5. Installation

• Mount the regulator in a cool and ventilated, but dry location using the 4 mounting

holes [6]. Use M4x20 screws (not included) for easy mounting.

• First connect a 12V rechargeable battery (SOL30UC12V, not included) or a 24V

rechargeable battery (SOL30UC24V, not included) to connections [8]. Use the
correct polarity!

• Then connect a device or appliance (not included) to connections [9]. Make sure

the connected load is in accordance with the specifications of this regulator and
switched off. Use the correct polarity!

• Finally connect a solar panel (not included) to connections [11]. Make sure the

connected solar panel is in accordance with the specifications of this regulator. Use
the correct polarity!

• Verify whether all connections are tight and secure.

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 short connection wires will reduce power losses.

6. Use

• LCD [1] can show either battery voltage (A), discharge current from battery to

load (B) or charging current from solar panel to battery (C). Use switch [2] to
scroll through the displays, refer to the icons on top to know what is being
displayed.

• Use the Load on/off switch [3] to switch the connection to the load on or off.

When the icon is shown in the display, power is send to the load, unless the
regulator is in over-discharge protection mode.

• Over-discharge protection mode. This mode will be enabled when the battery

voltage becomes too low. The power to the output connectors [9] 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 [7] 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 o

current of more than 30A.

• 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.
