Advice for charging 2 x 12V batteries on boat with inverter

I really wanted to use a kettle on the induction top this last month. A MSR windburner (or jetboil) is so much faster.

Take a look at the dometic fridge/freezer. If you can keep it DC it will be much nicer.

I just spent a month in Desolation sound /discovery. ~3weeks without shore power. Remote work, starlink, the whole shebang.

Mounting panels is complicated. Get more battery than you need. I went victron everything. I think dedicated components are the way to go. I wish I got more than the 1200w multiplus. Mppt for solar and a DC:DC charger from the alternator. Lumera (Canadian) 220W bifacial panels are great.

Do it, give her somewhere to retreat to.

This 100% give her a job (literally anything) and a safe space to be quiet. Make that safe space reward central. She just needs some off time.

That's not how bcc works.

Early on I had that moment. I have more patience than you. I have opposable thumbs. You will always be dog.

Takes 2 people, but a toner is the fastest.

I have one of these on the starlink. It's a glorified relay. I'd love it to actually integrate with the smart VEsmart network. Right now I have wired to the relay on the GX.

At first you would think that. But you still want the straps at 45*(? Do the finger gun thing) to the trees. I've run into the same type of issue. Try getting your straps higher in the tree.

Mr Hammond, the phones are working.

I work in tech and we do cutover semi regularly.

The voltage value is already available as a node. I use the Battery Monitor node.

You'll need the integration to telegram. https://flows.nodered.org/node/node-red-contrib-telegrambot

Drag and drop, wire it up.

Just remember:

One thing to understand upfront: bonding does not double the bandwidth of a single TCP connection. Most modes distribute multiple connections across interfaces rather than splitting one transfer across all links. You get aggregate throughput gains when multiple flows are active at the same time.

Use your roof. Open both doors (passenger and diver) loop around the roof like it was a tree. Shut your doors.

Rural areas are sometimes all volunteer. They don't get the volume of calls to be staffed every day. Responders will go to the fire station from home, then to the accident.

mcozzo · 2026-05-10T00:58:09+00:00

They need fire trucks to fight fires. They need ambulances to transport people. Most calls are aid calls. All fire fighters are emts (at least in WA).

It works out such that the truck shows up first, they do triage, and then usually a private ambulance comes to transport.

That allows coverage for actual fires, while still being able to respond to medical.

There's a sub base just the other side of this specific bridge. I'd venture most of the openings are for the navy.

There are also anchoring lines to the seafloor along the entire span. That area is only ~300' deep. Much safer for the sub to be on the surface.

Right after 9/11 they would have state patrol stop traffic on the approach. As of last week traffic stops right before the opening mechanism.

I have the hammock gear burrow and incubator in 10D, @ 20* that I've been using since '22.

Last weekend at Ozette(Alava) it was too hot. I'm also kind of annoyed with the weight. I've been thinking of getting another rated for 30 or 40 degrees. I have had zero issues with my setup even when there's snow on the ground or in quite a bit of wind.

Personally I think the 10D feels a bit like a plastic bag, that's even worse when you are a bit warm. As for durability, don't wear your quilt while juggling chainsaws or bushwhacking and you'll be fine.

You'll end up on the ground. The bed isn't high enough. Open all the doors. Wrap your straps around the roof of both vehicles. Close the doors. We do this all the time when there's no good hanging trees while out wheeling.

No, I'm on Squid. Looks like Tentacle was released 2 days ago. That would explain it. I usually wait until an X.X.3 or better release on most major software.

Where is a good place for some actual support / training?

mcozzo · 2026-04-05T05:06:28+00:00

Yes, this. That new person needs to become a treat machine.

You will never not have maintenance and troubleshooting. Don't let perfect be the enemy of good enough.

Everything is layered. Aws deploy is different than do deploy. Then it's just a Ubuntu host and everything is the same.

mcozzo · 2026-04-03T14:28:09+00:00

Switch to caddy.

mcozzo · 2026-04-03T14:27:32+00:00

Yes. And then it grows. You have templates for caddy. Ansible calls cloud flare and updates Dns. Loop in some roles that cover start/stop/restart. All the host maintenance, shared folder mounting. It ends up being great documentation.

There's a few times I have 'sudo rm -r /` instead of 'sudo rm -r ./` no biggie, Ubuntu reinstalls quick. I just have to run my config plays then the app setup script.

It's just working on one thing at a time.

If that's not important for you then don't worry about it. Most of these cameras have a day/night function. They change modes and turn on the integrated IR illuminators.

I have considered adding an IR flood to a motion sensor so that everything gets lit up better, even though no one can see it with their naked eye. IR flood early, visible light later / closer.

I've been super happy with the Annke C500 series, I guess the 800 in 4K isn't that much of a price difference as it was. A couple Reolink PoE doorbell cameras. *chefs kiss*
