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

This controller is a game changer. It works flawlessly and is loaded with custom features as well as a large array of default battery options. I also bought the victron battery temp and voltage sensor since my batteries are on the ground subject to different temperatures than my controller mounted inside my rv. The Bluetooth works excellent and you can see real time operation as well as historical info.

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.

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!

This was my first REAL solar build. But it didn't start out that way. I was planning on 12v because that's what Ive always done and that's what I was comfortable with. I knew my inverter needed to be replaced and I knew my wires weren't nearly big enough for my intended final wattage. So with the flexibility this offers I decided to branch out and switch my 4 batteries from 12v parallel to a 2s2p 24v bank. This move brought my wires into spec by halving my amps while allowing me to charge twice as fast. Now I wish I would've gotten one capable of 48v (or 70 amps charging) but this is big enough for my needs. I've built 2 more, smaller systems now with victron controllers. I feel so silly for basing previous systems around cheaper controllers. Victron is absolutely worth the price. I've got 6 - 200 watt panels in 3s2p pumping in a full load, 1200 watts. I've done all the things you're not supposed to do to this thing. Hooked it up to PV with no battery. Shorted the battery terminals. No problem. The Bluetooth interface is fantastic. I wish the history had dates instead of just saying "5 days ago" for example but otherwise it's great. 8 gauge terminals to get your full 50 amps. also I find it kind of surprising that these controllers don't have built in temperature sensors. not a huge deal since most BMS will handle that but extra protection always good. all in all a great controller if you have it sized right. if you have any intention of pulling more than 1200 watts or are trying to charge anything over 24v this isn't for you. If I were doing it over I'd opt for the 150/60 for another hundred bucks and start saving to switch to 48v batteries. But again that's just me being greedy and wanting to experiment. 600 AH @ 24v. 3000 watt inverter. and 1200 watts incoming because of this guy. Perfect for my off grid camp but I would most definitely need more wattage if I were cycling this every day. I'm only there 4-5 days a month so they're always full when I get back.

Works fine. Recommended

Great little MPPT controller that charges at 49.9 amps with my 800w (2x400w) array in parallel or series. *Heavy* plastic casing with aluminum frame and heat sink on the underside, the heat sink runs at about 170f when charging at the maximum 50 amps, but below 30 amps runs considerably cooler, <135f. The app works even with my Samsung tablet and phone (Samsung security protocols are notoriously difficult for Bluetooth connections), though it does take a few seconds to reconnect each time you switch windows or if the screen shuts off. The app, however, offers an option in the settings to keep the screen on until you manually close it. This is handy in case you mount your phone or tablet on your dash to occasionally look at the controller and/or shunt activity while you're driving. The wiring and setup (via the app as this controller has no built-in screen) is easy and fairly intuitive, though the terminals for charging power to the battery are a little close together with a scant 1/4" in between, so you absolutely MUST use crimped ferrules to connect them for safe installation, but really, proper connections are essential anyway. Using bare wire could lead to a short if a couple strands don't feed into the screw clamp connection hole; and with up to 50 amps of current, it may even be possible for the charge current to arc through the air and short out. The clamps will only hold a max of 6awg wire, and even then only if it's crimped very tightly into the ferrule. Proper 8awg full copper wire will, however, carry the full 50 amp charge output as long as the insulation is rated at a minimum 75c/167f. I haven't had any reason to contact the manufacturer's customer service, but they have a website chock full of previously-asked questions and answers with a ton of useful information for any diy installers or those new to solar. I also recommend purchasing one of their smart shunts for monitoring purposes. This really takes the guesswork out. It's also worth mentioning that your battery state of charge will determine how much power flows into it, and if your battery is full or close to full, the controller will limit the input from your solar panels to prevent overcharging. This is important as I often see critical reviews where the controller or panels are blamed for having "low max output" because they're connected to a battery that's at or near full charge. Occasionally, this is posted on the day after installation... "... it worked great for one day, then died out to almost nothing!" (because the battery bank was nearly full from the previous day's charging). When my battery bank is 95+% full, my power output from 2 400w panels drops down to 15w as the charger switches to float mode. At 90% it begins to taper off the amperage, and since watts = amps x volts, the panel output is reduced to help prolong battery life. My setup is specifically calibrated for maximum battery lifespan, so your setup may reduce current at a different state of charge. Overall, I definitely recommend Victron products as a result of my own experiences with them.

Returned. The existing 100/30 will continue to meet my needs. Victron is still great quality. If you want economy, you'll have to pay for it. Victron devices just plain work all the time.

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

De qualité , marque fiable

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

Excellent quality product from Victron! Works well and easy to pair via Bluetooth with the app on your cell phone which shows you all the necessary battery and solar information and setting adjustments, would recommend!
