Victron Energy SmartSolar MPPT Solar Charge Controller 100V, 50A, 12/24V

Title: Peace of mind is worth every penny — From PowMr headache to Victron perfection Beginner mistake on my off-grid solar journey: when I first bought an MPPT controller, I opted for a PowMr 60A. The price and specs looked great on paper, but the setup turned into a nightmare. I watched thousands of YouTube videos, strictly followed the manual, and even consulted AI, but I could never get the parameters where they needed to be for my setup (a 2.56 kWh LiFePO4 battery and a 600W panel). I was never confident in how it was running. (you can see my old setup in the photos). After more research, I decided to give the Victron SmartSolar MPPT 100/50 (with built-in Bluetooth) a shot. What a world of difference! Installation was smooth, configuration via the app was effortless, and monitoring is seamless. Having previously installed a Victron SmartShunt, I already knew how reliable their ecosystem was, and this controller confirmed it. Yes, Victron is more expensive, but the build quality, rock-solid reliability, and user-friendly app give me absolute peace of mind. Sorry, PowMr!

Simple to install and app works great but does have a bit of a distance issue with bluetooth, so link your device in close range first. Too bad this device isn't rated at 120V to include 3 series 33V panels.

This just plain works. Connects via Bluetooth. Until recently, only the Victron Connect app on ios or android worked, but they recently released a Windows version that works. I find the screen size on a phone and tablet to be inconvenient, so the upgraded Windows app is a good thing. The BT protocol is somewhat open, so I monitor (not control) with a Raspberry Pi.

I purchased this to upgrade from the victron 100/30 to the victron 100/50 . I expanded to 600 watts of solar and the 30 amp controller clipped the power at about 427 watts. With the 50 amp controller I can now harvest all 600 watts at about 48 amps..depending on battery voltage. I will drian the 100ah lifepo4 down to 57% and it will be in absorption and float by noon. Awesome Bluetooth app .i have been able to connect to it at over 30ft away. I used an old spare phone as a dedicated Bluetooth monitor. If you go into the settings there is a way to keep the screen on continuously without fading to black . A nice little work around if you want a monitor without spending a lot of money. This controller is the best quality I know of. Camping in the boondocks i needed something reliable and that would grab every ray of sun possible,especially in dark short winter days.this is the controller for that.

Wanted to say thank you. The MPPT allows me to see how much solar power my panels are putting out. And how charged my batteries are. It's great.

Runs and built like a tank. Accidentally got my polarities swapped. Unit protected itself from a short and has been working perfectly fine the last 2.5 years.

This is just to provide some comparison between these MPPTs when i am in search of one that suit my needs. The test being done in various conditions, multiple PV configuration and repeated at least 3 times to eliminate some 'quick and easy' judgements. Honest observation during test found that each MPPT here has their own 'strength' and 'weakness', but all seems are good quality one. None of these result determine anything about 'reliability' and 'longevity' of the MPPTs and no intention to favor one from the others as they are different from their price point and strength/weakness as mentioned above. And by no means this was the 'absolute' result since product batch, setup/configuration and environment condition may differ from time, application and place perspective. Component of tests: - 4 x 300W Monocrystalline Solar PV - 280Ah LiFePo4 Batt 12V - 150A Smart BMS - AMPINVT MPPT 150/40 - EPEVER MPPT 150/40 - VICTRON SmartSolar 100/50 (*) Victron is the only MPPT has higher specs of amp (50A) while the other 2 are 40A, but AMPINVT and EPEVER has higher volt (150V) compare to Victron (100V) Key Performance Indicator: - Tracking time and amount of current (amp) generated in various conditions a) Series/Parallel, and combination of Series and Parallel of PV b) Combine multiple MPPTs (parallel) in same system c) Cloudy/Shading and Full Sun radiation performance Test Method: - To measure the current generated by each MPPT, i use the battery BMS across all the MPPTs so this will eliminate AMPINVT/EPEVER/VICTRON specific calculation and calibration on each of their device. - Using 'external' amperemeter (BMS) will make the judgement square and fair between the 3 MPPTs and objective(not subjective as per vendor specific) Build wise 1) AMPINVT - If i could choose, i would like all the MPPT being build like AMPINVT. - It is very nice solid metal all-round, 2nd most heaviest and the connector style for batt and PV are full clamp type which is good one. - The only complain on this 150/40A series is the connector very small for 4AWG cable size (batt), it is impossible to fit in 4AWG cable in the batt connector. 2) EPEVER - The heaviest and biggest among the 3 MPPTs and the shape a bit awkward for me - Solid build and provide more heat-sink surface to dissipate heat - Among the 3, the connector type on EPEVER is the worst in my opinion, it was 'pinch' style with screw so it doesn't have good amount of contact and holding power, however the connector size is HUGE!, 4AWG size is not a problem at all. 3) VICTRON - Being the smallest (less than half-size of EPEVER!) and the lightest of all - All metal case with heat-sink on the bottom - Connector style similar to AMPINVT and the size is also small, impossible to fit 4AWG cable size! Tracking Time - No doubt AMPINVT is the clear winner here for tracking time, it is very fast compare to VICTRON and EPEVER, VICTRON took almost double the time to reach maximum power point while EPEVER being the slowest of all. - However, this is very important and i almost didn't notice it first till i repeated the test , albeit AMPINVT tracking time is the fastest, the amp generated is not steady, it is fluctuate between 2A(min) - 6A(max) from the max current generated, it seems AMPINVT was 'very active' re-scanning the maximum power point in looping mode and sweeping through the current between 4-7 seconds. - Due to unsteady current generated by AMPINVT, this may reduce the total amp-hour produced even though the tracking time is the fastest (quick/shortest). Cloudy Day - In 2S PV setup, all 3 produced very similar amperage. - In 2S2P PV setup, VICTRON has perform slightly better on cloudy day (by 0.3A - 0.6A) after multiple test reading, while AMPINVT being the last one. Shading Problem - In 2S PV setup, VICTRON and EPEVER produced slightly more amperage compare to AMPINVT. - In 2S2P PV setup, 2 out of 5 test reading shows EPEVER generated slightly more amperage compare to VICTRON (by 0.4A - 0.8A) Full Sun radiation - In 2S and 2S2P PV setup, i can't really tell since the max amperage for AMPINVT and EPEVER already reached (40A), while VICTRON has 50A max, thus VICTRON constantly produce more amperage by 6A-8A higher than the others. Conclusion - AMPINVT has very attractive price point, pretty compact but loud (fan noise) and the really downside is 'unsteady' amp generated, however if system small enough (less than 600W) with 2S PV config only and very limited budget, i think AMPINVT is quite difficult to resist here, since the remaining 2 options is twice or thrice the price. - VICTRON is long known name in MPPT worlds, no doubt it could be the best and the test result telling not far from the tale, however this is the most expensive one in the 'similar' class, if budget is not an issue and you want to build very compact (small) system then it is no brain to not pick up this one. - EPEVER, this MPPT perform similar as VICTRON in many ways and perhaps slightly better in shading scenario, can do over paneling up to 3x the power specs (3x520W=1560W) is huge advantage but due to size you need bigger space, but i guess the the best bang for the buck on this class.

Ich habe mir eine kleine Solaranlage aufgebaut und mich für den Victron SmartSolar MPPT 100/50 entschieden. Mein Ziel war es, ein hochwertiges Gerät zu haben, das die Batterie ordentlich lädt und so ihre Lebensdauer verlängert. Freunde von mir nutzen diese günstigen chinesischen PWM-Regler – der Unterschied zu meinem Victron ist einfach gewaltig und gar nicht zu vergleichen. Das Gerät ist massiv, schwer und man merkt schon an der Verarbeitung, dass das kein Spielzeug ist. Was mich am meisten begeistert hat, ist das integrierte Bluetooth. Über die VictronConnect App sehe ich in Echtzeit alles: den aktuellen Ertrag, die Batteriespannung und die Historie der letzten 30 Tage. Die Koppelung über Bluetooth hat völlig problemlos funktioniert. Man braucht nur den PIN für die Verbindung, der beim Gerät dabei war. Es wurden zwei Aufkleber mit dem PIN mitgeliefert – einen habe ich direkt auf das Gerät geklebt und den anderen für meine Unterlagen mit nach Hause genommen. Auch die Installation der Kabel war super: Ein 16 mm² Kabel passt problemlos unter die Anschlussschrauben und man kann alles richtig fest anziehen. Die MPPT-Technologie ist erstklassig. Ich habe gemerkt, dass er selbst bei bewölktem Himmel oder tiefstehender Sonne noch Strom rausholt. Ich nutze ihn in einem 12V-System und er wird absolut nicht heiß. Das Gehäuse aus hochwertigem Kunststoff und Aluminium leitet die Wärme top ab. Außerdem kann er tiefentladene Batterien wieder "aufwecken", was die meisten anderen Regler nicht schaffen. Fazit: Ich bin sehr zufrieden. Wer ein kleines Solarsystem aufbaut und seine Ruhe haben will, sollte zu Victron greifen. Er ist teurer, aber wegen der Sicherheit und der Bluetooth-Funktionen lohnt sich die Investition definitiv. Bewertung: 5/5

Bon produit et efficace 👍

Good

Très bon régulateur de charge. Beaucoup plus meilleur que du matériel chinois. Il détecte d'entrée la technologie de vos batteries et utilise son système MPPT pour mieux contrôler la gestion de vos batteries

A few years ago I bought a complete 24v off grid kit from a provider of end-to-end solutions. This for an off grid office I use as my daily workplace. The kit included a different brand of charge controller. Hell, I've been tinkering with that MPPT for years always suspecting something is just not correct. Finally I thought I'd try this Victron CC and it has made an amazing difference. Mainly it keeps the batteries in better health. For the saving of my anxiety of battery state alone it's well worth the extra £50 of the origanl. In terms of how the Victron is better at managing the battery bank it's probably going to save me hundreds, if not thousands! I've done so much research and I cannot find another MPPT that comes close to Victron's ability. It's small, build quality is excellent, setup is simple with the Victron app. I'm now a total convert to this brand.
