What essential function does the charge controller perform in an off-grid system?
Answer
It manages electricity flow from the solar array to the battery bank, preventing overcharging
The charge controller is described as an essential device within the complete ecosystem required for a reliable off-grid system. Its critical role involves managing the flow of electricity originating from the solar array into the battery bank. Specifically, it ensures that the batteries are not subjected to overcharging conditions. Overcharging is detrimental because it severely degrades the lifespan and capacity of the battery chemistry, whether lead-acid or lithium-ion, thereby protecting the investment in the energy storage component.
