Status of Bench Testing of GS inverts.

Sounds good, I would be happy with that part and plu, don't the second shippment has the newer main board?  If Sean don't mind doing that.  He can use those two first gen for hishouse, it shouldn't be hard for him to switch it to 48v, just unpair the two pairs of wire and dasy them to make it a 48v 😛

Hmm. I think I'm going to try firefox, seems chrom on Linux sucks, won't even trasfer my passwords and crap.. . .

Yes, the second shipment use the Rev. B control board, though functionally there is very little difference between it and the Rev. A.1 control board.  Most that you would notice is that the gen start relays are rated for 5A instead of 0.5A.

The major fixes will be on the yet-to-be-ordered Rev. C control board, I'm still trying to get the supplier to understand what I need on that 2-pole 70A latching relay...

Well, also the terminal are going to be better then the first gen. yeah, switch me if Sean don't mind.    And Yep Firefox on linux rocks. its a heck of a lot faster and smoother. also my passwords carry from any device, which is nice.

Hmmm, so Sewn is fixing to ship out inverts even if they are not dasy ready?  Is he going to switch mine to the new model or keep mine until he get the code working?  I'm confused. . . .

Linux Rules, Windows Drewls. . .

*cough*  Update?  Are we getting close to pushing up Daisies Yet?

We are very close.  But it seems that a glass of water sitting on the counter doesn't quench my thirst unless I pick it up and drink it.  Might be close, but doesn't do any good unless I actually do it...

Handling bugfixes and feature additions right now...still tryin' to get that commercial project done and out the door by Monday.  So far so good. 

Sean has one of the 2nd shipment inverters up and running right now, and let's see how soon we can get a parallel demo going...after I tweak and test that code.

Come to think of it, it is springtime, so daisies could be up any time 😉

All the generic Chinese inverters quote the same efficiency figures in my experience.  There's no research there, it's all just cut and paste from someone else's manual.  I've tested a few generic Chinese HF inverters, and as limited as my testing capabilities are, I can still throw a resistive load at them across a range of wattages up to full power.  The stated efficiency figure has little to do with real world performance.  It might as well be, and probably is, 100% made up.

sorry for being late to the boat , but then you also have them Chinese saying you need 10x the inverter wattage  of the wattage of the item you are trying to run (WWWAATTTTT !? ), ( I normally half anything Chinese but 10 fold ??) pretty sure I also read in a PJ Manual  somewhere that their 8kw inverter with 16Kw peak was only allowed to run 2kw continuously 

There is a reason for the 10 x thing with the Chinese HF inverters so they do admit to their products limitations in a way, unlike the PJ where they just outright lie.  The cheaper HF inverters usually don't have much headroom so if you throw a heavy inductive load at them they simply can't supply the start up current and shut down / fold back.  Of course, the cheapie HF inverters have impossible ratings and usually go bang, so they are on par with PJ in the truth department.

been with Ubuntu since V 4.1  think win2k was the last M$ OS I used  bailed pretty fast when Vista came-out 

I was going to go with a PJ when I seen the GS load test of them  and was impressed to see it hitting 10kw

glad I looked for newer video's to find GS started making their own inverter 

Whether or not they say it, that's about right.  Then U-Power comes along and rebrands the exact same unit as a 15,000W continuous, 60,000W peak inverter.  Not much truth in advertising there...!

Funny, the Genetry Solar video you linked is the exact same one that convinced me to buy a PJ just a few years back--after some truly lousy 3kw HF SwiPower inverters.  I had read up on PJ and wasn't expecting to get more than 50% of the rating out of it--but Sean's load test got my attention.  Compared to the HF inverters, the "9kw" PJ was excellent...it could start anything, including A/C units.  Ended up overheating at 3kw, but I hacked up some LCD boards, and made some PWM fan controllers.  Then ended up getting in touch with Sean (thanks to another one, "You lucky dogs and your version 9.0s"--which I had a v9.0!), and it's just gone from there.

Not quite. The 6K is the one that runs 2K continuously. The 8K can push 3K.

Varies I suppose.  My "9kw 48v" PJ would overheat and shut down with a 3kw load.  AS-5 tranny core.  ("8kw" uses an AS-3 or AS-4.)

Let's not mention that that was AFTER I'd modded the transformer mounting so it was standing on end, and there were (2) 200CFM fans on the tranny, one blowing directly through the center of the toroid.

Well if we going to brag about our PJ inverters, my 8k 12v I could wash a set of cloths with the washer, run two freezers, a frigrator, and my computer setup and make it beg to be shot. . .  I know I wasn't even pulling 1500watts and maybe for a few seconds 2k when the washer spun up. . .  and the high speed fan would be screaming and you could hear it pulse when the washer was agitating back and forth, I could even hear the poor coil hum. . .

It seems that they may have gotten a little better with the ASL cored units. But still wouldn't pull the rated Watts. Mine ( GS ) has been getting hammered today by the heat. Officially it is 89° out but with a heat index of 93-95. Shed temp nearly matches the heat index and the unit has been running the 8000 btu A/C to help keep the house cooler.
