6 Amp Solar Power Center

The SPC2 is a solar power center, it can be used to handle all of the power functions for small 12 Volt solar powered devices. It contains a photovoltaic charge controller and a low voltage load disconnect circuit. The low voltage disconnect has a load on-off switch, and a battery low voltage indicator. By using the SPC2 as the center of a solar powered device, long battery life is assured. The SPC2 is primarily designed to be a solar lighting controller, it can be used to power radios and other high capacitance loads with a minor switch and circuit modification (shown in dotted lines on the schematic).

The SPC2 solar power center is engineered to optimize the functionality and longevity of small 12 Volt solar-powered devices. At the core of its design is a photovoltaic charge controller, which regulates the voltage and current coming from the solar panels to ensure that the batteries are charged efficiently without overcharging. This charge controller is crucial for maintaining battery health, as it prevents damage that can occur from excessive voltage levels.

In addition to the charge controller, the SPC2 incorporates a low voltage load disconnect circuit. This feature is essential for protecting the battery from deep discharge, which can significantly reduce its lifespan. The low voltage disconnect monitors the battery voltage and automatically disconnects the load when the voltage drops below a predefined threshold, ensuring that the battery retains enough charge for recharging and future use.

The SPC2 also includes a load on-off switch that allows users to manually control the power to connected devices, providing flexibility in operation. Accompanying this switch is a battery low voltage indicator, which serves as a visual signal to inform users when the battery voltage is critically low, prompting necessary action to prevent battery damage.

While the SPC2 is primarily designed as a solar lighting controller, its versatility allows for adaptation to other applications, such as powering radios and high capacitance loads. This adaptability may require minor modifications to the circuit, as indicated in the schematic with dotted lines. Such modifications can enhance the performance of the SPC2 in various applications while still ensuring that the fundamental protective and operational features remain intact.

The overall design of the SPC2 emphasizes efficiency and reliability, making it an ideal choice for small-scale solar power applications. By centralizing power management functions, the SPC2 not only simplifies the integration of solar technology into everyday devices but also promotes sustainable energy usage through its effective management of battery life and load control.The SPC2 is a solar power center, it can be used to handle all of the power functions for small 12 Volt solar powered devices.
