CHINA kills all non Sol-Ark branded DEYE unit in the USA this morning.

I don’t agree with what Deye did. But why not just ban the fake picture guy? We don’t need to make a public spectacle of him with tar and feathers. Just ban him.

There wouldn’t be a legitimate reason to do what he did. So any answers he gives will just be a defense of the behavior.

I'm sure there are some folks around here that think tarring and feathering is the appropriate response for what he did. Let's see if I can find anybody to approve. Hey @Nobodybusiness , what do you think? Tar and feather, yes/no?

As the installer, where did you source these inverters from?

I see this as an Installer issue as much as anything. I found it in the email to Will that they were sourced through "Alibaba".

So you source inverters from a 3rd party (Alibaba) into a region that you know is unsupported by the manufacturer (Deye) of the inverter and then sell it to unwary customers as a work-around to buying from Sol-Ark who does support the area. Then you go ahead and connect it to the internet... for updates from Deye. Everyone is shocked that this didn't pan out successfully.

Might as well buy a bunch of charge controllers from Fangpusun (also available on Alibaba) and integrate them with Victron and Outback systems, they are/were the OEM right? Then go ahead and try an update. What could go wrong? :rolleyes:

Without doing any real math, let's use the back of this envelope for a second...

The earth spins at roughly 1,000 miles per hour at the equator, which is about 0.25 miles per second. Assuming 14 samples logged at one minute, the best you could reasonably expect is estimating sunrise and sunset to maybe four seconds, which would be about two miles.

Of course, YMMV.
Click to expand...

If your data is 1 minute intervals, doesn't that mean sunrise could be up to 60 seconds in either direction from the first data point showing solar production so you'd be looking at a possible range of 30 miles? Or am I missing something?

Though I guess having multiple days of data would let you refine that by seeing how many days it takes for sunrise to move from one time slot to the next. That would let you get much more precise as you got more sunrises in your data set.

Fun; I'm going to have to tweak my data collector to stuff the timestamps for first and last second of power generation into a database table just out of curiosity.

Thanks for bringing this up.

Exactly. More days of data equals better resolution of time. A user has offered to loan me some data to play with. Maybe we'll continue this discussion after a few days of data mining.

Is there any implied contractual agreement upon purchase/use of their equipment that gives Deye a "unilateral" power to do as they deem fit regarding the system updates and way in which the inverter is used? In other words, does the user actually have rights to complain about what has happened or not?

I think panel voltage and time might be best. That way you aren't looking at what the SCC thought of power available, just what the panels think about the amount of light on them.

It does occur to me, though, that this would only be reliable for an array facing true South with no shadowing?

You could mitigate that by analysing both sunrise and sunset, but someone in a valley would show as further from the equator than they really are by this method and someone with a SW-facing array would show as being further West than they really are.

That is pretty crappy behavior on his part, assuming he didn't tell the customer that the manufacturer might not warranty/support them.

Deye still shouldn't have bricked them. Prior to this thread, I certainly wouldn't have expected something like that. It just lacks all common decency.

Some of us would be willing to pay "exorbitant" prices for quality USA made goods!

To the point not "exorbitant" but definitely I would pay a premium. I go to the dentist in MX because it's literally 1/4th the cost. I can get it done there without insurance for less than here with. When people start blathering about insurance and regulation, and ... my eyes glaze over. You want to sell USA, you need to lower the expectation, and get costs in the neighborhood. I'm not interested in helping someone re-coup their capital costs in a year, nor getting their income into seven figures overnight.


I'd say my tolerance begins to get lower and lower as the premium approaches 30%.

Sounds about right. The company that could clear the whole situation up instantly, Deye, isn't saying squat. Which is of course, suspicious.

Deye wants this to happen. And sol ark has literally zero power over this.

Makes me question how much control they have over other equipment that they distribute.

Not that anybody has shown. There's no EULA type thing upon activation of the product or anything you sign to buy it. Even if there were, EULAs are crap.

I figured we could get more information or clarity but it was useless. Banned him again. Also on blocklist. Agree with everything you said. Waste of time.
 
It's also legitimate to characterize Deyes actions as damaging Deye manufactured inverters so they could sell the same customers again just though a different channel. Wow twice the profit. Who wants to reward Deye?

When I originally made that exorbitant statement, it was meant to be a joke directed at @Nobodybusiness posts about it and how we paid high prices before, and should and will pay high prices again for quality goods made in the USA like in the 1950's.

Yes it would. I have 2 south facing and 1 west facing and the 45 degree west facing power peak is about 2 hours behind the south facing. Throw in an east facing and the peak could easily be +- 2 hours off of solar noon. Now voltage hitting say around 50% peak is only a few minutes different for mine between the 45 west and straight south panels.
