Garry that is most helpful. Thank you. As you say phone batteries and a tv is probably all I will use. It is just for evening. Tne generator will run stuff during the day and charge my battery up. Saying that as my tv will work on 12v I assume I could use the caravan 12v oulet plug for it direct and not need an inverter. When it breaks [it is now over 10 years old ] I will get a flat screen so I guess it would be best to go for a 150 minimum inverter
Cheers
