Key capabilities
Core functions provided by each eqGrid unit and by coordinated deployments.
Phase balancing
Improved feeder symmetry and reduced imbalance.
Operational continuity
Hybrid on-grid/off-grid operation for critical distribution environments.
Topology flexibility
TN, IT and split-phase compatibility through configurable transformer topology.
Distributed architecture
Multi-node coordination and resilient edge deployment with separated downstream load segments per eqGrid unit.
Utility integration
SCADA, fieldbus and edge messaging support through established protocols.
Electrical characteristics
Grid and load interface ratings for localized resilient edge operation.
The system supports up to 80 A three-phase TN grid and load interfaces, while localized stabilization and transient balancing are supported through an integrated low-voltage battery subsystem.

Important deployment constraint
When multiple eqGrid units are connected to the same upstream supply, the downstream loads must be electrically separated per eqGrid unit. Multiple eqGrid units must not operate in parallel on a common downstream load bus unless this has been specifically engineered and approved for the installation.
This requirement ensures predictable voltage stabilization, phase balancing and protection coordination for each local grid segment.

Distributed resilient edge architecture
Multiple eqGrid systems can be coordinated across feeders and operationally critical distribution segments to improve resilience, voltage quality and localized continuity. When units share the same upstream supply, each unit requires a separate downstream load segment.
