From genty Mastervolt, give or take a Victron or two. On a serious note a inverter/charger is only one piece in a system, so it would be handy to know what system you already have before any serious recommendations, or if just starting from scratch what are you going to be doing with the boat, power requirements, what other devices you think you need, etc. Edited April 9, 2017 by Robbo Link to comment Share on other sites More sharing options...

If this is the case then a inverter becomes more redundant. So 1 st question, are you on shore power and how often will you be on shore power?

I'll have a 400w wind turbine and 3 100w solar panels I think you need to start at the other end and do a power audit and find out how much power you will be using per day. This will show you how much power you need to generate per day but also what peaks you have (like runing a microwave). Personally I would put money into a built in generator if living aboard in winter and then solar for summer. This PDF is a good read... https://www.victronenergy.com/upload/documents/Book-Energy-Unlimited-EN.pdf note the same technology it goes into is also in MasterVolt stuff as well as others.

As a for instance I live off grid full time and have 440 amp hours of battery capacity and a bit of solar and as a rough idea depending on weather and time of year etc and useage we charge from the engine between 1 and 4 hours per day every day.

Genty Posted April 9, 2017 Author Report Share Posted April 9, 2017 They are only for the odd move. Not going to be cruising or long trips she gonna be more of a movable houseboat but if need I can get more power electric outboards Link to comment Share on other sites More sharing options...

Not going to be cruising or long trips she gonna be more of a movable houseboat but if need I can get more power electric outboards That's 'fine' but from where are you going to get the electricity to power them ? If you currently live in 'bricks & mortar' and intend to life a similar lifestyle (dishwasher, washing machine, hair dryer, electric toaster etc etc) then you will already know your 'usual' electric consumption. Whatever your existing consumption (in KwH) you will now need to generate on board. A 400w wind generator and 300w of solar will just not do the job - you will probably be replacing your battery bank at least once per month as you kill the batteries by taking out more than you are putting in. If you post your monthly electrical usage / bill you will get some suggestions as to what you will need to replicate that with on-board generation.

(ft x lbs) ft/lb is meaningless. (ft divided by lbs). Link to comment Share on other sites More sharing options...

Or do you mean you cruise 1 to 4 hours a day? Link to comment Share on other sites More sharing options...
