The perfect addition to any off-grid system, whether for a van or a cabin, the Renogy 3000W Pure Sine Wave Power Inverter acts as a DC to AC converter that allows you to power your household appliances. Unlike modified sine wave inverters, this 3000W inverter is a pure sine wave, capable of producing cleaner, smoother, and more reliable electricity to operate tools, fans, lights, and other electronics without interference. Many off-grid systems require a 12V solar inverter to power everyday electronics and this one includes multiple protections to help things run smoothly and safely.

The AC priority switch function enables the inverter automatically switch from the battery (DC) to the mains (AC) and vice-vercer whenever the utility company takes/loses power!

Safe
Electronic overload protection with automatic shutdown.
Built-in internal backup DC fuse provides added safety.
Low battery voltage protection with automatic shutdown.
Over temperature protection with automatic shutdown.
Output short circut protection.
UPS (AC priority switch) function: Transfers input power between battery supply & AC main within 50mS

  Is this overkill for my 2.5 person caravan? It is a 1970s York, fairly tiny and currently set up for 240v with a 250v bar fridge, power points in the kitchen and 240v fairy lights. I'm thinking about putting in a dcdc charger, lithium battery, 12v led lights and a 12/240v fridge. So an inverter could be handy.

  For a 3000 watt inverter i gather I'd need at least a 200ah lithium battery.

      It will still work you just won't get great run times if you have larger loads and it won't be very efficient for smaller loads.

    Not overkill - it's better to have more than you need rather then less - you might want to run a coffee machine or a microwave at a later stage.

    Some older fridge compressors have a quite high inrush current when the compressor kicks in.
    Run your fridge at 12v to avoid the loses in the inverter, but make sure that there is a low voltage cut off for it or you may damage your batteries.

    The larger your battery capacity the more run time you will get before the 10v cut off.
    Make sure the inverter to battery cables are rated at high enough current for the max power of the inverter.

      Thanks for your comments. I used 6b&s for the ute, enerdrive dc2dc and a 100ah lithium.

      I have a 12 pin trailer plug, not sure what size cable they used because the dealer wired it up. Not sure whether it is best to use the 12 pin for caravan power or run more cable to an anderson plug. I'll have to do some research.

    3000watts / 12volts = 250amps…. and that's not allowing for any conversion losses.

    It's less about the capacity of the battery, and more about about how much its capable of discharging in one go (and for how long).
    When this inverter is drawing the full 3000 watts for an energy intensive device (or multiple devices), your standard deep cycle isn't going to cut it.

    You'd be hard pressed to find any smaller deep cycle battery that'll happily discharge 250amps continuously. Some might give burst coverage for like 5 seconds, but most will just trip the safety.

      actually its rated at 3000w continuous output (6000w peak), so that's 3000w/230v = ~13Amps + conversion losses/efficiency, say ~70% efficient = ~17 Amps @12V DC, therefore, max current drain @12V should be roughly (6000w/230V x70% efficiency = ~34Amps @12V DC)

      So at max peak, will draw ~34Amps @12V DC.

      So approx. 17Amps/hr running at 3000w continuous.

        UFO on 19/11/2021 - 21:16

        But that's not taking the 12v into consideration?

        Hey mate, you messed your numbers up a little bit :-).

        3000w at 240v is 12.5A draw.
        However to convert to 12v you need to divide 240 by 20, meaning you need to multiply the amps by 20 to compensate. So 12.5A x 20 is 250v at 12v.

        Now add in conversion losses and you’re looking at 300amp give or take.

        Now I can’t really think of too many devices that will need anywhere near that load individually, so my advice would be to buy multiple smaller inverters to power different devices. The efficiency will be better at lower draw, it gives redundancy and makes it easier to pair an inverter with a specific battery.

        To be honest I have a 1000w inverter and it does pretty much everything I need it to do. I have a 1000w kettle which is perfect for camping (it does 600ml which is enough for 2 cups of tea and does it in less than 5 minutes) and is enough to run microwaves, chargers, tvs etc.

        Only area where you need more power is cooking/heating, but it’s much cheaper/easier to run LPG for gas cookers etc. having enough batteries to run 3000w inverter will literally weigh 120kg+, or require lithium ion which will be $2k+.

        Not saying this is a bad deal, just bigger isn’t always better. Work out what the minimum is you actually need, and buy a suitable unit. Overspecing for no reason will just lead to issues.

        Edit - and if you are wiring up an inverter properly, you’ll need to be using a very heavy gauge wire… like welding wire is probably good for around 150amps depending on the size/quality. Put it this way, for really high end 00 gauge copper wire you’re looking at around $20/m and that probably wouldn’t be enough for 3000w depending on its length.

          @MarcusJones: I think the 6b&s I used on the ute was about 105 amps. It won't be a long cable run from the battery to the inverter, so it won't cost too much extra paying for better cable.

        • 

          UFO on 19/11/2021 - 22:06

          @MarcusJones: That's the number I got in my original post above… 250amps. (P/V=A).

          Bunsen is saying the amps at 230v is 12.5A… which is right, but that's not taking into consideration the 12v supply at all, that's just the amps at 230v.

          That's why I divided by 12v not 230v.
          For the inverter to make 3000w from 12v, it'll need to draw 250amps from the battery. Then there's efficiency losses on top of that.
          Can't make power from nothing!

            @UFO: Looks like you guys are correct. That's a hell of a current though, +500 DC Amps at 6000w peak..

            I took into consideration the switch mode side of things, rather than thinking of a transformer type scenario. Under or over-thinking on my part.

    lgacb08 on 19/11/2021 - 21:49

    to pull 3000w you will pull 250amp from the battery, that's a serious amount of current and will cause all sort of trouble so a few battery in series at least, and better not doing it and get a smaller rated inverter, unless you have ample amount of batteries connected together

      Parallel, not series.

      In series the voltage will be added, and you'll end up with a 24v battery.

        You are correct.

        I think Igacb08 is actually recommending a higher voltage inverter, and two or more batteries in series.

        Note that high-voltage DC is quite dangerous, so I suggest a 48V inverter and 48V battery system (4x 12V batteries in series), which will give a much more manageable 62.5A for 3000W draw.

        While higher voltage would give even lower current, inverters rated to higher than 48V input are rare, and more than 48V is also getting into the "dangerous" voltage range.

    I have had this exact model in our caravan since the start of the year, properly wired into the full van via an RVD for correct safety, and via a double pole isolation switch, for when camping off grid. We do have 600Ah of lithiums though (2x300Ah), with 800W of solar. I intended to just do a 2000W mainly for occasional off grid air con, but ended up with a 3000W so that I could run the air con plus other devices at the same time if I ever needed, as rare as that may be. One battery of that size would have sufficed for the 200Ah but we wouldn't get much run time, so I figured if already setting it all up, just go dual batteries and upsize the inverter. Only reason you would really need the 3000W would be if ever running the aircon plus other appliances. If no air con then ddef go a smaller one.

  Judy - can you please advise if this newer model https://www.renogy.com/2000w-12v-pure-sine-wave-inverter-new… is coming to Australia in 240V? I like the smaller form factor.

    Grunef on 20/11/2021 - 07:26

    That does look good.

    Bluetooth would be good for tracking loads too.

    It would also be good to modify the low voltage disconnect settings etc.
