To protect the Battery and the Solar Panel, we strongly recommend that you place a
inline fuse on the positive wire on both the “Solar” and “Battery” Circuits. A 15A fuse
for ZS-8A, (As close to the Battery /Panel as possible)
The Solar Controller has 4 terminals which are clearly marked ‘Solar’ and ‘Battery’.
There is a (12V) and earth (GND) terminal for each circuit.
Refer to the wiring diagram below.

please slim the end of wire prior to installation.
1. Using the string wires, screw tightly the wires to the “Solar” terminal on the back of
controller and connect to the Solar Panel like shown.
2. Using the string wires, screw tightly the wires to the “Battery” terminal on the back
of controller and connect to the Battery like shown.
When the connections are completed, the Solar Controller will start working
automatically.
Please check your battery manufacturer’s specifications to select correct battery type.
The unit provides 4 battery types for selections: Gel, AGM, WET (conventional lead
acid), and Calcium.
There is a DIP switch at the back of the solar charge controller, this Dip switch is used
for presetting your battery type. Please refer to Figure 3.1 to make DIP switch setting
for the proper battery chemical; the factory default setting is at AGM battery type.
Note: Once the Dip switch setting is finished, do not freely change the DIP
switch; otherwise it may damage your battery.
Correct Wire Size:
Please refer to the wire size chart
below to determine the minimum
size wire needed for each
connection. This will also ensure
you get the best performance out
of your solar regulator.
