xMPPT WireBox-L MC4 for 150/70 and 250/70 VE.Can Solar Charge Controllers
The MPPT WireBox-L MC4 is a protective wiring enclosure designed for Victron SmartSolar and BlueSolar MPPT charge controllers in the 150/70 and 250/70 VE.Can range. It covers the electrical connections on the underside of the controller, providing a tidy and protected termination point for MC4 solar input cables. Suited to professional installations where cable management and connection protection are required.
Key Features
- Compatible with Victron MPPT 150/70 and 250/70 VE.Can charge controllers.
- MC4 connector version, designed for direct connection of MC4-terminated PV cables without additional adapters.
- Encloses and protects the battery, load and solar wiring terminals on the underside of the controller.
- Reduces the risk of accidental contact with live terminals after installation.
- Lightweight construction at 0.23 kg, adding minimal bulk to the installed unit.
- Sold as a single WireBox unit, sized specifically for the large (L) MPPT controller format.
Product Overview
Victron MPPT charge controllers leave their wiring terminals exposed by default. In a professional installation, particularly in enclosures, caravans, marine applications or any environment where personnel may access the equipment, covering those terminals is good practice. The WireBox-L MC4 clips onto the base of the compatible controller and encloses the connection area, keeping cables routed neatly and terminals shielded from accidental contact.
The MC4 variant is specific to installations using MC4 solar connectors directly into the PV input. This avoids the need for ferrules or bare-wire terminations at the PV input side, which is common in installations where the PV string cable runs directly from the array. Ensure you select the correct WireBox variant for your controller model and cable type before ordering, as the MC4 and standard versions are not interchangeable.

Installation Notes
The WireBox-L MC4 should be fitted after all wiring connections to the charge controller have been completed and verified. Always ensure the system is de-energised before making or adjusting any connections. Installation of MPPT charge controllers and associated wiring should be carried out by a qualified electrician or competent person familiar with DC solar systems. For grid-connected systems, ensure compliance with G98 or G99 requirements as applicable.
