I have a Growatt spf 3000tl lvm-48p and an Orient Power LiFePO4 Battery 5.12KW 48V100AH Wall-Mounted/Powerwall that I would like to install in an apartment to be use as backup when there is a power outage.
It is my understanding that this all in one inverter/charger has an ATS built in.
No solar inputs will be connected as this will be mounted inside an apartment.
Looking at my breaker panel, all my critical loads are on one leg and my intent is to use only 120V.
I have seen videos and builds for standalone off grid units and split phases with solar.
But as a single phase configuration with electrical grid as the main source and battery as emergency backup, I haven't seen much.
My question is on the ac input and output under UPS feature as the intent is to use the electrical grid and when there is a power outage, critical loads are automatically powered by battery and when the power gets back, all the loads goes back to the electrical grid and charges the battery.
For this configuration, do I need to create a sub-panel and add a 40A breaker for the AC output coming from the inverter on one side and add the critical loads breakers coming from the Main Breaker Panel to this sub-panel on the second leg of the sub-panel? If this is the correct way, would the AC input from the inverter need to go directly to the main panel in a separate breaker for when the power gets back, it can charge the battery?
Or, can the ac output from the inverter be wired directly to one leg of the main breaker panel and add a new breaker for the AC input on the second leg?
Any information or assistance would be greatly appreciated.
