Huayu Microinverters

[fafrd]

The Huayu Microinverters will apparently be offered for sale here in the US: https://www.huayu-energy.com/

The HY-2000-Plus quad-Microinverter has some impressive specs: https://www.huayu-energy.com/cpxq?product_id=7



The 240VAC / 60Hz support makes it sound as though these Microinverters will be well-suited to the US grid, but I’m curious to know whether anyone has successfully connected one to a grid-tied system here yet.

2kW peak power and 4 MPPTs means this quad-inverter will be able to connect to 5 500W panels (or 550-575W with overpanelling).

It’ll be interesting to see how these end up pricing compared to quad inverters from APS…

I have a question about these quad-Huayu Microinverters (and about quad-Microinverters and dual-Microinverters in general):

Can two inputs/MPPTs be connected to a single string? In particular, can a 1P string / panel with higher power like 600-1000W be connected through a Y connector to two quad-Microinverter inputs to successfully capture all of the power from that string/panel?

This shouldn't be an issue but I did go ahead and toss that over to the engineers to get some feedback.

We haven't tested them yet but we should be soon. Regardless, it's their goal to make them fully compatible with the US market. Note the Safety Compliance line. I don't have the certificates yet but I should soon.

Cool. Look forward to the response…

How long do you expect the compliance testing to take?

And please keep me in mind in case you’re looking for beta testers ,

Just saw that Huayu has established a store on Amazon and their 800W Microinverters are now available through Amazon: https://www.amazon.com/HUAYU-Invert...==&sprefix=huayu+microinverter,aps,171&sr=8-2

At $350 with shipping, they are not exactly ‘cheap’ but considering one of these would replace 3 or 4 Enphase inverters costing $500 to $660, a good deal if they deliver equivalent quality.

The AP Systems DS3 looks to be a better offering, however: https://drive.google.com/file/d/1aY1RyvDp9Az-jay6xCTGtmUTaDDJ2IZv/preview

880VA of maximum sustained output for $200 looks better than anything else on the market today.

3.7A of nominal sustained output current translates to 888W @ nominal grid voltage of 240VAC, so this Microinverter should be able to easily handle 2x450W panels without saturating…
