Auto12/24V 10A PWM Solar Charge Controller (QWP-1410SLC)
Features of 20A Solar Charge Controller:
1. Microcontroller digital accuracy.
2. PWM charge mode.
3. State of charge (SOC).
4. Temperature compensation.
5. Automatic detection of the voltage.
6. Short circuit protection.
7. Reverse polarity protection.
8. Reverse current protection at night.
9. Over charging or discharging protection.
10. Over-load protection
1, The controller adopts German design thought, that is "one point, and is double close-loop(voltage and current double control), can make maximum energy of solar cell charge up to battery, which will enchange the efficency.
2, The display part adopts LED or LCD mode, Which can carry on real time monitoring and display to battery voltage, load current, charge current, daily generates/discharges electricity, the month generates/discharges totally, Load short-circuit value, environment
3, The controller is of a series of voice, light warning and protection function including over charge, over discharge, over load, short circuit, reverse connection over voltage, over heat or first shutdown, second shutdown and so on.
4, Supply normal connection of RS232/RS485.
5, Diversified class arrester can be installed according to the different requirements.
6, Temperature compensation.
7, Light control, diesel generator, standby power supply can be provided when needed.
