Hi. I have this GivEnergy inverter (hy 3.6). 
I changed broadband provider recently and went to update the Wi-Fi settings on the inverter. This didn’t go well and, in the course of my failed attempts, a password seems to have been added to the inverter’s Wi-Fi. I now can’t even log into this to try again.
I’ve tried resetting the Wi-Fi by shutting down the inverter and restarting but no joy.
I’ve read that there is also a restart button for the Wi-Fi but that’s on the inside of the system. There’s a demo of this on GivEnergy’s YouTube channel but it’s for a different inverter model where access is via a separate part to the side. I imagine that for me that would be accessible my removing the front panel but just wanted to check if anyone here could confirm / offer any other advice on this?
Thanks in advance.
