Handles the big controller with ease
Mounted my SmartSolar 250/100 in this and the fit is perfect. With 100A of current flowing, proper terminal protection isn't optional, and this enclosure delivers. Everything is rock solid.

Professional finish on a large install
We run three 250/100 controllers on our homestead and each one sits in a WireBox-XL Tr. Terminal covers, clean cable management, and code-friendly layout — at half price it costs less than the wire lugs. Four years' worth of trust in Victron gear continues with this accessory.

Does the job, wish it were cheaper
It's a decent enclosure for my 150/100 and the plastic is certainly sturdy. But it's essentially a molded cover, and even discounted it feels a bit much. Fit and finish are good though, and it does make the install safer and neater.
