Victron MPPT WireBox-XL Tr 150-85/100 & 250-85/100 VE.Can | SCC950400210

The MPPT WireBox-XL Tr is a protective enclosure that fits over the DC wiring terminals of Victron SmartSolar and BlueSolar MPPT Tr charge controllers. It is built for the transformer-based 150-85, 150-100, 250-85 and 250-100 VE.Can range and helps installations meet enclosure and safety requirements by covering exposed terminals once cables are connected.

• Covers all DC input and output wiring terminals on the charge controller
• Sized specifically for the XL Tr form factor for a secure fit
• Reduces the risk of accidental contact with live DC terminals after installation
• Weighs 0.23 kg, adding minimal bulk
• Supports tidy cable management in panel rooms, battery rooms and enclosures

Product overview

Victron MPPT Tr controllers in the 150 and 250 VE.Can series carry high DC currents at the battery terminals. Left exposed after wiring, those terminals present a contact risk and can conflict with site safety rules. The WireBox-XL Tr clips over the terminal area once cables are dressed and connected, forming a physical barrier without affecting the ventilation or thermal behaviour of the controller.

This WireBox is model-specific. The XL Tr variant matches the larger footprint of the 85A and 100A Tr VE.Can controllers and will not fit the standard, non-Tr MPPT housing. Installers working across several MPPT models should check they have the right WireBox variant before ordering.

Applications

Used on commercial and industrial solar installations where terminal protection is required by site safety rules, in off-grid battery and plant rooms, and in marine or vehicle installations that need enclosed, tidy DC wiring at the charge controller. It also suits any installation where a clean finish and compliance with local wiring enclosure standards matter.

Installation notes

Fit the WireBox-XL Tr only after all DC cables have been connected and dressed at the charge controller terminals, and isolate the charge controller before making or adjusting any wiring. Installation of MPPT charge controllers and their DC wiring should be carried out by a qualified electrician or accredited installer familiar with high-current DC systems. For grid-connected solar PV systems in the UK, G98 or G99 compliance requirements apply to the wider system design.
