The Victron MPPT WireBox-S is a clip-on terminal cover for the SmartSolar and BlueSolar MPPT 75/10 and 75/15 charge controllers. It fits over the wiring area once cables are connected, enclosing the terminals and giving the installation a neater finish.

Key features

• Fit, designed specifically for the Victron MPPT 75/10 and 75/15 charge controllers.
• Coverage, encloses all wiring terminals once cables are connected, reducing exposure to live conductors.
• Weight, 0.1 kg, adding minimal bulk to the installed controller.
• Fitting, clips on without extra tools or fixings.

Product overview

The WireBox-S is a terminal cover accessory for the smaller controllers in the Victron MPPT range. Once the solar, battery and load cables are connected to the MPPT 75/10 or 75/15, the WireBox clips over the terminal block to enclose the wiring. This suits installations where the controller sits somewhere accessible to non-technical users, or where a tidy cable entry point matters.

The cover has no effect on the electrical performance of the charge controller. Its job is mechanical: covering exposed terminals and reducing the chance of accidental contact or debris around the wiring area. In caravans, boats, cabins or small off-grid systems where the controller is mounted in a visible or shared space, it is a simple way to meet basic wiring safety expectations.

Applications

• Caravans and motorhomes with the charge controller mounted in a habitable space.
• Narrowboats and leisure marine installations needing tidy terminal management.
• Off-grid cabins and garden buildings where the controller is visible or accessible to non-technical occupants.
• Small solar installations requiring a neat finish for customer handover.

What's in the box

• 1 x Victron MPPT WireBox-S 75-10/15 terminal cover

Installation notes

Fit the WireBox-S after all wiring to the MPPT charge controller is complete and checked. Make sure connections are correctly torqued and the controller is powered down before fitting the cover. The underlying wiring of a solar charge controller should be carried out by a competent person familiar with DC solar systems.
