Ordered the original AC300/B300 combo back in March 2022. Unit would charge but constantly got 021 errors (Grid Input Over Current). Unit would charge at ~1700W then drop to 0W and error out, but would continue the cycle till charged.
Got a replacement a few days ago and I have the same problem. It is not producing as many errors, but within a couple of hours I got 4 021 errors. Two of the errors had a recorded time 12 hours in the future. Date/time on unit is correct so not sure where that came from.
It sounds like the AC300 has a known problem with “Grid Input Over Current” and “Grid Input Under Current” errors. If this true? I am not likeing having to replace this unit a second time.
