WIRING CONNECTIONS

To protect the Battery and the Solar Panel, we strongly recommend that you place a
40A inline fuse for ZS-30A (60A fuse for ZS-40A) on the positive wire on both the
“Solar” and “Battery” Circuits. (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.

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.

1, Using the Terminals supplied, crimp the terminals on your Solar Array wires and
connect to the Solar Panel like shown.

2. Using the Terminals supplied, crimp the terminals on your Battery wires and
connect to the Battery like shown.

When the connections are completed, the Solar Controller will start working
automatically.

OPERATION - LCD DISPLAY

Please check your battery manufacturer's specifications to select correct battery type.
The unit provides 6 battery types for selections: LiFePO4, LTO, Gel, AGM, WET
(conventional lead acid), and Calcium.

Press BATTERY TYPE button and hold for 3 seconds to go into your battery type
selection mode, the battery type you select will be shown on the LCD meter, the
default setting is AGM Battery; the controller will automatically memorize your battery
type setting.

Caution: Incorrect battery type setting may damage your battery.

When the controller powers on, the unit will run self-qualify mode and automatically
show below items on LCD before going into charging process

Self-test starts, digital meter segments test

Indicates the solar panel connected.

After going into charging process, the LCD displays the charging statues as below:
Press VOLT / AMP button in sequence, the LCD will display in turn with

Battery Voltage, Charging Current, Charged capacity (Amp-hour) and Battery
Temperature (if external temperature sensor connected)

Display in the day time-

Q

The VOLT / AMP button can be changed at any time during charging process.

You also can visually monitor your battery charging condition for each battery; there is
a LCD bar to show the percentage of charge, you can easily see the battery is charged
to 25%, 50%, 75% or 100%.

The LCD also can be treated as an independent voltage meter or thermometer.
A voltage less than 11.5V Volts indicates that the battery is discharged and needs
re-charging.

CHARGING STAGES

The unit has a 5-stage charging algorithm.
Soft Charge (Level 1) -Bulk Charge (Level 2)-Absorption charge (Level 3) —
Equalizing Charge* (Level 4) - Float Mode (Level 5)

Level 5

_o—Level 1

Soft Charge- When batteries suffer an over-discharge, the controller will softly ramp
the battery voltage up to 10V.

Bulk Charge-Maximum current charging until batteries rise to Absorption level
Absorption Charge-Constant voltage charging and battery is over 85%.

Equalization Charge*-Only for WET battery or Calcium battery type, when the battery
is deeply drained below 10V, it will automatically run this stage to bring
the internal cells as an equal state and fully complement the loss of
capacity. (LiFePO4, LTO, Gel and AGM battery do not run Equalization
charge)

Float Charge-Battery is fully charged and maintained at a safe level.
A fully charged Lead acid battery (GEL, AGM, WET battery) has a
voltage of more than 13.6 Volts; A fully charged LiFePO4 or LTO battery
has a voltage level of 13.4V.

OPTIONAL EXTERNAL DEVICE

The controller provides two optional devices (excludes in the packaging box).

TEMP. SENSOR L REMOTE

FOR BATTERY

Optional external Battery temperature sensor:

As an option, the unit provides a port to connect the external battery temperature sensor;
if the external battery temperature sensor is connected, the unit will optimize the charging
performance subjected to the battery temperature detected and also provide the battery
over temperature protection, in some cases, if battery over temperature occurs, the
controller will automatically stop charging.

Optional external Remote display meter:

As an option, the unit also provides a port to connect the external Remote display meter
for some special location needed. The display content on the Remote meter is same as
the display on the controller.
