  • Parallel connection for power expansion up to 6 units (1.8kVA) without fan
    •  DIASINE® GR300 series can be connected in parallel up to 6 units and the output power can be expanded to 1.8kVA without fan.

  • Synchronous control by AC output terminal
    • DENRYO’s original synchronous control technology (patented) enables GR300 work in parallel only have to connect AC output. This technology makes installation and operation become easier, because there is no need exclusive parallel control boards or complex synchronization signal setting like conventional products.

  • N+1 redundancy
    • Because of the N+1 redundancy, GR300 makes the system expanded easier at any time. The function can also prevent the system stopping if a single unit failure. This contributes to improved system stability and reliability.

  • The smallest sine wave DC-AC power inverter in the world
    • DIASINE® has achieved the lightest weight of 0.9kg and the smallest volume of 1.5L in the same output class of inverters. The height of DIASINE® is 44mm/ 1.7 inch (1U). The lightweight and small features reduce the system weight and size.

  • Input reverse polarity connection protection by built-in circuit
    •  Existing inverters will be damaged if the input battery is connected in reverse. DIASINE® has the exclusively own built-in circuit of input reverse polarity protection. This circuit protects DIASINE® not to get damaged even if the battery is connected with reverse polarity. Moreover, the reverse polarity warning LED of DIASINE® lights immediately to inform the user the reverse polarity connection.

  • Operating silently based on fanless structure
    • The efficient heat design achieved the fanless structure. The fanless structure leads silently operation without the fan-generated noise.

  • Wide input voltage range
    • The input voltage range of DIASINE® is wider than other inverters in the same class. Therefore, batteries with wide range variation of voltage, such as lithium-ion batteries, can be used. It is also possible to charge battery while the DIASINE® is operating.

  • Wide range of operating temperature
    • DIASINE® operates under a wide range of temperature from -20 to 60°C.
    *DIASINE® GR300 will not stop the output automatically. Under the environment with temperature exceeding 30°C, please use the load along refer to the derating curve of each model.

  • Pure sine wave output and high efficiency
    •  The output waveform is as same as the sine wave of commercial power supply, of which the total harmonic distortion is less than 3%. High-efficiency circuit and switching control achieve over 88% efficiency at rated load. It contributes to the stability of the system during operation without extra wasted energy consumption.

  • Switchable output voltage and frequency
    • The output voltage 100/110/115/120 Vac, and frequency 50/60 Hz easily switch by buttons. DIASINE® adapts to areas with different voltage, frequency, and various electric appliances.
