Victron MPPT WireBox-S 100-20: Professional Terminal Protection for Solar Charge Controllers

Enhanced Safety and Clean Installation for Your Solar Power System

The Victron MPPT WireBox-S 100-20 is a purpose-built terminal cover designed to add an extra layer of safety and a professional finish to your solar charge controller installation. By enclosing all DC terminals, it prevents accidental contact with live connections, making it an essential accessory for systems installed in general access areas such as caravans, RVs, marine vessels, and off-grid sheds. This durable enclosure not only reduces the risk of short circuits and electrical hazards but also provides effective cable strain relief and tidy cable management, ensuring your setup remains secure and visually clean.

Engineered specifically for the Victron SmartSolar and BlueSolar MPPT 100/20 charge controller, the WireBox-S 100-20 integrates seamlessly with your existing hardware. Its impact-resistant black plastic construction is built to withstand the rigours of mobile and stationary environments, while the snap-on design allows for quick, tool-free installation. Whether you are upgrading an existing system or commissioning a new one, the WireBox-S 100-20 delivers peace of mind by keeping your wiring protected and your connections out of sight.

Why Choose the Victron WireBox-S 100-20?

In any solar installation, exposed DC terminals pose a safety risk, particularly in environments where untrained individuals or children may be present. The Victron WireBox-S 100-20 mitigates this risk by completely covering the terminal area, reducing the chance of accidental shorts, corrosion from environmental exposure, and inquisitive contact.

For installers, the WireBox-S 100-20 simplifies compliance with Australian electrical safety standards by providing a robust physical barrier. It also enhances the aesthetic of the installation, concealing unsightly wiring and creating a clean, professional appearance that reflects the quality of the Victron ecosystem. The thoughtful design includes removable cable entry inserts that accommodate various cable diameters, allowing for flexible routing while maintaining a sealed, protected enclosure.

Applications

  • Caravan and RV solar systems where space is tight and safety is paramount
  • Marine and coastal environments requiring protection from salt mist and moisture

  • Commercial and industrial solar arrays where professional finish is expected
  • Educational and demonstration setups where terminals must be guarded

Great for the price
Size: 1 Kit, Size: 1 Kit
Worked great at clearing my headlights and at a great price, I had used a different headlight kit maybe 5-6 months before and it did not perform as good as this kit did, maybe it was a user error with the previous kit but this one cleared it easily and was very easy to do and had a nice clear shine.

I'm Not Disappointed ...
Size: 1 Kit, Size: 1 Kit
I knew going in that my expectations shouldn't be very high because my car is a first generation 2010 Kia Soul. So its old with 16 plus years of yellowing oxidation and some abrasion. I took a chance with doing this because of the reviews and pictures. To my surprise, it worked better than I anticipated and could hope for. My driver side(left) headlight was horrible but my passenger side(right) wasn't too shabby and didn't require as much care. This would have turned out better if I had power drill attachments of the same sanding grit to do this. My arm is going to be really sore come Sunday. 😆 It wasn't too hard to follow the instructions as they were very simple for the application process. I don't know about the 2 years for it lasting, but for now, its durable. Once I drive at night, I'll be able to But all in all, it worked for me and its better than before I tackled it. All in all it looks good, I feel like I'll have a better beam when night 🌙 driving.

Let this restoration kit light up your life
Size: 1 Kit
I have a car that is 24 years old and is my daily driver.  Understandably, the headlight lenses have deteriorated to the point where I was using my brights exclusively at night yet never being flashed to turn them down.  I got quotes between 60-80 dollars per headlight for restoration which I just wasn't willing to pay so I decided on this kit to try restoring them myself.  I read reviews before I ever make a decision on a product and noticed many reviewers of other products stated that this product works better so I went ahead and purchased it.  Man, am I glad I did!!!   The kit arrived late this afternoon, I opened it, READ AND FOLLOWED THE INSTRUCTIONS and within 1 1/2 hours had turned a travesty into a triumph.  I started by taping around both lights with 1 inch blue painters tape to protect the paint around the lights.  The kit comes with everything necessary to remove most moderate deterioration but be sure to purchase one that corresponds with your actual situation.  I believe my lenses were far beyond "moderate" but with some heavy elbow grease, the correct use of both supplied sanding disks and my hose set on "mist" I was able to sand off years of damage leaving behind a smooth, albeit opaque surface.  After making sure everything was totally dry using both towels and my leaf blower, I was ready for the Magic!!!  I opened the first clearcoat package (while wearing the provided glove) and lightly but steadily applied the liquid with the supplied towelette and the required 50% overlapping passes.  The opaque lenses instantly turned clear upon contact with the clearcoat.  After waiting around 25 minutes to be sure the lenses were completely dry I opened the second package of clearcoat and applied it in the same manner as the first.  I had no misses or problems with my first coat but for those who do...NOW is the time to make corrections, NOT during the first coat process.  Leave things to dry for around an hour and you are done. The end result?  AWESOME, INCREDIBLE, UNBELIEVABLE...shall I go on???  Not necessary, but I can say I am thrilled with the outcome.  My wife said the lights look new and I agree, there is a night and day difference between before and after. Only time will tell how long the restoration lasts but for now I am very very happy with the results I got from this 3M product.  I highly recommend it to anybody who can read, understand and follow the instructions.  5 stars all the way on this one!!!
