I attended that ABYC instructor's, mentioned at 1:03:19, class in Portland. Very sobering experience understanding that it's not just preventing fires on a boat, or making things work, but also preventing folks (particularly kids) from experiencing dangerous difference in potential around a boat in the marina.
It wasn't mentioned here but some engines actually have a secondary charge cable on the engine specifically for house banks. All Yamaha outboards 150hp+ and 2001+ have a short red cable with a black wire harness connector on the end. You can use this and no need for a combiner or isolator.
Single pole breakers: welcome to Norway. We donta have Live and Neuttal. Our power grid is IT-net with L1 , L2, L3 and ground. L to L is 220V, L to G is 130V on all phases.
@@PacificYachtSystems Because yea.....why would he want to spend any time explaining shit to you.....he's floating on his boat.....ain't got no time for you! Surely...he'll say "go for it"
Jeff, if you have the time(yeah, right...): I have an 80A alternator and two battery banks; Engine battery and house. My house consumption is about 100Ah, and the house bank will consist of 2X100Ah AGMs. My question: If I use a battery isolator, can I attach a DC to DC charger for my AGMs after the isolator, or should I use some other device to charge them?
Great seminar ! How about Modern Isolation transformer technology like the ones from Mastervolt that are smaller and lighter, any negatives on these newer Mass GI models ?
Hej Jeff! Great seminar as usual! Just some "stupid" questions.. I will have two battery banks (one engine and two house). If using the Battery Isolator (FET) , where then connect the solar controller/s- right to the House bank ( 2x 100 Watt solar panels with one or two controllers..). '
Great stuff thanks to Jeff and the pys team for helping so many boaties. Is there anything on 2 engine launches? 2 alternator agm house bank fla start and solar. I'm thinking a balmar 2 alternator regulator and a DC to DC charger but would love Jeff's opinion Cheers from New Zealand
@@PacificYachtSystems lol - hoping for more hits.....what a joke. How 'bout just answering this guy's question.....as opposed to making yourself another money vid......wanker
I have no idea how to design electric charging system in my boat. I change the existing because is with old on off switch and one liquid lead battery. I consider to put 2 deep cycle batteries (one start and second house) Duracell AGM. Because the existing alternator can damage these type of batteries also consider to put Victron Energy Orion-Tr DC-DC converter (isolated or no isolated?) for charging the batteries. Also I like to separate starter and house battery with Cyrix-ct Combiner or Argo FET Battery Isolator. The question is the order of components for example: Alternator>Isolator(Combiner?)>Charger for StartBatt and Charger for HomeBatt ; OR ; Alternator>Charger with higher current rate> Isolator(Combiner?)> batteries. Also on Home battery I will have solar panel with MPPT controller. Suggestions please
I am using sealed pb acid batteries for my cranking and windlass and LiFePO4 batteries for my house battery. I will be using a high output alternator and a charger inverter for charging. Should I use a combined or a dc to dc charger to charge the house battery bank from the alternator?
Hi Jeff, VolvoPenta stipulates for my engine a 140ah starting battery, but i am worried because of the space and the handling. Will be still wise to make a battery bank instead combining two 80 ah batteries? Thanks!!!!
I have an isolator on my boat but I didn’t install it. How do you identify if it’s an older diode style? (It’s finned style, looks like a heat sink out of my PC) Is it worth it to upgrade to a type Victron like you recommended?
A diode based battery isolator will have a fins to dissipate the heat generated from the diode. Newer FETs battery isolator were introduced less then 10 years ago.
Great series! I had to subscribe as I'm going through a refit, and electrical, and battery bank upgrades are on the list, and to ABYC code. I know aviation electricity, but not marine electricity so well. I heard of cases of reverse polarity and send stray current and it's scary. I am one of those "drill" pilots you mentioned.
Hey Jeff, great video as always. I have watched most if not all your videos and can't seem to recall anything regarding grounding all AC and DC circuits to the hull of the boat (in my case an aluminum hulled houseboat). All the grounds on my boat are isolated from the boat itself. Is that a bad thing and should I alleviate that situation?
Hi Domenick, yes a charger and alternator can be wired to a single battery isolator. Considering the cost of battery isolators, you might want to have separation between your alternator and charger circuits for redundancy.

Thanks for corroborating Felix, much appreciated! We should all strive to learn from others as much as we can.
I'm loving these videos Jeff. If only we could make them mandatory viewing. I'm a fan!
Thanks Cameron.
Hooray! I've got an isolation transformer. Had to wait for the end of your video the relief that this provides me. :-)
Glad I could help!

One of Jeff's best videos. Thanks

Wow. This is thorough. Thank you.
You're very welcome!
Thanks for putting all this together!
My pleasure!
Awesome series of videos. I could totally use some help designing my boats system. I'm building it all from scratch and not sure where to start
Go for it!

For electric drive, using the kW value on a battery monitor is similar to using the tachometer to determine fuel consumption.
Thanks for the input.

Great series. I think you mean check valve not gate valve on water pipe flow analogy 😉.
You are correct

2 alternator agm house bank fla start and solar. I'm thinking a balmar 2 alternator regulator and a DC to DC charger but would love Jeff's opinion

Great idea for a future video, don't we've addresses this specific setup.

Definitely worth considering, since a DC to DC charger can be configured to any charge curve.

Hi Luis, yep you can combine two 80 AH to make a larger starter battery bank.
What about feeding the windlass from the bow thruster battery bank?
Thanks Jeff

Why can an isolators only be used with an alternator. Could I run my alternator and charger to a bus bar then have that run to an isolator
Hi Domenick, yes a charger and alternator can be wired to a single battery isolator. Considering the cost of battery isolators, you might want to have separation between your alternator and charger circuits for redundancy.
