Deepinvet:
]1000w/24v = I make that 40-ish amps. BUT, bear in mind that microwave ovens use substantially more power than their advertised cooking power. For example, mine claims 750w output but it’s plated input power is, I believe, about 1200w. Added to that unless you get a (very expensive) true sine-wave inverter, you’ll probably find that the microwave’s cooking power is reduced further, and things take longer to cook.
The wave box are 12v only, would this make a difference? IF A 1000W Inverter worked like that then it would be easier to just buy a cheap £20 microwave and use that, wouldn’t it■■?
Think the wavebox can run on 12 and 24v thewavebox.com/original.htm
