Installation of this kit does not require an electrician, however we recommend seeking
help if at any stage you are not confident in your ability.
All wiring and voltages in this kit installation are well under the 120V DC standards for extra-
low voltage (ELV). ELV is an electricity supply voltage in a range which carries a very low risk of
electrical shock.
We are always happy to help guide you through the install, troubleshoot, and answer any questions.
You can contact us on 09 218 5533, or [e-mail].
We recommend reading these instructions in full prior to starting your install.

SOLAR PANEL WIRING
Start by creating two pairs of panels wired together. Connect the positive terminal of one
panel to the inline fuse, then to the negative terminal of the next panel.

SOLAR PANEL WIRING
Run the solar cables to the
32A circuit breakers, and cut
it to length.
DO NOT connect the cable
run to the solar panels until
all solar wiring is complete.
DO NOT connect the cable run to the solar panels yet, as the cables will become live.
Wait until all solar wiring is complete.
Note: We recommend the PV cable to be run inside of a conduit when the cable is run across a roof,
floor, or the interior of a building.
Run the 6mm solar cables from the solar panels back to the 32A circuit breakers, and cut it to length.

Indicator is green, showing the
circuit breakers are switched off.

Ensure the solar cable run is NOT connected to the solar panels, and the
circuit breakers are switched off (showing green, switch down).
Use wire strippers to strip the ends of the solar cable, and terminate them in the circuit breaker by
inserting the stripped end and tightening the screw clockwise. Make sure the clamp inside the
circuit breaker is contacting the metal conductor, and NOT the insulation of the wire.

Ensure the circuit breaker
stays switched off.
Now connect the cable
run to the solar panels.
When the cables have been terminated in the circuit breaker, and the circuit breaker is switched
off, you can now connect the solar panels to the cable run. The circuit breaker must be switched
off when connecting or disconnecting the solar panels from the cable run.
For your safety do not connect or disconnect any solar cables when there is current running
through them.

BATTERY BANK SETUP AND WIRING
Battery Link Cable
When wiring the blue cable ensure that you fully attach each cable at both ends before
moving onto the next.
Wire the remaining set of red and black 25mm cable to the inverter through the C125 circuit breaker.
When running the wires from the battery bank to the circuit breaker, be very careful
not to touch the positive (+) to the negative (-). This will cause a short circuit, which
will result in a spark, and may damage the batteries or the cables.

The battery bank is wired with two 12V batteries in series, this creates a 24V battery bank. The large
gauge cable is used to connect the batteries together and used to connect to the inverter.
Wire the two batteries together from negative to positive with the blue battery link cable.

Wire the remaining set of red and black 16mm cable to the charge controller through the
C63 circuit breaker.

START UP PROCEDURE
The Green LED on the charge controller should flash, and the panel voltage should be around
60-70V in full sunlight. As this charge controller auto-detects voltage, on its first start up it can
sometimes default to 12V, and will give a battery over voltage warning.
To fix this, switch off all circuit breakers in the reverse order of step 15. Then switch them back on.
Switch on the circuit breakers in the following order. First switch on the battery to charge controller
breaker C63. Then the battery to inverter C125. Finally, the panels to the charge controller C32.

The system is now fully functional. The last step is to select the GEL battery charging mode on the
charge controller. Click SELECT until the battery voltage interface is shown.
Hold down ENTER for 3 seconds, then click SELECT until the GEL word is displayed, then press ENTER.
Flick the “ON” switch located on the side of the inverter, and check that all three LED indicators
show green. If any do not show green, consult the inverter manual to identify the fault.
