PWM30LCD RENOGY 30A Pulse Width Modulation Solar Charge Controller with LCD Manual 2775 E. Philadelphia St., Ontario CA, 91761 1-800-330-8678...
1. Product Information The PWM30LCD is an intelligent and multifunctional solar charge controller. The customized LCD display makes it easy to operate. All the controlling parameters can be adjusted to the user’s needs. This controller has the following features: Visual LCD with graphic symbols ...
2. Installation We suggest you choose the appropriate cables to ensure the current density < 4 A/mm . This is good for reducing voltage drop between the solar array and the charge controller. Recommendation: For 30 Amps, use a 10mm cable.
3. Operation 3.1. Explanation of LCD Graphic Symbols Icon Description Icon Description Load output is OFF Battery is not receiving charge Load output is ON Charging battery at full speed Supplying current to loads Controller is at normal operation Load connected Controller is at abnormal operation Solar array connected...
3.3. Parameter Review and Setting Once the charge controller is powered up, it will display the battery voltage. This screen is the main interface of the controller. Press to go through the all of the charge controller’s screens. Screens with parameters that are adjustable e.g. “Low Voltage Protection”...
3.3.4 Solar Input Current This screen will display the total amperage being produced by the solar panel(s). This number will decrease when approaching float- charging mode. 3.3.5 Load Current When the load is ON and a device is connected to its terminals, the screen will show the amount of current is drawing from the battery.
3.3.8 Ceasing Charging Voltage The picture on the right shows the screen with the maximum allowed battery voltage. When the battery voltage reaches up to this voltage, the controller will disconnect the charging state to prevent the battery from overcharging. After the battery voltage drops,...
3.3.11 Load Work Mode In this screen, the load output behavior is as follows: 24h – Indicates normal mode. Loads are under the condition of supplying power without interruption. 1h-23h – Indicates timed light control. Load terminals start to supply power after sundown amount hours...
4. Protection Features and Troubleshooting 4.1 Low Voltage Protection When the battery voltage is below than the protection voltage, the controller will enter in low voltage protection state, which disconnects the load output. Use the solar panels or alternate charger to charge the battery. When battery voltage recovers above the specified voltage on the “Recovering Voltage”...
4.4 Solar Panels Not Detected When is flickering, means that the controller does not detect the input PV array. Check for loose connections and also check that the cables are in good condition. If the panel still not detected, make sure that the polarity is not reversed.
6. Technical Specifications 6.1. Electrical Characteristics Description Parameter Rated Working Voltage 12V/24V Rated Charge Current Rated Load Current Maximum Input Power 360W (12V), 720W (24V) ≤48V Solar Input Voltage Battery Type Sealed AGM (Lead Acid) and Flooded Float Charging Voltage (adjustable) 13.8V/27.6V Low Voltage Protection (adjustable) 10.7V/21.4V...
