Outback Radian Grid Zero Mode
I just got my Radian GS4048A wired into the house through a sub panel and I want to try out the different operating modes but I'm having trouble getting Grid Zero mode to work. The Radian should use battery power until the batteries reach a low voltage set point or a pre-set load limit and then it calls on the grid for assistance. When I turn the mode on it just passes through grid power and doesn't invert. Mini Grid is operating as I would expect where it uses battery power until it drops to a set voltage and then it switches to grid. Anyone with a Radian know if there is another setting that has to be on or off to get the Grid Zero mode to funtion? I'm sure there is something simple that I'm missing.
