Post Subject: Pure sine wave inverters

Could you please advise of the most relaible & robust pure sine wave inverter, in your opinion, in the range 1200 to 1600 watts and what would you recommend the least acceptable total battery amperage to provide for such an inverter?

Dear Peter, without considerable test lab facilities I am unable to give you a definitive answer your first question, but you should find any of the well known brands satisfactory. The second question is also difficult because you give no idea about the use you intend to put the inverter to. There are two considerations. How much electricity you will use and thus how much you need to store. This is tedious to work out, but you need to do a power audit for the whole boat and work from there. We also need to consider the voltdrop across the battery bank when you are drawing 160 amps from the batteries. On the later point I would install no less than 330 Ah capacity of batteries but you may well have to install far more to cover your load. Tony Brooks
