Features Equipped with PV power technology, the solar panel or battery can be started at both ends. As an intelligent multi-purpose solar charge and discharge controller, each parameter of the CMB series LCD controller can be flexibly adjusted to meet your different application requirements. For the activation function of the battery power failure, the battery controller can be set to open the load during the day and close the load at night. The solar controller supports 12V 24V lead-acid batteries, 11.1V 22.2V ternary lithium batteries and 12.8V 25.6V lithium iron phosphate batteries. In case of strong undervoltage of the battery, the solar panel can also try to charge and the product can be used directly as a charger.
