Try contact sorotec power. I believe they can sell you the display.
Yeah, sure.Hello, please help and advice, I bought an inverter REVO II - igrid ve ii 5.5k, from aliexpress POWLAND Official Store. I installed everything and the inverter works without a problem for 4 months until the touch screen stopped working. The inverter works by restarting the system the display lights up but cannot be controlled after the display goes out it cannot be turned on. I contacted the store where I bought the inverter, writing the case, but so far I have no answer from them. Would you point me to where I can buy a display? I am very disappointed with the maintenance of the store, тhey redirected me to EASUN POWER from where there is no answer to my inquiry for seven days.
Thanks for the reply, I will wait a few more days and if they do not take any action from the store I will contact Sorotec. I am very disappointed with the support of POWLAND Official Store.Yeah, sure.
Sorotec is the company building the units.
They have 2 websites..
(Don't ask me why..)

I receive their sales mailings from:
Email: ella@soroups.com
Last one will probably reply, but never hurts to make your first email to all 3
I have the file only as Docx, and that format can't be used...
So it's a zip
I recognize this behaviour, I have had it as well. :-(..
Firmware update did fix it for me.
In between time, playing with the one-off switch often brought it back to life .
Not ideal, but for now doable in-between solution.
I have to say that I also replaced the one-off switch as it stopped working with that trick after a few months..
(Normally you don't need the display, when it's working fine.
As I'm curious what's happening..
I did the trick a lot ..)
That might have been the fix also...
Both not hard to do.
See previous post for needed files.
The J-Link programming unit is about $7.5
From China, probably locally available also (In your country)
Same for the standard DC switch, just soldering 2 wires..
Can't much go wrong there
I am from Bulgaria, thank you very much for your cooperation. I will try to contact Sorotec if there is no result I can take advantage of your offer. Can you indicate on the printed circuit board on the display where exactly which element is the DC switch? I think I will be able to replace it.AliX...
Everyone is "official" and "professional"
I wouldn't wait more days.
Where are you from? (Country)
I do have a display leftover, if you want, we can swap.
(Naturally, you need to pay for postage)
From Thailand to global is about $35 for courier like FedEx, and $20 for normal transport (Takes a few weeks)
As China is "third world" their postage fees are crazy low.
As you need to return your unit, if might be cheaper to buy from Sorotec.
If you are stuck and need help..
I have a spare, but need your old one back
I received an email from the store that an engineer will look into the case, I hope they replace the display under warranty without sending the inverter to China. I will write about the further development of the case. Fhorst, thanks for your cooperation!The display board and the power switch are not directly connected.
Power switch has 2 longer wire coming from the main board to the switch (+/- 40 cm)
Also from the main board, 2 other wires (different location,) provide the power to the display.
Please follow the guidelines as written above, colour the plugs so you are sure each goes back to the original location.
Mixing 2 will result in a new to buy display and MPPT board.
Perhaps more....
Bulgaria will be indeed about $35, via fastahip.co
Return the inverter back to China would cost you several hundred euro's, plus you can pay tax again when it returns.I received an email from the store that an engineer will look into the case, I hope they replace the display under warranty without sending the inverter to China.

The touch screen does not work to see the exact version of the display. :Return the inverter back to China would cost you several hundred euro's, plus you can pay tax again when it returns.
Change the display is really easy.
3 X unscrew 4 screw.
First the 4 hex on the outside.
Then you have the front panel including the display free ( except the cables, I told you about, colour code them!!)
Pull out the cables (wiggle, they have some "glue")
Remove the 4 screws on the inside of the front panel, you have the screen and bracket.
Remove 4 screw from bracket, you'll need the bracket for the new screen
And put humpty Dumpty back together
What is your display version ?
When you start and the display is accessable, on the "about"
Adjust the bulk voltage down from 58.4 to 56V, 54V float should be fine.Question 2: What Bulk and Float voltages do folks recommend? I selected 58.4V for Bulk and left Float at 54V. The 58.4V was based on reading recommended cell cut off voltages of 2.5 to 3.65V. 16cells x 3.65 = 58.4V as max charging voltage. I’m assuming that the 56V and 54V default voltages are ‘safe’ charging level voltages. Thoughts on 58.4V as Bulk and should I increase Float to say 56V??
Then you aren't looking for an hybrid, but a grid tied inverter.Right, that’s what “most do”. For me I’m looking for hybrids that can supply their max power to the main panel and those loads can still take however much extra power (above the inverters max output) that they need.
I would be using renewable charging from DC-solar only
