New application Hitachi VFD, for AC motor (fan , pumps ..etc ) using Solar Cell Power Supply directly.
The application in general depends on converting the power of the sun rays to a DC power using Solar Cells , Our Hitachi’s VFD Inverters use these power to drive the fan , pump or any AC motor ;
Directly or with storage batteries,
The mechanism of this process goes by the following explanation:
if the operator needs to operate the AC motor (fan , pumps ..etc) in the day hours
, it can use Hitachi VFD inverter direct with the solar cell which Supplies about 530 – 650 volt DC and it will work as long as the sun is shining
Inverter and Motor Information:
The Inverter: Capacity 22 Kw
The Capacity Motor: 18.5 Kw.
The Voltage coming from the Solar Cell unstable: 577 vDc.
The output current: 32.1 A
The total Solar cell capacity: 24000 Watt
The Distance from the Solar cell to the Inverter: 30 M
The Distance from the Inverter to the Pump Motor: 10 M
The time operating in the day: from 7 Am to 6 Pm
If the operator needs to operate the AC motor (fan , pumps ..etc ) wither on day time or at nights he just has to use the storage batteries and the Hitachi VFD inverter connecting to the batteries(its output voltage abut 530 -650 DC).
