I’ve got offgrid 2 clients and they have no issues. They each have a Bolt and can choose the charging rate. They can run it at either power. But only use higher power when they have lots of sun. Older Stacked vfx and Schneider xw, no issues.
I would expect the SW to work, however it’s an odd beast as it’s waveform steps change with load. More load, more steps, therefor cleaner so maybe at lower charge rate it’s not clean enough. As to your issue it could be power factor Being really poor. Can you tell us what inverter, yea 5 years ago is a long time.
