Hi Rob, I sent you a message as private message in this forum. Best regards, Frederik

Hello Rob, I'd be glad to investigate the matter. Might it be possible to send me the project file(s) via private message? And please tell me the exact versions of PV*SOL (e.g. 2018R8) you used for the simulations. Best regards! Frederik

Hello Anders, we checked several data sheets from saltwater battery manufacturers to fit our simulation model. Due to the lack of sufficient data we didn't implement a discretely defined model yet. Since saltwater batteries tend to show a similar behaviour as lead-acid batteries (voltage), it is possible to approximate them energetically at least using lead-acid batteries. It is possible to substitute both saltwater and redox-flow batteries using the lead-acid model considering the data you named above. Being able to compare simulation results to measured data is recommended Luckily we have access to measured data of one redox-flow battery in the field, so it seems possible to generate a discrete model in the future. So far I'm disillusioned by the energy efficiency and I strongly recommend to ask the manufacturer for measured data preventing you from overrating redox-flow model substitutes**. If you have further questions feel free to ask! Best regards! Frederik EDIT: **It is possible to regard losses due to hydraulic technics via raising the self-discharge factor.
