Solarific Posted November 15, 2021 Report Share Posted November 15, 2021 Does anyone know if PVSOL is able to model DC couple battery energy storage systems? In the UK DNOs regard AC coupled BESS inverters as generators and DC couple BESS can also make use of DC power shaved off at peak generation by undersized AC inverters Quote Link to comment Share on other sites More sharing options...
developer_mh Posted November 17, 2021 Report Share Posted November 17, 2021 Dear Solarific, yes, in PV*SOL you can also use DC coupled battery systems. There are three kinds of coupling: AC coupling (coupling takes place on the AC side, after the PV inverter) DC intermediate circuit coupling (coupling takes place inside the PV inverter, in the DC intermediate circuit, i.e. before the DC/AC stage) DC generator coupling (coupling takes places on the DC string, before the PV inverter) See more information and grafics here: https://help.valentin-software.com/pvsol/en/calculation/battery-systems/#type-of-coupling Hope that helps, kind regards, Martin Quote Link to comment Share on other sites More sharing options...
