Ultra-Fast MPPT Solar Charge Controller for Off-Grid Systems

The Victron BlueSolar MPPT 100/20 is engineered to maximise the energy harvested from your solar panels, providing exceptionally fast Maximum Power Point Tracking (MPPT). Particularly in overcast conditions or when light intensity fluctuates continuously, this advanced technology ensures you capture up to 30% more energy than traditional PWM controllers and significantly more than slower MPPT models. Designed for harsh environments, the internal electronic components are protected to IP43 standards, ensuring reliable operation in mobile, marine, and remote off-grid solar setups.

Secure, Hardwired Non-Bluetooth Design

Unlike the SmartSolar equivalent, this BlueSolar controller features a non-Bluetooth design. This is ideal for users who prefer highly secure, hardwired connections without emitting wireless signals. Monitoring and configuration can be achieved by connecting a VE.Direct cable to a Victron GX device or MPPT Control display. If wireless access via the VictronConnect app is desired in the future, a separate VE.Direct Bluetooth Smart dongle can easily be added to the system.

Important Programming Note for Lithium Batteries

Out of the box, the controller is configured for standard lead-acid and AGM batteries. If you are integrating this unit into a lithium battery system, a configuration update is required to ensure optimal charging parameters and protect your investment. This can be managed through one of three methods: using a VE.Direct to USB cable connected to a PC, adding a VE.Direct to Bluetooth Dongle for smartphone access, or programming directly via an external Victron MPPT control display.

Intelligent Load Management and BatteryLife Algorithm

A deeply discharged battery can suffer permanent damage within days or even hours. This controller features a dedicated load output with a smart disconnect function, cutting power to appliances before the battery voltage drops to critical levels. Furthermore, the innovative BatteryLife algorithm monitors the battery's state of charge. If the solar yield is insufficient to fully charge the battery over consecutive days, the algorithm subtly increases the load disconnect threshold until a full 100% recharge is achieved. This intelligent management prevents chronic undercharging and significantly extends the operational lifespan of your battery bank.

Key Features and Benefits

  • Ultra-fast MPPT tracking: Optimises solar energy yield even under rapidly changing cloud cover.
  • Outstanding peak efficiency: Operates at up to 98% efficiency with a fanless design for silent, reliable performance.
  • Intelligent load output: Protects your battery by automatically disconnecting DC loads when voltage drops to critical levels.
  • Flexible system integration: Automatically selects between 12V, 24V, and 48V battery systems upon initial connection.
  • VE.Direct communication port: Allows for advanced programming, monitoring, and integration with external devices.
  • Robust construction: Features 6mm² (approx. 10 AWG) screw terminals for secure cable termination and a replaceable automotive blade fuse for over-current protection.

Additionally, this specific model supports automatic detection for 48V battery systems, providing scalable flexibility for larger off-grid energy storage setups.

Works like a champ!
Size: Full-size Truck, SUV
It works great! I had one fairly slow leak and 2 very slow leaks. 3 Tires. 2 were on my 94 Ford Ranger. I put a little more than 1/2 the packet in my fastest leaking tire (on the Ranger) and about 1/4 of the packet in the 2nd tire of the same vehicle. Lastly, I put the final 1/4 in a very slow leaking tire on my 2000 Ford F-150. All tires have stopped leaking!! I am delighted with the effectiveness of this product!!

Seems to have done a great job.
Size: Full-size Truck, SUV (2-pack)
One of our cars has suffered from rim leaks and was driving me nuts. Constantly being asked by my wife to top off the tires on her car. When I replaced a damaged rim I asked the tire shop to look for the source of the leaks. They said the "alloy" rims had started to corrode and did their best to get them to seal but warned me they would likely leak again. This spring when I removed her snow tires I found 3 of her 4 tires had gone completely flat in storage. The fourth was the new rim which was fine. I considered buying new rims that won't have this problem but wanted to wait until her times need to be replaced. The batteries in the TPMS sensors are getting very low so likely these will need to be replaced as well. I thought to try some sort of sealant. Most of the products I saw were not rated for automotive systems and offered warnings about risk to the TMPS sensors. This seemed to be the only product rated for my application and claimed it would not harm our car's sensors. So I gave it a shot. I ordered the SUV package that came with an injector and two 8-oz bottles. I put 4 oz in each tire per the instructions. Overall the process was easy except the valve core extractor broken on one of the tires. I had to pick up a replacement at a local auto parts store. Also, injecting the sealant creates a small amount of pressure in the tire that, if one doesn't release by drawing out the plunger, will burp a small amount of sealant onto the rims. Fairly easy to clean up with WARM water and easier to avoid after the first experience. Drove the car around at a variety of speeds for 10-15 minutes (had errands to run) and waited to see what happened. Great results. Weeks later and the tires still have the correct pressure. I am not sure how long this will last but hopefully for the remaining life of the tires at least. I took one star off for easy of use / easy to install because the valve core extractor is made of extremely cheap aluminum and I am sure others will have a poor experience with it. Be forewarned and consider buying one before you start jacking up your car and letting the air out of the tires only to find you break the tool on a sticky valve core and are unable to complete the job without a trip to the auto parts store. I'll update this review in about a year to report on the long-term outlook for this product.

It Works!
Size: Full-size Truck, SUV
When I bought my vehicle it didn't come with a spare. I knew what I was in for. I was on my way to an important meeting and as fate would have, the tire pressure indicator reported a flat. I imagined the worst but experienced the best! The directions said to let all the air out of tire and remove the valve stem core, it seemed like I was making a bad situation worse. Then it said to attach the tube to the stem and squeeze the contents into the tire. I thought "this is never going to work" the fluid seemed too watery to seal anything, but I followed instructions, I reinstalled the valve core and reinflated the tire, and it worked! I expected it to leak immediately, it didn't. It lasted all day and most of the next day until I could get the tire to the shop. They removed a nail and patched the hole, overall I'm very satisfied, I bought a replacement right away, just in case!

Better than the green goo
Size: Full-size Truck, SUV (2-pack)
Recently, while I was at work, I noticed that I had at some point run over a nail with my car. Normally, you'd take your car to the tire shop and let them plug the hole for you. Well, the only problem was that the nail decided that it was going to poke my tire where the sidewall meets the tread, and most shops will refuse to plug a tire when it's punctured there. Makes sense, it's a liability issue for them, so I can't blame them. That still leaves me with the problem of having a tire with a nail in it. So, I could either replace the tire with either a new or used tire, which is expensive or I can try using a sealant to try and get as many miles out of my tire as I can. In the past, I had tried using the green goo sealant on nail holes, and while it works to get you 15 miles down the road, that's about it. Now, while TireJect doesn't recommend using their product on punctures on the shoulder of the tire, I decided that I'd give it a try to see if it would work. And as of writing this review, it's been about 10 days since I put TireJect in my tire, and so far, it hasn't leaked any air, despite it not being meant for the shoulder. When money isn't so tight, I'll probably go ahead and replace the tire, especially since there's only about 4/32 tread depth left, but for the time being, I'll keep running it, and hopefully it keeps holding pressure properly like it has been. Now, as for how easy it is to use, the only tools you will need that aren't provided, is an air compressor to allow you to re-inflate the tire. The kit comes with everything else you will need, including a valve core removal tool and a syringe to add the sealant to your tire. To use this product, you will first need to carefully remove the valve core with the provided tool, careful not to lose the core, since it doesn't come with a replacement core. After that, thread the hose on the syringe on to your valve stem, and then carefully add the required amount of sealant to the syringe. If you accidentally spill some, wipe it off before it dries, so that it doesn't stain anything. From there, just push the goo into the tire with the plunger, adding more to the syringe as necessary. When you're all done, re-install the valve core into the valve stem snuggly, careful not to over-tighten, and air up the tire to the recommended PSI with your compressor. After all that is done, go take a short, slow drive to distribute the sealant, and then recheck your air pressure.

TPMS Compatability is a LIE
Size: Sedan, Crossover, Small Truck
2018 Subaru Impreza, with one tire with a slow leak (about 2 PSI a week) that I couldn't trace. I bought the "Full-Size Sedan, Small Truck, Crossover" kit (the 6 oz. pouch) based on my tire size, 225/40/18. After I removed the valve core, attached the dispensing hose and opened the cap, the product would not flow into the tire. I squeezed the pouch, but that only made the product leak out around the valve stem onto the wheel and driveway. I tried rotating the tire so the valve stem was at the top, and and also at the bottom. I even took the wheel off so I could get a fully vertical flow. Nothing worked. I finally gave up after only about half the product was dispensed, and I do think most of it went somewhere other than in the tire. I reinstalled the valve core, remounted the wheel, plugged in my little lighter socket-powered compresseor, and tried to inflate the tire. And ... NOTHING. The pressure reading on the compressor immediately shot up to over 100 PSI, and it automatically shut off. Tried multiple times, with the same result. I again removed the valve core, and a) no air came out of the tire when I removed it, and b) even with no valve core the compressor still would not pump air into the tire. Clearly the gunk had completely blocked the valve/TPMS. Fortunately, when I took the tire to Costco (where I'd bought it), they were able to fix the damage I'd done, as well as patching a small nail hole in the tread I hadn't seen (that was clearly the source of the slow leak) for no charge. Since I've already submitted a refund request, ultimately all it really cost me was my time and effort ... and a whole lot of stress.
