2.5 Protection Circuitry and Controls
To meet relevant codes and standards, the Solis U.S. single phase inverter line is
equipped with protective circuitry and controls. These include Arc Fault Circuit Interrupter
(AFCI) and Anti-Islanding Protection.
Arc Fault Circuit Interrupter AFCI:
Edition 2011 of the National Electrical Code®, Section 690.11, requires that all PV plants
attached to a building are fitted with a means of detecting and interrupting serial electric
arcs in the PV wiring and array. An electric arc with a power of 300W or greater must be
interrupted by the AFCI in the time specified by UL 1699B. A triggered AFCI fault may only
be reset manually. After clearing the source of the fault, the AFCI can be deactivated via
the inverter front panel interface.
Anti-Islanding Protection:
Anti-Islanding is a condition where the inverter cease to produce power when the grid
is not present. Circuitry, along with firmware, has been designed to determine if the grid is
present by adjusting the output frequency of the inverter. In the case of a 60Hz resonant
system where the inverter is partially isolated from the grid, the inverter programming can
detect if there is a resonant condition or if the grid is actually present. It can also
differentiate between inverter’s operating in parallel and the grid.
