Sorry if this is a wrong community to ask these question since my system is only partially DIY, but does anyone have experience with EPS systems like EcoFlow Delta?

I’m trying to figure out exactly how it works when all 3 sources of power are available: battery, AC and solar. Is it able to use them in combination if solar doesn’t provide 100% of demand?

And if anyone is using UPS units, how are you dealing with lack of ground? I’m thinking of daisy chaining UPS to EPS to avoid sensitive equipment from shutting down during failover, but I’m concerned that UPS will not like operating without ground.

    I appreciate the reply. That makes sense and I fully agree with the criticism of my setup.

    I’m in (probably) unusual situation for this community because I live in a city with extremely reliable power. Had maybe one outage longer than a few minutes in the last 5 years.

    I also have whole house solar system without battery backup.

    My idea with a small, of the shelf, system was to create a solar/battery system to use for critical components like my security system, network equipment and optionally garage fridge. Separate system, not hooked up to city grid except to recharge the battery if draw is more than its solar panel can provide.

    That’s why I can live with consumer grade stuff - worst case scenario and I’ll just reconnect everything to city grid.
