What’s wrong with this?

I have had that effect on at least one campsite, in Spain I think, where neither the 'live' or 'neutral' were tied to earth, but the transformer output was centre-tapped to earth. So (relative to earth) the 'live' was alternating at +/-120V, and the 'neutral' was also alternating at +/-120V. However they were synchronised so that the +120V on one side coincided with a -120V on the other side, so the voltage measured between the wires was alternating at +/-240V.

Was that by any chance a 2 phase supply?
I know you used to get 2 phase supplies in France in remote areas it was an easy way of upgrading from 110v to 220v.

But not on the inverter setting, but Landy Andy thinks it’s good to use regardless

Yes. But as I said. The first pic is just showing reverse polarity which is nothing to worry about unless. You are fiddling with electrical things. So you don’t have any problems.

Thanks Andy, I don’t plan to meddle with things, however I may be having an aircon unit fitting in the near future Would this present any problems?

Funny you should say that……..

Anyone want a tricked up Carthago (with a crappy inverter)

No good for Lenny as he wants a skinny one!

Difficult to say. I’m not an inverter user, but it appears somethings are ok with inverters, and other just don’t work. Text first if available.

With an inverter output live and neutral are identical in that you can only get a shock if you hold both wires. Relative to earth there is no voltage as the

The tester will show same with an inverter generator.
Or it may show no earth.

Also in the US they have 120V circuits, and 240V circuits for high power appliances like ovens. I seem to recall this place was suspiciously near the American base in Rota.

Try the Dolce Gusto Machine. I stupidly tested hers on the lithium battery and it worked a treat . It’s pulling lots of power but for a very limited time so hopefully good for a few coffees . I’ve got a 1200w inverter and the machine is 1500w so inverter seems to be able to cope with the peak power requirements . I say stupidly because now we will be pulling over to make coffee every 10 mins on long journeys. I shouldn’t have said anything

Just revisiting thread as I’m playing around in the van, I’m bored!!
Swifter It will power the machine, then as soon as you want to make a cup it trips off, so I’m guessing a 1500w pure sine wave inverter would do the trick, however would it wreck my carthago 2x85ah gels?

God I need some lithium in my life

Yes, some people get away with it but not really worth the risk.

lol . Then go for it . I’ve been testing mine today with the solar charging ( the Victron MTTP is working well) while using the battery at the same time . I am adding a second Ultramax to the set up soon . We don’t stay off grid much but that’s because of the previously poor battery bank .
