I was an sailor for 17 years . We said that boat life is an miniture society. Allways looking forward to watch an episode in the evening. Keep it up like it a lot :) best from sailorbear
Absolutely loving the technical reviews and operations of the Delos systems. Super information, keep these types of vids coming!! Thanks!
Brian does a great job as boat nerd! This stuff is super interesting Brian, and you put it in terms that most people can understand! Great job!
I honestly wasn’t going to watch the first one because I figured I wouldn’t understand it. I did anyway because Brian is awesome at communicating and explaining technical issues. Future Patron soon and I look forward to meeting you guys on Delos in the near future. Because of you I found out sailing is possible for almost anyone. I would have never of thought otherwise. Thank You!!!
Amazing explanations of the systems. I love seeing how detailed Brian's knowledge is of the boat.
My 4000 sq-ft house in Texas used 3325 kWh in the heat of the summer this past July with a pretty high electricity demand for air conditioning. That was a little over 100 kWh per day. This past October it dropped to 1825 kWh with cooler weather which is about half of what we used in July. This was really interesting and informative. Thanks Brian & Brady!
Been working on getting my Wife on board (no pun intended) about living on a boat part of the year, or full time if it was up to me. Anyway she is a very smart factual type. The more information I know, I can combat alot of her concerns. Anyway i said all that to say the last few episodes have help me tremendously. Thanks y'all
My first comment... I’m really glad you’re doing this series as I’m saving for a cat in the next 4 years and casting the lines. These are teaching me so much about how I want to set up my boat once I have her.
Thank you so much
Tim
So excited to see this is going to be a 7-part series!!
Great information! My boat, SV MeiHua, gets nearly all its power from our solar panels and
I had no idea how much more efficient lithium batteries were. Than you for the in depth instruction.
Just wait till you see how much more expensive they are :)
If serious first time sailboat buyers are not watching and making notes , then shame on them. This info can't
be found elsewhere. Thank you for the effort to keep logs etc etc. Great videos , thank you.
Your boat is really dialed in nicely. The lithium batteries and electric stove/oven are probably the future for all boats. No more propane! You could almost get away with not needing a generator at all
This series is awesome. I'm just getting started outfitting my boat with solar as an electrical neophyte. I was going to have it done for me but the quotes I got for solar, lithium batteries, and a new charge controller were in the $15K range -- more than I wanted to spend. Educating myself so I can do it on my own will not only save a lot of $$$, but I'll know how to troubleshoot it and continue to upgrade it as time goes on (i.e. bimini solar, wind, hydro, etc.) or for the next boat.
Finally a boater that knows the difference between power and energy! Kudos for educating the public too.
Brian, you are such a biscuit! I have learned so much from your channel - thank you! You are a legend!
These tech videos have really been interesting and a terrific asset to folks planning their boat purchases and upgrades. Thanks Captain.
Always appreciate the awesome advice and knowledge you share! Love the fact that you do your research and put alot of thought into your own setup and then share your knowledge of it! Please keep it up! Definitely on the right track!! Hope to see you guys out there someday soon! 😁
Great info guys ! Thanks for answering my question, looks like I’ll be going in that direction on my boat. As always love the tech videos
I received my Duke Energy bill this morning before watching this video. For October, when there wasn't much if any AC running in the house and we have gas heat. Our house is about 2300 ft^2, 2 stories and it is my wife and I and our newborn. We have an electric water heater, and mostly LED lights everywhere in the house. We used 796 kWh over the 29 days or 27 kWh/day. In July when the AC was pumping since we had one of our hottest month's ever, we used 78 kWh/day...
loved this one. i was very curious how your numbers looked compared to our cat. and i like that you drilled down in to the numbers and did not gloss over the details. and ya we got rid of both our wind generators. the noise and shadow on our big solar bank just made them annoying. much happier without them. and got a good price for them. dont miss them at all
Have always loved your videos. Soon to be living onboard a cruising sailboat, these are great lessons learned in a simple way.
Yes i like the content. One or two questions at a time and covering each topic thoroughly.
Brian I love watching your “diy” episodes I have learned a lot watching your channel. Keep it up!
Thank you so much for sharing. I have done some similar Solar project with my land yacht (RV). I love comparing notes. Some of my biggest mistake have been calculating amps. This is because half of the RV is on 12v system and the other half is 120v. Let's just say my AC run time turned out to be a lot shorter than originally planned.
Brian, your passion for tech almost reignites my own interest, ... almost. 😊 although I enjoy watching others getting passionate about it all.
Just a note on flexible solar panels, a fellow UA-camr did an interview where they discussed his use of the flexible panels and he had to mount them on a sheet of Lexan. Apparently the panels got very hot to the touch and it effected to the output. By mounting them on the Lexan sheets, air was allowed to flow under the panels. The panels remained cool to the touch and energy output was much better.
The fellow UA-camr's name was Nick O'Kelly and I think the title was "Top secret boat tour", or some such.
Safe sailing and stay well!

Another excellent video. I live for the technical videos. It really rounds out the channel giving a nice balance of sailing, touring, exploring and technical.
A different boat, but it is interesting how far Uma has taken things. I really enjoy both your channels. You both put a lot of work into your boats. You both are so down to earth. You both also do a great job creating your videos.
Your figures almost exactly confirm my own observations in my Amel. What I had not apreciated before I saw your video was the beneficial effect of LiFe batteries.
Very interesting. Thanks
Great series and explanations in plain English. Helping to make decisions on my own boat.
Loving this series!!! Its great information for someone like me who is planning on buying a sailboat very little experience in these matters.
Everyone does the high level info type videos... its great you are getting deep in the weeds and nerding out for the people who search for this kind of stuff. Good effort!
Love the in depth discussion! Keep em coming!
If you do decide to try the thin flexible film solar route, videos of the install... and heck even the debate on how and where you decide to do the install would be of interest! The thought process you go though is quite educational.
ive watched a ton of these videos in no discernable order this is one of the most interesting ..much love to these dudes..Hey from PHX😎
Thank you for the technology updates, these are great videos for us tech geek sailors. Having studied some energy engineering back in the 90's, this was interesting to see.
Boat owners should always have an up to date wiring diagram of their boat. 95 percent of boaters do not have one, but having done a few re-wiring and installation jobs, I can appreciate a diagram of the existing system.
in the 80's my father bought a beautiful wooden powerboat (36 ft traditional Finnish fishing boat, displacement hull, built 1976). The original owner was an electrical engineer by profession, and he did not have any wiring diagram, or any other documentation of the wiring. There were lots of weird electrical connections: when turning the engine room fan on, the navigation lights had a dim glow, etc.
I think you should try to make Delos 2.0 a carbon-neutral yacht, using only renewable energy (solar and wind) while at anchor. This should be possible with some optimization.
You might want to forget the diesel main engine altogether, and have an electric propulsion motor. It would allow motoring short distances without using diesel fuel at all. (Entering anchorages/marinas etc). When you need more power (or for a longer time) than what the solar/batteries can provide, two smaller diesel generators (probably one larger and one smaller for power reserve) would be far more effective than one large main diesel engine. Smaller generators could always be run at the most effective RPM, having much better power/fuel consumption ratio than running the main engine.
love these how-to/ tech vids
I’m going offshore next year and need a more efficient electrical system. This stuff is gold!
Same here, I agree.
The new videos have been interesting to watch and informative. I'm getting ready to redo the electrical this winter on my boat here in Lake Michigan and although the systems aren't the same the concepts and products transfer to my project. Thanks, Crew!
Love this series guys. Very helpful and informative. Keep up all the great work. Much love. ❤
Dude just watching you explain these things i can't help but think you are going to be such a good dad!!!
The electrical info is great and you're doing an excellent of making relatively understandable. I'm not sure why but I like your maintenance videos, but I do find them interesting. This is going back awhile, but your replacement of Delos's standing rigging was really interesting as well. I've enjoyed sailing vicariously through you guys! Be safe, be well and I hope all goes well in future events!
love the technical/maintenance side of your lifestyle.
I have to admit that I'm envious of your solar and wind generators. I have to run my generator at least 4-6 hours a day to keep my batteries charged right now.
You are definitely on track with these videos. EXCELLENT. Thank you so much for sharing.
This video series is outstanding! Looking forward to the next ones.
I really like the videos you are doing about the workings of Delos. Thanks for sharing!
Fantastic video, well explained and really helps the rest of us understand how having all three options (Solar, Wind, and Generator) help to keep power available and ready anytime of day or night.
As an aircraft mechanic i always love the technical topics.
Watched your video yesterday, simply put excellent!!!! Looking forward to watching this one.
Great information that you guys have passed on in this video. Delos may be an older vessel but she is state of the art when it comes to her electric systems. I'm glad to know that the Lithium ion battery experiment is working out well. I may go that way soon on my boat. On a different subject, since you guys are out cruising you probably don't drive cars too much, but fully electric cars are so cool. We've now had two of them and they are like magic. Best regards, John Fradkin, s/v Deerfoot
Nice to hear the results from the upgrades!
These videos are great! I wish I had a Brian in my life as I tackle the electrical projects on my boat. I'll be sitting in the marina this weekend watching UA-cam and reading a book for Dummies.
Thanks for the clear response on noisy wind generators.
Great topic as I had seen before but looking for a wind generator now and wanted go back and find this one for reference. Mainly looking for quite one lol. Thanks and you guys stay safe out there...
Love these tech vids. As a sailor myself they are so interesting, and Brian your slightly nerdy approach (!!) to record keeping is just brilliant when it comes to explaining how it all works. Keep these great vids coming. I,m putting 270W on my arch at the moment and when I can I shall upgrade to Li batteries on the strength of this video. Thanks
The descriptions are extremely clear, so electrical luddites find it easy to understand. You should have been a teacher, Brian. Oh wait, you've been teaching sailors for years. Cheers.
Sing along the intro song:
”I’m dancing
I’m licking on Bolerom sause
I couldn’t see my leg
I couldn’t see my leg
My leg”
😂😂😂
Thank you guys for shareing your experiences and travels! it keeps our spirits high during this corona crisis and home lockdown. Lots of love from Finland! ❤️❤️❤️
Loving these videos, Brian! Thanks for doing them!
This stuff is always super interesting ....... and useful.
All these electrical videos were very educational! Thank you
I know alot about alternate powers and I still find your entire system very interesting and amazing !!!!!! What an awesome set up !!!!!!.... I have no problem being off the grid !!!!!
Love the tech talk about solar, wind and your set up. Thanks a bunch!
Thank you Brian and Brady for the Videos ,
Another great video Brian. Explained in a clear concise easy to understand way. Thanks for sharing your knowlege to the tribe.
Lots of love from Down Under
❤❤❤❤❤❤❤❤
Most excellent video. Thanks. I’m trying to size an electrical power system for my boat upgrade. Around 1000 watts to 1200 watts of solar power seems to be the consensus of those boaters who make UA-cam videos. Yours, at around 900 watts is very comparable. It’s really nice to know that about 70% of your power is made by solar.
