1.5 Functional Overview 

 
The Evolve Hub is equipped to support an AC coupled solar plus storage installation with backup power to a dedicated 
backup electrical panel.  The Evolve Hub is a power distribution center for the Evolve ESS, routing all AC power between 
the main and backup electrical panels.  In the event of a grid outage, the Evolve Hub will be energized by the ESS, which 
will island off the main electrical panel.  As shown below, the PV inverter’s AC output is connected to the backup panel to 
support solar charging of the battery during a grid outage.

1.5.1 Grid Connected Solar plus Storage 

 
The Evolve Hub routes power from the main electrical 
panel  to  the  backup  panel  through  the  Evolve  ESS 
Grid/Load transfer circuit when the grid is live and the 
battery  system  is  in  service  (normal  operation).    The 
EMC  commands  the  battery  system  to  charge  or 
discharge  the  battery  as  demanded  by  the  energy 
management  algorithm.      In  a  self-consumption 
algorithm,  for  example,  the  EMC  calculates  the 
difference  in  total  load  vs.  solar  PV,  and  routes  the 
balance  of  power  to/from  the  battery  as  needed.   
When  the  battery  is  full,  PV  power  bypasses  the 
battery  to  grid/loads.    When  the  battery  is  at 
minimum reserve, all home loads are supplied entirely 
by the grid.  The following diagram outlines the power 
flow possibilities while grid connected. 
 
Note:  The Evolve Hub is equipped with an internal automatic bypass switch which provides uninterrupted service to the 
backup electrical panel when the Evolve ESS is either not powered (installed but pending permission to operate) or out of 
service.
