I have been using my new AC500 & B300s for the last few weeks without fault.
Yesterday whilst charging from the 230v grid connection the AC500 set of an alarm for code 004 & 098 AND this occurred at the exact moment the Bluetti reached full charge (100%). This has NOT occurred before. At the time I was using the Bluetti in standard UPS form.
Today I again charged the Bluetti from the grid and watched as it completed it charging cycle and again it Triggered its alarm and closed off the inverter ‘AC Off’ and displayed error code 004 & 098.
The Bluetti states Code 004 is Battery Voltage High hardware & Code 098 is BMS Over Voltage.
At the time of this occurring today I was monitoring the voltage when it occurred and it was 232.1volts. As stated earlier, I have been using the system in this configuration without fault for a couple of weeks and don’t understand why this has started.
My Serial Number is:
DSP Version: 4047.03
ARM Version: 4048.02
HMI Version: 6052.04
