Hitachi Hi-Rel Power Electronics Pvt. Ltd.

The Hitachi Solar Inverters is a Grid Tied (GT) Solar Inverters 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 Inverters 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 is manufacturing Grid Connected 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 NP201i, Hitachi Solar Inverters Series are among the best available On Grid Solar Inverters that are suitable for Multi-Megawatt Solar Power Plants. It is also known as Solar PCS (Solar Power Conditioning System), Solar PV Inverter (Solar Photovoltaic Inverter). 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.
