Seven Supporting Categories | Three Scenario Solutions | Mass Deployment with Leading Manufacturers

AI computing centers, PV-storage-charging microgrids, high-voltage ultra-fast charging, rail transit, and more: SST solid-state transformers are becoming the key hub of the new-generation power system. Stepping 10kV down to 800V DC, high-frequency SiC power devices, and bidirectional energy flow give SST disruptive efficiency gains, but they also introduce an entirely new set of safety challenges.

Who handles insulation safety? How is partial discharge prevented? How are AC and DC branches metered? How do multiple SST units coordinate with one another?

A complete supporting ecosystem now fully covers all seven of these categories.

Seven Supporting Categories at a Glance

PART 01

DC Insulation Monitoring

Core SST safety component. Essential for 800V DC IT systems.

The SST high-voltage DC bus is ungrounded. A single-point insulation drop can easily lead to a short circuit and fire. Dedicated insulation monitoring instrumentation protects the 800V DC bus:

AIM-D100-TS

DC 100 to 1000V wide measurement range, suited for the 800V SST output bus and high-voltage DC cabinets in computing centers. Provides real-time insulation resistance monitoring and tiered ground-fault alarms.

AIM-D100-TL

A low-voltage DC variant, suited for the energy storage side and battery-cluster coupled SST branches, providing all-round insulation protection.

PART 02

Partial Discharge Monitoring

Early warning for insulation aging in SST high-frequency SiC modules and transformers.

SST's high-frequency, high-voltage operating conditions are prone to partial discharge, making early prediction of device breakdown risk essential:

APD300-L (Wired PD Monitoring)

Suited for medium-voltage 10kV input-side SST units and high-frequency transformer cavities, precisely capturing partial discharge signals.

APD300-W (Wireless Ultrasonic PD)

For modular cabinet-type SST and outdoor fast-charging SST cabinets, offering wiring-free installation. Supports discharge-magnitude mapping, trend analysis, and over-threshold remote alarms, suited for SST topologies above 30kHz.

PART 03

Bidirectional AC/DC Metering

Gateway and branch energy metering, efficiency analysis, carbon accounting.

High-Voltage DC Metering (SST DC output 800V bus, bidirectional storage charge and discharge)

DJSF1352-RN

0 to 1500V wide-range DC meter, class 0.5S bidirectional metering, compatible with Hall-effect transducers. A standard fit for computing-center and storage SST.

AMC100-ZD

DIN-rail precision DC acquisition module, for internal SST cabinet branches and power-unit branch monitoring.

AC-Side Metering (10kV incoming line, PV/grid gateway)

APM521

Embedded multifunction power meter for medium-voltage cabinet SST incoming lines, monitoring harmonics, THD, and voltage sags.

DTSD1352

DIN-rail bidirectional AC meter for PV-storage SST grid connection with anti-backflow metering.

ADW300 Series

Split-core CT wireless IoT meter for outdoor cabinet-type SST retrofits, supporting outage-free installation.

PART 04

Relay Protection and Rapid Fault Isolation

SST medium-voltage input, bus short circuits, reverse-flow protection.

AM5SE-T

A 10kV medium-voltage microprocessor-based protection device for the SST high-voltage incoming line, providing overcurrent, instantaneous trip, zero-sequence, and overvoltage protection.

AM5SE-IS

Dedicated anti-islanding protection for bidirectional PV-storage SST grid connection, disconnecting rapidly on grid voltage loss to prevent reverse power feed.

ARB6 Arc-Flash Protection

For SST power cabinets and bus compartments, provides millisecond-level cutoff of arc faults, preventing cabinet explosion.

APView400

Online power quality monitoring that addresses SST high-frequency harmonics and voltage flicker, helping meet grid-connection standards.

PART 05

Temperature Sensing and Fire Monitoring

SiC power modules, liquid cooling, busbar temperature-rise protection.

ARTM-8 Multi-Channel Temperature Module

PT100-based, collects temperature data from SST internal power devices, the high-frequency transformer, and busbar copper, with over-temperature linked shutdown.

AMB100 Small Busbar Monitor

Monitors temperature rise and leakage current in AI data-center SST downstream 800V DC small-busbar plug-in enclosures.

PART 06

Edge Gateway and Coordination Controller

Multi-SST coordination, data forwarding, strategy control.

ACCU-100L Microgrid Coordination Controller

Coordinates multiple SST units in parallel operation and source-grid-load-storage interaction, executing valley-charge and peak-discharge, peak shaving, and power-allocation strategies.

ANet Edge Computing Gateway

Supports 4G and Ethernet connectivity, aggregating insulation, PD, metering, and temperature data. Uses Modbus and MQTT protocols to connect SST unit controllers to the cloud platform.

Acrel-2000ES Energy Storage Management System

Dedicated to storage-coupled SST scenarios, interfacing with BMS, PCS, and EMS platforms.

PART 07

AcrelEMS3.0 Energy Management Cloud Platform

The upper-level operations and maintenance brain of the SST system.

All SST monitoring data is unified in the cloud, enabling centralized management from a single platform:

Overall SST energy consumption statistics, efficiency analysis, and automatic carbon-emission accounting
Unified alarms for insulation, PD, and temperature faults, with mobile app push notifications
Remote operations and maintenance for multi-site SST clusters, historical curve traceability, and report export
Adapted for standardized O&M across computing centers, energy storage stations, and high-speed fast-charging stations
