Energy storage inverter PQstorI

One stop solution for energy storage and power quality

PQstorI is the new generation of ABB’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. Loaded with enhanced power quality features like harmonics filtering, reactive power compensation and load balancing, makes it an ideal power converter for energy storage application.

Its wide range of power ratings, coupled with the flexibility to operate with any third party controller and multiple mounting options makes it an obvious choice for the system integrators and consumers looking for power storage solutions.

The operation of PQstorI is highly user-friendly, thanks to its 7-inch color touchscreen named as PQoptiM controller. ABB Ability enabled communication allows 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.
