Goodwe South Africa Poor tech support - stay away

Poor technical support and no accountability We contacted Goodwe for firmware updates on an inverter. I sat on site for 6 hours constantly having to request feedback from tech support. Calls and WhatsApp messages. One update kept failing. It was suggested we leave the inverter on line in order to try and update overnight. This morning I requested feedback. I was told that the inverter had disconnected from WiFi during the night. That means update failed. Since this happened, the inverter refuses to connect to the WiFi again. Support now blames the WiFi (even when all other devices are still working on the same WiFi ) The sequence of events points toward an issue caused while trying to force the update. Dealing with this business is truly exhausting. My client now has no access to his plant and no solution offered at all by Goodwe. If you want feedback from support, you will have to message constantly and phone constantly. They do not take the initiative to update you. The attitude stinks…Goodwe South Africa, you are not doing us a favor. We refrained from using your product in 20teens already. Now I’m having to deal with it again, and since then nothing has changed. I’m advising my client to escalate the matter as well.
