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 (SOL30UC12V) rechargeable battery [b] (not incl.) or a 24V

(SOL30UC24V) rechargeable battery [b] (not included) to connections [8]. Use the

correct polarity!

Note: use multi-core insulated copper wire of at least 6mm² and strip ±5mm.

• Then connect a solar panel [a] (not incl.) to connections [11]. 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 [d] (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!

• When connecting an AC load [e] (not incl.), install a suitable DC-to-AC convertor [c]

(not incl.) between battery [b] and load [e].

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 [a], then the load [d or e]

and finally the battery [b].

• Note that shorter connection wires will reduce power losses.

Protection modes

• 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 a

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.

Use

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

to load (B) or charging current from solar panel to battery (C). Use switch [2] to

scroll through the display modes, refer to the icons on top to know what is being
displayed.
