- I have just installed a 3 phase ESS system with 3 quattro 8000's on a 100 amp supply and found it impossible to get hold of a Em24 or alternative to use with CT clamps.. Carlo Gavazzi UK told me today it would probably be April by time they have the parts and have started shipping them..!(That is a long time to wait!) No one has any thing in stock...Is their an alternative or is it possible to make another meter work for 3 phase victron users?
