Hi!
I bought eb3a somewhere at the end of 2024 and used it quite rarely. Russia began to actively shell power generation systems in Ukraine, and now I needed my little charging station.
I use it in combination with a laptop and monitor. The monitor is powered by AC, and the laptop is powered by DC type-C. When only the monitor is running, it consumes 10-20W (sometimes less and therefore does not show).
Everything worked fine for a month, but now the station can randomly turn off the AC output without any warning. DC continues to work, the station does not turn off. The station clicks (as when turning AC on/off), the AC icon flashes, and the monitor goes blank.
This definitely happens in UPS mode. It may also occur without UPS (when there is no power). It can work all day and then turn off every couple of minutes. That is, randomly.
I updated the firmware (the problems started right after that), turned off eco mode, tried to increase the AC load - it didn’t help. Power lifting never used.
90% time used Silent charge and ~last month Standart.
