Pre-organised switching and cabling for compatible X-ESS systems.
The SolaX Matebox is an accessory designed for compatible X-ESS G4 installations. It groups pre-routed internal connections to simplify a professional battery-storage installation and reduce complex field wiring.

The Matebox is not a battery or inverter on its own.
Its purpose is to support a compatible SolaX system by organising connections and switching. Model selection is tied to the inverter generation, phase arrangement and system architecture.
X1 Matebox
For specified compatible single-phase X-ESS arrangements.
X3 Matebox variants
Basic and Advanced versions serve specific compatible three-phase configurations.
Installation planning
The wall area, module stack, cable entries, isolators and access must be laid out before equipment is fixed.
Useful when it is part of the correct SolaX package.
- New compatible X-ESS G4 installations
- Projects prioritising an organised equipment layout
- Single-phase or three-phase systems using the matching unit
- Installations with planned battery and backup connections
Mr Solar design check
- Exact inverter and Matebox compatibility
- Single-phase versus three-phase supply
- Required switching and protected circuits
- Space, wall construction and module clearances
- Current installation guide and wiring schematic
Matebox versions are not interchangeable. The exact part must be specified from the current SolaX documentation for the inverter and system design.
The Matebox adds no battery capacity.
It organises switching and connections within a compatible SolaX system. Runtime comes from the attached battery; output comes from the inverter and EPS design.
Illustrative examples
- A 10 kWh battery is not changed into a larger battery by adding a Matebox
- The Matebox cannot increase the inverter’s kW output
- Backup duration depends on the connected battery and protected loads
- The correct Matebox version helps implement the designed system safely
