Great! where did you find that? I looked on their website and could find no tech info on it at all. I did find that they 1st came out with a 15 Kw version, which might be better suited for residential use.
The 3-phase system makes sense for a device of that size. It matches what other V2X devices of similar size are using:Pg 41 480v three phase!
I didn't see anything about any way to throttle it back, So no installing in lower configurations.
I did notice when I was looking that a FE15 was produced as well, not sure if this replaced it or is concurrent.
Again, CAN does not equal DOES.No, you need to understand that it can and will bi directionally load/charge at 20 KW, It isn't just an inverter to supply power to what you plug into it. If that is what you are looking for, than look into Seltec's unit.
Because it probably wasn't designed by chimpanzees? Heck, even the barely functional chinese grid-tied inverters are configurable and throttleable. In fact, point me towards ANY grid-tied system that can't throttle. I'll wait.You say "of course it is throttlable" where is your info from?
It will supply/accept exactly what it's TOLD to, up to a 20kw max. There isn't a grid-tied system in the world (or really any inverter at all) that doesn't have the ability to limit. Something not grid-tied is inherently limiting – it simply tries to reach a voltage target. If there's no load, it's easy, if there's too much load, it won't make it and will probably cut out or complain. With grid tied, it's a little more complicated, but they're REQUIRED to follow the incoming AC and derate all the way up to turning off completely based on frequency shifting. There are also building/UL/etc codes requiring devices to be configurable with respect to load/generation. For example, the Tesla Powerwalls and Wall Connectors both have settings, and used to have (maybe still?) a PHYSICAL control for throttling because that was required by silly law.It will supply what ever it "sees" up to its capacity.
When you plug into to a Chademo F/C it can supply 80kw to the battery, This is also a fast charger, and has to have power connections that are up to what it can provide.
No, I'm very much not. You're mistaking me for someone who isn't an engineer who designs electronic systems.You are mistaking this for an inverter that you might connect to the car to run a few items.
Again, 20kw is not that much. Yeah, it'd be on the big side, but anyone with two powerwalls is close (on the generation side) and anyone with electric tankless is likely past it. That said, this unit is obviously gonna be three-phase 480v.20 KW is going to take a lot of power, no indication if it is 3 phase or single, it could be single, but that would be at the high end of what would normally be use on single for a single item. It would require a 120 amp circuit at 240 volt single phase with cabling to match. 3 phase 480 volt is more likely.
^^^ This is awesome, thanks for posting it. Yeah, not too many homes with 3-phase 480v drops. I actually considered trying to get PG&E to upgrade me to that (commercial grid-tie inverters are SOOOOO cheap!!!!) but I knew that'd be an uphill battle.Looks like we need a volunteer to read the operating manual. https://prismic-io.s3.amazonaws.com...4a31c052c2f_FE-20+Technical+Handbook+V2.3.pdf
Edit, see page 41 Rated Power -20 kW / +20kW @ (-35 – 45) °C . From what I can see on line, the grid feed operation is controlled remotely through a 'back office" interface which is designed for rate arbitrage. It does appear to be 20 kw only, on or off.

In collaboration with the pilot program partners, Fermata Energy’s bidirectional charging platform enables the parked electric buses to be utilized as mobile batteries with stored energy discharged to mitigate peak energy demand, send power back to the grid, lower the vehicles’ total cost of ownership and create value for electric fleet operators.
UL 9741 covers bidirectional EVSE and applies to V2G-DC as well as V2G-AC systems. As written, the standard relies on UL 1741 for guidance, evaluation, and testing to meet grid integration requirements. Unlike UL 1741 which only applies to discharging, UL 9741 could be used for charging and discharging. UL 9741 is changing and will likely continue to evolve to align with 1741 revisions. The new version of UL9741 may also include requirements for off-grid power generation (e.g., V2H, V2L).The May 2021 UL 9741 release covers both unidirectional and bidirectional equipment connected to EV. This also includes bidirectional equipment that is configured to operate in unidirectional mode.
Next time I am recovering from surgery, and can't get out of bed for a week, I'll read that through!
Crap. Stupid 480V 3 phase. Why does Canada have to have a different 3 phase voltage?Looks like we need a volunteer to read the operating manual. https://prismic-io.s3.amazonaws.com...4a31c052c2f_FE-20+Technical+Handbook+V2.3.pdf

FE-20 requires 480V, 60Hz, 3-phase serviceWhile interesting, I don't think it will be showing up in consumers houses. 20 KW is more than most houses can handle and still supply the house.
I could find any spec on a cursory look. so don't know what input power it needs.
Yes, we know that now, after MikeinPA found the manual. At the time that was written we didn't have access to the spec's.FE-20 requires 480V, 60Hz, 3-phase service
again, 20kw is just fine, and pretty standard for residential. what’s totally disingenuous is them claiming 480v 3-phase is suitable for anything except commercial.It defiantly wasn't clear in the press release. 20 Kw or even 15KW is right at the cusp of what would be considered "too large" for residential
