PWM solar charge controllers provide a cost-effective method of regulating charging between solar panels and compatible batteries. They are widely used in smaller off-grid solar systems, basic lighting systems, agricultural applications, RVs and simple backup installations where system requirements do not require advanced MPPT functionality. Models can be supplied with different rated currents, system voltages and battery charging profiles. Some versions include LCD displays, USB outputs and basic protection functions. GraceRay can source PWM controllers in different configurations for distributors and system integrators looking for economical solar charging components.
