5. Installation

Mount the regulator in a cool and ventilated, but dry location using the four mounting holes. Use M4x20 screws (not included) for easy mounting.
First, connect a 12 V (SOL30UC12V) rechargeable battery (not included) or a 24 V (SOL30UC24V) rechargeable battery (not included) to connections. Use the correct polarity
Use multi-core insulated copper wire of at least 6 mm² and strip ± 5 mm.
Then connect a solar panel (not included) to connections.
Make sure the connected solar panel is in accordance with the specifications of this regulator. Use the correct polarity!
Finally connect a DC device or appliance (not included) to connections. Make sure the connected load is in accordance with the specifications of this regulator and switched off. Use the correct polarity!
When connecting an AC load (not included), install a suitable DC-to-AC convertor (not included) between battery and load.
Do not short-circuit or reverse polarity of battery, solar panel or load, as this will lead to irreversible damage.
To disconnect the regulator, first disconnect the solar panel, then the load and finally the battery.
Note that shorter connection wires will reduce power losses.

6. Protection Modes

Over-discharge protection mode. This mode will be enabled when the battery voltage becomes too low. The power to the output connectors is cut off to prevent damage to the battery. Remove the load from the connector and wait until the battery is fully recharged.
Over-charge protection mode. This mode will be enabled when the battery voltage becomes too high. The power from the solar panel input connector is cut off to prevent damage to the battery until the voltage drops below an acceptable level.
Over-load protection mode. This mode will be enabled when the load draws a current of more than 30 A.
Load short circuit protection mode. Enabled when a short circuit in the load is detected.
Reverse polarity protection: in order to prevent possible damage the regulator will not function when reversed connecting polarity is detected. Correct the polarity to use the regulator.

7. Use

The LCD can show either battery voltage (A), discharge (output) current from battery to load (B) or charging current from solar panel to battery (C). Use the switch to scroll through the display modes, refer to the icons on top to know what is being displayed.

Battery voltage. Load on/off switch has no function.

Output current from battery to DC-load.

Indicates 0.00 A when load is switched off.

Use the load on/off switch to switch the output current to the load on or off.

Note: In over-discharge protection mode trying to switch on output to the load will fail and a buzzer will sound. When the system recovered from over- discharge protection mode (battery charge level back to normal) press the load on/off switch two times to restart output current to the load.

Charging current from solar panel to battery. Load on/off switch has no function.

8. Troubleshooting

Charging not indicated on display when solar panel is

connected.

Reverse polarity.

Correct the polarity.

Loose connection.

Secure connection(s).

Not enough sunlight.

Reposition solar panel.

No output on load connections.

Load switch off.

Press the load on/off switch.

Battery not connected, loose connection or wrong polarity.

Connect a battery to the regulator, check correct polarity and secure connection.

Polarity load reversed.

Correct load polarity.
