I have a rebranded kstar inverter which has a "backup" output and I had the electrician wire that output to 6 sockets around the house for fridge, well water pump, and internet connectivity. When the grid is on, the backup is fed by the grid. When the grid goes off, the panels deactivate and the backup is instantly (like a UPS) powered from the 5kWh battery. I can then manually switch off the grid connection to the inverter and re-activate the panels. It should be enough for backup loads more-or-less continuously although I should buy a better fridge and a winter storm might need us to reduce water consumption and disconnect internet.
