MARINE BOAT AUTO ELECTRICS SHROPSHIRE

Marine low voltage electrical equipment has specific weather proofing requirements to prevent corrosion

Battery Banks

Marine applications such as Narrowboats may have multiple battery banks including Engine Starter Battery and Leisure Batteries for Domestic power supply.

Battery charging from engine driven alternator may be as simple as a split charge relay setup or may make use of complex battery charge controllers depending on number of batteries, battery type, charging parameters etc.

Preference of charging system controller becomes a matter of personal opinion with premium brands including Victron Energy and Sterling

Battery banks may be recharged by off grid technology when cruising, or by shore power supply when moored if available.

Solar Panels

Solar panels are now commonly fitted to marine applications such as live aboard narrowboats

Typical wiring may include an isolator switch to disconnect the Solar panels from circuitry

Solar panel PV systems are generally wired through a MPPT device then to battery banks. The MPPT device acts to regulate charging current and voltage to each battery to achieve optimum charging parameters.

Wind turbines

A small scale wind turbine may be used to supplement battery charging on Marine applications

Battery to Battery Chargers

Battery to battery chargers provide a means of regulating charging current in split charge systems

Shore Power

Shore power is provided by connection of a power cable to remote land based power supply connection

The mains shore power connection may be wired to a battery charger system to recharge starter and auxilliary batteries

Rotating Electrics

MARINE STARTER MOTORS

Starter motors for boat applications can be supplied please enquire.

MARINE ALTERNATORS

Marinised aor Standard alternators for boat applications can be supplied. Please enquire.

Travelpower

The travel power systems utilise an engine driven alternator with three phase output wired to an electronic controller with power output facility

Generator

Standalone onboard generator may supply power directly

BILGE PUMPS

The function of the bilge pump is to move water from the bilge (internal hull lower area) of your watercraft

A seperate bilge pump for each compartment is recommended

Be aware that bilge water may become contaminated by hydrocarbons from oil and fuel leakage therefore the bilge pump system may be designed to include filtration to reduce pollution.

We supply a range of Submersible Bilge Pumps for leisure boat applications including:

  • Part No HC070154 : MARCO model UP500 12V Compact Submersible Bilge Pump with up to 32 Ltr/ min flow and up to 4 metre head featuring ABS plastic housing which can be dismantled for cleaning, Stainless Steel pump shaft with ceramic seal. Voltage : 12v DC | Current Draw 5 Amps | Price from GBP 25.00 pounds nett

  • Part No HC070155 : MARCO model UP1000 12v Compact Submersible Bilge PPump with up to 63 Ltr/min flow and up to 4 metre head featuring ABS plastic body which can be dismantled for cleaning, Stainless pump shaft and Ceramic Shaft seal. Voltage : 12v DC | Current Draw 10 Amps | Price from GBP 40.00 pounds nett.

  • Part No HC070156 : Marco model UP1500 12v Compact Submersible Bilge PPump with up to 95 Ltr/min flow and up to 4 metre head featuring ABS plastic body which can be dismantled for cleaning, Stainless pump shaft and Ceramic Shaft seal. Voltage : 12v DC | Current Draw 20 Amps | Price from GBP 64.00 pounds nett

FLOAT SWITCHES

Fitment of float switches provides automatic control of the bilge pump when water level in the bilge area rises.

Masthead, Port and Starboard Navigation Lights

Headlights Worklights SpotLights SidelightsTowing Lights

Essential for night time operation and for narrowboats travelling through tunnels on the canal system

Navigation lights indicate the position and direction of travel of a watercraft

Red : Port

Green : Starboard

Nav lights must meet approved standards and collision regulations (colregs 1972 annex 1) otherwise marine insurance may be voided in the event of a collision.

Cable glands and seals

Prevention of water ingress from tracking along cable entry points, also to provide security and prevent chaffing.

Fuses

Megafuses and Midi fuses

ATO blade fuses

Circuit breakers

Galvanic Corrosion and Isolation

Residual currents may conduct through water between metal components of watercraft such as Narrowboats. Dissimilar metals in electrolyte crate electrolytic action. In doing so electrolytic action gradually removes metal from the hull and propellor by galvanic corrosion. A galvanic isolator may be fitted to reduce this effect. Anodes may be affixed to the hull which deteriorate before the hull due to the reactive composition of the metal anode. The metal used for the sacrificial anode (usually Aluminium, Zinc or Magnesium) has lower potential than the 'cathodic' hull thus losing ions to the electrolyte
