AC200L: power consumption isn't making sense

Unit goes from 100% to 60% in less than two hours.

Competitor unit with the exact same specs doesn't hit 60% for at least 6 hours.

Both had the same items plugged in. The AC Output number is within what's expected (~100W-200W).

The only difference between how they're used, is that the competitor unit doesn't come with a TOU feature - so it's being controlled via smart outlet. The plan is to test that to see if for some reason the UPS/TOU setting is drawing excess power than it should.

Any suggestions are welcome though - to help understand how this is happening and potentially address it.

---------------------------------------------------

EDIT: Confirmed. Apparently, when TOU is active, it's still doing something that draws from the battery as part of whatever it's doing to continually detect the grid status which results in some sort of extra unnecessary drain, like a memory leak (if it's trying to behave like a UPS so it can minimize the ms, there should be an option to disable that, since there are already actual UPS devices connected where they need to be).

Using the smart outlet to cut power to the unit resulted in the expected result - this post was almost 2 hours ago, and since the change over, it's only dropped 5% with an estimated ~10 hours of additional runtime remaining (which is actually superior to the competitor). That we can live with.

So we'll just manage power state with the smart outlet as we did before. But that unfortunately means the one sell point over the competitor (TOU) is no longer a sell point but a negative.

--------------------------------------------------

EDIT 2

Second day of using - fully with the smart outlet.

Noticed that the Bluetti's reaction to SoC may have exacerbated the performance issue.

Expected Behavior

Unit gets to full SoC, it just does passthrough from grid to connected items while trickling out a bit for itself to stay at the top SoC

Actual Behavior

Once it hits the top SoC, the unit will go offgrid and remain that way unless it goes as far down as the low SoC.. The problem with that is, if the charging is done overnight and hits the top at - say - 5a, that's 3 hours of not making use of the off-peak pricing unless we manually intervene. Which isn't ideal.

Next Test

See if setting SoC to 99-100 forces the unit to maintain charge if grid is available. In other words, don't try to be efficient - use what you get, if you don't have grid, go to battery.

Also need to see if Standard UPS behaves any differently; but it didn't from the first quick test done.

------------------------------------------------

EDIT 3

The test was successful. Using Customized UPS with an SoC setting of 99%-100% makes the unit now behave the way the competitor unit does - once grid is back, it juices at the set speed (which we set at 6A for efficiency - any faster is just wasted energy) to get to the top, then trickles to stay there while keeping stuff running. Power goes out, it switches to battery until it comes back. (We're not using solar for multiple reasons, most obvious of which is snow season. We're only using the unit for off-peak pricing enforcement and power disruption mitigation).

Got put into perfect use with an incompetent power company incident this morning and worked a treat - six hours later and it's only down 30%.

This though means that it has no real benefit over the (slightly less expensive) competitor unit whatsoever, because it requires jumping through hoops to get it to behave the "normal" way.

Thanks to all for the suggestions/ideas.
