1 Solar Inverters HIVERTER - NP201i Series

2 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. 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. 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.

4 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. 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. 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 Operation Record l Grid Trouble Record l Fault Record 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. b. Upon recovery of the DC input the Inverters switching operation will be restored automatically. 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. 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. Inverter PV Power Station 1 MW, 2 MW & 2.5 MW Hitachi PV Power Station is an advanced containerised solution for large-scale and commercial PV (Photovoltaic) power plants, which contains Solar Inverters and optional equipments for auxiliaries, serves to protect electric equipments from environmental influence. Standard & robust design Easy connectivity to MV station IP53 protection class mechanism design Easy to transport Easy to install Highly Optimized Energy Conversion 04
