Thanks for comments. I must admit there's a whole world of inverters out there. The Chinese cheaper versions, I bought one for our first boat, long since sold on, but it still works fine, but is too small to be useful. Of the the thousands sold how many burst into flames? (Beko fridge syndrome, loads had them but only about 2 caught fire, no big deal unless your one of the two?) . We only use the inverter when away from home mooring as we have a shore supply and again never when we are not about, but it is a worrying factor. I listed Sterling as they are the commonest electrical suppliers on boats, but agree prob not the best. I have no problem saving for a Mastervolt but would be gutted it's the same chinese electricery inside. As a thought. We have a washing machine,tv and a small microwave on board, as well as a genny, so if a bit wash is needed then we would use the genny if away from the moorings. Would a 2kw do us?
