Technical FAQs 4

What is a solar grid substation?

Solar Grid Substation - outdoor switching stations to connect a full solar park to the grid, manufactured in sheet metal housing consist of medium voltage switchgear (gas insulated - GIS or air insulated - AIS type) per client’s requirements fully equipped with all protection relays, measurements, monitoring and control systems.

What is a polinovel 2mwh commercial energy storage system?

Max. Efficiency Get your Exclusive Offer! Polinovel 2MWH commercial energy storage system (ESS) is tailored for high-capacity power storage, ideal for large-scale renewable energy generation, PV self-consumption, off-grid applications, peak shaving, and emergency backup power.

What is a containerized mobile substation?

Containerized mobile substations are sheltered and address applications in challenging environmental conditions including areas of high pollution, and humidity. Customers requiring shorter overall delivery times and minimal on-site work have been the main drivers for Hitachi Energy's development of pre-fabricated indoor substations.

What is a small distribution substation?

Smaller distribution substations are subdivided into container-sized modules, which can be manufactured, assembled and tested at the factory, allowing easy transport and fast installation and commissioning at site.
