ETFE has a memory effect or self-healing capacity in the event the panel comes into contact with branches etc thus ensuring any slight abrasions are ?healed? within a few hours. The flexi range can even be walked on with soft deck shoes During production the ETFE is dimpled to further protect the panel and provide an anti-slip surface particularly useful if the panel is fitted to a boat deck. Completely waterproof Each panel is assembled to ensure complete encapsulation. This ensures the six layer heavy duty laminate protects the solar cell circuit from extreme conditions. The junction box is also injected with special silicon guaranteeing no water ingress. Cells protected from hot spots Where used on a camper van or boat partial shading of a solar panel is typical. In these circumstances heat build-up and damaging hot spots can occur leading to a significantly reduced life cycle of the panel. The larger 60w and above PV Logic flexi panels have up to two shading diodes housed within the fully waterproof junction box to prevent this occurrence. Superior design There are no square edges on a PV Logic flexi solar panel Rounded panel corners and a unique curved junction box provide superior adhesion no snag lamination and no sharp edges. The junction box is mechanically fixed in addition to being bonded to the panel. Strain relief is provided for the fitted 4m UV stabilised PV cable ensuring it cannot be accidentally pulled from the junction box. Includes 10A Dual Battery Charge Controller This controller is for off-grid solar systems and has the additional functionality that it can charge two batteries simultaneously and can work on both 12v or 24v systems. The charging process has been optimised for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults. Reverse current protection. Unique dual battery charging function. Efficient Series PWM charging increases battery lifetime and improves solar system performance. 12/24V automatic recognition.
