This high efficiency 240W 12V dual battery semi-flexible charging kit is perfect for permanent outdoor use to provide free electricity for charging a 12V battery to power various devices for many applications such as in a camper van, boat, shed or farm.

This is a complete 240W solar charging kit which includes:

• 2 x 120W black semi-flexible solar panels with 2 x 1m of special solar cable and waterproof connectors
• 25A Morningstar dual battery solar charge controller
• Morningstar remote LCD meter RM-1
• Waterproof double entry cable gland
• 2 x 5m of 6mm² dual core battery cable fitted with a 20A fuse, fuse holder and 8mm ring terminals
• Pair of 5m 6mm² solar extension cable with MC4 connectors
• Pair of waterproof T-MC4 connectors for easy connectivity
• User manual with detailed installation instructions

2 x 120W black semi-flexible solar panels:

This durable 120W black semi-flexible solar panel, reinforced with fiberglass plastic and a strong ETFE surface, is designed for permanent outdoor use. Made with efficient monocrystalline solar cells, it provides free electricity for charging 12V batteries, ideal for motorhomes, caravans, campers, boats, solar lighting systems, off-grid setups, and backup power systems. It can also supply direct power for voltage-insensitive applications like electric motors or pumps and various grid-tie systems.

Key features include robust fiberglass-reinforced construction, a textured surface for improved low-light performance, and a highly flexible design for curved surfaces. Its black backing ensures discreet, aesthetic installation on dark roofs or vehicles, while its lightweight (2.19kg) and thin (2mm) profile make it suitable for all vehicles. The panel’s waterproof and saltwater-resistant design makes it perfect for marine environments and all-weather use.

The panel’s ETFE coating further enhances its durability, reducing the risk of cracking, delamination, and corrosion while improving light absorption through an anti-reflective surface. Paired with advanced 5-busbar solar cells, it achieves high efficiency, extracting more power from a smaller footprint—ideal for space-limited applications. Its anti-reflective texture maximizes light absorption even in low-light or angled-light conditions, ensuring reliable performance throughout the day and year.

25A Morningstar dual battery solar charge controller:

The Morningstar SunSaver Duo 25A 12V dual battery solar charge controller is a high-quality and powerful solution, widely recognized as the leading dual battery controller on the market. It is ideal for caravans, motorhomes, boats, or systems with two batteries (e.g., an engine battery and a leisure battery). Users can set a charging priority, such as 90% to the leisure battery and 10% to the engine battery. Once one battery is fully charged, the controller automatically diverts power to the other.

Key features include a 5-year warranty with an estimated 15-year life, negative common ground compatibility, and epoxy encapsulation for protection against dust and humidity. Its four-stage PWM pulse charging extends battery life, while specific settings, like slow-switching charging mode, help avoid interference with sensitive loads. The controller is easy to install with factory presets, fully automatic operation, and fault recovery. It also reduces costs by charging two batteries without requiring separate solar systems. For single-battery setups, the unit automatically adjusts to deliver 100% of the charge and allows a second battery to be added later.

Morningstar remote LCD meter RM-1:

The remote LCD display/meter provides comprehensive system monitoring by displaying various charging parameters, including solar panel current, battery voltages, amp-hours, temperature, logged data, settings, alarms, and error reports. Built-in LED lights also indicate battery level and operating state. Please note that available functions depend on the connected controller or inverter; for full details, refer to the user manual in the 'Documents' tab. The large numerical display and backlit menu, combined with easy-to-use buttons, make system navigation and monitoring straightforward.

This meter connects to a compatible Morningstar controller or inverter via a 10m RJ-11 cable and can be mounted directly onto a surface using the provided holes or flush-mounted by removing the frame. Designed for efficiency, it features an extremely low self-consumption of just 6mA with the backlight off and 15mA when the backlight is on, minimizing power loss.

Additional items:

This kit includes a waterproof double cable entry gland which is perfect for getting cables from outside to inside and keeping the place fully waterproof. The kit also includes 2 x 5m 6mm² dual core battery cable with a 20A fuse, fuse holder and 8mm ring terminals, a pair of T-MC4 connectors and a pair of 5m 6mm² solar extension cables.
