I totally agree 😍

Thanks for the comment. These units have a very small terminal size built in and as such the unit can really only take a 6mm2 or 8b&s cable. They really are designed to be mounted as closely as possible to the battery.

Thanks for the comment. Yes there is a lot of misinterpretation (or just general making things up) out there from lots of content creators in particular. Hopefully we kept it simple enough for the lay to understand an overall requirement. As with every standard there are a lot of intricacies that are tied into not only this standard but others which are referenced such as the Wiring Rules AS/NZS3000:2018. The standard doesn’t specify fuse type. It specifies circuit protection and under what circumstances. It’s up to the electrician to determine the type that’s required. In this case the blade fuse is fine as the panels used have a VOC of 24V DC which is well within the specifications of the blade fuses used. There is also no specific requirement within the standard for isolator type. Again however, the installer should choose the most appropriate for the installation. If the PV voltage was higher, say 48v dc or above, then the types of circuit protection and isolation used in this particular installation would no longer be appropriate. With regards to RCD/RVD protection, the standard is quite clear in its requirement. There is no requirement in the standard for an RVD (in either 3001 or 3000) however, if the installer deemed it appropriate then they would be able to install the type of RVD that allowed for an MEN connection as that is definitely specified in the standard. To answer your last question, as we are electrical contractors, all of our installations come with an electrical safety certificate which is relevant for the installation that has take place. In our opinion, all installations of this nature should be also supplied with the same. However, as we know, this is not always the case as a lot of installations are undertaken by installers that are not licenced electricians/contractors. Cheers.

Hi and thanks for watching and commenting. We totally agree. More solar the better. But there are always restrictions with RV’s in terms of roof layout and weight that we also need to take into consideration. Plus our winters in Australia are nothing like your winters in North America. We still get solar production through albeit a significantly reduced amount. Cheers.

Thanks for the great feedback

Hi Lorelle thanks for watching and commenting. Generally, to change from a 2000w to a 3000w inverter you would definitely as a minimum need to change out the DC cabling as the larger inverter draws more current so larger cable is required. To answer the ac side would need a bit more information about how it’s all currently installed.

Thanks @cathbp4089 . Yes, we can do.

Fortunately nobody was hurt and the issue has now been rectified.

Thanks for the comment. That’s actually not correct. The charger will think the battery is full before the battery is actually full and go to float sooner than it should. Leaving the battery less full than it should be. Having a charger many meters away from the battery is a poor design and all charger equipment manufacturers advise against long lengths of cable. Cheers.

Yeah wasn’t great.

Hi and thanks for the comment. As the second battery was fitted by the owner prior to the 18/11/2023 we didn’t need to modify the battery area to have the battery enclosed. However, all of the modifications conducted by us which included additional solar panels etc did need to comply. If you are looking to upgrade your existing installation of you battery by adding another battery you will need to bring the installation up to the standard by enclosing and venting the batteries in accordance with the battery manufacturers recommendations.

@@outechoffgrid Thank you for the clarification cheers :)

Hi and thanks for the comments. Yes I agree further information around specific items such as chassis mounted batteries would have been good to cover however, they aren’t specifically relating to the standard so we felt it was important to ‘stick to topic’ on that. We do cover reasons why it isn’t ideal to mount batteries outside on the chassis in other videos and we could in future do a tech talk on that topic also. Thanks for following along.

Looks like I need to go back over some earlier videos.

Hi Peter and thanks for commenting. To be honest, the best fuses are the ones that are designed for the job they are being installed into. We use Mega fuses on inverter installs up to 3000w. If it’s a transformer based inverter charger we go with T Class due to the extra duty cycle of the charging function and the larger peak capacity of the inverter

In our opinion, any all in one system that is limited to a maximum charge output of approx 30a is fine for simple and basic 12v loads such as lights, pumps usb etc. if you want to run a large inverter based offgrid system you are definitely better suited to larger output systems that have larger outputs in all in one systems or simply replace with individualised components to do the job. That was it’s a flexible system and can be designed to suit the users requirements.

We've seen some doozies....but hopefully this one is a once off!

That’s ok. It may be fine for your needs. Otherwise as you can see from a number of our videos, it’s easy enough to upgrade.

@@outechoffgridit’s now on the list! Now to find a qualified installer as per your recommendations. We are in Wodonga, otherwise I would be giving you a call!

Hi and thanks for watching and commenting. Solar setups have a few factors and space and shading are the 2 main areas we look at. Maximising the array while reducing the impact of external factors such as shading is the most important. Cheers.

It's a matter of personal preference. 🤙

Hi @robynrighton1255 Thanks for watching and taking time to leave a comment. We'll consider your feedback in future vids. 😊

Hi thanks for watching and commenting. In general, these systems add between 50-80kg in weight. As we take out the heavier agms and remove existing solar panels, they are offset by the new system.

$20k plus

Hi Paul, Thank you for your interest in a similar caravan system. The cost of a system can vary depending on several factors, including the specific components, features, and customisation options you choose. To provide you with an accurate ballpark figure, we would need more information about your caravan and your specific power requirements. This will help us determine the appropriate components and design for your system. We recommend scheduling a consultation with us, which can be booked via our website. During this consultation, we can discuss your needs in detail and provide you with a personalised quote based on your requirements.

@@outechoffgrid why don’t you give a price for this exact install then? Not some hypothetical install where you can give excuses not to expose how ridiculous the price is?

Sitting in 'draft'.🤔.. I'll process it in the next few days and will include a link here for you.

Sounds good mate

Hey mate just a question how did run all that solar though the pm335?

We didn’t. We have 2 separate 40a mPPTs plus a dcdc charger in this build.

Thanks for the video mate can you share some information on the solar panel thanks

Hi and thanks for commenting. Quality LiFePO4 batteries don’t get hot. If the battery is getting hot enough to be a concern then either there is an issue with the battery or the installation needs attending to. Enclosing the battery is a safety measure that should the cells inside the battery vent, the gas doesn’t enter the habitable space. Cheers.

Hi and thanks for watching and commenting. No if your system was installed before the recession came out then you don’t need to do anything as the standard is not retrospective. Thanks.

When I say power board, it's a properly wired in gpo.

Hi Brad. Thanks for watching and commenting and thanks for the feedback 👌

You're welcome @Ridds1-us1ee

Hi and thanks for watching and commenting. If you flick through some of our previous videos you will see lots of examples of large systems running aircons as well as videos specifically around some of the new aircons that are super efficient. This build was a great example of a nice small system specifically designed around this clients needs. Cheers.

@@outechoffgridFair enough. I’ll have a look back in your videos for a large system.

Hi Jason. Thanks for watching and commenting. Yes we removed the antenna. There are 2 x 100w panels on the front slope and 4 x 200w on the flat section of the roof.

@@outechoffgrid thanks for that I have a GatorX with 3 200amp panels and 400 amps batts but the solar is not enough. So great to know there’s a solution I’m about to change the tv antenna so it sounds like I have good options now?

@JasonRiddell-us1ee no problems. Solar on vans is like a big game of Tetris. Getting it right can be tricky and we have our methods on ensuring the efficiencies are there. The revision of the standard also dictates how they need to be connected so make sure you understand that. As it isn’t just connecting them all in parallel anymore and hoping for the best. Cheers.
