We installed a 7225 NG 14kw 200amp switch. It tested fine, sat in standby by auto mode for a week (exterior light green) I woke up this morning and no external lights, control panel blank, control panel LEDs flashing, alternating and being steady. Does not start in manual, executed a hard reset per Generac support and nothing. Dead as a doornail and it didn’t even make it to its first exercise. Battery brand new, and checked 12.3 v I called customer support and they tell me they’ve never heard of this error. It failed while in stasis. It has 0 run hours
