This high-efficiency, waterproof 170W monocrystalline solar charging kit is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications. The solar panel is ideal for flat or curved roofs, such as on boats, caravans, motorhomes, RVs etc as it easily moulds to fit the shape of the roof.

The solar kit includes:

- 170W narrow semi-flexible, textured solar panel made of plastic reinforced with glass fibre (IEC certified)

- 20A high efficiency MPPT solar charge controller with inbuilt LCD display

- Pair of 5m 4.0mm² single core extension cables with MC4 connectors

- 5m 4.0mm² dual-core battery cable fitted with a fuse holder, 15A fuse and 8mm ring terminals

170W narrow semi-flexible solar panel:

This solar panel has a textured surface that reduces the reflection of light whilst maximising the absorption of light from every possible angle. This ensures high performance of this solar panel in low light or cloudy conditions, or when the light falls at an angle (morning, evening or winter times). The fibreglass plastic used in this solar panel is very strong and durable. Soft and sealed edges of the solar panel make it resilient to mechanical impact on the sides and help avoid long term delamination. These Austrian manufactured solar panels are made to the highest European quality standards and are fully waterproof with a high resistance to salt water environments which makes this solar panel perfect for boats and marine applications.

High efficiency MPPT controller:

The 20A 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 safety functions including protection against: reverse current at night (from the battery back to the solar panel), over-charging and deep discharge, over voltage, over load, short circuit and reverse polarity protection. The controller also has self-diagnostic capability and highlights any system errors using advanced fault-targeting technology. 

The built-in LCD screen shows real-time charging parameters such as voltage, current (separately for solar panel / load), battery state of charge, accumulated charge and discharge energy. The easy to use buttons allow the user to manually select the battery type (sealed, flooded or gel) and program load settings (e.g. set timers for lighting, fans, pumps etc).

This controller is compatible with lead-acid (sealed, gel or flooded) and lithium batteries.

Advanced monitoring and programming:

This solar charge controller also features advanced communication technology, which offers the user the opportunity to monitor and program parameters for the controller through various methods:

1) The controller can be connected to a remote meter MT50 with an LCD screen, which displays system performance information and allows the user to manually adjust parameters and load settings

2) The controller can be connected to a Wi-Fi module to create a Wi-Fi network, to which your mobile phone or tablet can connect, in order to monitor or adjust charging parameters and controller settings through a free mobile app (available for Android and iOS users), including setting the charging parameters for lithium batteries.

3) An RJ45 to USB cable can be used to connect the controller directly to your PC / laptop, where parameters and settings can be monitored and adjusted via a free computer program - Solar Station Monitor (Windows-based PCs and laptops only).

Using one of these communication methods, the user will gain access not only to the standard charging parameters already shown via the built-in LCD screen, but also additional information such as min/max voltages, temperature, protection cut off voltages, diagnostics and other information. If required the user will also be able to amend the battery capacity, set charging volts for different charging stages, specify the duration of each charging stage, create a user-defined battery type with charging parameters specific to their battery (if the pre-existing options are unsuitable), and more.

Additional items: 

The solar panel is fitted with 2 x 0.9m cable (4.0mm² cross section) with waterproof MC4 connectors which can be used for easy connectivity to the 4.0mm² extension cable included in this kit, or for linking several panels together. This kit also includes a heavy duty 5m 4.0mm² dual-core battery cable fitted with a fuse holder, 15A fuse 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 panel and therefore delivered in a separate package.

The solar panel in this kit is covered by a 5 year warranty and the solar charge controller is covered by a 2 year warranty. For more information please refer to our Terms and Conditions.

This solar panel comes with a detailed instruction manual which explains wiring and operations (see Documents tab). The solar charge controller also comes with a separate instruction manual which explains settings and operation.

This solar panel is normally fitted to a roof using a suitable adhesive but it 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.
