Frequently Asked Questions

How does DC coupling optimize large-scale renewable energy systems?

DC coupling allows captured solar energy to be stored directly with minimal conversion losses. This ensures a greater portion of power is available for on-site use or grid dispatch, enhancing overall sustainability and ROI.

What role does the Power Conversion System (PCS) play in the container?

The PCS acts as a high-power, bidirectional inverter. it converts DC from solar panels and batteries into AC for use, replacing the need for separate inverters and streamlining the entire infrastructure.

Why is DC coupling more efficient for energy storage projects?

It avoids multiple DC-AC-DC conversion steps. Since solar energy can directly charge the batteries in DC form, energy losses are significantly reduced compared to AC-coupled systems.

What are the main benefits of on/off-grid large-scale storage?

Key benefits include a simplified system layout, fewer components, reduced balance of system (BOS) costs, and seamless integration for both grid-tied and remote off-grid applications.

What safety measures are integrated into the ESS container?

The containers feature separated electrical and battery compartments to prevent thermal runaway spread, integrated HVAC for thermal management, and HFC-based fire suppression systems.

Can the capacity of the storage system be customized?

Yes, the system is highly modular. We offer standard 20FT and 40FT containers, but the total energy capacity can be customized from kWh up to GWh scales based on client requirements.
