Our first install of a Flexboss21 w/ a Gridboss doing whole home backup ( 200A main panel ). After updating the firmware, before connecting the Flexboss and the Gridboss together with the parallel comms cables. I was comissioning the system and found that the ESS switch for the Gridboss doesn't do anything. Anybody run into this one? am I missing a setting?
Thanks for any assistance.
