    Solar cathodic protection

    Cathodic Protection Unit (CP) CP Unit is a specialised power conver ter which provides DC
    current to metal pipelines, storage tanks, bridges, or other exposed equipment to cancel the effects of natural chemical corrosion.
    The CP operates directly from storage batteries common to photovoltaic systems and is equipped with a low voltage shut-down feature to
    prevent battery damage. It is suitable for use in systems of either positive or negative ground.

    The Solar Cathodic Protection Controller is designed for trouble-free


    service in all environments and includes many special features which
    make it easy to operate and maintain in the field. Solar module

    Power consumption and heat generation are minimised in the CP


    since efficient solid state circuitry is used instead of ballast resistors
    typical of earlier cathodic protection units.
    The power circuit contains no moving parts to wear out or break down.
    Quality digital voltage and current meters provide output monitoring Ground level Solar cathodic protection
    which facilitates field adjustment. Recalibration can be performed in controller and battery
    minutes without special tools or meter equipment.
    (-)
    Since corrosion protection systems normally operate in remote,
    Pipe (cathode)
    unattended sites, they need to be protected from common events that
    make them fail such as: lightning exposure, battery damage, and short
    circuit.

    Protective current
    Our dual transient protection network will suppress electrical spikes
    and surges that normally damage field equipment. If the storage (+)
    batteries become discharged due to cloudy days or photovoltaic
    system failure, the CP Unit will automatically shut down, preventing
    excessive discharge whilst protecting the battery from permanent
    Anode
    damage and costly replacement.
    Our built-in circuit breaker prevents damage to the CP and other
    components, should the output leads become shorted to one another.
    To help reduce overall system cost, the CP includes adjustable current Features:
    and voltage outputs. • Complete weather protection
    Standard photovoltaic modules can be used and the CP output • Easily mounted
    adjusted to the desired level. • Protection from damage
    • Solid state
    • Easy calibration

    Applications:
    • Metal pipelines
    • Storage tanks
    • Bridges
    • Exposed metal structures
