  • Alternator exceeds 92% efficiency
  • Generator smart startup according to the battery voltage, battery capacity , remote start signal and electric supply fault condition
  • Ensure to make engine longer lifetime, it will switch to the battery for power supply when generator's load is over low.
  • Smart management for battery's load
  • Free maintenance for non-bearings  Alternator lifelong
  • Regularly switch the operation between two generators in turns easily without adding any other spare parts
  • Achieve multi-generators to parallel synchronous operation without adding any other spare parts easily


Advantages of DC genset over AC genset

  • Low Fuel Consumption: NdFeB Magnets Alternator for high efficiency. Under low load, the voltage regulator can vary the engine speed resulting in fuel savings of up to 30%.
  • Expansion capacity: DC generators can be connected in parallel for load sharing (whereas AC generators cannot) which allows for capacity expansion.
  • Compatibility: Some AC generators and switch mode power supplies are not compatible. Because of the current pulsing load of switch mode power supplies, some AC genset voltage regulators may not be able to regulate the voltage. DC gensets will have no such problem.
  • Low EMI emissions: Alternator has no bearings, couplings, brushes, slip rings, or rotating fields. There are no alternator parts to wear.
  • Low Noise Level: Improving alternator efficiency reduces the demand on the engine and hence the engine noise. Noise is further reduced by eliminating the brushes, slip rings and the alternator fan.
  • Intelligent management of battery charging: Automatic three-step charging circuit consists of bulk rate, overcharge, and float. Battery life is extended.
  • Automatic Temperature Compensation: The genset output can be temperature compensated for superior battery charging. A temperature sensor is placed on the battery and the regulator responds by adjusting the output voltage.
  • Comprehensive system protection: The system is protected from over voltage, battery reverse connection, short circuit and low engine oil. Avoiding faults leads to stable performance.
  • Dynamic LCD display: Parameters are dynamically displayed for the charge condition and charge process. Touch button operation for convenient use.
