Reactive Power a bit high?

[BenW]

I have a SolarEdge SE7600HD inverter with 6.88kw total in module output. Grid tie and ground mount. I have seen on days where the inverter is putting out 5kw and VARs have been over 500. The inverter is set at CosPhi at 1. Places I have read says that the VARs may be due to harmonics. 500 VARs seems mighty high. I wouldn't be alarmed at 200 or so. Any suggestions? Thanks!
