Hi Schalk Someone has been helping me. I will save the details you have given though. Thanks Gregg

I have a terrible phone but logged in with laptop. Think my firmware version is V 1.1.5_GV1.0.

Hi Fuenkli. I've e-mailed that address and see it's being passed around and me cc'd as they try to find the appropriate person to deal with my problem. Thanks. Thanks Mike except I can't tell you that because I don't know how to check. That's why I want a service provider to sort this for me. I'm investigating a number of avenues and hopefully someone can come and sort.

Hi everyone and thanks for the help. The inverter has wifi and I have connected to it previously although I battle now. The new guy I had looking at my setup said there is a firmware upgrade available but was concerned that if he did it and it didn't work my inverter would become useless. The problem again that he hasn't worked with the blue Goodwe inverters and can't get support from his supplier as they say they didn't import those. Virge when you say contact Goodwe the Goodwe supplier contacted is the same one who said they couldn't support this inverter. Do you mean contacting Goodwe China or another supplier here? Checking Goodwe's website seems there isn't an official importer. Thanks for checking that SilverNodashi. Glad it'll work but still need someone to install and change inverter settings. Mike for sure firmware should be upgraded first. Until then can't really pick any battery but as a matter of interest why do you prefer BYD? Thanks again everyone. Most frustrating having essentially a useless system that for me cost a lot of money.

Grid-tied PV Inverter Type: GW5048D-ES Hope that answers your question.

Thanks Fuenkli Is there no-one here that can help? Surely there must be a number of people with a similar model Goodwe inverter to mine. It certainly wasn't a discount price or under the table purchase so I find it hard to believe my installer is the only one who has used this.

Hi everyone I have a solar backup system with the blue Goodwe inverter at home in Woodmead, Johannesburg. I'm not happy with the service received from the installer. I've had someone else check our system and recommend replacing our old lead batteries with Pylon lithium ion batteries. Apparently inverter settings need to be changed for the new batteries. But they are battling to work with the blue and apparently older Goodwe and say their supplier can't support the blue ones. Could someone please recommend someone who could help. Thanks Gregg
