Seems I am gathering a bunch of dead inverters from various sources.
Several of those blue ones with the dodgy relays and a couple of Msky? and Aroura's.

Are there any parts ( other than the heat sinks worth salvaging or any thing you can do with them for off grid etc?

What are the Big round things that have heat sings and one wire Coming out of them?
Cap's? Can't see any markings on the things but seem to be a very major component.

Got an SMA the other day with panels but it has an internal Error. Thing is only 3 years old so should be under warranty but I'm wondering if they will baulk because it's not installed now or if there is a way around this with what I tell them?

A picture of the "big round things" would help...

Keep the big heat sinks of junked inverters that have no fan inside, these are good for our LF toroid inverters.

I am thinking chokes also, HF GTIs have quite few big ones from what I have seen.

This could get a bit crude!

Not From Memory, more like a Finned can of Coke. The ones in the blue inverters I have seen under various names are in the very top of the caseing.
I'll try to get some pics Monday. Long, painful weekend ahead.

Apart from the thingys, anything else in inverters worth saving and or Useful?

My half Cooked aurora let out the magic smoke today. Only one tracker was working anyway. getting a pile of these things. Have to start stripping them soon as they are piling up.

On this Vid https://www.youtube.com/watch?v=T1t8rWGt_NA
at about 6:40 you can see what I'm talking about on this inverter.

They are the 3 rectangular things, bit different to what's in the inverters I have but clearly the same function, closest to the camera position.
the ones in the inverter I have a re different and only one wire but obviously doing the same thing and in the same position.

After seeing that Vid I'll give the ones I have a go bending the terminals. Might get a good one.

I read the relays have to be the same ones for the inverter to work if they are replaced. Would that be right or should any DPDT relay of the same voltages/ amperage's work? The OEM ones are about $50 ea I read. Not worth repairing the inverter.

For the ones I can't fix, what's worth keeping in them?

Those things are inductors, might be some value for scrap but not something that is readily reusable.

So long as a relay has the same specs should be no problem.

If you have any PCBs for 5KW Arouras I would be interested in them.

Ha, have a look at these robbers here Scroll down half way, you can ORDER (Not installed) a new fan for $260 It's just a 12v pc fan.

I was looking at this as I scored a dead one and wanted to resurrect it.

Must be a thing with electrical.

Went to an electrical Wholesaler last week to pick up some bit and Pieces and when the guy rang them up I thought he was Joking. No, that was the retail price. They wanted to charge about 4x what I could buy a standard power point at bunnings for.

While I'm standing there still trying to figure if the guy is real, mate walks in. He has an account. $93 comes down to $28. Guy hands me invoice, I say I'd like to pay this please and hand over CC. Unreal.

While some people make a fuss about things from Ebay and china, so much of that the storefronts sell is exactly the same stuff repackaged.
I understand places like Jaycar have rent and wages and everything else but there is no way I can in good conscious pay $84 for a multimeter that is the same with the same Number on it even as I can buy from china for $13 as I did last year.
Yeah, usually you pay for it in delivery time but I had the thing in 8 days.
great meter so I bought 2 more for good measure.

Solar Connectors are the same deal. Buy a bag of 20 delivered for the same price as Local sellers want for 2 pair PLUS delivery.

There is in a lot of things NO quality difference now. It'a all made in china.
In my game, the Chinese Co's started making knockoffs of the OEM products. They were 1/4 the price or less. had a job coming up which I was pretty sure would be a suicide mission for the gear so I thought may as well kill something cheap as exy.
Bought the knock offs and not only did they survive when I didn't think anything would, they are still going years later.

Brand centric mate who said he'd never buy knockoffs got in a pickle and had to borrow them. I asked what he thought when he gave them back and his reply was " I'd never buy original again, not for that they do at ( then) 1/5th the price. "

The Chinese have gone a couple of steps further now and past the knockoff stage and are doing their own products which have VERY useful and game changing features the OEM's just don't have. They are leading the way by far and still a heap cheaper and every bit as good and in some ways better ( easily replaceable and cheap available commonly damaged parts) than the OEM's.

There are still the ignorant operators out there that swear they would never buy that Chinese Crap which is fine by me. I can pass on the cost savings to under cut them on quotes, win the business and still make more than I would have at full tilt with the cost of the OEM gear factored in. They are clueless enough to still think Price = quality level. Don't take into account differences in costs of labour, taxes, Gubbermit subsidies and trade benefits that allow products of the same quality to be produced far more cheaper than western made.

Not everything Chinese is crap by a long stretch. Often it's all Chinese so you have no option. So much is Chinese made with a western brand sticker on it.

Some is crap but if you are selective with what you get..... paying for OEM is just stupidity.
