I have been having issues with inverters dropping out and being erratic. Apsystem Ds3-l i have checked the voltage at 244 and the frequency is 60hz temps are 13C. I can't see any reason they would be shutting down. I was in the EMA app and seen the grid profile is set to North America Canada UL1741 im in Wisconsin I tried to switch to the US but it won't take not sure if this would cause the inverter issue or not.

That happened to me because the AC voltage got too high. The voltage
at the inverter output will rise, higher than where the power company
comes in, due to wiring loss. I had a 9V rise in long loop, had to use bigger
wire to fix it. Check your inverter terminals with varying output. Bruce Roe -
the grid changes a lot and your inverter is set. so it may stop until the grid is back to normalComment
