AC wiring WITHOUT an Inverter Subpanel –
This wiring configuration has the AC
input to the inverter coming from an AC source directly. The AC must then be protected by a
branch AC breaker or fuse, see Table 1-1 for fuse recommendations. The AC output is
routed to the main AC panel which is protected by AC circuit breakers.
IMPORTANT:
It is important to note the generator must have its own neutral bonded to
ground. If the generator’s neutral is not bonded to ground, a bonding jumper must be
installed. In this case, the main AC panel must not install a permanent neutral to ground
bond.
STEP 6: Connect the DC input wires
CAUTION
–
Proper polarity must be observed here. Ensure positive is connected to positive, and
negative is connected to negative. Perform this observation at the inverter and the battery.
Reversing this connection will damage the inverter and will invariably be detected by the
manufacturer.
WARNING
: Fire hazard –
Proper wire must be used in all connections. The temperature
rating of the wire must be at least 75°C. All connections must be snug, loose connections may
overheat.
The procedure below will illustrate how to connect the battery leads to the terminals on the DC side
(back of the inverter).
Figure 1-5
below shows the rear of the inverter. Keep the cable lengths as
short as possible. Also make sure the cables are rated to a current at least equal to the rating of the
circuit breaker or fuse used in line with the cables. It is important the cables are insulated to the
correct voltage as well.
Routing DC cables through an electrical distribution panel or battery isolator will result in an
undesired, additional voltage drop.
