Quick Details

  • Maximum Current: 30A
  • Rated Voltage: 12V
  • Application: Charger Controller
  • Brand Name: LDSOLAR
  • Charging Mode: PWM
  • Model Number: SD2430C
  • Max PV input voltage: 50V


the following example is for you reference.

this series Product base on in series PWM mode, with full digital technology and LCD Display, auto run mode with large application range, such as off-grid solar Home system, traffic indicator, solar street lights, solar garden lights and so On. the intelligent charging process has been optimized for long battery life and improved system performance.

Main Advantages:


V     Short Circuit and Reverse Connected  Protection (Solar Panel)

When the solar panels have short Circuit or reverse connection, the controller will be off the charging Immediately, after clearing of the short circuit, the charging will be Automatically continue.

V     Reverse Connection of Battery Protection

If the batter reverse connection, the Controller will not destroy, corrected the connection the controller will be Normally working.

V     Battery over Voltage Protection

When the voltage of Battery was more than 16.5V, the controller will be auto closed charging and Output in order to destroy the battery and loads.

V     Battery Low Voltage Protection (LVD)

When the voltage of battery was reach to LVD (Low Voltage Disconnection) point, the controller will be auto closed the output in order to over-discharge the battery.

V     Overload Protection

If the current of load is more than 1.5times rated current of controller, the controller will be cut off the output after 30s and lock. Users have to decrease loads and press" "Unlock, or 30s later the controller will auto restart unlock.

V     Short Circuit Protection

When the load have short circuit, the Controller will be cut off immediately and lock. Users have to clearing the Short circuit and press" "Unlock, or 30s later the controller Will auto restart unlock.

V     Lightning Protection

this product could only protect small Lightning induction, we suggest to use lightning rod at frequency area.
