Product Introduction
A solar lamp controller, also known as a solar charge and discharge controller, is a vital component in a solar photovoltaic system. It serves to coordinate the solar panels, batteries and loads of the system, ensuring a safe and efficient operation. The function of the controller cannot be overstated, as it plays a critical role in the overall performance of the photovoltaic system. By effectively managing the charging and discharging of the batteries, the solar lamp controller maximizes the use of renewable energy and provides a sustainable power source for various applications.
If you're looking for a solar lamp controller that can handle LED lighting and dimming functions, this combined charge controller and constant current driver is perfect. It's specifically designed for use with solar-powered LEDs, and it offers advanced features like Maximum Power Point Tracking charging. This means that it can optimize the charge and discharge management of your solar system, resulting in greater flexibility and reduced costs. With this controller, you can rest assured that your solar lighting system will perform at its best.

To ensure activation, it is required to check the battery voltage regularly, specifically when it falls below 12.1/24.2 V. This should be done at least every 30 days. The purpose of this check is to ensure that the battery maintains sufficient power for proper functioning. Neglecting to comply with this requirement may lead to a compromised performance. Therefore, it is highly recommended to prioritize this task to maintain the optimal operational capacity of the battery. | |
