Curious as to status of the recent GS6K's.

Sorry for the lack of communication.

There was an unexpected manufacturing change in the last batch of inverters...considerably increasing the size of the transformer hold-down bracket.  That by itself wasn't a bad idea EXCEPT that it considerably reduces the airflow across the transformer.  Which...reduces the maximum continuous load--to less than 6kw.  (Sean ran load tests several days ago.)

The manufacturer will be express shipping us a full set of replacement transformer brackets as per the original specification.  I'd expect a video about this sometime soon.

Split-phase is standard; Rev. C boards I alas have still not ordered.  Found that my preferred PCB company has serious problems with maintaining SMT assembly item stocks...so I will have to find a different company.

Been busy working on a big project for a friend, so unfortunately the GS stuff has been slipping a bit on my plate...

I'm sorry but now I'm really confused. Sid-you said for me to go split sync sense the test showed a problem with serge at Sean's the slave errored out.so I messaged him for that.havent heard from him so I just messaged him on the forum.so he may have just waisted his time rewiring?I got them a couple days ago.

I think there was a bit of miscommunication...am afraid the inverters didn't get wired for split-sync (i.e. 120v single-phase output).  Will have to figure out what went on, and work out a solution.

Hi Sid so they probably didn't get wired for 48v input either like he and I agreed on not to long ago.i don't have a large 4 ton ac unit to start but I do have a reg submersabl pump and a med ac/heat window unit and a small window ac  &of course washer dryer water heater fridge freezer 5ft.&sometimes 2 little portable 1500w heaters.do you think the inverters would parallel for this or will I have to rewire them for split sync.kinda getting off the wall now.their wasn't a note or anything they are probably 24v dc in.just let me know bud thanks for the response.

Input voltage is easy to check...if you apply battery voltage and turn 'em on, they'll either run happily...or complain about the battery voltage.  All internal electronics can handle 75vDC regardless of the battery voltage specification.

If you need/expect 12kw for loads, they'd kinda have to be internally rewired for split-sync.  Parallel mode is extremely difficult at best, and I can't guarantee reliable operation with it on the Rev. B boards (due to not enough sensors).  FYI reliability is not "inverter failure", but rather just one or both inverters shutting down with an error.

Sean didn't answer back a few texts back about having balancers either I need at least 16 of them.maybe you can find out.would it be possible to send me kind of detailed schematics on rewiring the inverters or how to and not loose warranty?.more work for Sid.thanks

I can work this via PM / video call with you when you're ready (and I'm available, haha!)

Hi Sid if these G6s are wired for 24v would you change them or leave them 24v?If it was yours.im trying to finish a car to sell but should start on them soon.thanks Tim

Well, depends what batteries/solar system I had already purchased / could easily find.

Personally, I'm partial to 48v.  Started my very first solar system @ 48v.  Why, you might ask?  You can literally get twice as many watts out of each MPPT charger...not to mention smaller/thinner cabling due to reduced amps, etc.  Only downside is the need for specially-rated DC breakers; you can usually use just about any AC breaker (with the necessary amperage rating) at up to 32vDC.

Thing about changing a GS inverter from 24 to 48v is that without a variac, verifying transformer wiring becomes difficult.  Oh, and the fans will need replaced with our 48v fans.

That being said, 24v should work fine.  For that matter, it's a lot easier to find DC appliances that run on 12 or 24vDC.  A lot harder to find stuff that runs on 48vDC.

Yes that's fine but I have a regular a/c house.would have been nice if he had just changed these like we talked about and I don't have a veriac?can you find out how it's wired (input output fans)to be sure I don't know if he even tried it out on a bench test or inspected it surely he did.is it terribly hard to ?when we talked about it naturally he said it's easier for them to run on 48v.i will be pulling a good bit of amps a pretty good bit and don't want to work them harder than I have to it's easier to go from 48 to whatever than it is from 24v and on less amps.i think they would last longer on 48 say 4600w than 24v they may even top out acaisionaly.do you think we can do this on a video call?then theirs the fans like you said. I've got charge controllers and a start on 365w panels.may have to rethink it. 😭

About the balancers I don't see any at the store listing?

Yes, we could rewire the transformers / reconfigure the inverters via video call (48v / 120v single-phase output).  But we'd have to get some fans to you for 48v.

Sean most definitely would have tested the inverters before sending them out.  All GS inverters have our very own universal transformer--in other words, out of the box from the manufacturer, they will not function at all.  Sean has to wire them to the desired customer specifications, test them to verify functionality, then ship them.

Umm...they're still on the website just the same?  https://www.genetrysolar.com/gs-balancers
