Hi Ian I don't think I have ever seen max input current listed as a specification on an Mppt unit. Most are rated for output current which would be the same if wired series or parallel.Out of interest which units are you referring too ? Obviously input voltage does need to be considered.

As others have said the asking price is crazy. It's worth half of that at best. If you do go to view it make sure to make time to walk around the whole site. You will most likely see a few other boats with for sale signs on. Also ring Redhill office and ask if they know of any other boats for sale on site. Boats often change hands there before they have been advertised.

OK thank you very much for that , it makes sense .The only thing I could think of was inrush current.. The inverter in question should never pull more than the output is rated for and and I replaced the 20A fuse suppling the inverter with a 4A one and could not get it to blow. Do you know roughly how much of a higher inrush would it have compared to a fridge or pump ?

And to get back on topic the smaller Victron inverters are also supplied with out the outputs tied to earth.But the manual mentions that you may want to and this is fine.

Hi Nick one of the questions I wanted to know from Renogy was why I should never connect an inverter to the load terminal on one of there Mppt units. I can't think of any reason not to so have done it anyway but you seem to have a great knowledge on this stuff. Obviously the load I have connected is well below the rating of the load output. Sorry Blackrose for the thread high jack.

Renogy's Technical department is most definitely the most useless one I have ever contacted. I have had two fairly simple questions I wanted answers to and they couldn't help with either.

The op stated he was asked to light the cooker, does that mean the oven or the smallest ring on the hob ? Would this matter and if not why would the guidelines say small burner / pilot light ? An oven would use many times more gas than a pilot light. Also what is the problem with metric pipe ? As far as I can see nothing in the BSS says you cant use it or am I wrong ?

The OP has mentioned its a narrow boat.

If the seller of this boat values it as the same same price he values a second hand SR2 I would not waste my money on a survey and walk away now.

How old is the boat and has it been overplated ?

Soar Valley boats are worth a look .They definitely do wide aswell as narrow.

Ask in the office for Rods number.he is based at the marina.

Alan I hope for you and your family to all find happiness one day x

Thanks Mtb that's good to know. Have not used any of their kit yet but I do have one of the mppt controllers and it seems well made for the money. But as they don't cost that much less than victron probably not worth risking.

As others have already said your existing controller is not really the right thing for the new panel. I like the basic Victron 20a mppt as a fit and forget for about £100 or pay about an extra £40 for the smart version if you want to be able to monitor it from your phone. If going cheaper the ep ever or renogy ones might be worth a look.
