2000w pure sine wave inverter recommendations

[BOWHOUSE52]

Renoge 2000 pure sine does the job for us the only thing throw away the cables that come with it and put two heavy duty on

Just a quick resurrection of this thread.

I know the op was looking at a 2000w inverter.

Would there be much advantage to getting a 3000w inverter.

It’s mainly for SWMBO to use hair dryer, straightens and I may get a small microwave in the future.

As long as you have enough battery power to run it. I've fitted a 2000w but don't have the battery to run it, I expect to run 500w I went for the larger one for a bit of future proofing and I hope running it at 25% of it's maximum will help it last longer.

Have you got a scale of inverter to battery by any chance.

We’ve got two lead acid 110w batteries at the mo.

Regarding the straighteners. Mrs Sandancers got some small hair straighteners at B&M yesterday, to take on aircraft holidays and in the MH. They are only 25W but she tested them and they do the job ! The cost was only £6-99 !

Renogy have a table showing what battery capacity is required for each of their inverters

I am not an expert so I have no real idea, I ran the milk frother yesterday 480w I checked the input to the inverter and it was 40 amps, I have one 95 A H battery so if I ran that load my battery would be flat (50%) in about 15 minutes. Luckily the machine only takes about a minute to work. If I need more I will have to add more battery power then more solar etc.

Thats a good way of your battery a 95ah battery you should take more than 19 amps out of it.

Thanks for that.

She tried a 12v hair drier and that was a disaster.
She’s got really thick hair, like my head

I looked at gas ones but they are over £100 so thinking inverter is cheaper long run

I did say I'm not an expert, and I do expect to have to upgrade the battery, I'm thinking of a 120AH AGM, would that be OK? Also I know I need to replace the onboard charger but what about the vehicle alternator charge when running?

I should have mentioned that these are 240v straighteners, so you will still need the inverter, but they don't take a lot of power.

You need at least 200ah, AGM would be my last choice not very good as leisure batteries.

2000 watt is fine she who must be obayed is very happy with our set up A lot of people would say 3000 watt give you a better choice But in my opinion it leads to more&more things to put in your van when we all struggle with weight problems

Yes appreciate that, definitely getting an inverter.

I used to view them as (cheating) but not anymore

I definitely wouldn’t be going over the top with “accessories” if I got a bigger inverter.

Looks like a 2000w will be on order soon then

If you want to run it at 2000 watts you need 800 ah of batteries unless they are Lithium.

 

[BOWHOUSE52]

Anything to keep the little lady happy And saved hanging here head out of the window when you are traveling along

If you want to run it at 2000 watts you need 800 ah of batteries unless they arehat I have Lithium.

That's exactly what I have done two 100 renoge batteries 400 watt of solar power and B2B charger Which by the way I have not had to use yet

 

[Silver-Fox]

If you want to run it at 2000 watts you need 800 ah of batteries unless they are Lithium.

Now I’m totally confused.

I’ve got 220ah of lead batteries.

300w of solar.

If I gat a 2000 inverter what can I run on it for how long?

We are talking hair straighteners and hair dryer.

Everything else we use is 12v or gas.

Are these the new fandango type batteries?

No the are not they have been about for awhile But they give you more capacity Lead acid are flat after 50%use Where as Lithium last a lot longer and can run them down to 10%and charge the up more quickly

I did say at 2000 watts with your batteries you don't want to use at much more than 550 Watts.
At 500 watts 2½ hours would take the batteries down to 50%* from fully charged.

With lead batteries if you dra W current at more that the C5 rate you will shorten their life. To get the C5 divide the amp hours by 5.

 

[BOWHOUSE52]

Also they are roughly a third of the weight of Led Acid But they do cost a lot more but are rapidly coming down in price

 

[BOWHOUSE52]

I know this all sounds a bit dawnting but it is the way to go if you can afford to and werth while it took me over two years to get around to it And it depends on the way you motorhome is If you just go out now and again then perhaps not but if you motorhome a great deal that the way to go

 

[Odd-no-more]

It's not just the cost of the battery, they need a different charger and solar charger, also they can be harmed by the alternator voltage being too high

Thanks Lenny HB

This type of thing isn’t my strong point.

Looking at the figures you gave I’m guess 1000w for 15 minutes is ok?
Or maybe not

 

[Billy192]

victron for me it has an eco setting. sits waiting and when you turn on water heating of kettel boom

It will work but you are hammering your batteries you really want to keep to a max of around and 500 watts if you value your batteries.

Ok thanks.

It will be short time of use.

SWMBO will have to make do with a low wattage drier

 

[Odd-no-more]

A big thank you to everyone who has helped me with this project, it's all working well now. One strange thing when I checked the supply voltage with my 16th edition test set it only showed 115 volts when I used a multimeter it showed 238 volts
