Auto-adjustable voltage 12v 24v 48v 60A PWM solar power charger automatic controller
NOVA Solar Charge Controller is a photovoltaic (PV) charge controller that tracks the PV array to deliver the available current for charging batteries. When charging, the Controller regulates battery voltage and output current based on the amount of energy available from the PV array and state-of charge of the battery. NOVA Solar Charge Controller can be used with 12V/24V/48VDC battery systems, Max PV input 50V or 100VDC .
Features
1. Automatic Identification System Voltage, 12V/24V or 48V auto recognition.
2. Humanized LCD displaying and double button operation of man-machine interface.
3. Completed technical data for setup and modify.
4. High efficiency intelligent PWM 3stage charging
5. The load control mode can be selected, the timer function can be reset for street light at night.
6. Discharge capacity control
7. RS485 communication interface (optional)
8. Discharge Counter of Ampere Hour
9. Working Storage Function: record the total run time of system, record timers of error during running time, record times of full charged battery.
10. Reliable over voltage protection,short circuit protection,overload protection,overcharge protection, over-discharge protection.
11. Accurate temperature compensation, correcting the charging and discharging voltage automatically, improving the battery lifetime.
12. Roundly reverse connected protection.
13. Solar Panels, Battery, Solar Charge Controller positive poles are all connected together, adopting negative MOSFET in series control circuit.
