Current/OS on 350V or 700V LVDC
The voltage levels are nominal voltages this is excluding the droop range defined by the Current/OS to define the State Of Balance (SOB) of the grid.
The nominal voltage tolerance can be maximal 1.4%. The Grid is isolated from the AC grid and have it's own grounding system.
Why 350V DC
Why 700V DC
Voltage levels and applications
There is a lot of discussion about the correct voltage level. This is not simple. It's important to select a level that is universal and can be used for different application, this is why we selected 350V/700V as the level that has the lowest compromises between the applications.
Low Power DC Grids 350V
