ask first Posted June 3, 2021 Share Posted June 3, 2021 Does the genetry inverters US type works with European voltage? Please explain why? Quote Link to comment Share on other sites More sharing options...
Sid Genetry Solar Posted June 3, 2021 Share Posted June 3, 2021 Yes, you can fully adjust the output voltage from a U.S. 240v to EU 220v, and set the output frequency from 60Hz to 50Hz. Quote Link to comment Share on other sites More sharing options...
ask first Posted June 3, 2021 Author Share Posted June 3, 2021 Thank goodness. I am somewhat confused. Is the US 240v single phase with two 120v each? and the European 220v just one 220v? Also can I use a step up/down transformer if I take my US 240v inverter and use on US and European equipment? Quote Link to comment Share on other sites More sharing options...
Sid Genetry Solar Posted June 3, 2021 Share Posted June 3, 2021 Here's the basic output of a split-phase inverter and it's relation to the transformer design: You can ignore the Neutral line if you just want 240v single-phase. With a GS inverter set up for split-phase output (standard), you shouldn't need a step up/down transformer--you can power 110/120v loads off of one phase (or the other). 220/240v loads can be powered off the total output. And of course, you can adjust the output voltage between 110/120v per half phase (220/240 total output) from the settings. 1 Quote Link to comment Share on other sites More sharing options...
ask first Posted June 3, 2021 Author Share Posted June 3, 2021 So basically the European 220v is base solely of two 110v whereas the US 220/240v is tased of either two 110v or 120v? Quote Link to comment Share on other sites More sharing options...
ask first Posted June 3, 2021 Author Share Posted June 3, 2021 What is the lead time on a 8,000w inverter? Quote Link to comment Share on other sites More sharing options...
Sid Genetry Solar Posted June 3, 2021 Share Posted June 3, 2021 We have stock of 6kw inverters right now, with 12kw inverters planned. It's just Sean in the shop, so it may take a week or 2 to ship out...as he tries to juggle homestead life, personal life, PJ repair work, GS inverters...

Could be, though if the EU doesn't use 110v at all, their transformers will simply omit the center tap ("neutral"). U.S. runs most appliances on 120v, with larger appliances calling for 240v.

ask first Posted June 5, 2021 Author Share Posted June 5, 2021 where can I review the specs for the 6kw and purchase? Quote Link to comment Share on other sites More sharing options...
Ben Posted June 6, 2021 Share Posted June 6, 2021 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 1 Quote Link to comment Share on other sites More sharing options...
ask first Posted June 13, 2021 Author Share Posted June 13, 2021 Thank you there Ben. What is the safest wattage to run the say 6kw inverter? The power jack says 6kw surges at 12kw but continuous at 3kw. What is with these numbers? Quote Link to comment Share on other sites More sharing options...

The power jack says 6kw surges at 12kw but continuous at 3kw. What is with these numbers? Well, first of all...PJ ratings really don't mean anything. GS inverters are tested to the listed ratings, and we know they are capable of handling the advertised load. Quote Link to comment Share on other sites More sharing options...
ask first Posted June 14, 2021 Author Share Posted June 14, 2021 Thanks Sid. I just watched your video from may 30th. I think I'll stick with the 80% rule you mentioned. Where are the specs listed for the genetry inverters? Quote Link to comment Share on other sites More sharing options...

Sean likes to run the 6kw inverter at redline for hours on end--and they handle it with aplomb. 6kw continuous 24/7 shouldn't be a problem. Surge is uncharacterized--actually, we're kinda looking to try to figure out just how much surge his 3 ton A/C unit pulls. We know a single 6kw GS inverter starts it without hesitation, but I don't know what the absolute peak surge there is... Quote Link to comment Share on other sites More sharing options...

I mean to be able to start a AC with 77A start up while running other stuff. thats crazy. I bet his battery screams when it does that though.

I mean to be able to start a AC with 77A start up while running other stuff. that's crazy. I bet his battery screams when it does that though. For the surge load, that is probably mostly down to the capacitors and the inductive properties of the big transformer in the GS inverter for the instantaneous load. That gives the battery enough time to react to the sag in voltage. That being said, if Sean had access to an oscilloscope current clamp probe it would be possible to take single shot tests and display the overall current being drawn in the first fractions of a second and even see how much if any ringing is present when the load starts. That measurement is often not caught by regular clamp meters because they are not fast enough. Some electric motors can surge over 7 times the running current to start but that surge may only be a fraction of a millisecond. It would be interesting to see where the upper limit actually is on an unlocked GS inverter since you could then set a locked GS inverter at 1/4 to 1/3 that limit and know that you have plenty of surge capability without getting anywhere near the danger zone. If I had to guess knowing that I have personally pulled over 4000 watts at 120v through the primary of a MOT with a custom wound secondary with a 1 second impulse. I would guess that the transformer and FETs in a GS inverter could safely handle a 20-25KW surge for a fraction of a second without issue but it is nice to see what it can do in a real world test. Not that anyone should be pushing equipment beyond its rated 100% duty cycle. Some day I need to buy a better bench scope and do some of my own tests on some of the household loads I have around so I can provide some more data to the community.

Very good idea. We can actually "borrow" a standard large-size PJ current transformer, and put it over the battery cable to a GS inverter...it'll give an AC representation of the current (no DC component), but I have calculated/figured out the scale on that, and it might be quite informative.
