5. Installation
Mount the regulator in a cool and ventilated, but dry location using the 4 mounting
holes. Use M4x20 screws (not included) for easy mounting.
First, connect a rechargeable battery [b] (not incl.) to connections [5]. Use the correct
polarity!
Note: use multi-core insulated copper wire of at least 6mm² and strip ± 5 mm.
Then connect a solar panel [a] (not incl.) to connections [4]. 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 [6]. 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.
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.
