The main function of a regulator or controller is to keep your leisure batteries fully charged by regulating the flow of electricity to the battery without allowing overcharging of the battery. They also prevent leisure battery current flowing back from the battery to connected items at night. Without overcharge protection the life expectancy of batteries are reduced. Solar Charge Controllers vary in type from simple controllers to more sophisticated controllers that utilize pulse width modulation (PWM) or maximum power point tracking (MPPT) to assure the battery is being and kept fully charged. These more sophisticated controllers use special monitoring software, to control charging by monitoring in real time the state of charge.
Solar charge controllers or regulators are recommend to avoid battery damage from overcharging or deep discharge. The Steca range of regulators are designed for simplicity of installation and can be used with GEL, AGM (absorbed glass matt), sealed and non-sealed lead acid batteries. They should be protected from the weather and located within as near as possible to the battery bank. We will be offering the 100% waterproof Steca range of charge controllers in eary 2008 for any customers using solar solutions based on rivers, or waterways ccnp training. All models featured below include a Low Voltage Disconnect (LVD) facility, to ensure batteries do not get over-discharged.
