Battery Energy Storage Systems Testing & Simulation including BESSTI (Battery Energy Storage System Testing Instrument)

The Battery Energy Storage System Tester Instrument (BESSTI) is specifically designed for testing of commercial Energy Storage System (ESS). BESSTI can be utilized in the laboratory environment and/or in the field to facilitate Factory Acceptance Test (FAT), Site Acceptance Test (SAT) and commissioning of BESS. The portable test device can interface and exchange commands with BESS through analog signals or communicate with the BESS controller using MODBUS, DNP3 or other standard protocols. The embedded power quality meters also provide direct measurement of actual power values (P, Q, V and I) at the terminal of the BESS. The built-in power/energy tracking capabilities and performance assessment tool allows the user to compare the generated set-points and expected power output of a BESS with the measured outputs, for any pre-specified control strategy. The tester can be used for testing and evaluation of ESS controls and communication systems, or can act as a site controller or a Battery Management System (BMS) for new application tests. 










BESSTI can be utilized in the laboratory environment and/or in the field to facilitate:

                               - Factory Acceptance Test (FAT)

                               - Site Acceptance Test (SAT)

                               - Commissioning Test and Performance Evaluation
