Is anyone using these inverters in Europe or Asia? I have the cheaper powerjack but I am looking to invest in multiple of these units. I have a 2 and 3 ton AC ONLY unit and don't require heat. how would I go about sizing to get the best gentry inverter. I have asked this question before buy I'm not sure I fully understand the answer I was given.

On this site you can order one I think the specs are on here two

There is lots of videos on YouTube of sean testing and running  the GS 6k inverter

It will do 6k as long as the temp in room is at or below 100 degrees 

Sean runs one that had the safety limit turned of at 8k on a video 

He also started a window ac when already running 4or5k

  I am just a customer i happen to see your question 

You will like the GS inverter

You can set the output frequency to either 50Hz or 60Hz from the LCD screen.  For that matter, you can calibrate the output frequency in ~0.25Hz steps.

Only issue I've been aware of with 50Hz had to do with the output AC filter caps being a tad undersized; that's been resolved on the latest control board.

We are not aware of any overseas customers, partly because we don't currently ship overseas (liability / costs, etc.)

I'm not in the inverter market right now but sooner or later I will be again and would seriously consider a GS if it were available here in Australia.  I fully appreciate that warranty etc would be problematic, but TBH it wouldn't really be any worse than a product supported direct from China and with the better design and engineering that goes into a GS inverter I wouldn't expect a lot of issues requiring parts, in a failure that is warrantable in the first place.

Commissioning would be a stumbling point, ie final connection of the transformer, loading firmware etc.  If the unit was shipped direct from PJ to me I would certainly be capable of wiring up the transformer, visual inspection, loading firmware etc.  That'd require a very high degree of trust in me on behalf of Genetry to rely on me not giving away that all important hex file for the firmware.  Obviously if I was to wire something up incorrectly and bangs / smoke / fire ensues that would be 100% my problem.

So reality is I'd probably end up with a Victron even though the GS would do the job quite nicely.

Sid, I know you are probably just using a serial programmer etc to load the firmware onto the micro, but maybe a solution would be to have a simple cut down software installed on the micro by PJ.  The simple image would essentially be a system that retrieves the proper firmware from GS or pulls it from a usb flash drive etc.  The proper firmware would of course need to be heavily encrypted etc.  Something to consider anyway, if you ever do sell these things outside of the Americas.

Fair assumption 😉.  We have learned from every problem customers have had with the inverters, and take the necessary steps to improve the future designs as necessary.  Rev. C has a number of improvements to further protect the components.

We actually do have several customers in the outlying islands outside of the U.S. (Jamaica / Haiti that I'm aware of), but this was due to their using a forwarding company based in Florida--so we were clueless to the actual destination.  If you can figure a way to handle logistics from Michigan, USA to wherever, that's 90% of the effort.  Obviously, due to logistics costs, any warranty coverage would be rather difficult.  Not that I expect issues with the latest improvements I've made 😉.

Very true...

Sorta...almost 😉.  PJ does not manufacture the WiFi boards; I'm responsible for ordering the PCBs and parts, with final soldering assembly/programming right on my desk...before shipping them back to Sean for installation in the actual inverters.

Look like  Powerjack only do half the work in China .  I  did not know you do the hardest  work of soldering and assembly of the 60  WIFI boards .  That why Sean  do not have time  to repair  Powerjack  returned inverter  or answer  email .

This was posted almost a year ago. Any news? Are your products available in Europe?

So we have sent a few units overseas at this point...but worth noting that shipping costs can definitely add up!  Any overseas customers have to sign a form stating that any Genetry warranty is null and void (for legal purposes), as any sort of round-trip overseas repair shipping for a heavy unit would be absolutely atrocious.  (Otherwise, we might as well just not sell overseas.)

Worth noting that even with the signed form, we will still do our best to take care of any potential issues, with replacement parts, etc. if necessary.  (Dealing with customs can be quite a pain here as well, unfortunately.)

400V European 3 phase?

The manual has a number of 3-phase configurations in it. Page 17 refers to a 415v 3-phase system built with 3 split-phase 6K GS units.

I'm sure there's a reason europe decided to standardize 3-phase in the home... Not sure what it is, but surely a reason...

So feature wise these are Europe ready? So I can buy 3 of them and do a normal 3 phase EU setup like with a Victron for example?

Yes they are.  Configure the output voltage for whatever you want, 220-240v (or even outside that range), 50/60Hz--and if you need 55Hz or something, that is completely feasible.

Depends if you're looking for 208v 3-phase (= 3 inverters at 110v single-phase output), or 380v 3-phase (= 3 inverters at 220v "split phase" output, though you'd simply ignore the center tap on the transformer).  415v 3-phase is the result of 3 inverters at 240v "split phase" output.

 

I so desperately need to update that manual....so much to do!

We have allot of different power systems in the USA as well.  It would be an interesting to see something that shows all the ways to configure them.  Some larger houses in the US have 3 Phase as well mostly used for 3 Phase HVAC systems needed for the bigger houses.  I only have one person that I know that has 3 Phase at home and he is in NC so testing stuff is really hard.
