Stormentum Power Conversion System

The Stormentum Power Conversion System, based on Modular Multi-level Conversion (MMC) technology, is built from the ground up to address modern residential energy needs for the next decade.

  • 50% lower hardware cost than microinverter or optimizer-based systems
  • Battery-agnostic: supports high- and low-voltage storage without lock-in
  • Streamlined installs with standard tools and familiar workflows
  • Modular, distributed design enables optimal performance and flexible system scaling

High-efficiency, low-cost electronics are the building blocks that deliver the power a home needs.

  • Modular 400 W DC and AC power processor — multiple Cells combine to scale system power
  • Creates storage-only or solar+storage systems
  • Module-level MPPT and rapid shutdown with solar
  • 50% fewer components than a microinverter
  • Uses standard PV wire and MC4 connectors — no proprietary cabling

Core

A centralized hub for AC and DC connections, supporting direct integration with your choice of battery storage.

  • Central hub for AC and DC connections - not an inverter
  • Supports 11.5 kVA of cells @ 120/240 Vac
  • Manages storage integration and grid interconnection
  • Integrates with load controllers, meter collars, VPP and energy management platforms
  • Compact wall-mounted form factor with multiple conduit entry points

Unified Software

Designed to simplify installation, streamline commissioning, and optimize system operation.

  • Unified mobile and browser-based interface for installation and system control
  • Automated commissioning workflow with step-by-step verification
  • Commissioning and system setup with or without an Internet connection
  • Real-time system performance monitoring and diagnostics
  • Dynamic operating modes with real-time control of solar, storage and home loads
  • Role-base access for installers, operators and homeowners

Integrations & Grid Services
