Solar Kit Contents 30 Watt Polycrystalline Solar Panel with 5M cable attached 2 Metre battery connection cable with crocodile clips PWM Solar Charge Controller including USB output l In the event that the solar panel is in shade for a prolonged period, our solar panels either have one or two built-in bypass diodes which will enable the panel to continue generating. Solar Panel Battery Charge Regulator Controller 12V / 24V Auto Switching Solar charge controllers are required to regulate the power output from the solar panels to ensure effective charge of a typical 12V or 24V lead acid battery without overload. PWM (Pulse Wave Modulation) solar charge controller provide a cost effective solar charger for the solar panel outputs in our range. Optimised charge control which helps to prolong the life of the battery. 3-6% more effective than non-PWM charge controllers. LED indicator light to show battery state. Uses industrial grade micro-controller chip to work in a wide range of
