Frequently Asked Questions
What is integrated into a BESS container?

The battery energy storage system (BESS) container uses a modular design that fully integrates LiFePO4 batteries, a Battery Management System (BMS), a Power Conversion System (PCS), an Energy Management System (EMS), and an automatic transfer switch into a single standard container structure.

What are the battery specifications of the system?

The system relies on lithium iron phosphate cells (LFP 48173170E) rated at 120Ah and 3.2V. These cells are built into standard modules of 24 cells (2P12S, 9.216kWh), which are then configured in clusters of 18 modules (2P216S, 165.888kWh) with operating voltage ranges between 604.8V and 766.8V.

What operation modes does the energy storage container support?

It supports three main operational modes: Grid discharge mode (380V), Isolated network operation mode (380V with standalone voltage control), and Grid-connected charging mode (400V) with automated frequency tracking.

Is the solar inverter expandable or customizable?

Yes. The hybrid storage inverter supports configuration flexibility by enabling parallel units, programmable work parameters, remote control capability for diesel generators (DG), and features an interactive LCD touchscreen.

What is the noise level during operations?

The entire BESS system container runs quietly during daily operations, keeping acoustic noise emissions below 70 decibels (dB).
