Choosing Between eWay and eWay Lite: Which Wireway Solution Is Right for Your Project?

Blog, Solar Batteries

When designing a solar-plus-storage system, every detail matters — from battery selection to inverter integration to the wireway that ties it all together. Fortress Power’s eWay and eWay Lite are both engineered to deliver clean, streamlined, and safe connections for the Envy inverter family, but each solution serves a distinct purpose in the field.

Before comparing features, here’s the most important compatibility distinction to understand:

Compatibility Overview: eBoost vs eForce
  • eWay Lite is a simplified wireway built exclusively for the eBoost 16 kWh battery, making it ideal for single-stack residential systems where clean design, fast installs, and cost-efficiency are the priority.
  • eWay, the full wireway solution, is designed for both the eBoost and the larger eForce systems (with a different configuration for eForce than eBoost), making it the right choice for multi-battery, whole-home, off-grid, and commercial-leaning projects that demand greater scalability and advanced controls.

Quick takeaway: Choose eWay Lite for streamlined eBoost installs. Choose eWay when you need scalability, space-saving benefits with a vertical form factor, and advanced features.

Front Features: Power Handling & Guardian Integration
  • eWay: Built with a three-terminal 750A busbar, it enables multi-battery paralleling and includes a DIN-rail bracket for optional Guardian Gateway mounting. This gives installers more flexibility for advanced monitoring and system control.
  • eWay Lite: Features a single 250A battery terminal and no DIN-rail bracket, making it a leaner option for one battery.

Installer takeaway: For multi-battery builds with Guardian, choose eWay. For simple, single-battery projects, eWay Lite keeps it clean and cost-effective.

Back Design: Connectivity & Indicators
  • eWay: Includes rear knockouts, a status indicator, and a Guardian Wi-Fi antenna port for enhanced visibility and connectivity.
  • eWay Lite: Offers a minimalist rear layout — no knockouts, no antenna port, and no indicator.

Installer takeaway: If visual system feedback and Wi-Fi integration matter, eWay provides more built-ins. If your design doesn’t require extras, Lite keeps things minimal.

Top Mounting Options
  • eWay: Designed with a removable top cover, allowing installers to mount an Envy inverter (21kW/12kW/10kW/8kW) directly on top, saving wall space and consolidating equipment.
  • eWay Lite: Intended for side-mount configurations, making it the perfect match when pairing a single Envy inverter to a single eBoost battery.

Installer takeaway: Choose eWay when you want stacking flexibility. Choose Lite when the layout calls for a clean, straightforward side-mount.

Side Functionality: Shutdown & Safety
  • eWay: Includes a power switch + integrated Rapid Shutdown (RSD) switch for battery, PV, and AC output.
  • eWay Lite: Includes the power switch only, without integrated RSD. However, you still have the option of having PV disconnection when initiating RSD through the Envy inverter.

Installer takeaway: Projects requiring NEC compliance with full rapid shutdown should use eWay.

Cost Savings
  • eWay Lite can reduce material cost by up to $150 for single-inverter installs and up to $300 in parallel applications.

Installer takeaway: If budget matters and the system doesn’t need Guardian or RSD features, Lite delivers savings without sacrificing reliability.

  • Guardian mounting & Wi-Fi integration
  • On-board status indicators & rapid shutdown
  • Stacked inverter mounting and maximum system flexibility

Choose eWay Lite if your project needs:

  • A cost-effective wireway exclusively for eBoost
  • A clean side-mount configuration
  • A simplified solution without extra wiring, indicators, or RSD controls

Both wireway solutions are built with installer-friendly architecture, durable construction, and clean system design. Whether your focus is scalability or simplicity, the eWay family ensures a tidy, professional finish & smoother installation from start to finish.
