The 2 buttons are language and frequency
The knobs are output voltage charge voltage and battery type
Looks like you're quite the tinkerer. Is that a three phase rectifier? I've been looking into harnessing "wild DC" as a viable alternative to a typical wind turbine controller. I suspect the typical MPPT control loops will be too loose to work well, though.
Those gridtie units should be able to handle several of those panels each
It's unlikely you will see much benefit from them unless you have a net metering agreement
It's likely you could get better results by combining most of the power into the powmr unit
Is the powmr unit a hybrid inverter (built in controller)
Yes, I have my 3000w hybrid Powmr for a year now seems to work well . I did replaced the blew up capacitors but still working, I went for the PJ for a bit more power but disappointed! “ EBay purchase at your own risk “ not like Amazon sure. Because of my disappointment with PJ I ordered an other Powmr from Amazon.
I spent 12 hours fixing restaurants equipments and unwind the rest of the evening in the garage tinkering….
Is there any purpose or benefits (AC DC adj output voltage charge voltage and battery type) no manual instruction, the one arrived with my unit has absolutely no similarity.

Sure. If you want a higher or lower AC output. For example, i like to run closer to my grid voltage of ~248v. (AKA, i set mine to the highest setting...)
The DC adjustment is useful to adjust the high/low battery cut-offs. (I just set mine to the lowest setting)
Amazon has quite a few powerjack clones. Can't recall the "brands" off the top of my head, but they are definitely the same design. Won't be as cheap as ebay, but with the a-z guarantee, it'd be a great way to twist the odds in your favor.

Great observation! I do have a few of those rectifiers , intended for my direct drive washing machine conversion. This unit with high RPM can produce some good electricity but very low amperage about 3 the most.. unfortunately the fundamental thermodynamic works against me .I do not have continuously running water nor wind on my small acre of property .I have had a lots of naughty ideas. I am sure I will come up with something.
my 12000W 12v EBay wind generator a complete waste money but Look very pretty in the air isn’t.?

I honestly have yet to hear of one person who's truly happy with their wind generator.
1 )1200 AMG PJ ( my disappointment) 24v
Powmr 3000w 24v I think it s a better machine than PJ ( PJ feel and looks better)
Your AMG 12000 watts PJ is not the same as the Powmr 3000w . The Powmr 3000w can connect to the grid and run the house load and charge the battery at the same time . ALL PJ will blow up if grid is connected to the inverter output with the inverter turn ON . Grid can power the PJ INPUT but grid power must be OFF when connect to the inverter OUTPUT . That is what the picture look like for the Powmr 3000w .

ALL PJ will blow up if grid is connected to the inverter output with the inverter turn ON .
Any inverter will risk being damaged if grid is connected to the output with it on.
The PowMr is an HF (high frequency) inverter, which are generally not known for surge capability--or reliability, for that matter!
The Powmr 3000w can connect to the grid and run the house load and charge the battery at the same time .
So can a Genetry Solar inverter 😉. (Rev. C control board really helps.)
IIRC, PJ does/did make grid tie inverters. No idea how well they work - probably not any worse than your typical amazon variety.
