We were required to do a software update by solis, all was going well until the inverter became unresponsive. The display is lit but all the digits are like black squares. No matter what buttons we press there is no change. It has just stopped working. We have been back in contact with solis and have been given various instructions, but they all require us to select menus on the inverter. They aren't grasping that the buttons don't do anything. So I'd thought I'd ask here if anyone has any ideas about how we get the inverter to wake up and start working.
