negative DC wires and between each DC wire and earth ground.
4.
Attach MC (Multi-contact
or Tyco) solar type connectors to the PV array DC
positive and negative wires. Use red connectors for the positive DC wires
and black connectors for the negative DC wires
5.
Connect PV array DC positive wire(s) to the positive (+) terminal(s) of the
inverter. Connect the PV array DC negative wire(s) to the negative (-)
terminal(s) of the inverter. Each DC terminal on the SPH inverter is rated for
a maximum of 20A DC current. Ensure that the maximum short circuit
current of each PV string does not exceed 20A DC.

When connecting the DC terminals, ensure that the polarity is
correct. Incorrect connection may permanently damage the unit!
Step 4: Test the installation
1.
Remove any protective short circuits applied to the PV array output.
2.
Remove any shade material from the PV panels and ensure that the PV
array is illuminated by sunshine.
3.
Turn on the external DC switch (if fitted).
4.
After connecting the DC

, the message sequence on the LCD display should
be “INV Waiting”
→
“No Utility” and the RED fault LED keeps on.
5.
Fit any fuses removed from the AC supply. Close the AC breaker or switch
and apply AC power to the inverter.
6.
Verify that the inverter starts to work after a short delay. (This may take a
few minutes to verify that the electric grid is stable.)
7.
If inverter works normally, the LCD display panel will show “Working mode”
and power is delivered to the electric grid. If there are any problems refer to
the Troubleshooting section for possible resolutions.
8.
The installation test is complete.
