[RE-wrenches] Radian Question

[drake.chamberlin at redwoodalliance.org]

Hi Jay, 

The inverter won't even connect to the grid. It stays in the state where
it is sampling the grid, AC in light blinking. 

Is the default high voltage for the nominal 240 V 280? (IE 140 V X 2). 

Thanks for your help.
