Solar Inverters
HIVERTER - NP201i Series
The Hitachi Solar Inverter is a 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 up to 25
years.
HIVERTER NP 201i, Hitachi Solar Inverter Series is among
the best available GT Solar Inverters that is 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. Large touch screen display
collects the real-time data and provides fault detection
diagnostics to ensure faster retrieval of information for
corrective action.
As a part of Hitachi Group Company, Hitachi Hi-Rel Power
Electronics Pvt. Ltd is manufacturing 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 with assured long term technical and spares
support.

Solar Inverters
HIVERTER - NP201i Series
Control Functions
Start / Stop Function (Emergency Switch)
a. Inverter START / STOP switch or contact input signal
(Start and stop of the Inverters is carried out by START / STOP
switches).
b. Control position can be selected by DIRECT / REMOTE switch.
Direct Control
Direct control of the Inverters is possible by using
START / STOP switches.
Remote Control
Remote control of the Inverters can be done by contact input
signals (START / STOP Switches) or communication.
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 Inverters goes into standby mode with its inverters switching functions turned off
automatically. In this case, the DC switchgear will be closed.
Fault Ride Through (FRT) – Low Voltage Ride Through (LVRT)
Against sudden changes of amplitude or phase of AC Voltage,
Inverters high-speed detection and control capability can prevent
AC over current.
Output Power Limiting Function
When the Hitachi inverters output exceeds its maximum value, the
input power drawn will be adjusted to prevent the Inverters from
being overloaded.
b. Upon recovery of the DC input the Inverters switching operation
will be restored automatically.
With the feature, the Inverters can keep operating even under
momentary voltage dip of 60% for up to 0.5 seconds.
Maximum Power Point Tracking (MPPT) Control
Inverter has a function to maximize power generation at a given
amount of solar radiation by adjusting DC voltage.
Monitoring (Indicators)
Inverter status measurement data, fault data, historical records and
other information is displayed on the LCD screen.
Status: Inverters Status l Switchgear Status l Grid Status
Measurement
AC Output : Voltage l Current l Power l Power Factor l Frequency
DC Input :
Voltage l Current l Power
Fault Data : Inverters Failure l Grid Faults
Historical Records

Reactive Power Control
3 primary types of control methods
¡
¡
¡
¡
Auto-tuning of power factor based on grid conditions
Fixed power factor (can be set to unity)
Fixed amount of reactive power
Can be based on a pre-set value or based on adjustable
settings
Ease of Installation and Commissioning
Low weight and compact footprint saves time and resources at site
DC Input Panel
Protection is provided for individual DC input with optional current
monitoring feature.
AC Output Panel
AC Output panel with ACB and extended terminals for connecting
the cable up to 500 SQMM AL.
