[RE-wrenches] Off-Grid to Grid-Connected -essential loads

[toddcory at finestplanet.com]

i am not sure what the advantage is of running in HBX mode? why not simply grid-tie this where any surplus power (over local use) gets sold to the grid?
 
also the vfx's can be sent into ob for upgrading to gvfxs. no need to buy new inverters.

Wrenches,
I have an off-grid client who is going to be connecting to the grid.  Since the system (~9 kW of PV and ~2400 Ah battery) is already well suited for the loads, I am wondering about the necessity of an essential loads panelboard.  I'm not sure if I see the need since the battery is already sized for all the existing loads.


The intent is to continue running all the loads from the battery and have the (Outback) settings so that the grid is only used when the PV isn't able to maintain a particular battery voltage setting. 


Comments, insights into this type of set-up?
Thanks,
benn
