Application of an equalizing charge to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery’s service life (with the exception of GEL and lithium batteries).
  4. With temperature compensation employed, charging parameters can be automatically adjusted (with the exception of lithium batteries).
  5. A wide range of load working modes facilitate the product’s application to different types of street lights and monitoring devices.
  6. The product provides overcharge, over-discharge, overload protection, as well as short-circuit and reverse-connection protection.
  7. By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.
  8. A range of parameter settings and power-down saving functions are available, thus requiring no repeated setting.
  9. The product provides a dot matrix graphic LCD screen and a human-machine interface with 2 keys.
  10. The user-friendly design of browser and dynamic interfaces ensures convenient and intuitive operations.
  11. (An optional communication function) provides a RJ12 data port (output of TTL232 level or Bluetooth signals), with the data adopting the standard Modbus protocol, and can be used together with our upper computer monitoring software or mobile phone APP.
  12. Boasting an industrial-grade design, the product can function well in various tough conditions. 13.TVS lighting protection is adopted.

Five Load Working Modes

  1. Pure light control (0): When sunlight disappears and the light intensity drops to the starting point (light control off), the controller initiates a 10-minute delay (settable) to confirm the starting signal, and then switches on the load for operation. When sunlight emerges and the light intensity reaches the starting point, the controller initiates a 1-minute (fixed) delay to confirm the shutting-down signal and then shuts down
    the output to stop the load’s operation.
  2. Light control + time control (1 to 14): The starting process is the same as pure light control. After operating for a preset period of time (settable from 1 to 14 hours), the load stops operation automatically.
  3. Manual mode (15): In this mode, the user can switch the load on or off by the keys, no matter whether it’s day or night.
  4. Debugging mode (16): When the solar panel voltage is higher than the “light control off” voltage, switch off the load immediately; when the solar panel voltage is lower than the “light control on” voltage, switch on the load immediately.
  5. Normal on (17): The energized load keeps in output state.

  2. When the system is saving data, the screen may shake slightly. This is normal and the user may ignore it. 6.
    Safety Advice
    1) When connected to a 24 V or 48V system, the solar panel terminal voltage may exceed the limit for human safety. If operation is to be performed, be sure to use insulation tools and keep your hands dry.
    2) If the battery is reversely connected, the controller itself won’t be damaged, but the load end will have a negative voltage output, which may damage your load device. Take care not to let thishappen.
    3)In the 48V system, separate reverse connect battery or separate reverse connection of solar panel controller will not damage; but if in reverse connection of the battery and is connected solar panels, or solar panels on the reverse connection is connected to the battery may cause damage to the controller.
    4)The battery contains a large amount of energy. Therefore, in no cases should the battery be short circuited. It’s recommended that a fuse be serially connected to the battery.
    5)Keep the battery away from fire sparks, as the battery may produce flammable gas.
    6) Keep children away from the battery and controller.
    7) Follow the safety advice provided by the battery manufacturer.

3) After parameters have been set, long press HP Smart Solar Charge Controller User Manual  & troubleshooting 34 for 2 s to save and exit.
parameters shall be set according to the following rule: over-discharge voltage <ovover-discharge return voltage <=under-voltage warning <floating charging voltage <boost chcharging return <=equalizing charging voltage <overcharge voltage; and two adjacent values shall hahave a difference greater than 0.5 V.

Charging and Discharging Overload Protection and Recovery Time

In the charging and discharging overload protection mechanism, the relation between overload current and protection time is as follows: An overload current 1.25 times of the rated current initiates a delay of 30s before starting protection; similarly, 1.5 times, 5s and 2 times, 1s. Overload recovery: automatic recovery after 1 minute.

Load Short Circuit and Recovery

Short-circuit automatic recovery time: 1st time, 5 s; 2nd time, 10 s; 3rd time, 15 s; 4th time, 20 s; 5th time, 4 hours or automatic recovery the next day; or long press HP Smart Solar Charge Controller User Manual  & troubleshooting 35 to make the load resume output.

Installation Instructions and Precautions

  1. The controller shall be installed securely, and its dimensions are as follows:
  2. Installation hole diameter: 3.2 (mm)
    HP2430/2440 External dimensions: 164.0×103.5×47.0 (mm) Installation dimensions: 154×85 (mm)
    HP2450/2460 External dimensions: 189.27×127.2×54.0 (mm) Installation dimensions: 180×92.2 (mm)
    HP4830/4840 External dimensions: 189.27×127.2×54.0 (mm) Installation dimensions: 180×92.2 (mm)
    HP Smart Solar Charge Controller User Manual  & troubleshooting 37
  3. Precautions:
    1. If it is 12V system, the bottom left corner of LCD display will show ’12V’, 24V system will show’ 24V’,36V system will show ’36V’, 48v system will show ’48V’.
    2. The first step is to connect the battery. If the connection is made correctly, the controller screen will light up; otherwise, check whether the connection is correct.
    3. The second step is to connect the solar panel. If sunlight is present and strong enough (the solar panel voltage is greater than battery voltage), the sun icon on the LCD screen is on; otherwise, check whether the connection is correct (it’s recommended that the operation be performed under the debugging mode).
    4. The third step is to connect the load. Connect the load leads to the controller’s load output terminal, and the current shall not exceed the controller’s rated current.
    5. As the controller will generate heat during operation, it’s recommended that the controller be installed in an environment with good ventilation conditions.
    6. Choose cables with large enough capacity for connection, in case too much loss incurred on the lines causes the controller to misjudge.
    7. The controller has a common positive pole inside. If grounding is needed, ground the positive pole.
    8. It’s important to fully charge the battery regularly. At least once full charging every month is recommended, and f to do that may cause permanent damage to the battery. Only when in-flow energy outpaces out-flow energy can the battery be charged fully. Users shall bear this in mind when configuring the system.
    9. Check whether the controller’s each connection terminal is tightened securely; if not, it may suffer damage whe current passes .
