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

Does anyone know how to solve this problem

contact the support for your inverter / dongle and get them to release it from the previous plant so that you can add it to yours

What if it wasn't sold but finds a new owner. 

I would think that support might help to locate the previous owner as the previous owner must first delete the dongle or the account to which it is linked. Thus the previous owner will have to log in with the correct credentials before it can be removed. 

This is what I found when a was given a used dongle by the seller of my inverter. He had no further use for the dongle as he upgraded to a different make for his private system. 

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

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

Good luck. Even after my one dongle was properly deleted the manufacturer support battled to get it registered for me as the system kept on seeing the previous registration. It had to be done on the server in China and local staff just passed it on to them.

I swapped my new SS dongle for an old one. The old owner tried t unbind it from their plant but it only worked after contacting customer support in China. 

Hi, I have exactly the same problem. Could you tell me how to do for contacting customer support in China?

thank’s in advance. 

So far I don't have a solution to the problem unfortunately

Hello Vector, thank you for your response. Until now, I was in the same situation! But this morning I tried to unlink my email from my account and I received an email response with a code to do so. In fact, it was not a success but the important thing is that the sender of the email was identified as DESSMONITOR.

On Google, with this name, I found a site where I put the username and password of the WatchPower account and I arrived at a complete complete application where I had all the possibilities to delete the dataloggers inactive and manage those I wanted to keep.
Not only does the WatchPower application with my old account work perfectly again but above all the DESSMONITOR site allows total control of the inverter with graphics, history and everything you could dream of obtaining for monitoring your solar installation.
I'll let you test it and don't hesitate to keep me informed on the forum.
Good day.

I found one website https://www.dessmonitor.com which Ignotus highlighted. As far i understood, DessMonitor manufactures data loggers, and this is the company, who has provided WatchPower app. Their data loggers which are installed in your Solar Inverters, are connected to their server in China. DessMonitor manages all registered accounts, each data logger can be registered with one account only. If your data logger is registered with any one else, either that person removes data logger from his/her account, or may be DessMonitor can remove data logger PN against registered account. Then only you can register data logger with your account.

I found a way if you have forgot your username or you want to know registered username against any data logger PN mentioned on your Solar Inverter. These are the steps you need to take,

1. Go to login area https://www.dessmonitor.com/#/entry
2. Click on Forgot Account?
3. Enter your solar inverter PN in the box
4. It'll show you account username. [Format: us***me]

This is not 100% showed, due to security reasons. but at least you can find out which might be the username can be. The bonus tip is, you can reset your WatchPower password here as well. Then you can login with new credentials on WatchPower app, even you can manage your Solar Inverter from DessMonitor website.

Thank me later

Hi

Do all user names end in 'me' or is it just co-incidental that the prompt for my account also ends in 'me'.

The first 2 letters make sense, but I have tried several options ending in 'me' but none is correct. The most obvious is the user name ends with 'home' so the 'me' could well be correct,

Hi There,

Did you manage to find a solution to your problem, I have the same issue....

I am reaching out regarding an issue with the ViewPower Android application. I previously linked my Voltronic Power device to the app, but the device no longer appears under my account, and I am unable to unbind or delete the account.

I kindly request your assistance with the following:

1. Unbind or reset the account associated with my device.

2. Help resolve the issue of the device not appearing in the app.

Here are the relevant details:

- Account: MTS2025

- Serial Number Device : W0031144953695

- Registered Email: [email protected]

Please let me know if you require any further information to proceed. I appreciate your support and look forward to your response.

Best regards,

Eng. Abdullah
