Newest 20A Solar Charge Controller with LCD Display
Introduction:
CARSPA company 's newest PWM solar charge controller, it is a state-of-the art device which was developed according to the latest available technical standards.
Main Features and Functions:
Pulse Width Modulation Technology which offers the good efficiency of your PV system.
1. Automatically detects 12/24V system voltage.
2. A big LCD screen display one main window and 7 different sub windows: battery voltage, PV charge current, Load discharge current, total PV charge Ah, total PV discharge Ah, the setting of constant voltage charging, the setting of low voltage disconnect, the setting of low voltage reconnect
3. The constant voltage charge, low voltage disconnect and reconnect data settable by user.
4. External temperature sensor
5. Temperature-compensated, three-stage I-U curve charge regulation
6. Full electronic protection (reverse polarity, over-current, short-circuit, over temperature, current drawback, lightning, etc.)
7. Highest efficiency
8. Positive ground
9. Dual terminals for solar panel input
10. Battery type can be: GEL, AGM and solar battery etc.
