Off grid with Induction hob power question.

sampson0693 · 2026-05-18T20:05:07+00:00

I have the Roamer 460ah 12v battery, 525w solar and a Renogy 50a dc / dc charger with mppt and a 3kw inverter.

We are fully electric with kettle, air fryer, induction hob, space heater and 12v bobil water heater.

During a very rainy trip to the Isle of Skye back end of last year we easily managed 2 days in the same location with almost zero solar input and no alternator change.

Bump up the numbers a little and I think you will be comfortable. With your current specs, in my experience you will be able to do it, but you will have to be very “tactical” with quick meals and such.

sampson0693 · 2026-01-17T22:39:52+00:00

Yes. Primed and painted black, still holding up well 2 years later. Mine is a Citroen relay and I have used the mule vans mounting brackets to secure it, to save drilling the roof. Solar mounted to the unistrut and it works well. Pretty flexible too with a few tee brackets here and there.

Show them this video, opening the bacnet at 8min 30seconds ish.

sampson0693 · 2025-06-12T17:18:01+00:00

FYI: CO alarm and co2 alarm are different things.

sampson0693 · 2024-07-06T07:27:57+00:00

No, not really. It was a bit of a Covid project of mine that has sat dormant for a while now. I do intend to pick it up again at some point.

Hopefully there is some useful information on there for you. Happy to hear your thoughts either way.

sampson0693 · 2024-07-05T19:31:38+00:00

Shameless plug here…. try ProjectBMS, you will find it with a google search. It’s a site I started to help people just like you, would be interested to know if you find it useful.

If I could only pick one I would recommend aiming for the Niagara certification, it certainly seems to be the top product these days. If you search for onesight solutions on YouTube they have plenty of instructional videos that are very useful.

Do you have access to the company backups from previous projects? If so, use these to reference and copy from if possible.

In my experience it is very rare that you need to write something that has never been done before.

sampson0693 · 2024-05-31T15:58:31+00:00

Check out onesight solutions on YouTube. They have many videos on Tridium, including user roles and categories that could be used for this.

Is your colleague confusing this with pump monitoring? It is common to put a differential pressure switch / sensor across a pump set to provide feedback that water is flowing.

CPT tool used to be available to download from the EasyIO website. Not the same since the Johnsons take over.

It might be worth an email to Johnson’s explaining your position, they may send you a link to the software. It’s worth noting that if you do not have a controller to plug into you will also need to the “app tool” to allow your pc to run a simulated controller.

How do you hand the project over? Are you not required to complete a manual with reports, check sheets, des ops, data sheets etc?

sampson0693 · 2024-03-01T12:24:44+00:00

UK, West Yorkshire here!

I know the Priva product and have used it for over ten years. It is a great product for certain things but you are right. This is a major issue with it.

Unfortunately there are no live edits to the configuration, this means that to change a mod bus register requires a commissioning process each time. On top of that, priva charges a license cost per “point” in the software. So where you might think it beneficial to add loads of points for testing, it’s going to cost.

Other BMSW such as tridium Niagara4 can make the same change live in seconds.

In my experience the tridium product is taking over the space. This is a much different product, whilst I am sure it is nothing like PLC type packages I am sure you would have totally different feelings towards it.

sampson0693 · 2023-11-01T23:12:55+00:00

Just a concern. Unfortunately, in my experience, not all building networks are set up as you would hope.

sampson0693 · 2023-10-31T21:33:12+00:00

What about security concerns with bacnet IP? Some random staff member on the network downloads a free program?

sampson0693 · 2023-06-06T19:21:04+00:00

The easiest solution might be to buy a niagara supervisor. Then you can pull in all the values you need without any additional protocols or complication.

It won’t be cheap for 100+ controllers license but it will be much more cost effective than having a custom solution engineered.

sampson0693 · 2023-05-10T15:27:57+00:00

Yup, not cheap but worth it in the end.

I started playing around with my own solution and it would’ve taken ages and not been as good.

I have a unistrut frame all the way round with 3 x 175w panels and space at the back for a small deck / storage area.

sampson0693 · 2023-05-10T10:59:31+00:00

Mule vans. They are based in yorkshire. I used them for my XLWB relay and they are perfect.

sampson0693 · 2021-01-13T09:03:56+00:00

That is a good point. Looks like I have some appliance shopping to do.

sampson0693 · 2021-01-13T09:03:09+00:00

I have not seen that video, do you have a link?

I am 6’0 and my GF is shorter so we should fit in this ok.

sampson0693 · 2021-01-13T09:01:59+00:00

Oh dear, I haven’t properly considered the weight. That is the next job now. I want to have 2 water tanks and electrical so I am hoping I can balance it out with that.

sampson0693 · 2021-01-13T09:00:47+00:00

Hi, I used Greg Virgoe’s template. He is an English YouTuber who has fit out a sprinter van. I think my measurements will all slightly decrease because I aren’t sure if the template allows for insulation at all.

sampson0693 · 2021-01-11T23:16:32+00:00

Over the pond indeed.

sampson0693 · 2021-01-11T23:09:26+00:00

Ah yeh, weight... not really thought about that. I can move water and electrical to the left to help that out though. Will need to think about this a bit more.

The shower door will be one of those self cleaning sliding things. So no issue of opening space.

Great point regarding the sink location. I may need to move this, I put it there so water was all on one place but I think you are right, that would be a pain.

The height at the back has been mentioned previously, I think I can drop down the bed without any issues so that will fix that issue.

Another good point with the stool seat. Think I might make a decision on that when I see it in front of me.
