10A/20A/30A 12V/24V Auto Solar Charge Controller Dual USB Solar Panel Regulator

NOTE: 1. This controller is suitable for 3 types of batteries, including lead-acidbatteries(12V/24V auto) lithium-ion batteries(3 strings of 111V lithiumbatteries); lithium iron phosphate batteries(4 strings of 128V) Dontused in Other battery.Battery type descriptionB1 is a lead-acid battery(12V/24V auto)B2 is a lithium ion battery (3 strings of 111V lithium batteries);B3 is lithium iron phosphate battery(4 strings 128V) 2.The battery cable should be as short as possible to minimize loss.3. When installation for the first time, set the battery type according tothe type of battery and make sure that the battery has enough voltageso that the controller can recognize the correct battery type.4. The charge regulator is only suitable for regulating solar modules.Never connect another charging source to the charge regulator. Features: 1. Build-in industrial micro controller 2.
