Suitable Induction Hob?

2800w device + inverter draws about 250 amps from the battery. Make sure the low voltage wiring and the battery are up to the job.

Off the top of my head the Battery BMS is rated at 250A so providing it's not switched to maximum should handle it?
 
Rob, that hob you linked to is 1kw on the right and 1.8kw on the left. Total equals 2.8kw.
You can therefore use EITHER hob on full power or whatever INDIVIDUALY for certain.
Now Colin is correct in saying that some induction hobs give the reduced power by turning the hob on and off rather like a microwave does but at a faster speed. Now I've no idea how yours works but It MAY be that even if you've got both rings set on low there COULD be a point where both rings are modulating ON and still demanding 2.8kw for a short burst? The bursts MAY be limited to half power to make simmering less 'all or nothing' (that's easily done electronically) I've no idea.
Playing safe and going for a lower wattage will guarantee slower boiling times and even 1.8kw isn't massive in hob terms.
I've a gut feeling you'll get away with it but it's Amazon, why don't you just buy it and give it a test drive, if it's no good then send it back?

I suppose what you really need to know is how it actually cuts down the power.
AFAIK many hobs work on maximum power, then cycle the time to give lower power. The manual suggests it might reduce the power, but from experience I'd not always trust a manual to be correct.

Same as most microwaves ....a 1000w (cooking power ) unit
Uses the same overall amount of power to heat the same meal
As a 2000w one ....Just takes around twice the amount of time

I think they are 200A BUT you've got 2 in parallel so in that case 400A max draw.

I was thinking similarly Merl. The fact that the independent hobs actually display the wattage in use (ie. 200, 400, 600 etc) I would think that this would give me good grounds to return the unit if this is not a true representation of the power in use.

From the spec Merl;

  • Inverter Ready: Perfect for use with larger inverters and high-demand setups — handles heavy-duty applications with ease thanks to its robust 250A BMS.
So even more!
 
my induction hob is rated at 2000w but has 10 function settings using the fogstar app i can see exactly how much it’s drawing at 1600 it’s still a lot faster than a gas hob

Sounds like a good way of proving one way or the other Ken.

I have the Fogstar app so will test it when it arrives.
 
Doh!

Just ordered it and something occurred to me - will it fit? - and the answer is NO! so I have just cancelled the order.

Back to the drawing board. :mad:
 
Your like a 15 year old with his first real girl friend Rob :p

Can I do this, will she let me do that.................

Just buy an Induction hob that fits the space you have that's under 2kw. https://www.ikea.com/gb/en/p/tillreda-portable-induction-hob-1-zone-white-70493503/
no she don't come with.

I did a Paella on mine yesterday on my fold out worktop at the back of the van works just fine

Problem is Kev, we need a double one and the only double hob that will fit where we want it to go is the Vango Sizzle (1600W).

I just ain't sure it's going to be up to the job having watched a video review earlier when a bloke ate some raw sausages he had just 'cooked'. 🤮
 
The one thing to be wary of is that most induction hobs reduce power by pulsing on and off from full power. We have the 2000 watt renogy inverter, and it copes easily with the single fitted induction hob from 12volt planet.
We also have a single portable induction hob for when we are on hook up, although, we have never found a need for two hobs.

I read a review earlier where a chap tested the wattage with a meter and like you say they pulse - but only at certain levels (the model he tested anyway). These are the results he got;

"I used a watt meter to see the power supplied by the induction coil at each setting:

10 1890W, 9 1780W, 8 1550W, 7 1460W, 6 1289W, 5 1150W, 4 990W, 3 940W, 2 940W pulsed, 1 940W pulsed"

So that one would suit the Renogy but wouldn't fit the space I've got. I do have to replace the worktop though so it might be doable at a push.

No experience of the vango induction hob Rob, but in general I don't rate vango highly

Having said that, for his test to make any sense the hobs must be 2000w each although it is advertised as a 2000w cooker! :mad:
 
Robmac said:
It's supposed to be adjustable in 200w increments Colin, starting at 200W. The Inverter has a 4000w surge rating so on startup should handle it but I don't know how long it would handle it for.

I could of course play safe and go for the Vango or Outdoor Revolution twin hobs (800w + 800w).

Can't remember what make it was but I was thinking like you Rob with my first induction hob. It gave the 200W increases but in use it didn't work as I thought. It didn't turn down until it had started up and at startup mine pulled full power tripping the inverter.

I ended up getting the single Vango Sizzle same as Marchie and it is fine. I still use gas though and the lekky stuff has been occasional use stuff for me. I really should use it more as I carry a coffee machine, remoska, slow cooker and the induction hob. May be some other bits I don't recall
