GL trying to get any info or a product delivered! It would seem Hauya and the company that builds them has issues with communication and delivery of this line of products. Looks good on paper, but...

Do they actually? I only know of one person who pulled the trigger on one after being told it was in stock and ready to ship. After waiting months and still nothing being shipped, plus tons of fighting with them for a refund, he finally received a refund (minus fees) after posting publicly about it.

Given their poor communication, not a single unit shipped to the US (that I can find anyway), obviously highly questionable CS and TS (never mind finding parts or warranty coverage), absolutely premium pricing for something with zero track record, etc, I would caution anyone to at least think twice before spending their hard-earned money on this inverter. I will admit the specs look good, but $4k is a big investment on something given the above issues IMO!

The smartest thing they could do is show some CS/TS support and offer some units at a reasonable price to some beta users to build NA market confidence, but that too has fallen on deaf ears!

And then there's the actual inverter manufacturer, Luxpower... never once a single response when I tried to inquire many, many times about purchasing one from them, rather than Huayu given the above.

Would any of this give you warm and fuzzy feelings about paying that much to be the first US user??? That's IF/ASSUMING you actually receive an inverter!

Apparently they have an office in Irvine. That is a start.
At $4,000, is there anything that distinguishes it from other choices in that price range? Is it UL Listed? Does it AC couple with UL1741SA GT inverters?

their 10K split phase inverter surpass every inverter in the price range.

only good for off-grid.

Off grid and out of the jurisdiction of any Authority Having Jurisdiction? That does not work in my County of California, Maybe somewhere? To me that is not a big market when Outback and the other players have UL Listed products that have similar capabilities.

Hence me letting other readers know what the difference is and why it is important for other readers who may be in a jurisdiction that requires UL Listed equipment.

Also for posterity, a product can be listed and labeled but not necessarily “UL Listed”

I’ve been recently reading a lot of code, and technically most jurisdictions don’t actually codify it into their local law that equipment must be UL Listed - that is, equipment certified and tracked (“listed”) to UL standards only by the actual Underwriter Laboratories, although products needing to follow the respective standards set forth by the UL aren’t in question (as that is dictated through the NFPA/NEC that most in the North America use).

So it seems most of the time it is actually left to the discretion of the actual people of the AHJ (the building department) for each permit application and inspection, and most of them find the listing of a product to UL standards (“UL Certified”) by laboratories like TUV and SGS acceptable.

Here are some caps from NEC 2020, also for posterity:

Once you call the Utility company to get Grid Tied that all goes out the Window. Mine actually uses a list of approved Inverters and if it's not on that List it's not going to Pass Inspection. BTW everything on that list is UL Listed.

Same here in California. The CEC website only shows UL Listed inverters.
 
What about your municipality? If you wanted to permit a separate off-grid system, how do they treat those components? What if you wanted to do a zero-export system with no net-metering?

No problem with the utility so long as your just taking power from a plug or something else in the house and feeding it into the Inverter and then it's output is going into a separate loads panel. As to whether your Insurance company will be ok with it is another thing to deal with.

That's a good point. I should find that out. I never really thought about it and figured doing it legally with your municipality was sufficient.

I had been running a zero-export system for years and only recently ran into problems with my city (who is also the electric/gas/sewer/trash company), so now I'm waiting for inspection and being forced into net-metering. I thought I was doing everything legal before, so its been a fun eye-opening experience.

Municipal utilities often have more control over what goes on behind the meter. That is not the case in California with the IOUs who observe a strict line of demarcation.
