If the power in the battery run out, can it seamlessly switch back to using the main power?
More interested to use for powering off solar, rather than as a backup. Maybe when i was in Sabah may have needed many years ago (lots of power cuts). But more interested in directly powering devices direct off solar

If i not wrong,Below is my research,not actual experience
prefer battery 1st will use the battery until the battery limit,and the grid power will take over and continue to provide power.
The app can set the discharge level or full charge level.
And when solar power in,it will use solar 1st to charge battery and dc to ac convert for providing power to device.
For your usage, better just find solar company to install solar panel,high capacity battery and UPS based/grade inverter(for low switching time).
for safety purpose, you may install multiple 200ah deep cycle "lead acid type" battery (got other material this i dont really know the details) for backup power.
If you prefer longer backup time,Lifepo4 battery is also usable and also longlife(1000+ full cycle before reach 80% battery life),but more expensive and abit dangerous than "lead acid type" battery.
The reason why i dont suggest to use Ecoflow product for solar power is because i saw alot of people using solar power to Ecoflow,and either the device auto turn off or something else got different weird issue or breakdown.
And the price like around RM4k for Delta3 and 1.8kw output power. (And it might breakdown randomly or once...)
Just install a fully function solar system will be better for home backup usage. (20k+ if i am not wrong for this kind of usage)
Edited:
Maybe add another PC use grade UPS would be safer with solar system.
