Highlight Features

  • 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.
  • 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.
  • Optimum MPPT tracking efficiency of up to 99.9%.
  • Advanced digital power supply technologies raise the circuit’s energy conversion efficiency up to 98%.
  • Supports Gel, Sealed, Flooded batteries and 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.
  • With LCD screen to check device operating status and also modify controller parameters.
  • Built-in over-temperature protection avoid damaged by overheat.
  • Temperature compensation automatically adjust charging and discharging parameters in order to extend the battery life.
  • TVS lighting protection.
