Product Description
PWM Solar Charge Controller
PWM series(12V\24V Auto 20A\30A\40A\50A\60A\80A)
Description
The solar charge controller is one of key components of PV off-grid solar power system. Our PWM solar charge controller can be adopted to different charge methods based on different types of batteries and environment. With large LCD screen, buttons and USB output ports. Double solar sources inputs making it much more reliable.
Features
1. Impulse Width modulation technology, which offers the good efficiency of your off-grid solar power system.
2. Automatically detect 12/24VDC or 24/48VDC input voltage.
3.With a large LCD screen display one main window and seven different sub windows: Battery voltage, PV charge current, Load discharge current, Total PV charge Ah, Total PV discharge AH, Sets of constant voltage charging, Sets of low voltage reconnect.
4. The constant voltage charge, low voltage disconnected and reconnect data are settable by users.
5. External temperature sensor
6.Full electronic protections (Reverse polarity, Over current, short circuit, Over temperature, Current drawback, Lightning etc.)
7. High efficiency
8. Positive grounded
9. Dual terminals for solar panel inputs
10. Battery types can be: GEL, AGM and solar batteries etc.
