Quattro unresponsive. No Leds

Good morning…
So the Quattro quit last night. Light loads on it. We are on shore power and its receiving proper AC as well as proper DC from the house Li-ion battery bank. No LED lights. Non responsive to anything. I disconnected and reconnected the link to the VRM at both ends. Have completely disconnect all power, let sit for hour, reconnected. Nothing. Verified battery and shore power to the Quattro.
Any trouble shooting help?

Sounds dead. But also that is weird.

Whats your battery voltage?
