Victron MPPT WireBox - Tr (Screw Terminal Models)

A protective cover for the DC screw terminals of your Victron MPPT solar charge controller. The MPPT WireBox snaps over the exposed PV and battery terminal screws, adding a layer of safety that's especially useful when the charge controller is installed in a general-access area - it prevents accidental or curious contact with live terminals.

This is the Tr (screw-terminal) version, sized to match the SmartSolar and BlueSolar MPPT models that use screw terminals rather than MC4 connectors. Choose the size that matches your exact charge controller:

• WireBox-S - for the smallest MPPT models: 75/10, 75/15, 100/15, and 100/20 (a dedicated S box for each).
• WireBox-M - for the 100/30, 100/50, and 150/35 models (5.1 in tall).
• WireBox-L Tr - for the 150/45, 150/60, 150/70, 250/60, and 250/70 screw-terminal models (6.9 in tall).
• WireBox-XL Tr - for the 150/85, 150/100, 250/85, and 250/100 models (8.5 in tall, Tr and Tr VE.Can).

Covers all DC terminals (PV in and battery out), quick to fit, with no rewiring required.

Important: the WireBox must match your specific MPPT model and size. Check your charge controller's model number against the variant options above, or contact us and we'll confirm the right fit. (For MC4-connector MPPT models, see the MPPT WireBox-MC4.)

Pairs with: Victron SmartSolar and BlueSolar MPPT charge controllers and MC4 solar cables.
