How to install a 3000 watt inverter in a Caravan part 1

How to Install of a renogy 3000 watt inverter in a caravan for all those off grid adventures, inverters convert 12volt battery supply to 240volt so you can run all those appliances off grid.

You should be using a 400A fuse for a Renogy 3000w inverter...that's whats on mine.....that's what they recommend. The rest of what you have done is perfect.

[@muddyandsandy]

Yeah, pretty sure I only put a 250 because it was only 70mm2....70mm2 rated to 250amps I think, yeah 400 would be good, I don't really use it for big loads....thanks for the comment

[@gavinfisher8049]

Gday muddy. Neat install.❤ Have you adjusted your Inverter setup/RCD since you made the video? Watching vandercampadventures on KZbin a switch contactor is needed for N-E bonding when 240v output supplied from inverter (not on hook up) only then will the RCD function on AC output and protect you. Part of the new regs from Nov 23 apparently. I think the AU regs are similar to the UK with talking to a local sparky. The renogy units already have an automatic change over switch inside the unit..

[@muddyandsandy]

I'll look into it...I have the inverter wired to the change over switch ,which keeps the neturals separated...same earth link though....but ill double check thanks for the info

[@ChappysTravels]

Great video buddy thank you

[@muddyandsandy]

Thanks...really appreciate it...

[@frednurks8528]

Very neat install and for 3000 watt inverter, going to higher amp hour lithium is the way to go. Just a comment on your fuse sizing. 12 volts x 200 amps= 2400 watts . So with your fuse you will limit the load the inverter can supply to roughly 2400 watts. You may have done this on purpose until you get lithium with higher discharge rates. All the best with your electrical upgrade.

[@muddyandsandy]

Thanks for your comment..you are correct with the amperage ,I wasn't sure which one to get,as the cable can handle 250 but the max discharge I can get out of the 300ah lithium battery I'm buying is 200amps... so i just thought of what appliances I will actually use and they are all under 2400watts.

[@itsjustme356]

I just did the same thing on my channel very good install mate sub you brother yeah I went with 200AH Lithium glad I did now

[@muddyandsandy]

Well done....makes things alot easier....i have a ebay 135ah in my ute...been in there for 3 years no worries at all....yeah lithium is the way to go...now I can take my generator out of the tool box...less weight...thanks for the sub..

[@ooshie9293]

A very informative video thank you. When is the next episodes coming please? I am looking to do this over the winter period and interested in the gear you install and how you connect into the existing system. We have a 12 month old van but no wiring diagram. I requested from the dealer but apparently it depends on the electrician/company installing the electrics to your van as they can all be wired differently. I don't believe that. Also sorry my son uses this account for games and hence the name. Cheers Karl

[@muddyandsandy]

Thanks for the comment...I'll be doing install this week....so pretty soon...wasn't that hard to install inverter...

[@StefanBergman]

Is 200A fuse enough for a 3000w inverter? What would you recommend for a 2500w inverter?

[@muddyandsandy]

I wanted the fuse to blow before cable gets hot.....2500w÷13v=192amps.....up to you, as long as fuse size is smaller than cable capacity...

[@joshpettersen5814]

Great video mate! I have the 2000w renogy inverter, not wored to 240v yet, do you have a list of what you bought for your installation

[@muddyandsandy]

Hey mate...these are things I can remember 200/250 resettable fuse from eBay Battery isolator ebay 6m of 70mm2 stranded cable 70mm lugs x8 Inverter 3000watt Heat shrink Liquid nails Spade bits 25mm Screws 16mm 10amp male plug top 2.5mm2 pvc cable 12m 25amp change over switch hager 25mm corrow 10m Zip ties Duct

[@72superlead]

Just installed mine, thanks for your tutorial. I'm getting heat at the fuse and isolator terminals, is that normal?

[@muddyandsandy]

Hey....if you are running high load appliances...there will be some warmth....but shouldn't be a hot..

[@Randwick15]

Like your video. Looking at doing the same Renogy 300W inverter. A couple of questions please; 1 What size cable did you use? 2. is the battery isolator and the circuit breaker needed - could you just manually trip the circuit breaker to isolate 3. You used a 200amp breaker. Renogy suggests 400amp for the 3000W model. Any specific reason. Thank again

[@Randwick15]

70mm cable - sorry I was too quick

[@muddyandsandy]

Hey mate, yeah 70mm2 stranded...you could use just the isolator to manually turn it off...I prefer to use a resettable fuse....not sure why renogy recommends that size..it's way to much...fuse should be just smaller than cable capacity so it can trip before cable melts......3000watt inverter should do ....3000÷13volt=230amp...not sure how it could do 400amps...maybe start up current not sure......I also have installed a rcd straight after inverter..thanks for comment

[@Randwick15]

Thanks. Understand your comment on the 400amp. Strange why Renogy include 100amp cables. Any way I have queried this with them.

[@Randwick15]

Hi Muddy, Do you need to attach an earth wire to the inverter? Trying to work it out and what size wire. Cheers

[@muddyandsandy]

Not to sure about that...the output earth on inverter is connected to earthing system in van....might have to research that one...probably find that frame is connected to internal earth which is connected to my van anyway..

[@Randwick15]

@@muddyandsandy I think is just for static. I got a very non commited answer from Renogy.

[@Aphony66]

Good luck trying to change your batteries out with those brush guards in the way

[@muddyandsandy]

It's pretty easy...it's to the side of the bars

[@vagabondking]

Automatic circuit breaker should be on positive cable and manual breaker allways on negative cable.

[@gandalf2256]

No

[@gandalf2256]

You're wrong AF

[@LEF3133]

@@gandalf2256please explain

[@jerrytalley802]

How did this inverter hold up?

[@muddyandsandy]

It's been good so far....pretty happy with it....might just need a air vent

[@Ian-ev5tg]

Why did you unnecessarily double isolate the positive cable? You could just isolate it with the test switch on the fuse

[@muddyandsandy]

Nothing wrong with adding a isolator...just like your house aircon has a isolator and circuit breaker.....isolator easy to use

[@vicleaguehockeyshow3099]

how does it go with the aircon??

[@muddyandsandy]

Works fine...but always depends on how much amp hours you have in your battery's to run it for awhile.....thanks for the comment

[@extremeacc101]

Your Redarc shunt will monitor your battery usage.

[@muddyandsandy]

That's it...

[@muddyandsandy]

And I have installed a 240v meter aswell..

[@chrisistocool1]

I am planning out my 3k inverter. All the info said I need a 400a breaker and 4/0 awg wire. Am I wrong ?

[@muddyandsandy]

Yeah 4/0 awg would be good...so not much voltage drop....3000 watt inverter can only 230amps roughly...3000w÷13v=230 amp...400amp breaker doesn't sound right....breaker is designed to protect cable before it melts...so the breaker size needs to be similar capacity to cable capacity.......

[@chrisistocool1]

The 4/0 cable has a 440 amp cap. Soni under shot the breaker to 400. My inverter info said it can rock all the way up to 375

[@chrisistocool1]

I am running a 12v system. So I get slapped with high requirements. Pulled this off Google. The current draw will depend on the battery voltage. If the inverter is connected to a 12V battery bank, it can draw up to 350 amps, while if connected to a 24V battery bank, it can draw up to 175 amps

[@ricardovelazquez1650]

I think this needs ventilation

[@muddyandsandy]

I have added this now....thanks for your comment
