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

SAFETY INSTRUCTIONS 1. Make sure your battery has enough voltage for the controller to recognize the battery type before first installation. 2. The battery cable should be as short as possible to minimize loss. 3. The regulator is only suitable for lead acid batteries: OPEN AGM GEL. it is not suited for nickel metal hydride lithium ions or other batteries. 4. The charge regulator is only suitable for regulating solar modules.Never connect another charging source to the charge regulator. PRODUCT FEATURES 1. Build-in industrial micros controller. 2. Large-screen LCD display charging and discharging current display cumulative power generation and discharge power query temperature display light control+delay control; adjustable charge and discharge parameters with power-off memory and other functions. 3. Dual USB output the maximum current of 2.5A to support Apple s mobile phone charging. 4. Fully 3-stage charge management. 5. Build-in short-circuit protection open-circuit protection reverse protection over-load protection. 6. Reverse current protection low heat production. SYSTEM CONNECTION 1. Connect the battery to the charge regulator-plus and minus. 2. Connect the photovoltaic module to the regulator-plus and minus. 3. Connect the consumer to the charge regulator-plus and minus. The reverse order applies when deinstaling! An improper sequences order can damage the controller!
