Hello
I just acquired the Bluetti 100V2 for mainly UPS and backup power use to use mechanical devices outdoors.
After 48 hours of testing I find myself with 2 problems.
The first is an erroneous power display.
When my computer equipment is turned off, Bluetti shows me 110W of consumption. my power meter socket shows me 10W with a power factor of 0.1. I guess the display is in VA?
but the screen shows W for Watts. I recently read thread
which seems to confirm this.
It is confusing, always asking me what I left plugged in that consumes so much but I deal with it.
My second problem is a big calculation error of the SoC when I activate the DC output.
it estimates the remaining time taking into account my AC consumption which is in pass-trought.
Let me explain: I connect a ceramic heater that consumes in the 1300-1400W.
with the battery in Custom UPS mode with the SoC High at 80% to prevent it from charging as soon as it loses 1%. I wanted to get an idea of how much % per hour AC consumes in operation to get an idea of how long it would take me to do a full cycle of charging in UPS only.
I lose about 1% per hour which seems to be totally normal.
I plug a device consuming 5W into a 15W USB socket of the Bluetti and I activate the DC.
I notice that I lose 1% per minute, as my AC was consuming the battery instead of mains power. I check my power meter socket and It show ~1500W.
I disable the DC and the problem disappears. I reactivate the DC without plugging in my 5W device and the same problem appears. I turn off the ceramic heater when the battery reach 67% (3% below the SoC low).
I reactivate the standard UPS mode and deactivating the DC input, the battery recharges to about 600W, resumes 2-3% then goes from 70% to 100%, probably noticing that it had not consumed 30% of energy to charge a 5W flashlight for 5 minutes. Does this worry me about a possible battery overload if I do the same scenario at 100% in standard UPS mode? Won’t it try to charge an unconsumed energy? Is this problem known to you? Thank you in advance.

I’m using an EU version of the Bluetti (230V - 50Hz)
Excuse my possibly rough English, I don’t master it yet;)
Best regards.
