SolarEdge DC limit

[solarDG1470]

We are using the SE50KUS (208V)  inverter.  Getting an error when i assign 2 strings (1.39DC/AC) ratio to it.  Error says i cant go over 1.35 dc/ac ration. this does not seem right and i cant find out how to change it.

Hello, have you tried changing it from the project settings? Also what is that menu? where did you access it from?

For SolarEdge system there is two different advanced parameters limiting the Pnom ratio, one for inverters with less than 25kW nominal power, on for more than 25kW.

Since the 50kUS is set to 16.7kW (1/3 of the physical inverter), the <25kW parameter.

Please check these parameters in the advanced parameter menu (Settings => edit advanced parameters)

You should be able to simulate your system if you change the parameter 404 to something higher than 39%
