Product Introduction
Solar lamp controller is used in solar photovoltaic system, it is also called solar charge and discharge controller. The controller is a very important part of the photovoltaic system, which plays the role of coordinating solar panels, batteries and loads. Its application enables the entire solar photovoltaic system to operate efficiently and safely.
Combining charge controller and LED constant current driver, this solar lamp controller is ideal for solar LEDs, especially when dimming function is required. The advanced Maximum Power Point Tracking charging method enables the most thorough optimization of system charge and discharge management, which not only increases system flexibility, but also reduces system costs.
