DEYE Inverter UL Listed available in US

Who did you order through

There was a link earlier in the thread to Electriccarparts.com who sells what is apparently the Deye unit. Another person said they had aSunsynk but dont know where they were located. There is also a link on Alibaba that the seller ships to US but doesn't state if its the split phase unit or not. There are also Deye 8k units for sale on eBay from an independent seller in Miami.
I am not sure who you are asking the question to or what particular unit you are referring to. You might want to state that as well as european style vs US split phase style or your location at least the country etc.

Anybody have some results they have documented on the Deye inverters?

A couple of things I saw in the Deye manual concerned me, but I don't know if they are really issues. First, it says that it can be installed outside, but not in the sun, not where rain will fall on it, etc. The SMA SI seems to be the best example of a truly sealed unit (die-cast housing, seal), and the Deye seems to be more fragile with IP65 only. Second, it mentions that you cannot use grounded solar panels. Are newer panels not grounded? Thought that was an NEC requirement (in addition to the racking). There was also an odd statement about turning a connector if near children or something else. Maybe just a bad translation ...

Grounding frames of solar panels shouldn't cause any problems, and should be done for electrical safety. They probably mean not to ground the negative terminal.

The SMA Sunny Island European model is sealed (except for fans). The U.S. model has an SD card and a breaker so it isn't sealed, and is supposed to b used indoors. I found a way to seal mine, and use it outdoors under an awning.

I don't think the Deye can take the heat from direct sunlight.

My neighbor has a Sunnyboy out in the sun and rain.

Found the passage in the manual linked at the beginning of this thread:
"To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. When using PV modules, please be sure NO grounding."

Here's passage on outdoor installation:
"This Hybrid inverter is designed for outdoor use(IP65),Please make sure the installation site meets below conditions: Please AVOID direct sunlight, rain exposure, snow laying up during installation and operation. Before connecting all wires,please take off the metal cover by removing screws as shown below: · Not in direct sunlight · Not in areas where highly flammable materials are stored. · Not in potential explosive areas. · Not in the cool air directly. · Not near the television Antenna or antenna cable. · Not higher than altitude of about 2000 meters above sea level. · Not in environment of precipitation or humidity(>95%)"

This is the odd one:
"In case of children touch or insects go into the inverter,Please make sure the inverter connector is fasten to waterproof position by twist it clockwise."
Maybe that just means to make sure the case is closed and locked?

I don't remember seeing anything like that in the Solark manual but I'll check.

It's like a prescription commercial.
They could just shorten it to "Use this and you will die"

I found this in the Solark manual - "Panel frame grounding can be done to any ground in the home via 12AWG wire. Mounts usually bond frames together, so only 1 ground wire is needed"

But they mention several times that the PV wire shouldn't be grounded.

The Solark wasn't supposed to be mounted outside either at least initially. They apparently have or are in the process of changing that. They have said that they would stand by the warranty even if the unit was mounted outside even without that designation yet.

I don't have my manual in front of me, but I know that the output of PV panels should not be grounded. The DC power leads need to float relative to the AC ground. Your inverter will integrate the ground into the system.

Thanks Haugen. I should have said output isn't grounded but panels frames are grounded.

Yeah, definitely. I think frames get grounded to their own ground, right? (Thought that was for lightning, etc. safety.) Or are you saying that the frame ground should be on the ground conductor and that goes back to the inverter ground in the same cable as the L/N leads?

The language from the manual that I cited, though, seems to say something more. Perhaps that's just in the translation though. A diagram would be helpful.

The way I see it, the frames are grounded to the rod in the dirt that the rest of the house is grounded to.
There is no ground going to the inverter.

Hopefully Haugen or someone else will verify that. I don't have much experience and I don't know if it is the same for Deye.

I'm glad you guys are hacking your way into the Deye with no tech support but I am in over my head even with tech support.

Has anyone paralleled 2 8k DEYE units ? If so did you order the parallel cable separately or did they come with the units?

I am not advocating this but there are people that maintain its better not to ground the pv panels on the basis that it actually attracts the lightning because its a less resistant path to ground that can still cause damage. They basically say it depends on surroundings such as tall trees near to the panels etc that would give a path to ground especially if wet in rain etc. This is kinda like using a lightning rod on top of a building . I am not saying I agree with this or have done this but on some level it makes a little sense but why not do both and be double safe especially with a 'Lightning rod" with as low or lower resistance to ground nearby?

Here is the section of my plans concerning grounding of the panels. This goes through the Jbox to the AC ground in the SolArk.

I just looked at my permit plan and it is the same as yours. The solar panel ground does go to the inverter.
Sorry if I added confusion earlier.
I will stick to the plan unless Solark tech support tells me to do otherwise

Here's an interesting article about lightning: https://en.wikipedia.org/wiki/Lightning_rod

Sorry, didn't see notification on this thread. The link I posted earlier is for the US version. From the seller..

Yes dear,this model is DEYE SUN-8K-SG01LP1-US correct

they also sent a picture, which you can barely see if you zoom in on the model number.
