Feature: 1. Work as an intelligent, multi-purpose solar charge and discharge controller, CMB series LCD controller's each parameter can be flexibly set to meet your different application needs. 2. Equipped with PV-Power technology, the solar panel or the battery can be started at either end. 3. When the battery is seriously under-voltage, the solar panel can also try to charge and the product can be used directly as a charger. 4. Solar controller supports12V 24V lead-acid battery, 11.1V 22.2V ternary lithium battery and 12.8V 25.6V lithium iron phosphate battery. 5. For battery power failure activation function, battery controller can be set to open the load during the day and close the load at night.
