The Challenge

Storage Economics Live and Die on Round-Trip Efficiency

Every percent of conversion loss is energy you paid to store and cannot sell. Storage projects also face tight grid-code, safety and scalability requirements.

Round-trip losses: Charge and discharge through conventional PCS stages costs 4–8% of stored energy
Grid-code barriers: Frequency response, reactive support and fast response are increasingly required
MV integration: Utility-scale BESS must step up to 10–35 kV cleanly and reliably
Battery safety: Cell-level monitoring, thermal management and fail-safe control are non-negotiable
Scalability: Projects grow from MWh pilots to GWh pipelines — the architecture must scale

Our Solution

SiC PCS + MV SST: Storage That Earns More Per Cycle

Higher conversion efficiency, tighter grid support and an integration path from container to substation — built on our SiC power electronics platform.

SiC PCS Efficiency

SiC-based PCS raises conversion efficiency to ≥98.5% — visibly better round-trip economics over the project life.

Bidirectional by Nature

Four-quadrant operation for charge, discharge, reactive support and black-start capability.

Grid Support

Frequency regulation, voltage support and fast response built in — qualifying the system for ancillary-service revenue.

MV Integration

Container-to-35 kV paths via SST or step-up solutions — clean, efficient and protection-coordinated.

BMS & EMS, Full Stack

Battery management to cell level, plus cloud EMS for dispatch, optimization and O&M analytics.

Scalable Containers

Standardized liquid-cooled cabinets and containers scale from 100 kWh pilots to GWh pipelines.

FAQ

Common Questions

How much does SiC PCS actually improve round-trip efficiency?

Moving from IGBT to SiC-based PCS typically adds 1–2 percentage points of one-way conversion efficiency. Over a 10-year, daily-cycle project, that is a material share of the revenue — our proposal includes an energy-economics model so you can see it for your duty cycle.

Do you supply just the PCS, or the whole system?

Both. We supply PCS, BMS and EMS as building blocks for system integrators, and we deliver complete containerized BESS or SST-integrated systems for EPC-style projects.

What safety and testing comes with a system?

Every system ships with factory test reports, battery safety documentation and commissioning support, designed against IEC 62619 / IEC 62933 and the applicable local codes.
