41 Installation Manual
WARNING: To reduce the risk of injury, use the recommended
cable size above. It is very important for system safety
and efficient operation to use the appropriate cable for AC
connection.
7. ESSENTIAL LOAD CONNECTION
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.

Essential Load (AC Output) Connection
WARNING: Essential load terminals are to be wired to a
separate subpanel. Never connect essential load lines directly
to the main service panel without use of an external automatic
transfer switch. Direct connection of essential loads output to
the grid will result in damage to the inverter.
WARNING: Do not connect essential loads output in parallel
with the grid!
