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.

Enhance Your Off-Grid Power Today

Investing in high-quality MPPT technology is the most effective way to extract every available watt from your solar array. With its robust thermal management, programmable algorithms, and secure hardwired configuration, the Victron BlueSolar MPPT 100/20 delivers industrial-grade reliability for your caravan, boat, or remote shed. Secure your power supply and maximise your solar potential by adding this charge controller to your system today.

Stick format is thick and difficult to rub in moderate climates
Style: SPF 50, Size: 1 count (Pack of 1)
I wanted to like it because the small stick format seemed very convenient to keep in my bag for emergency sunscreen reapplication with no chance of leaks. But I think I have learned my lesson about stick sunscreen - in order to hold together in a stick, it has to have a thick and chalky consistency. Which makes it hard to apply and hard to rub in. It's so thick that if I rub the stick over my entire face it feels like I'm applying way too much with a super heavy white cast, and if I dab here and there and try to spread it around, it's so thick it doesn't feel like it spreads into good coverage. The scent is fine. Update: I have found a specific use case for this - in extreme UV conditions like the equatorial tropics in midsummer, it's a good base layer under a more liquid mineral sunscreen, to add extra protection to the most exposed skin, like tops of shoulders, chest, nose and top of forehead. The thickness makes it protect better. It also softens a little and rubs in better in hot temps.

Needs to be warmed, but works great for quick face re-application
Style: SPF 50, Size: 1 count (Pack of 1)
I love mineral sunscreen, it really works the best. But I also do not love mineral sunscreen because it's hard to apply. I don't think it matters what you do, they're just always difficult to apply and always leaving the white. This one isn't much different. I'm a scuba diver and my face sunscreen is washed off quickly doing multiple dives. I also get a weird "mask sunburn" if I don't reapply... but since I'm a diver I can't bring myself to buy or wear sunscreen that's not reef safe into the ocean. I was unsure if this would work because it's pretty solid. I threw it in my bag and once the sun warmed it up a little, I was able to apply it fairly easily between dives. I don't think it works unless it's warmed a bit first, but I like it for this purpose.

I Wanted to Like It
Style: SPF 50, Size: 1 count (Pack of 1)
I really wanted to like it because of the great reviews it gets with backpackers and generally with people that don't like "greasy hands syndrome" after applying sunscreen. But after using a stick I found that it's just not that good. The good: small, lightweight container. Not greasy. Good protection, I was in the sun all day hiking multiple days straight and only put on sunscreen twice per day and I didn't have any burning... and I burn easily. The bad: Value: the $12.53 sunscreen container only lasted about 8 days. And that was just my arms, neck, and half my face since I wore a shirt and long pants and a wide brim hat every day when hiking. I would expect this amount of sunscreen to last a lot longer than that on such a limited area. I'm not a big person either. Application, chafing: it's the opposite of greasy, almost chalky. You use the stick to apply to your skin in stripes, then you have to "blend it in" by rubbing with the backs of your hands so your palms don't get chalky. Since the stick is so dry this requires a fair amount of force and it chafes as you rub it around. When your skin a bit sandy it hurts. Application, crumbling: on a chilly but sunny morning, about 45 F, I applied sunscreen and small chunks of the stick crumbled off. I watched precious chunks of the already overpriced sunscreen drop to the ground. Residue: while it's not greasy, it's physical sunblock so it gives your skin the characteristic whitish sparkle. That's to be expected. But what I didn't foresee is it will rub off on anything your skin touches. My gear had white chalk-like marks (technically titania powder?) on my shirt collars, backpack straps, sunglasses, and a few other high-touch items. Overall I think it's a neat idea. I'm not overly disappointed with my purchase. But for $12.50 I expect sunscreen to be easier to apply and for the container to last longer than about 8 days. I can't burn $50/month in the summer months when a single container of chemical sunscreen will do the job. Pro tip: you can buy food-safe 3 oz TSA travel containers. Load one of those up with chemical sunscreen and you have something that beats this in every way except for the greasiness, which you can mitigate by picking a lower SPF sunscreen (the 30 SPF you wear is infinitely better than the 50 SPF you skip!).
