I use this device as a UPS. It seems to work stably, there has never been any breakdown or malfunction. Having charged its batteries, it simply passes through itself the voltage from the outlet to the consumers connected to it. The device itself is damn good. It is also worth noting the very durable lithium iron phosphate batteries with a stated huge number of charge-discharge cycles.
The only serious drawback is that when used as a UPS and simply while charging from a socket, it periodically turns on a very noisy cooler to cool down; even turning on quiet mode in the application does not help with this
If the power is off long enough to drain the Bluetti battery, of course the computer would shut off, but when house power is restored, would the AC port on the Bluetti power the load back up automatically? The use case is something like a home router or modem that would automatically boot back up when power is applied. To me, that's a true UPS because the load comes back when utility power is restored, even if you're not home.
the problem with eb3a ups mode is when the device is discharged and then voltage appears, the device will not automatically turn on the 220V output. It was critical for the heater at night.
First of all, I love your channel. Very well done and I wish you much success with it! The problem with the random shutoffs typically occurs when the EB3A is running in UPS mode (i.e. when the Bluetti is in UPS battery bypass mode and powering the load from the grid). While your test was perfect for testing the seamless switching from grid power to battery power and vice versa, to test for the random shutdown issue you'll need to leave the Bluetti connected to grid power so the device is running in UPS battery bypass mode. The Bluetti usually runs perfectly with the load drawing power from the battery, but if you repeat your test and just leave the device plugged into the grid it will likely shut off power to the AC load after 20-30 minutes.
I just bought my new bluetti eb3a. I wonder if I keep using it as ups for my wifi router, how long will it last? I mean, is it healthy if I use it as ups in a daily basis?
it would work fine. These things have a lifespan of full charge discharge cycles so having it act as a UPS means it wouldn't be charging and discharging.
can this be used as a full ups mode? like without plugging out the charger? what happens if its fully charge will the charger automatically cuts the power?
It works quite well as a UPS. The only drawback is the very noisy cooler inside which periodically turns on when the device heats up. The hum is quite loud and being in the same room with this thing is not very comfortable.
Bluetti should keep on testing the EB3A because it has overheating issues.
the forums talk about the EB3A heating up.I had a couple of overheating faults. Also had a weird overload fault when running solar. When the EB3A went full charged 100 % my box freezer when the compressor kicked in set off the overload fault. I wonder if it would be better to use the UPS mode so there is a seamless transition. My other option is dont let the solar fully charge the EB3A to 100%
