Ajay Deepak Posted October 23, 2022 Report Share Posted October 23, 2022 Hi, In the case of multiple MPPT inverters, do we need to add a single MPPT Isc or combined Isc data in the below section? In most cases of multiple MPPT inverters, I can see combined Isc data. But this is not relevant for inverter protection. If it is for single MPPT current (Isc), can you add some text mentioning single MPPT Isc in this section? Quote Link to comment Share on other sites More sharing options...
developer_fw Posted October 24, 2022 Report Share Posted October 24, 2022 Hello Ajay Deepak thank you for the input! A maximum short circuit current per MPP is a parameter planned for our upcoming release. Kind regards, Frederik Quote Link to comment Share on other sites More sharing options...
Ajay Deepak Posted October 24, 2022 Author Report Share Posted October 24, 2022 Hi Frederik, Thanks for the quick reply. In addition to this, you may need to add the option to capture the maximum input current per each input terminal. Future, multiple MPPT inverters will have 4 to 5 inputs. So here limiting factor will be the input terminal (connector) current. Example: https://support.huawei.com/enterprise/en/doc/EDOC1100191089/8f97422c/technical-data Quote Link to comment Share on other sites More sharing options...
Ajay Deepak Posted December 20, 2022 Author Report Share Posted December 20, 2022 Hi Frederik, Are you planning to consider this in the development? Regards, Ajay. Quote Link to comment Share on other sites More sharing options...
developer_fw Posted December 21, 2022 Report Share Posted December 21, 2022 Hello Ajay Deepak, this is built into our latest release 2023 R1: https://valentin-software.com/en/products/pvsol-premium/#release-notes Just download the demo and check if it suits your needs. Kind regards, Frederik Quote Link to comment Share on other sites More sharing options...
Ajay Deepak Posted December 21, 2022 Author Report Share Posted December 21, 2022 Hi Frederik, I am referring to below information, capturing maximum MPP current per String (terminal). I can't find this in the new version. In addition to this, you may need to add the option to capture the maximum input current per each input terminal. Future, multiple MPPT inverters will have 4 to 5 inputs. So here limiting factor will be the input terminal (connector) current. Example: https://support.huawei.com/enterprise/en/doc/EDOC1100191089/8f97422c/technical-data Regards, Ajay. Quote Link to comment Share on other sites More sharing options...
developer_fw Posted December 21, 2022 Report Share Posted December 21, 2022 Hi Ajay Deepak Have you had a look at the latest version 2023 R1? When creating new inverter database entries, it is possible to define up to 3 different characteristics for up to 20 MPP trackers Is this what you are looking for? Maybe I am just misunderstanding your request. Kind regards, Frederik Quote Link to comment Share on other sites More sharing options...
Ajay Deepak Posted December 22, 2022 Author Report Share Posted December 22, 2022 Hi Frederik , I think there is some misunderstanding, In future, multiple MPPT inverters will have 3 to 5 inputs. So here limiting factor will be the input terminal (connector) current in addition to maximum Short-circuit current per MPP tracker. Example: https://support.huawei.com/enterprise/en/doc/EDOC1100191089/8f97422c/technical-data Quote Link to comment Share on other sites More sharing options...
developer_fw Posted January 5, 2023 Report Share Posted January 5, 2023 Hi Ajay Deepak, On 12/22/2022 at 1:13 PM, Ajay Deepak said: I think there is some misunderstanding Indeed. For a clearer view into the question it might be helpful to show a small screenshot of the inverter terminal from the Huawei homepage link which you added to your request: So far, we cannot map this behaviour (a max terminal current limiting the sum of string currents) in PV*SOL, you are correct. There might be cases, in which our configuration check is not able to respect those boundary values. On 12/20/2022 at 6:18 PM, Ajay Deepak said: Are you planning to consider this in the development? We definitely are. At the moment I cannot give a date yet. Kind regards, Frederik Quote Link to comment Share on other sites More sharing options...
