RS 450/200 - Solar Power Total Difference Over 10kW

[Tekidan]

The RS MPPT 450/200, when the solar is above 9kW the difference in Total power is always different / out and locks of at 10.58kW on the VRM, but on Victron Connect the power would be 11.5kW. I have attached a screen shot of all 3 power readings from a remote PC. I understand there will be latency.

Would this difference effect DESS & data on the VRM slightly?

No Rush to look in to it, just something I have noticed with the 450/200 when I have oversized the PV.

Potentially the difference between the pv power and whats actually being sent to the battery (battery watts), i.e The system losses in the 450/200 conversion. You can create a custom vrm chart tracking pv power and battery watts to determining if that’s what you are seeing.

The rs450/100 and 200 have significantly more loss than a 250/100 or 150/35 for example, as per the spec sheet:
