Thanks but mine did not start up as I expected my unit is a Kstar Hybride inverter I do not have a portal to see what my system is doing, the battery light does not light nor does the backup light up. my installer went bust shortly after my install in 2006 and everyone I have contacted so far has no knowledge of Kstar . It seems there is a lot of installers of panels but a system like mine having batteries engineers are few and far from my house
