Hello folks - I'm 'noodling out 'what I need for a change from living as a ccer on my own to a ccer with a boat that will have up to 4 people (1 baby) and one 10 year old part time. - I'm getting my 45ft boat extended to 58ft.
My 3 way fridge has come to the end of its life
A washing machine would be good
I'm not familiar with the maths I need to do to work out what my system can cope with and accordingly what else I need
What I have
3 80 watt solar panels
3 105ah leisure batteries
A small alternator (I cant remember its output, its for a 3 pot sole diesel, I just remember someone who saw the boat commenting that it didn't have a great output)
A small inverter (too small)
I have LED lights, a pump for the radiator, gas cooker, obvs water pump for shower, occasionally watch a film on an LED TV, and a laptop.
My MPPT controller can have 1 more solar panel at 80watts
I think I can make room for 1 more leisure battery.
A generator and compressor fridge is too expensive.
So what Id like to be possible - is a conventional in house sized fridge & washing machine, new energy efficient. A new Inverter (2kw big enough?) - If required a 4th leisure battery and solar panel.
Is there an idiots guide to working this stuff out, so I can really sus what I need/what's possible?
Thanks
Martin
