Three Phase Generator.

If there are going to be several people using showers, it makes more sense to use a big water tank with an immersion heater, rather than instant electric showers.

And as it's a camping site, where presumably the bulk of the load will be in the summer - add a few solar thermal panels and heat the water even more cheaply! (just use the immersion for backup on cloudy days)

+1 for having a think about low loads - overnight the load it likely to be a few hundred watts of bollard lighting - I've heard of some off-grid systems that use a battery system and then automatically start the generator to re-change the battery as needed. Generator then only runs part of the time, and when it does run is used at its most efficient full (or whatever) load.

Well here's the thing. The generator has three Ceeform sockets mounted on it. Two blue 16 Amp. types and one red 32 Amp three phase type. A label on the generator says do not allow a load difference of more than ten per cent current imbalance per phase. So is there a problem in running large single phase loads?

generally single phase gensets need a larger flywheel for much the same reason that a single cylinder engine does - the torque on the shaft is proportional to current flow, and that is much bumpier with a single phase load. With 3 phases the torque due to one winding is falling as another is rising, and the mechanical load is more constant. There is also a problem of voltage regulation - which of your 3 phases would you like to be 230V or whatever - the more heavily loaded one will be lower...

That said some designs can be the full KVA single or 3 phase,  but clearly not this one.

White or red?

more of a beer man myself.  If you mean fuel oil it has suddenly got quite messy.

It rather depends if the electricity is for personal use, farming or forestry (Red OK) or for any other business (white) but I expect the rules to be tighted slowly, and red to be phased out in the next few years altogether

No doubt some clever person will get some Redex or get some red  dye into their fuel mix to justify their cheaper prices. Only joking.

Back in the 70s near here, between counties, a road block was set up by Police and Customs to examine the colour of the stuff in folks fuel tanks. A lot of fuel cans were thrown into fields on the approaching road before the road block.
