Successfully loaded the MPPT firmware.
However, after loading the Control board firmware the inverter’s display is corrupted. I’ve power cycled the inverter and uploaded the Control board firmware again. Both times the ISP software shows it to be successful yet the display remains unreadable now. No beeps\sounds come when pressing any buttons on it now. Anyway to recover from this?
