PWM
The Macroon Power Plus off-grid system, featuring a PWM (Pulse Width Modulation) charge controller and battery storage, provides a cost-effective solution for managing solar power in off-grid environments. The PWM controller works by gradually reducing the amount of power supplied to the batteries as they approach full charge, preventing overcharging and prolonging battery life. While less efficient than MPPT controllers in varying sunlight conditions, PWM controllers are reliable and simpler, making them a solid choice for smaller systems with consistent sunlight and lower power demands.
