ASSEMBLY (Continued)
5. GRID (UTILITY) CONNECTION
There is an AC (Grid) circuit breaker in the distribution box. This will
ensure the inverter can be safely disconnected during maintenance and
is fully protected from overcurrent of AC input.
Installing an essential load panel provides backup power to connected
circuits. There are two interlocked AC breakers to the essential loads
inside the distribution box. One AC breaker labeled “FROM INVERTER” is
for normal inverter operation. The other breaker labeled “FROM GRID”
bypasses the “AC GRID” breaker and connects the essentials loads
directly to the “Grid Input” terminals.
Note: If the inverter needs to be repaired this breaker can be used to
supply the essential load when the inverter has been taken off-line.
This bypass can also be used while a customer waits for Permission to
Operate from their utility or local Authority Having Jurisdiction.
