Grid Tied Solar Inverter HIVERTER - NP201i Series
HIGHLIGHTS The Hitachi Solar Inverter is a Grid Tied (GT) Solar Inverter with reactive power control and high efficiency, which is the heart of the Solar Power Generating System. It converts DC power generated by the Photovoltaic (Solar) Array to AC power that is fed to the Utility Power Grid System. The Hitachi Solar Inverter is fully compatible with thin film and / or crystalline PV modules. With proper maintenance and parts replacement on schedule it has an operating life upto 25 years. As a part of Hitachi Group Company, Hitachi Hi-Rel Power Electronics Pvt. Ltd (HHPE) is manufacturing Grid Tied Solar Inverters in India based on the contemporary technology of Hitachi Ltd, Japan. It brings reliable products supported by very high quality standards, manufacturing processes and work culture. Assured long term technical and spares support.

CONTROL FUNCTIONS
TECHNICAL SPECIFICATIONS (KW SCALE)
Start / Stop Function (Emergency Switch) a. Inverter START / STOP Switch or Contact Input Signal (Start and stop of the Inverter is carried out by START / STOP switches). b. Control position can be selected by DIRECT / REMOTE Switch. Direct Control Direct control of the Inverter is possible by using START / STOP Switches. Remote Control Remote control of the Inverter can be done by contact input signals (START / STOP Switches) or communication. Fault Ride Through (FRT) – Low Voltage Ride Through (LVRT) Against sudden changes of amplitude or phase of AC Voltage, Inverter high-speed detection and control capability can prevent AC over current.
PV Input Controlled Stand-by Function a. When the DC input power or voltage reduces due to decrease in solar irradiation or any other causes, the Inverter goes into stand-by mode with its inverter switching functions turned off automatically. In this case, the DC switchgear will be closed.
Monitoring(Indicators) Inverter Status measurement data, Fault data, Historical records and other information is displayed on the LCD screen.
