Energy storage inverter PQstorI

One stop solution for energy storage

PQstorI is the new generation of Hitachi Energy's energy storage inverters. PQstorI is designed to efficiently address the needs of the fast growing energy storage market for behind the meter applications such as peak shaving, back-up power, power quality, as well as utility scale applications such as load leveling, frequency response, capacity firming and integration of renewables.

PQstorI offers many benefits like flexibility, modularity and higher efficiency for energy storage applications that need world class 3-level bi-directional inverters.

PQstorI's flexibility to operate with any third party controller and multiple mounting options make it an obvious choice for the system integrators and consumers looking for energy storage solutions.

The operation of PQstorI is highly user-friendly. Advanced communication features allow the devices to be operated and controlled via cloud-connected user platforms with real-time access of data. User can communicate through Modbus or Wi-Fi through a PC or smartphone.
