Thing is professional installers are reluctant to certify a diy as they didn’t do it and more to the point, didn’t get compensated for it. Why should their warranty cover something that is their core business yet they missed out on bulk margin? I guess there are installers that may but they will check every circuit and cascading fail safes consequently charging heaps to the extent they may as well have done it. I wouldn’t warranty someone else’s work. It’s grief you just don’t need. No reflection on the diyer. Based on that, I am somewhat disingenuous expecting the insurance co t

Me too

The good thing bout installing yourself is when you are 500 miles from shore and it breaks you at least have a fighting chance of fixing it or making a safe work around. DIY is fine as long as its well researched, and as I often do with some professional input and/or oversight. Does the inspector fail it because it was DIY or fail it because it doesn't meet the standard? If I was paying someone to do it - then i would use Matt (but he is so far away!)

Im pumped. First racing in the boat since Northern Triangle. Spent Saturday unloading cruising gear and loading on race sails. Normal co skipper (wife) out for first 2 races, so have a super sub flying up from Nelson. Every night this week is continuing race prep. Last night was spent sewing a stronger lee cloth, now just need to fill diesel, audit safety gear, clean bottom, remove more cruising gear, fit jacklines, remember how to sail, tidy away tools, bail out the rain water, go to briefing, get some food (although not much, looks like a nice reach sail). And beer. Get some

Oi!! Serious lack of excitement this year. Lets get into it. It's not that cold. Very reachy reachy course at this early stage.

Aha, a big silver box.

Here is a pic of how the system works...

Electric.

Nope. There will be a heat exchanger between fridge and freezer. Not yet installed. I'll post a pic when it is, but there are 2 50mm dia tubes between fridge and freezer. There will be a SS plate/cover over them on freezer side, and on fridge side a temp controlled fan takes air from top of fridge, blows it across the plate in freezer, returns it to fridge. There is no air exchanged between fridge and freezer, as that causes frosting. Basically the fridge runs as a parasitical load from freezer. So both cabinets from the one condenser...

I can't see a plate in the fridge? I assume that's the freezer with the plates in it? Do you have fans cooling the fridge from the centre holdover plate?

Is ozefridge electric compressor or boat motor driven?

Its an Ozefridge. Its air cooled until the condenser reaches 38 deg, then it swaps to water (fresh water, borrowed then returned to the tank). Uses eutectic tanks for holdover. Once finished, I hope to be back to one run per day, about 30% of the time in the tropics, less here in NZ... Does not really use the water cooling in NZ, except sometimes in mid summer.

How is your fridge cooled?

For another discussion so we don't get side tracked, I still dont agree that public standards should be behind a paywall. Once upon a time you could go the govt bookshop behind the St James and get or order pretty much whatever publication by any ministry for a nominal fee. Thanks for the library tip CD, you're right we have a pretty good idea of what and how.

Whether you know the rules or not , insurance companies will give you the cold shoulder if you diy without a commercial installer’s certification of proficiency . (Ime, anyway) And they have little comprehension of AYBC E13. Not that there is much to follow. As CD said, he and IT have covered the niceties. Not that it will help the diyers with insurance even if you blind them with contingency electrical engineering. Btw, I used to pay $300 every so often for updates to NZS3604, seems they are mostly free now. Guess there’s not much point in having “industry best practice” behind a pa

Available at public libraries - check out the catalog. There's actually sfa to the Lithium install rules and its content has already been posted in this forum pretty much verbatim.

Plumbing standards, domestic and commercial electrical standards, gas fitting standards, motor vehicle design and construction standards, standards for the construction of houses. None of these are free to access. Again, most people lack the technical knowledge to interpret a technical standard. The ASNZ standard for lithium installations is about $250 in pdf format so it's unlikely that access to the standard is actually holding back people dying to DIY it.

Thanks Matt I'm liking this option I will give yih a call Cheers Howdie

Yes definately need EWOF compliance and risk free installation as far as that is possible. Insurer requires installation or sign off by marine electrician . Burnsco have confirmed none of the lithium battery brands they sell are compliant.

I'll clarify, it's not viable as a standalone business, it would depend on the details of the contract with the council. There are many businesses that are based on non market subsidies and this would be one of them.

Intellectual property? Ok but tightly held by a government organisation that sets standards? Essentially, we're paying for the Information twice. I'm pretty sure the standards related to lithium battery installation are not rocket science, we essentially know what needs to be done but the specifics of it are not publicly available unless you pay. A good an analogy would be an act of parliament, publicly available and with a bit of effort you can understand the gist but to interpret the nuance, you need a specialist

Going south mate!
