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.

HIVERTER NP 201i, Hitachi Solar Series are

among the best available GT Solar Inverters that are

suitable for Multi-Megawatt Solar Power Plants. The

transformer-less design and 3-level PWM technology

improves the efficiency of the system to 98.7%. The

Inverter has a compact design and lower weight for ease of

installation, repair and maintenance. The large touch

screen display collects real-time data and provides fault

detection diagnostics to ensure faster retrieval of

information for corrective action.

Output Power Limiting FunctionWhen the Hitachi inverter output exceeds its maximum value, the input power drawn will be adjusted to prevent the inverter from being overloaded.

PV Input Controlled Stand-by Functiona. 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.

b. Upon recovery of the DC input the Inverter switching operation will be restored automatically.

has a function to maximize power generation at a given

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.

With the feature, the Inverter can keep operating even under momentary voltage dip of 60% for up to 0.5 seconds.

Start / Stop Function (Emergency Switch) a. 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.
