Connect the positive (+) and negative (-) of loads to controller load terminals as shown in
Figure 3-3. The load terminal may exist voltage, connect carefully to avoid short circuit.
An in-line fuse holder should be wired in series in the load positive (+) or negative (-)
wire as show in Figure 3-3. Do not insert a fuse at this time. Confirm the connection
correct and
turn on the power.
If wiring the load connection to a load distribution panel, each load circuit should be
fused separately. The total load draw should not exceed the load rated current of
controller.
Step 3: Solar wiring
WARNING: Risk of electric shock! Exercise caution when handling
solar wiring. The solar module(s) high voltage output can cause
severe shock or injury.
Be careful operation
when installing solar
wiring.
The controller can accept12V, 24V nominal off-grid solar module(s). Grid-tie solar
module(s) may be used if the open circuit voltage of solar module doesn
’
t exceed the
Maximum PV input voltage of the controller.
The solar module(s) work voltage must be equal to or greater than the system voltage.
