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.

Its fantastic it works like a clock its just plug an play you dnt have to monitor it and its easy to instal. The price is a bit tall but its woth it I've had it for months now and it just goes and i like the app its very user frendly it handles power really good i had 2 665 panels connected to it and it handle it fine and change my battery fast. The only thing is that it smalls a bit and gets hot but that's no problem for me knowing that i have no electric bill to pay. 😁😁 I've read other reviews on this mppt and they complain about the Bluetooth range but to be honest it's not bad, Bluetooth signals\ waves don't travel that far ether to that's no problem for me. Victron is good.

Works fine. Recommended

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.

This unit 100/50 mppt is a great value and performs well with small DIY systems. The BT app was easy to setup. I use it with 3 225w panels to charge a 12v 460ah Vatrer battery. I wish I would have purchased a larger unit to expand my setup.

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!
