is made with a dedicated circuit breaker rated for the
appropriate current back feed rating.
230.82.6: The type of equipment connected to the supply
is listed, with subsection six identifying solar electric
systems as permissible.
All components within a UL 1741 compliant inverter must pass
evaluation spacing, voltages and currents that the inverter is
rated for. The UL 508 standard, industrial control equipment,
auxiliary devices has provisions for testing manually operated
switches. The integrated switch passed the UL508 standard
under the file E304888 for use within a UL 1741 approved grid
tied inverter. The switch was tested 6000 operating cycles at
the nominal AC and DC voltages and currents as noted in table
one below. Additional operating cycles of 4000 resulted in a
total of 10000 successful operating cycles. The switch was de
constructed and evaluated under a pass fail criteria.
As referenced in the NEC, subsection 690.17, the switch must
meet applicable voltage and current ratings. The AC and DC
switch ratings are detailed in this table:

The disconnect solution offered by KACO new energy complies
with all applicable NEC, and UL1741 requirements. The use of
an integrated disconnect with the inverter is potentially safer
due to less electro mechanical connections. The only require-
ment which would necessitate an individual disconnect would
be the specific ruling of the utility requiring a UEDS.
Figure 5.4: DC/AC and night switch, GFDI fuse
The GFDI fuse is located on the right side of the connection
box. When a ground fault occurs this fuse will open causing
the inverter to shut down and indicate a fault. Replace only
with the same type and rating fuse. The fuse is a fast-acting
600 V

The night time start switch is located on the right side of the
connection box. Press and hold the start switch for up to 5 sec-
onds to wake the inverter when there is no DC input voltage.
This allows the user to display the power that was produced
during that day.
