I have heard some people got them running. They are selling them as batteryless because they were designed for the original 600 volt Powerwall but when Tesla went with the inverter in Powerwall 2 there was no market for them. Tesla purchased Solar City later and is getting rid of this inventory.
I just commissioned mine. Unbelievably simple compared to the 2012 SMA Sunny Boy SB4000US I just gave up on. The alarm/warning LED is on solid but I think this is because no battery is connected. There has to be some way to set the inverter time/date and change other things via the ZIGBEE interface. Anyone know about that?
Have you set up grid connected or off grid?
Any details about your setup would be great

Search youtube. There is a new guy testing solar with it running Air Conditioner batteryless mode with many panels.
This is a no-battery grid-tie setup. Driven by 8 ea older 245W 60 cell panels on a Sunarx tracker. Collected 17KW yesterday.
I'd say there is very limited support for this unit. I emailed Delta and have heard nothing. Google all you like, you won't find much.
I have some Zigbee stuff from ages ago, time to dig it out and see if I can connect to the unit. Hopefully it spits out XML streams that can be sorted out.

Report on H6 Zigbee stuff: My Sparkfun boards (of which I have many, sigh) are all out of date. Ordered a new one to try out. The Digi application seems pretty nice so looking forward to trying that out.
Under the menus there is one titled "Grid Settings". Didn't really want to change any of that but thought I would navigate through them to see what was there. It requires a password which I thought was 5555 but this didn't seem to work, anyone know what it is?
The Alarm/Warning LED is always on because of battery/Zigbee problems which I'd like to rectify so it turns off but can't figure that one out.
I was amazed that as soon as the sun popped over the Grand Mesa this thing was putting out 500W. Trackers are so nice. At solar noon I was getting about 1,700W.

Heard back from Delta, they have washed their hands of this one:
Hello,
Thank you for contacting Delta Inverter Support.
Unfortunately no, there is no way to turn off this LED light without a SolarCity powerwall battery. This inverter was specifically designed only for SolarCity/Tesla installation and use. Delta no longer provides support nor manufactures this H6 Hybrid model inverter. Tesla has halted all installations of this inverter as well. Any remaining support for these units is strictly provided only to or by SolarCity/Tesla. If you are inquiring about an existing SolarCity/Tesla installation, please contact them for further support and they will gladly assist.
Best regards.

That explains the good price.
I am thinking of getting one h6 myself and use it off grid batteryless mode to power a 9000btu or 12000btu split ac system let's say from 10 am to 4 PM with our Florida sun. It should be between 700w to 1100w load, which is very little compared to 6000w batteryless capability. I have 4.5 kw sunpower 305s panels available. The ac doesn't have inrush current . It has an inverter compressor. This should supplement my main ac. My idea is to use the solar power when is produced, instead of storing it for now. This is the beginning of my project. Most likely i will get some lifepo4 280ah from Xuba,and use a secondary inverter later. Any thoughts either positive or negative are very welcomed and appreciated.
Re: Run minisplit off H6. I don't think an inverter compressor A/C will blow up if you power it up and down in sporadic cycles as clouds pass. It's software will be cussing at you but that's OK ( - : Love to hear how this works.
I picked up a "Solar City Gateway" and the inverter joins it's network. Unfortunately this is a locked system and when you ask to create a new login it just sends you back to the login screen. I'll be playing with it to see if I can hack into it or otherwise open the Zigbee network.

Grid Settings:
High AC Voltage 120%
Low AC Voltage 50%
High Frequency 62 Hz
Low Frequency 57 Hz
Grid Reconnect Time 300 sec
High Voltage Time 0.2 sec
Low Voltage Time 0.2 sec
High Frequency Time 0.2 sec
Low Frequency Time 0.2 sec
Reactive Power 0%
Cos Phi 1.0
As I mentioned I would only change Grid Reconnect time. This wouldn't be a concern if you were islanding the box.
I don't know why designers wait so long to reconnect to the grid. I'll probably set mine to 60 seconds but am REALLY TEMPETED to set it to 10 seconds. Grid around here is a very reliable thing in terms of voltage and frequency, why wait? Remember the 60 Hz frequency still drives most clocks. Maybe things have changed since I looked at this stuff or has regional variation. Maybe just being overly conservative.

I always thought the 300 seconds was part of the original UL 1741 standard and was not a specific inverter setting. I seem to recall in UL 1741SA that one of the reasons for frequency Watt modulation was so that if the grid went skightly off frequency all the rooftop solar would not drop off the grid at the same time. I may be thinking of the CA or HI rules, I don't remember the details.

Could be, I'm not familiar with all the fine print. That does make sense.
That isn't the drop off time, though - it is reconnect wait period. This unit drops out at a few readings below 180 VDC.
You don't want all installations dropping off or reconnecting at the same time though.

I understand, and don't know what the logic was for that long reconnect time. Maybe it was a hardware thing from years ago? I once had an old Xantrex inverter drop off because of high voltage of the grid. When I talked to an Engineer at SCE he told me they regularly adjusted the voltage at substations based on seasonal loads. They had been delayed in adjusting my particular substation back down. That gave me insight into how antquated our grid actually was if that had to be done manually.
I also don't know if the new standard changed the reconnect time or the algorithm. Even if it is still fixed the more random the drop of time is for inverters on the grid then the exact time that individual inverters reconnect will more likely be staggered. All of this is me trying to understand whatever logic went into the stabdards.
