Sorry not been on here in a while due to my crazy house renovation, but its time to start trying to work out the electrics aaaarrrrggghhhh. I have 3 interior lights, 3 exterior ones and am thinking about fitting a fridge and small TV. What size inverter would I need? I've seen one in my local garden centre that says 300w on it. Would this be big enough? I'm off to a boat jumble tomorrow so hoping to grab a few bargains! x

Boat sunk with all hands? Not enough fibreglass perhaps or forgot to put the resin in it?
Hope she makes it back - nice lady and got some courage to renovate a boat on her own.
Finally living the dream!

Wonder how Jo is getting on?? Did she use enough fibre glass??
Hasn't visited us since last September. |

I also have 700w and a 2.8kw all still working here in Thailand and all cheapo's.
It is cheap to run and whisper quiet compared to the little 4-stroke. I'm still using it 15 years on.
But technology has moved on a lot, here is a 2-stroke, only 53db, inverter technology, 1500w continuous 2kw intermittant, probably Chinese (although it says Swiss made) but so is my Woolworths one. If you don't overload them they work fine for years.

I used my one on the Ocean 30, sticking it actually on the stern deck (I did have loads of space on that boat of course) and chaining it to the rails. Otherwise I stuck it on the bank on a long chain so no scroat ran off with it. It meant we always had power, for tv, tools, kitchen gadgets, and so on.
do you have one of these cheap honda copies Clive. do they work as they should ? |

Hi I run a fridge off my 100 watt solar panel through a controller,the
Controller is connected to a 110 amp deep cycle battery it will run the fridge all night then it is recharged when cruising during the day
Hope this helps |

Don't get confused with 12 volt fridges.
There are 3 distinct sorts.
1, Old school caravan fridges, often called 3 way or 2 way. These are gas fridges that are able to run on other power sources. When on electricity, either 12 or 240 volts they simply produce heat (like the gas flame) to work. These are not designed to run from 12v batteries but when there is a good power supply like from an alternator on an engine. They can make ice when in good fettle. Great if you have a diesel engine and very versatile. Big NO NO with petrol. BSS forbids new installations, but exist ion OK.
2, Moden compressor fridges. They are designed to run from batteries and a quite low power consumption. They will not run on gas but with an adaptor can run on 240 mains. They are very efficient but make a small amount of noise when running. They will make ice. They are easily identified by the price tag..... usually around £400 - 500.
3, Peltier effect. Usually sold as a 12 volt cool box. Usually cheap to buy but have a high-ish current demand so only much use when the engine is running. More expensive ones have a thermostat and are more energy efficient. Not much good for puling down warm items, but stocked with frozen food and a bit of ice and turned off at night they will suffice for a few days.

Three way fridges eat the electric. 120 watt heater in them which is on most of the time.It will flatten a 110 amp battery in no time at all and damage the battery. If you can run a fridge on gas (depending on safety) they will run all year on a small bottle of gas.Also they run more efficient on gas (colder). Most small TV's will run on 12 volt and there are some excellent led lights to be had. A good quality 300 watt inverter will look after your lap top and charge your mobile phone with power to spare.Just switch it on when you need it.
I had a good deal on ebay with the 4 110 amp leisures I bought. £59 each delivered with 4 years warranty. |

Don't know about the fridge bit, but unless you are going offshore just call a at he nearest supermarket, buy it frozen or chilled add a bag of ice if you want and stick it in the cool bag- box. Move on do the same. As for the tv i have a 14 inch flat screen which goes straight to a leisure battery , ie no inverter so obviously it is built in the tv. It also came with a 240 lead which works off shore to ship mains same as. Iv'e managed full freeview from Ripon to Boston on the river. The tv was £80 ebay, the aerial £20 and the leisure battery was £20 again ebay. WE had a bloke from a £200k dutch barge come aboard at Naburn to watch the tour de france because he could not get a decent picture. lol. INCOMING.

I,m a bit different 2000 watt high quality inverter and 4 110 amp batteries with 120 amp alternator on my engine. |

.... and consideration about the noise.....
Your 30 mins genny run to charge the batteries and watch "Strictly" is someone else's 30 mins watching the sun come down..... quietly!!!

Duff ones! 
Can't remember what make the one I had on Leo was, can't be bothered putting a telly on snowbird as only used it for the weather forecast anyway, I can get that on my phone easily enough now so no point.
Don't even think about running a petrol generator on the boat, there's been a few deaths caused by that trick, unless of course a properly installed 'marine' genset, that will cost a fortune.
Genny's should always be used on the bank with consideration about where the exhaust fumes are likely to end up.

You can get 12v laptop adaptors easily enough, as for voltage stabilisers try good old trusty google (well maybe not trusty) or ebay.

I'm glad this thread has come up. I also don't know if I need an inverter or not. My boat came with two 110ah leisure batteries. They're connected but one was also wired up as the starter battery. Anyway, my 12v usage on the boat is minimal, but I'd like a fridge like fitvit, and I'd like to run my laptop for catch-up TV. I gather that laptops are terrible power eaters, so what would be my best option. As an example, I would like to be able to cruise for a few hours, keep the fridge on all the time, use the laptop, cruise a little again then maybe stay put in one place for a while before moving on. My motor's a 15hp outboard, so how should peeps like me and fitvit proceed?
(By the way, I have found a small inverter on the boat which I think the previous owner used for TV, but I have no idea of what to do with it,and unfortunately, I can't say what it's wattage is since I'm away from the boat while I'm writing.)
Ta ra!

Go on then! Point us towards a "good voltage stabiliser" Dave. |

Or just run from 12V, modern compressor fridges are pretty good on power and smaller flat screen tv's tend to have a power adaptor in the lead which drops to 12v, why step up to step back down again losing power each time, best to use a good voltage stabiliser on the tv though as charging voltage will burn out the lcd backlight and water pumps can cause a drop that will turn the tv off, a stabiliser sorts this.
As said avoid cheap chinese inverters or generators as they will probably kill you or burn your boat, they do lovely test samples then mass produce inferior junk.
