PR3030 Solar Charge Controller with LCD Display


30 Amp Solar charge controller/regulator. Made in China by Fangpusun

30 Amp Solar charge controller: PR3030 with graphic display and datalogging features.

Automatic recognition of battery voltage (12 V / 24 V) 

CE and ROHS certificates 
2 year warranty


Buttons A simple scroll up/down button allows you to view the display and data logging functions.


On/Off button controlls all loads up to 30 Amps connected to controller. LVD (Low Voltage Disconnect will operate for battery protection).


LCD Display windows

Window 1. (Default SOC) The State Of Charge (SOC) is represented visually in the form of a fuel guage and percentage display.

Displays the charge level, day/night level and consumer on/off.  Instead of SOC value, flashing battery voltage is displayed during low voltage warning and control.



Window 2. Battery Voltage  Displays the battery voltage measured by the regulator PR3030-30-amp-charge-controller
Window 3. Module output:  Displays real time solar module`s current output PR3030-solar-chqarge-controller
Window 4. Charging Current:  Displays the charging current flowing into battery from solar module. If battery is low this begins as full module output and then tapers off as battery becomes full and charge meets more resistance. PR3030-solar-charge-controller-30A-with-LCD-display
Window 5. Load Draw:  Displays the current drawn from battery by appliances connected to the load output PR3030-30-amp-solar-charge-controller-with-LCD-display-and-data-logger
Window 6. Ah+in Battery Charging Meter:   Displays the cumulative sum of recharged Ah since installation or reset PR3030-solar-charge-controller-with-LCD-display
Window 7. Ah-out Battery Discharging Meter:  Displays the cumulative sum of Ah drawn by load from the battery since installation or reset PR3030-solar-charge-controller-with-LCD-display-and-data-logger
Warning Window. Deep Discharge Protection:  As an early warning the SOC bar or voltage value flashes.  The face still looks friendly. PR3030-solar-PV-charge-controller-with-LCD-display-made-in-china-by-fengpusun-2-year-warranty
Warning Window. Load Disconnection:  If the deep discharge protection has been activated, the SOC bar or the voltage value flashes and the face looks sad until reconnection point has been reached fangpusun-PR3030-solar-pv-charge-controller-with-LCD-display
