Hi, I have a EB3A for a while and it had been working fine. Today I attempted to turn on the DC and it wouldn’t turn on. I initially thought I had left it on for a day or two and it simply drained. I then plugged it into AC and it is at 100%. An message of “short” in red appeared in bottom left of screen. If I remove it from AC the whole system shuts down and is totally dead? Anyone know of a fix or has then become a brick?
Hi @RickO, We are deeply concerned about the issue you have raised.
The issue lies in the inaccurate SOC of the EB3A, which mistakenly believes it is 100% charged and therefore refuses to continue charging, while in reality, it is over-discharged.
Please plug the EB3A into the AC home grid, and charge until it is 100%.
After that, please turn on the AC and DC output of the EB3A. After 30 minutes to 1 hour, the EB3A will drop from 100% to 99% due to self-consumption.
After the SOC of EB3A drops to 99%, please disconnect EB3A from the home grid to see if the EB3A can be turned on normally. If so please AC charge the EB3A again.
Normally, the EB3A will work well then, and please tell us the EB3A’s SN number, DSP, and ARM version, we will push the new firmware to avoid this problem happen again.
