Double USB Port 12V/24V 10A PWM Solar Charge Controller (QWP-1410USBE)
Features:
1. Identify 12V/24V system voltage automatically.
2. Manual control for the load.
3. LED indicates the working status of battery and load.
4. Double USB output charging for various electronic products. Max load current reach up to 1.2A.
5. Adopting advanced ternary form charging algorithm, equalizing charge for battery once a week to prevent battery from imbalance and vulcanization effectively so that the battery service life will be extended.
6. External temperature sensor can realize high-precision temperature compensation
7. Various protections: Over charging protection, over discharging protection, over load, short circuit protection, reverse polarity protection, TVS lightning protection.
Electronic Protections:
· PV array short circuit
· Over discharging
· Over charging
· Load overload
· Load short circuit
· PV reverse polarity
· Battery reverse polarity
Installation and wiring
1.12V or 24V voltage worked, the storage battery connected first, controller will work after recognize the battery volt automatically.
2. Connecting the solar panel: If connection is right, indicator of solar panel will twinkle. If no, please check the connection.
Connecting the load: Connect the load wire to the controller's load output terminal. Ensure the load current no exceed rate current.
Suggestions for use
1. When the battery over discharged, please cut off the USB load. Otherwise the USB only supply the emergency charging and it is bad for the battery.
2. Controller will fever during working. Therefore, it is suggested to install it in a ventilated environment.
3. Temperature compensation function needs to test the ambient temperature. Therefore, please place the storage battery and the controller in the same environment.
4. Choosing the cable with enough capacities for connection to avoid excessive loss on circuit which may cause the controller wrong judgment.
5. Common anode designed. If grounding, please use the anode.
