Hello,
 
	I am trying to simulate the redox flow battery "VoltStorage Smart" with the information provided above and by using the product's data sheet.
 
	However, the "level of self sufficiency" of 42.1 %  seems too low compared to when  I choose other battery systems with similar capacities (e.g. BlueSky or BYD with more than 50 %).
 
	Does anybody have an explanation? Maybe my model needs to be adapted?
 
	 
 
	Kind regards
 
	Hubert
 
	EDIT: the efficiency is too high. It should be 0.75 according to the CARMEN online database. Yet, changing it doesn't affect the outcome much.
