I am encountering an issue with a "Bus Voltage High" error on the 18k (offgrid) when I attempt to supply electricity to my Sol-Ark 15K (grid-tied) through my small breaker panel. The connection is being made to the Gen port on the 15K. Any assistance would be greatly appreciated, as Signature Solar Tech has informed me that they do not have procedures for AC coupling export. Thank you in advance for any help you can provide.
