After a trip to Scotland in the spring the weather was very bad and the solar panel was not working very well at all.
We decided it was maybe a good idea to get a suitcase generator. 2000W and quiet at £400. It works very well and can run the heating at 1Kw and the fridge and charger.
It has an inverter output pure sine.
I have fitted an hours meter so i can service at the correct intervals. I am going to carry in the box and in a large bag with a vent to the outside to stop the smell. Link to manual
