This powerful, waterproof 500W polycrystalline solar charging kit is perfect for permanent outdoor use for charging 12V or 24V batteries in marine applications such as narrowboats, wide beams, Dutch barges, catamarans or other sailing boats. This kit is also suitable for various other applications, including motorhomes, caravans, vehicles, and off-grid back up solar systems.

These 250W solar panels are the largest semi-flexible solar panels available on the UK market and are ideal for flat or curved roofs, as they can easily mould to the shape of the mounting surface. This is our most powerful flexible solar charging kit, and can generate up to 40A charging current when charging a 12V battery. 

This kit will charge a typical 200Ah battery from 0% to 100% in only 5-6 hours of bright sunlight.

The solar kit includes:

  • 2 x 250W semi-flexible, textured solar panels made of plastic reinforced with glass fibre - IEC certified (Austrian made)
  • 40A 12V/24V high efficiency MPPT solar charge controller with remote LCD display
  • A pair of 5m 4mm2 single core extension cables with MC4 connectors
  • 3m of 10mm2 battery cable with a 40A fuse, fuse holder, and 8mm ring terminals

 

2 x 250W semi-flexible solar panels:

These solar panels have an extremely durable fibreglass textured surface that minimises light reflection whilst maximising light absorption from every possible angle. This ensures high solar panel performance in low light or cloudy conditions, or when light falls at an angle (morning, evening or wintertime). 

When the panels are attached to a rigid surface, it is possible to walk on them in soft shoes (to prevent accidental scratches), making this kit the perfect choice for mounting on a boat deck.

These Austrian-made solar panels are manufactured to the highest European quality standards and are fully waterproof with a high resistance to salt water environments.

High efficiency MPPT controller:

The 40A high efficiency MPPT solar charge controller included in this kit uses the most advanced Maximum Power Point Tracking (MPPT) technology to track the maximum power voltage point of solar panels as it varies depending on sunlight exposure and temperature. This technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers.

The controller features a comprehensive set of electronic protection functions such as stopping reverse current at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, over voltage, over load, short circuit and reverse polarity protection. This controller also offers numerous possibilites for system personalisation. For instance, you can specify the duration and voltage of each charging stage, create a user-defined battery type with charging parameters specific to your battery, or personalise the load settings - e.g. set timers for lighting, fans, pumps. Other features include LED indicators, an audible fault alarm and a temperature sensor.

The kit / controller comes with a remote LCD meter with 5m cable. This meter can display the state of charge of the battery and various charging parameters such as voltage and current. It can also record accumulated battery capacity and min / max values reached over time.

This controller is compatible with sealed, gel or flooded batteries and can automatically recognise 12V/24V battery systems.

Additional items:  Each solar panel is fitted with 2 x 0.9m cable (4.0mm2 cross section) with waterproof MC4 connectors, which can be easily connected to the 4.0mm2 extension cable in this kit, or alternatively used for linking several panels together. This kit also includes 3m of heavy duty red and black battery cable (10mm2 cross section) with a 40A fuse, fuse holder, and 8mm ring terminals for use between the solar charge controller and your battery.

Please note: due to our warehouse arrangements, the solar charge controller and accessories may be shipped from a different warehouse to the solar panels and therefore delivered in a separate package.

This product is covered by a 2 year warranty. In addition, solar cells are guaranteed to produce at least 90% of nominal power in 10 years after purchase and at least 80% of nominal power in 25 years after purchase. This warranty is provided by the manufacturer of solar cells. For more information please refer to our Terms and Conditions.

 

 

These solar panels and solar charge controller each come with a detailed instruction manual which explains wiring, operations and settings (see Documents tab).

These solar panels are usually fitted to a roof / deck using a suitable adhesive, but they can also be secured with self-tapping screws, tenax fasteners or even zipping (not included).

Note: this solar charge controller is not waterproof, and should be mounted indoors.

The recommended minimum battery bank capacity for this kit is 200Ah for 12V battery banks, and 100Ah for 24V battery banks (for example, we do not advise using this kit with a single 100Ah 12V battery as the charging current may be too strong).
