damonl Posted October 19, 2017 Report Share Posted October 19, 2017 Hi, I'm looking to design a purely off grid hybrid PV / Generator system but without batteries and include the SMA fuel saver controller as an energy management system. Can this be done in PVSol? Thanks Regards Damon Quote Link to comment Share on other sites More sharing options...
developer_mh Posted October 19, 2017 Report Share Posted October 19, 2017 Hi Damon, while we haven't implemented the exact control mechanisms of the SMA Fuel Saver, you could do the following to mimic a hybrid PV system: Go to the battery and battery inverter page, select the first cluster in your system configuration Click the "Battery Management" link Disable the battery as good as possible with these settings: It will not be possible to avoid their usage completely, but you can limit their participation quite effectively, so that your load will be covered by PV and diesel only: Hope that helps, kind regards, Martin Quote Link to comment Share on other sites More sharing options...
damonl Posted October 19, 2017 Author Report Share Posted October 19, 2017 Hi Martin, Thanks, it does answer the battery part of the equation but traditional PV Diesel generator systems only really allow the PV system to provide up to 20% of energy capacity. The SMA fuel saver controller increases this capacity to 60% though. I suppose you can't cater for the SMA fuel saver controller though?

developer_mh Posted October 19, 2017 Report Share Posted October 19, 2017 Hi Damon, you are right, these aspects are not implemented in the simulation right now. What do you mean by energy capacity? Are these values a percentage of the instantaneous load (power), or is it in terms of daily or annual energy share? Kind regards, Martin Quote Link to comment Share on other sites More sharing options...
damonl Posted October 19, 2017 Author Report Share Posted October 19, 2017 Apologies, referring to percentage of instantaneous load. Quote Link to comment Share on other sites More sharing options...
developer_mh Posted October 19, 2017 Report Share Posted October 19, 2017 ok, I understand now. No, that is definetely not possible to accomplish right now. But is it never possible to cover the entire load with 100% PV on sunny days with these systems? That seems a bit odd to me... Quote Link to comment Share on other sites More sharing options...
damonl Posted October 19, 2017 Author Report Share Posted October 19, 2017 No, but there is technology that can maximise PV output and minimise the diesel genset load according to the time of day, climatic conditions and demands. Quote Link to comment Share on other sites More sharing options...
AngelaOu Posted March 27, 2018 Report Share Posted March 27, 2018 Look for diesel generator set with ATS, automatic system, controller? Helpful link: http://www.dieselgeneratortech.com/ Quote Link to comment Share on other sites More sharing options...
