  • Brand: Temank
  • Product Model: ML4830N15
  • Type: Solar Charge And Discharge Controller
  • With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.
  • A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.
  • A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
  • The product boasts an optimum MPPT tracking efficiency of up to 99.9%.
  • Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%.
  • Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc.
  • The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
  • Instantaneous large current startup of capacitive loads is supported.
  • Automatic recognition of battery voltage is supported.
  • LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults.
  • Historical data storage function is available, and data can be stored for up to a year.
  • The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.
  • The controller supports standard Modbus protocol, fulfilling the communication needs of various occasions.
  • The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat.
  • Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery's service life.
  • The controller also features a battery over-temperature protection function, and when the external battery temperature exceeds the set value, charging and discharging will be shut off so as to protect components from being damaged by overheat.
  • TVS lighting protection

Battery Type Default Parameters

The User battery is customized battery. The system’s default voltage parameters are consistent with sealed lead-acid battery parameters. When modifying battery charging and discharging parameters, observe the following logic:

  • Overvoltage Disconnect Voltage>Charging Limit Voltage≥ Equalizing Voltage≥ Boost Voltage≥ Floating Charging Voltage>Boost Restoring Voltage;
  • Overvoltage Disconnect Voltage>Overvoltage Disconnect Restoring Voltage;
  • Low Voltage Disconnect Restoring Voltage>Low Voltage Disconnect Voltage≥ Discharging Limit Voltage;
  • Under-Voltage Alarming Restoring Voltage>Under-Voltage Alarming Voltage≥ Discharging Limit Voltage;
  • Boost Restoring Voltage>Low Voltage Disconnect Restoring Voltage

 Note: Custom (User) battery type using lithium battery method:

  1. fixed system voltage (not automatic identification).
  2. equalizing charge interval, balancing charging time and temperature compensation are all set to 0. At this time, the controller has lithium battery control and lithium battery activation function.
  3. choose "lithium battery" or "custom battery type lithium battery": after battery feeding, second days can activate battery from solar panel.
