Boris Posted December 12, 2016 Report Share Posted December 12, 2016 Dear Team: I need to limit the feed-in power at the conection point and I don´t sure if the Máximum feed-in Power Clipping is the tool for that. For example, if I have a 100 kW PV plant for use in own consumption and I have a feed-in limit of 25 kW, then would I have to put the Máximum Feed-in Power Clipping in 25% of PV Power at the feed in point? Thanks a lot. Regards, Boris Quote Link to comment Share on other sites More sharing options...
developer_mh Posted December 13, 2016 Report Share Posted December 13, 2016 Hi Boris Yes, that is exactly the right option to choose. The Maximum Power Clipping percentage always refers to the installed PV power on the DC side. So if you have 100kWp installed and need to limit your feed-in into the grid to 25kW (on the AC side), you set it to 25%. Whether you clip the power after the inverter or at the feed-in point only really matters if you have loads/batteries/e-vehicles in your system. Energetically of course the best option is to limit the feed-in power at the feed-in point, but not all inverters are capable of doing so.

Habibullah Posted October 11, 2020 Report Share Posted October 11, 2020 Hello Sir/Madam If I feed all the generated power to the grid, in this condition I should not mark the Maximum feed in power clipping, is it true? Quote Link to comment Share on other sites More sharing options...
developer_mh Posted October 12, 2020 Report Share Posted October 12, 2020 Hi Habibullah, yes, this is correct. Kind regards, Martin Quote Link to comment Share on other sites More sharing options...
Dinko Posted April 1, 2021 Report Share Posted April 1, 2021 HI, I put 31,86 kW on DC side and 71%, because i havent to exceed 22,5 kW on AC side. I get cca 48000 kWh per year. That is in PVSOL Premium. On SMA tool I put 22,5 kW limitation and I get 43000 kwh per year. When I calculate on PVSOL online I get 44132 kwh. On PVSOL online i can't limit.

Dinko Posted April 1, 2021 Report Share Posted April 1, 2021 Do I something do wrong? All calculations are with same SMA inverter, and Luxor 320W panel. Quote Link to comment Share on other sites More sharing options...
developer_mh Posted June 8, 2021 Report Share Posted June 8, 2021 Hi Dinko, sorry the for the late answer. These simulation results are very hard to compare, since all tools use different input data, e.g. climate data, different algorithms to model the system components and so on. PV*SOL on you computer and PV*SOL online use the same algorithms, but at the moment the online version uses climate data from an older version of Meteonorm. This will be updated soon.
