My installer who has since gone out of business, installed the Cerbo and connected its power cable to the Quattro for power. As such, when/if power fails on the quattros, I lose monitoring. The manual states the Cerbo should connect directly to the battery. I have a bank of BYD LVS Battery Boxes - what is the best method for powering the Cerbo in this config?
If you dont have a bus bar and have connected to the battery terminals of the quattro you will be fine.
It will either power on when AC connects and start charging the DC bus, or from the battery side.
Other programming and instructions are here.
