The Victron Energy MPPT WireBox-L Tr is a protective terminal cover for compatible SmartSolar MPPT charge controllers with screw-terminal connections. Designed for 150/60, 150/70, 250/60 and 250/70 Tr models with a 200 mm enclosure height, it covers the DC terminals to reduce accidental contact with terminal screws.
The wirebox mounts directly to the charger and is especially useful where the controller is installed in an accessible area. Its fitted enclosure improves installation safety while keeping cable entry and terminal connections neatly protected. The purpose-built design helps create a cleaner, more enclosed finish around the controller wiring
