OEM *Solar Technology STCC20 20A solar charge controller

Solar Technology Dual Battery Charge Controller This controller is for off-grid solar systems and has the additional functionality that it can charge two batteries simultaneouslyand can work on both 12v or 24v systems. The charging process has been optimized 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. Overload protection Open circuit protection Lightning surge protection Charge current protection up to 20A (RS 905-4536) Note All solar panels (except the 5w and 10W) require a voltage regulator to ensure that the battery is not overcharged. We recommend (STCC20) controller for solar systems with a total watts of 100w to 300w Solar Panels and Chargers Solar “photovoltaic” panels use the power of the sun to generate electricity and can be used in a variety of applications from calculators to homes. They are most effective, versatile and cost saving in many commercial and leisure applications for charging 12/24V batteries. Solar panels provide power through batteries at off grid and isolated locations and are widely used in critical telecommunications and telemetry applications. Solar panels enable rapid installation of equipment at remote sites, either temporary or permanent, avoiding the costs and inconvenience of grid connection. They are designed for very low maintenance and longevity. How Much power? The daily power production of a solar panel can be calculated by multiplying the panel’s peak power rating by between 0.5 and 6 depending on the time of year, angle and location. For example; an 80Watt solar panel produces a peak current of 4.55A. Solar Installation Solar panels are usually installed at a 55-65° angle for optimal wintertime performance. For a year round power supply solar panels can be combined with Wind chargers. Solar panels can be connected in parallel to increase power and in series to increase voltage. To complete the system deep cycle batteries, a voltage regulator and electrical cables are required to get up and running. A range of convenient mounting kits are available for pole or wall mounting.
