1kw generator, & microwave (1 Viewer)

[lou020]

Hi all you leccy people. I bought a brand new 1kw generator off eBay, says digital invertor generator 1kw but max output 1.2kw. When I tried the 700 w microwave on it,,the genny just overloads and cuts the engine off,also same with the m/h water heater, I'm not using both at the same time! Is 1kw not enough to power the microwave, how do I test the genuine output of the genny.
Thanks for any info

i believe a 700w microwave when switched on will double that to around 1.4kw to much for your genny maybe the heater is the same

it is the start up current of the microwave that can be double 1400W

When I need to select the size of my inverter I asked Technical@baumatic.co.uk for the requirements of the microwave fitted to our MoHo, here's the reply I received.

Microwave oven technical data

Electrical connection rating (W) 1250
Maximum microwave power (W) 800
Power supply voltage (V) 230
Frequency (Hz) 50
Fuse rating (AMPS) 8
Lead-in cable length (mm) 1000
The microwave is designed to operate off a standard 230v,50 hz supply.
The 8amp fuse rating is an internal fuse on the mains filter pcb.
The fuse in the plug should be 13amp. ​

I fitted a 1500W pure sine inverter, it operates the microwave successfully.

The 2kw inverter I have fitted works the microwave ok.
I've read somewhere that the initial start up of the m/wave may be a lot higher. Looks like I'm stuck with the genny which has no use other than charging the batteries... I knew I should've gone for the solars, could've bought two 100w for the price of the genny,,,,,,ah well, you live & learn.

and at least a 1500 watt invertor, mine works the MW a treat
