50kW – 200kWh

P50 is the smallest of the E22’s P-family series. This electrical 50kW energy storage system is an electro-chemical all vanadium product with four (4) hours of energy storage ready to discharge at rated power. It comes fully packed in an standard 20’ container and includes for Remote Diagnostic and Continuous Monitoring of all parameters, including the State of Charge (SOC).
This tiny unit is prepared to perfectly integrate with all kind of renewable power sources in a vast variety of applications such isolated microgrids, grid-connected buildings, and also utility-scale solar and wind facilities, delivering most of the production-correction benefits these industries require: energy shifting; peak load matching; demand reduction, etc.

250kW – 1,000kWh

Is a more versatile option. This electrical energy storage system is also an electro-chemical all vanadium product which can accommodate various number of hours of energy storage. The system is built around a modular building block of 250 to 330kw of power that allows the parallel connection of several modules, allowing at that time to configure a modular energy system.
The units come also full containerized and include for Remote Diagnostic and Continuous Monitoring of all parameters, including the State of Charge (SOC).
E22 offers several options for the delivery of this P250 units such as a Turn Key package for the whole installation or a more Flexible Delivery where customer brings to the project certain elements like a building, civil works, etc.


EMS system control for energy storage by E22


E22’s Battery Management System (BMS) has been designed to manage E22’s VRFBs systems. This control system has the flexibility to maximize the battery performance, adapting the Auxiliary Power consumption to the minimum level to maximize the Battery System Efficiency. Also, E22’s BMS can adequate the E22’s VRFBs electrochemical behavior to any energy and power application.

One distinctive feature of the E22’s BMS is the ability to analyze and diagnose the  component’s State of Health and immediately send an internal info to LEMS and EMS to activate a preventive maintenance. This type of alarm info so generated by the BMS prevents that the identified event raises to an Emergency Stop System event.

This state-of-the-art control system comes along fully integrated with the E22’s VRFBs systems and it’s not commercialized separately.


E22’s Local Energy Management System (LEMS) has been engineered to manage properly the coordination between the BMS and Power Control System (PCS). This coordination optimize the round trip efficiency (AC/AC efficiency) operating both system properly, considering the electrical conditions of the POC and the Control Setpoints from the EMS.

E22’s LEMS also guarantees the PCS strategies at the Point of Connection (POC) and is prepared to provide customers a flexible and limited Control SCADA platform to monitoring and reporting the state of the entire energy storage system (PCS and BMS).
