SolarEdge System Design and the NEC
Grid failures may cause photovoltaic inverters to generate currents (“short-circuit currents”) that are higher than the maximum allowable current generated during normal operation. For this reason, grid

UN-BUS and UNB-BUS Alarm : Solis North America
The UN-BUS fault occurs when the inverter detects abnormally low DC voltage on the internal DC bus bar. This can also happen if the inverter experiences an internal failure.
