Product Description
As per noted name, we manufacture, export and supply Dc/Ac Inverters. The offered inverters are manufactured using utmost quality components and sophisticated techniques under the stern guidance of our adroit professionals. These inverters are suitable to regulate the input fluctuations in various kinds of electrically operated machinery or instruments. Available in several technical specifications, the provided Dc/Ac Inverters can be purchased from us at competitive prices within the promised time span.
The newest Double Start Mode low frequency off grid inverter features:
- Two types of start mode: Step Down Voltage Start and Variable Frequency Start.
- The output frequency can be set.
- The output voltage can be set between -40 % to +20 % of rated voltage.
- The DC input voltage range can be set. Over-voltage point, under-voltage point, over-voltage recovery point , under-voltage recovery point all can be set via the LCD panel.
- The under-voltage recovery time can be set.
- Pure sine wave output.
- Powerful data display and fault instruction function.The LCD can display DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, Generated amount KWH, time and date, temperature, fault code display.
- Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, with high efficiency and stable performance. It also with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It's service life can up to 15 years or more.
- Wide input voltage can be set from 100-500v, 200-850v, off grid inverter can work without batteries.
- With Low Frequency Transformer, which ensures that inverter has high efficiency and low no- load loss.
- Could add AC bypass input: Battery power priority or Main power priority
- Passed the European CE (EMC and LVD) certificated and accredited by Australia CEC energy network.
