Behzad Posted May 22, 2014 Share Posted May 22, 2014 Inverters usually have a nominal AC power (nameplate), and a maximum AC power. I need to limit the inverters so not to exceed the maximum AC power, but I don't have any success. In this case, the inverter I am using is SMA Sunny Central 800CP-US. I have changed the maximum AC power from 880 kW to 800 kW, and also changed the maximum AC current to a value equal to Nominal AC current (which i 1283 A). But I still exceed the inverter output by 0.5 kW on many occasions during a year, and thus get higher MWh/year than expected. I am aware that there is a power limitation option, and it is ticked in my case. Any suggestions on how to overcome this issue? Thanks Link to comment Share on other sites More sharing options...
