Post Subject: Inverters

I am thinking of buying a Sterling Quasi Sinewave inverter 12v..240 1800w. At the moment I have one starter battery and two 110amp/hr leisure batteries. I would be using two laptops, LCD Tv, Caravan kettle, and the occasional vacuum cleaner and toaster. Am I being too ambitious?

I am afraid that only person who can answer that is you. Personally I would be using car power adaptors for the laptops, the gas stove for the kettle and a 12v TV. With brand new batteries you have a bit over 55Ah of usable capacity (if you want long battery life) which would power your inverter when running at maximum capacity for about 15 minutes. You also give me no idea about your use of the boat and charging regime. I have an article about how you do the calculations in the "Articles" section on my website - ( Only you know how you use the boat so only you can do the calculations unless you give me all the information. On the basis of this question I suspect you have unrealistic expectations. Tony Brooks
