Hi there new to the community so I hope it's alright to create a new thread. The narrowboat I'm currently looking to purchase is set up with an alternator, 3 new 12v batteries, no inverter, mains cabling throughout. There is also a generator on board. I'm sorry I can't provide specifics at this point, but even general advice much appreciated. If I continue with the purchase, I'm intending on putting on 4 Renogy 100 Watts 12v Monocrystalline Solar panels and doing my best to use the engine for power as minimally as possible (going into winter I realise that the solar is not going to give much power). The current owner will also be putting on a new 12v Fridge if I go ahead with the purchase. The appliances I intend on running would be a toaster, iron, TV, record player, iMac (I already own this and not looking to replace it), Laptop charger, Mobile charger. I'll be replacing all the current lighting with LED. There is currently a Washing Machine on board but the owner says its best to remove it as its on the mains (makes sense, although I would consider keeping it if anyone could provide a realistic solution). Stove and oven will be gas, have yet to decide on a water heating system. The current gas boiler is defunct. Currently considering a new gas boiler or a back boiler for the burner (no burner currently on board looking to purchase) to fuel hot water (taps, shower) and heating (there are radiators throughout but I'm not sure if they would be necessary once I purchase the burner - she's 63'. To be clear I will not be mooring up and 'plugging in', so everything needs to be off grid power. My knowledge is limited so being completely open, I apologise if my questions appear naive any support appreciated: Is it better to consider investing in a good inverter, or should I look at transformers on an appliance by appliance basis? If primary usage was 12v, would installing an inverter affect functionality or can you run both 230v and 12v with an inverter? I'm not particularly keen to keep the generator but would anyone advise that I do and why? Instead of an inverter or transformers would anyone's opinion be that I simply run the engine (with alternator) when using non-12v appliances, and why? I want to reduce emissions and costs from over using the engine unnecessarily wherever possible. Will the current 'all mains' wiring cause any problems with purchasing 12v appliances e.g. the fridge. If I wanted to consider keeping the washing machine what would you recommend having in place? Thank you for your advice.

Hi there, I am in the process of buying a narrow boat, sail away hull. I have been trying to do many calculations to figure out all of the electrics in the boat. Please tell me if i have got any of the following wrong as im finding that i'm a little stuck. The residential mooring i am planning on using has a 16 amp pylon for a power supply. I have been looking at an Alde 3020 for the heating system attached to a 40l Calorifier for the hot water. The Alde system uses around 1000w which is around 4.3 amps, the Calorifier has a 1kw heating element in it so that's another 4.3 amps. Would you need to use the heating element or would the alde heat provide enough to heat the water on its own. I also have been looking at a standard fridge to cut down on the cost. These at their max they are 750w so that's another 3.3 amps. Then with a microwave oven using 1850w in use max so thats 8 amps. In total that's around 20 amps. That's not including all of the little things in the boat. The main thing i am asking is a) Has anyone got an alde and does it use less current than my calculations. 2) Would i have to use the heating element to heat the hot water up all the time or is the adle enough. 3) are the pylons at the CRT residential moorings defiantly 16amp Thankyou in advance. For extra information. I am getting a 50ft Sail-away to live in the centre of Birmingham

I have been successfully using my Victron 3000 multiplus inverter for nearly a year now, but have a couple of questions. I'm unclear about the earthing arrangement - the manual seems to say that it has a relay that takes care of things (my words) but I notice from the previous owner there is a snipped off earth wire and I'm wondering if I should be attaching it somewhere. I have mains hook up, incoming to the unit (only been used once) then the output 230v goes to a consumer unit and onto the ring. My recent concern comes as as I consider connecting a generator via the ac hook up. (And wondering about its earthing). Also - I can't find it in the manual but is there a special means for connecting an immersion heater in such a way that it is only supplied with ac if the hook up is active (ie so as not to kill the batteries in five minutes flat!). I intend to use the genny to heat water via 230v as well as charge batteries, to further save engine run time - I don't know how effective it will be with a 1kw element in an 85litre cylinder though. thank you
