hello, I have a 11kw MAX inverter, which when the AC mains is interrupted, loses most of the saved settings. What could be the reason?

Hello, I need U1:72.03 and U2:12.13 for Axpert 8kw. Can anyone tell me where to download it from? thanks

Please help me. What is the latest firmware for this inverter EASUN IGrid VEII 5.5kw to work in parallel correctly?

I also have another 11 kilowatt inverter which is added successfully but is not visualized in the watchpower app. this is very strange. I am worried that I have not purchased a clone copy that is not an original voltronik and that the data is not visible in the appI have never had such a problem until now

yes but the inverter was bought second hand and I have no idea from which supplier it is so there is no one to turn to. this shouldn't make the monitor unusable. there should be a solution

Does anyone know how to solve this problem

Dude, did you find any software because I am also looking for this inverter

For 11kv (ISOLAR if it matters) can you tell me where to download U1 firmware 67.07 or a newer version. The inverter is from the newer version, which has two outputs (I attach a photo)

Hello, a fairly common problem when buying a used inverter. When trying to add the WIFI module in Watchpower, the program says that it has in another account, and when you have no contact with the previous owner, you cannot delete it and you cannot use the wifi connection. Please does anyone have a working solution to the problem

Hello, I have a Growatt sph 10000tl3 bh-up inverter which has error 418 (software problem). Can someone give me information from where I can download firmware for this model. Thank you in advance

hello, I have an EASUN IGrid VEII 5.5kw upgrade with firmware version 72.40, but the inverter is not working correctly, and that's why I want to update. What is the latest version for this model? Thanks ...

U1 firmware is 72.10 still can't connect. With the ATE1 command, if I have a connection to the inverter, I should see the serial number, then with the next command, I should overwrite the serial number. At the moment, the inverter shows error 90 and a continuous sound without generating voltage at the output.

Hello, I have a PM-5K-48V solar inverter with error 90. (loss of serial number) I try with ATE1 with CommunicationTool-3028 but the inverter does not accept the command. Can anyone help.

Hello, I have a TOMMATECH 11 kw solar inverter. It is currently with U1 57.01 firmware. Is there a newer software and what version is it? Thanks in advance.

it turned out that the problem was in the display. i was able to flash new firmware on the display. now the inverter works normally, but there is no monitoring (not visible in watchpower) what could be the reason.

a question 1: which is the best option for display flash??? I see that at least two types of processors are used embedded in the displays? a question 2: I find 3 variants of flash tool. How do I know which inverter should be flashed DSP with which tool ? 1. King/VM III, 2. MKS III , 3. MAX, 4. MKS IV, 5. VM IV

JTAG or GD32 which would you recommend for display

no success again. and error 32 is still present. Could it be a hardware problem? i know the removable display can be attached to a programmer and the firmware can be read and rewritten without the display being physically attached to the inverter. With the control board, how can this happen? so I can find out if it is damaged or the rest of the inverter.

firmware 41.17 But I can't find firmware with this number. Can anyone help?

Happy New Year Coulomb. I understood the logic you have when choosing a firmware version for updating the inverter. Does this also apply to the display firmware update? and if you can give me direction from which site i can download firmware. Thanks in advance

no they won't be in parallel. they are on separate houses. I just want to update the firmware but I'm afraid that something will go wrong and damage the inverter. I want to know by what criteria to look for an update? if i know for example what u1 is on the inverter how do i know if there is an improved firmware available - update

Coulomb, thank you for your answers so far and since I see you are quite knowledgeable I want to ask you a few things. Yes - the display is on the left side - this is a sign that it is VM 3 and I need firmware for VM 3 - right? I want to know if there was a sticker on the factory DSP chip with the firmware number that was flashed on the particular inverter? And one more important thing - if everything works normally with one inverter, how do I choose the correct firmware for updating??? because I see there are many options and it is easy to make a mistake and the inverter stops working. If I want to update my other inverter how to select the right firmware ???

I disassembled the inverter and found a mini usb on the control board with the processor. does anyone know what it is for and if it is possible to install the firmware directly through it

unfortunately I don't know which version the original firmware was, but I think it should be possible to tell from the serial number which version of the firmware is compatible. can anyone help?

I think the inverter is not working with loads right now. I tried with another straight rg45 cable but again error 32. as far as I understand I need ArenaINVReflashTool and .inv file for 5kv I can't find the same software. Can someone explain what is the difference between AxperKINGReflash and ArenaINVReflashToo and what determines if the inverter is an axpert 2 or 3 if it is a king or ...
