1000w power invertor - enough for a microwave?

[sailorman]

as above really?

assuming a small microwave is 750/800w normally, logic would dictate yes its fine but i know sometimes numbers arent what they seem.

I dont think id be plugging anything else into that system, as everything else im looking at is 12v

some microwaves prefer pure sine wave, mine wouldnt work with a mod sine wave.
I have a Studer 1200
The Kipor 1kwh will run the mw

Our microwave is very picky and takes at least 25% longer to cook things via the generator versus shore power. The generator is an inverter model and is often said to be as close to the correct sine-wave as you are likely to get.

Capacity isn't the problem as the Honda EU20i will output 1600W and we are careful not to exceed this figure (though it will handle 2kW for short periods). No other problem apart from extended cooking times.

I have a 2000W pure sinewave inverter. I hardly use it as I have found out that peak startup loads for sub 1000W devices often excede the capacity of the inverter causing it to trip. This includes the small fridge, the microwave and small power tools like hand drills. In fact I haven't found much use for it at all. It also kills the house batteries. Some have found great success using inverters, but tbh I found that getting appliances that can use an inverter such as TV's and laptops etc successfully are better served by getting 12-14V compatible devices or DC voltage step up (i.e. 18V for laptop) rather than going to 220V AC then transforming down. My inverter also has a constant 2 amp load just to run, it is a battery killer imo. Where that leaves you with the microwave, I dont know. For that I use a genny.

What type and model of inverter do you have?

Worth bearing in mind that 1000 Watts equates to more than 80 Amps of current draw at 12V, so you need ample capacity and very fat wires.

Of course you need enough battery power, but fat wires are only required between the batteries and the inverter.
Which is a given in any half decent inverter installation, and also a reason for placing it as close to the batteries as feasible.
Downstream of the inverter, AC cables are just the usual ones.
