Victron MPPT WireBox-XL Solar Controller Terminal Cover

The Victron MPPT WireBox-XL covers exposed DC terminals on compatible large solar charge controllers. It is intended for Tr 150-85/100 and 250-85/100 controller configurations. Its purpose is to reduce accidental contact with live terminal screws after the solar wiring is completed.

A terminal enclosure is particularly useful when the charge controller is installed where people may reach around the equipment. The WireBox creates a more finished boundary around cable terminations. It does not replace circuit breakers, fuses, or the main enclosure requirements of an electrical installation.

Check the controller model and terminal arrangement against the WireBox-XL fit before ordering. The cables must be routed into the cover without sharp bends or damaged insulation. After fitting, access to the controller body and required servicing points should remain practical. Browse more battery charging accessories at CritPro.
