CodrinSomesan Posted March 14, 2022 Report Share Posted March 14, 2022 Dear experts, please note that my version of PVSOL dose not let me to configure the HUAWEY 8 KTL inverter to use 2 strings. Is this happening just to me? How can I solve this problem? IS a software problem? Thank you in advance. Best regards. Quote Link to comment Share on other sites More sharing options...
Jimmy Posted March 14, 2022 Report Share Posted March 14, 2022 Hi Codrin, This is probably because you're using panels that have significantly higher current than SUN2000 - 8 KTL is specified to handle as they have a max input current per MPPT of 11 ampere and your panels probably have 12,5-13 ampere under STC. Huawei really hasn't kept up with the changing times with their inverters. PV*SOL doesn't like this but If you're confident that the solution is fine you can create a copy of the inverter and input higher max amps for the inverter and get a somewhat close approximation to how much energy will be produced (Note that I'm not advocating this and that I'm not associated with PV*SOL). Be careful if/when exceeding the maximum input current per MPPT and make sure that you know what you're doing or you might burn the inverter. Personally I'd go with other panels or inverter.

CodrinSomesan Posted March 14, 2022 Author Report Share Posted March 14, 2022 Thank you very much, I spoke with HUAWEI directly and it looks that the inverter suports without any problem this current. Thank you again. Best regards Quote Link to comment Share on other sites More sharing options...
developer_mh Posted March 15, 2022 Report Share Posted March 15, 2022 Hi Codrin, in addition to what Jimmy wrote, you can set the maximum allowed exceedance of the input current in the configuration limits dialog: Hope that helps, kind regards, Martin 1 Quote Link to comment Share on other sites More sharing options...
