inverters and the lies

[Bigplumbs]

OK A bit of theory: It takes 1000 calories to raise 1 liter of water one degree C. Assume you need to get i litre from room temperature of 20C to 100C. That needs 80,000 calories. I watt equals 0.24 calories per second, which means that you need to apply 1000 watts of power for about five and a half minutes, plus extra time to actually boil any of the water, which need the application of 212 calories for every gram boiled. Really its not a job for an inverter and mains kettle, and explains why most of us use gas to heat or boil water on board. I would only consider an electric kettle for brewing a hot drink whilst sailing solo when I did not want to go below and light gas. In that case I would consider a 12 volt travel kettle designed to fit into a car cup holder, and therefor capable of fitting into the cockpit table.

Oh god here come the theory mongers. I just bought one tried it out and it worked. Nothing better than real life experience

My Chinese inverter boils a small kettle fine. But it is a smaller wattage kettle on a 110 am battery. Sorry about the wind noise

do you have a clear pic of what you have please

Can anyone recommend me a decent inverter capable of handling around 2500 Watts. I have a Victron 750 Watt inverter and ideally what I'd like is to swap that out and install the higher output unit. I have an existing Victron shore power charger which I've rarely used and hope to never use again after upgrading my solar panels - I've just installed 2 x 400W Maxeon panels. My service batteries total 544Ah with 2 separate cranking batteries.
Among the things I'd like to be able to run from the inverter would be a hair dryer, an air fryer and a George Foreman type grill - not all at once.
Any advice or recommendations appreciated if it's only to tell me my plans are unrealistic.

swap the inverter for a Victron Multiplus II 3000KVA (inverter-charger) wont need anything else but your MPPT inverter

another vote for a Victron Invertor, (or Mastervolt)

Thanks - your advice is always welcome and appreciated. That unit looks to be the dog's jewels but is obviously more than what I need insofar as I already have a good (almost redundant) shore charger. I can't seem to see a stand alone Victron Inverter at the output I require. Space is also limited where the existing Inverter lives and all the cabling is very neatly done so I was really hoping just to swap it over.
I saw this much cheaper unit on Amazon with good reviews - is it too cheap to believe it could be any good?

I'd avoid any 3kW inverter unless it's one of the main 2 brands, but that's me. Also I wouldn't dare buy such kit on the web, I'd want a real shop near where you are that will take it back and replace it or give you your money back when it fails. (note, not if it fails, but when )
I also had a decent Victron Charger, removed it and fitted the Multiplus in its spot and about to sell the charger to reclaim some of the money spent on the multi.
The charging part is rarely used when I run the generator (no shore power where I'm moored)

Thanks. Duly noted and heeded.

Be careful buying inverters that are priced to be reassuringly expensive ? often just the cheap ones at a higher price. I have had good luck with the cheap ones however as in the video previously posted in this thread
