The unique marine shore power connection system
The SmartPlug is a revolutionary shore power system designed to provide greater protection against loose connections and corrosion – the leading causes of shore power failure and fires.
The marine range includes inlets, couplers and shorepower cord sets. The shorepower inlets are available in both stainless steel and non-metallic finishes, 30A and 50A; with matching shorepower cord sets up to 15m.
For those wishing to change an existing shorepower set to the SmartPlug system there are also 30A and 50A couplers available with straightforward video instructions (see below) on how to change them.
What makes SmartPlug different to traditional shore power connector?
- 20x more electrical contact than the old twist type connector
- Multi-point locking system
- Solid sleeve connection
- Triple weatherproof seals
Legacy design not designed for today's electrical loads
Contrary to popular belief, the #1 cause of shore power failure and fires is not electrical shorting, but rather overheating caused by poor electrical conductivity.
The problem with the original system:
The shape of electrical pins allows for very little contact area, and the pins themselves are also largely responsible for bearing any physical stress placed on the cord (from constant movement of the boat, someone tripping on the cord, etc.). This results in the pins working loose, further lessening the precious little contact area they had to begin with.
Furthermore, such loose connections allow for moisture intrusion and ultimately corrosion of the pins. Arcing occurs and the connection heats up, scorches, and in some cases, catches fire. Because the current draw is unchanged, all of this happens long before a breaker or a GFCI can cut the power. Additionally, the old design can be very difficult to use in low light or hard-to-reach scenarios since the "L'.' shaped pin must first be located and then oriented before connection.
The Solution – SmartPlug has over 20 times more metal contact
This is also safer as the increased amount of metal contact eliminates overheating

Safe, Simple and secure
No twisting! Self cleaning push-in design.
30 Amp plug features
LED Power Indicator
Two blue LEDs illuminate to indicate an active power source.
Locking feature
Dual locking side levers snap into sides of inlet housing.
Connector body shape
Sleeve design fits snugly within inlet, removing all tension from pins & clips.
Weatherproof
Face gasket seals against inlet sleeve to eliminate dirt & moisture exposure on electrical pins.
About Us
Manufactured In the UK
We design and manufacture a wide range of products in our factory in the UK. We have invested in state of the art cable processing machines to allow us to automate many aspects of our production, guaranteeing quality and consistency. Our engineering department use advanced mechanical and electrical design tools to drive this process, and we use computerised testing machines to speed up loom construction and validation. We also have in-house facilities to laser cut and engrave control panels, along with 3D printing for prototyping components. None of this manufacturing would be possible without a skilled team of staff, with years of experience in complex builds.
Partners
We work with leading international manufacturers and distribute their products in order to supply our customers with a complete electrical power, monitoring and control solution. We work with some of the biggest names in each market sector and have established ourselves as a key supplier bringing new ideas and technical updates on a continual basis.
Support
During your project, Energy Solutions will be with you every step of the way, from initial consultation to final implementation. Our engineering team will provide comprehensive drawing packages, both 2D and 3D as appropriate, and will assist during commissioning phases. Post-project, our service team will take over to provide ongoing support in the field.
