What could cause an "Inverter and Generator Control Unit Communication Error"?

This could be caused by a defective generator control unit (GCU), a faulty inverter or an unclean connection to both of these components. First, check the connections between the GCU and the inverter and repair as needed. If the connections check out all good, verify the inverter and replace it, if found bad. Otherwise, replace the GCU. Additionally, clean and check the generator prior to starting it, as a dirty one can cause severe damage to the component itself.

However, if enough knowledge and skill is not available to do on your own, contacting a verified Expert can serve as the best possible alternative. They will not only solve your problem from the comfort of your home but also help to hold off on an expensive repair.
