Powering a garage/shed without connecting to mains power

How about "residential management company"?

I'm sure that I heard recently that a thing called a portable generator had been invented, it was portable and could generate electricity for a small amount of petrol.

A genny is a rubbish idea.

Have you seen the cost of petrol lately (or diesel)? The tax on fuel is something like 500%, so the electricity will end up costing you loads. Using some stats on generator fuel consumption at part load – it works out about £1.60/kWh.

Compare that to mains electric used to charge a battery is £0.16/kWh. If you assume 50% losses whilst in the charge/discharge cycle that 32p/kWh. OR about 15p/kWh if you have E7 and charge at night.

There’s also the high capital cost especially as the genny will be overrated for running a couple of lights for which you need 100W max, and a small genny sticks out 600W –so will be running at an inefficient load if not on full power. Haven’t seen many genny’s under £500 but there’s plenty of battery lighting under £100.

Finally – you get the choice to stick a genny outside and annoy the neighbours and have it nicked or keep it inside and breathe in the petrol fumes whilst doing a workout.

Now if you are running a mobile catering van in a field – it’s a different story.
