Its ETFE top layer offers a unique "memory effect" or self-healing capacity, allowing minor abrasions from branches or light impacts to recover within hours. The dimpled ETFE surface also provides an anti-slip finish, making it safe to walk on with soft deck shoes, particularly useful for boat installations. Each panel is assembled with a six-layer heavy-duty laminate, ensuring complete encapsulation and protection of the solar cell circuit from extreme weather. The junction box is injected with special silicone to guarantee no water ingress, and its unique curved design with rounded panel corners prevents snagging and provides superior adhesion. Strain relief is also provided for the fitted 4m UV stabilised PV cable. Charging & Battery Management (STCC10) The included 10A Dual Battery Charge Controller (STCC10) is designed for off-grid solar systems, offering the unique ability to charge two separate battery banks simultaneously. It features automatic 12V/24V system voltage recognition, simplifying setup and ensuring compatibility with various battery configurations. Utilising efficient Series PWM charging, the controller optimises the charging process for extended battery life and improved overall system performance. Its comprehensive self-diagnostics and electronic protection functions safeguard against common installation mistakes and system faults, providing peace of mind for users. Typical Applications Application Description Campervans & Motorhomes Providing auxiliary power for leisure batteries, lighting, and onboard appliances. Marine Vessels Charging service batteries on yachts, boats, and narrowboats, even on slightly curved decks. Off-Grid Cabins & Sheds Supplying power for lighting, small electronics, and communication systems in remote locations. Remote Monitoring Powering sensors, cameras, or telecommunication equipment in isolated or hard-to-reach areas. Built-In Protection Functions The included 10A Dual Battery Charge Controller (STCC10) incorporates multiple electronic protection features to ensure system safety and longevity: ▶ Reverse Current Protection • Overload Protection • Open Circuit Protection • Lightning Surge Protection • Deep Discharge Protection • Charge Current Protection up to 10A. Common Questions What makes this solar panel "flexible"? This is a semi-flexible solar panel, designed to conform to slight curves, typically up to 3cm per metre. This makes it ideal for mounting on non-flat surfaces common on campervans, motorhomes, and boat decks. Can I walk on the PV Logic Flexi panel? Yes, the durable ETFE top layer is designed to be walked on with soft deck shoes. Its dimpled texture also provides an anti-slip surface, enhancing safety when installed on a boat deck or vehicle roof. How does the dual battery charge controller work? The STCC10 controller intelligently manages the charging of two separate battery banks (e.g., leisure and starter batteries). It prioritises the main battery while ensuring the secondary battery also receives a charge, all while automatically recognising 12V or 24V systems. Is this kit suitable for 24V systems? Yes, the included 10A charge controller automatically recognises and adapts to both 12V and 24V nominal system voltages, making it versatile for various battery setups. Installation Notes The flexible panel can be bonded to flat or slightly curved surfaces (up to 3cm curve per metre) using a suitable adhesive such as Simson ISR 70-03, which is included in the fixing kit. Alternatively, the panel features pre-drilled 4.5mm holes for mechanical fixing, either instead of or in addition to bonding. It is crucial to follow the recommended glue pattern (detailed in the instructions) to ensure adequate airflow underneath the panel, preventing heat build-up and potential warping under extreme heat. All electrical connections should be made securely and in accordance with relevant safety standards. If unsure, consult a qualified professional. Before You Buy Verify the available surface area for panel installation matches the panel dimensions (806 x 665 x 4mm) to ensure a proper fit. Confirm your battery system voltage (12V or 24V) is compatible with the included charge controller's automatic recognition feature. Consider your estimated daily power consumption to ensure the 80W output is sufficient for your specific energy needs. Ensure you have any additional tools or materials required for your chosen installation method, beyond the bonding agent and cable gland supplied. Specifications are subject to change by the manufacturer. Always verify compatibility and installation requirements before purchase. E&OE.
