Whole Home Backup One Line Diagram
This diagram illustrates the system flow for a whole home backup setup. It shows Solar Panels connecting to 3 Maximum Power Point Trackers (MPPTs), which then feed into the Fortress Power ENVY 12kW inverter. The inverter is also connected to a 48V Battery and an optional Generator. The output from the inverter goes through a Meter, which then connects to the Main Breaker Panel (200A) and the Utility grid. A note indicates this diagram is a guide and for detailed installation information, the manual should be consulted.
