Hi All, I upgraded an old clients' off-grid system about five years ago to a Schneider XW6848+ and 2 Blue Ion 2.0 cabinets (32kWh). When the batteries were moving toward full, if the charge rate was on the higher side via generator or solar (AC coupled w/SolarEdge 6kW and DC coupled with an FM 80), they would start to get pulsating lights similar to symptoms of other older inverters when using a generator for charging. The solution for this pulsation has usually been to kick back the AC charge amperage just enough so the pulsating calmed down to a tolerable inconsequential level. And that worked in this case as well. However, a few weeks ago, the pulsating became more noticeable and has now become fairly intolerable. To my knowledge, no settings changes we made within the previous year, and these clients would be loath to make any changes, so I doubt there were any. More puzzling is the pulsating has started to happen at seemingly random times not related to charging. It happens at night or pre-dawn mornings without the generator, or during the afternoons with solar charging. And it is getting progressively worse. Anyone have any thoughts on why that would start getting worse now? Howie
