How Many Watts of Solar Can You Put on a 100 | 50 amp Victron MPPT Solar Charger 

Another great video. Thanks. Another benefit of over panelling is you begin to get power from the sun earlier in the day and later in the day as opposed to fewer panels.

Folks there are some very good charge controllers out there But I recently purchased a VICTRON CHARGE CONTROLLER 100-30 There are no words to explain this product but I can tell you in my words that the quality & the workmanship of this product is second to none. I am so taken back on how beautifully this equipment performs. The reviews of this product is right on and I highly recommend on a scale 1 to 10 9-1/2 seven STAR

Thanks! I was concerned about going with 820 watts. This puts me at ease.

On my 100/50 with 2x2S setup of 545W PVs i maxed out close to 1500W, on 24v AGM batts. With 5v usb active cooling fan in it, otherwise it throttles down. ;) Over half a year on this setup.

You are safe to overpanel as much as you like too, as long as the voltage is below the first number on the Victron. The Victron will just cut the amps back to the second number and that is on the batteryside. So wih the 100 50 just stay under volt and repeat in parallel as much as you want. Your 12 volt battery will take in only like 600 watt from your production. The thing is, most setups with panels will only produce their peak production during one hour a day, the rest will be less. You can solve that by rotating one 100 string of panels towards the east, one string to the west and if you have a third string, turn that to the south. That way you spread the production over the day allowing more Ah's to enter your battery over a day time. Also, aim them vertically for wintertime, not for summertime.

I had read in some victron info once that talked about over paneling victron charge controllers to 1.5 there watt rating. As long as the panels are under the voltage rating

I have a Victron 100/50 on a 12v system supplied by 1620 Watts of solar.....handles it fine and is great on dull/cloudy days....this point is missed by so many people, especially as panels are so cheap to buy these days.

I have 6 x 200W 24V panels run in parallel installed flat on my rv with this controller. Here in the pacific northwest, it works great. Allows me to max out the controller from 11-3 to bring my 3x100Ah batteries to 100%. thanks for sharing.

Great answers to the over paneling question, thank you

thanks for that, I was thinking about plugging 2x 430W flexible panels into my 100/50 charger, so it looks like it will work.

Can never go too heavy on solar, other than what your budget allows. As time goes by you can get another charge controller and batteries and make a parallel system to power different stuff.

IV a epever 100/40. IV got 3 pairs of 260w= 1560w max IV way over panelled it more for winter months. It works fine. Only thing IV done is mounted both my charger controllers on a 24"x24" aluminium plate with air gap to back of....this really does help keep them cooler.

Thank you for the video. Now I can comfortably put 850 on it.

The Victron won't begin de-rating the current until it hits around 60C (140F). Victrons can run indefinitely at their current limit, 50A in this case. The max wattage is strictly a function of the output voltage x 50A. 12V battery bank x 50A = roughly 700W 24V battery bank x 50A = roughly 1280W 48V battery bank x 50A = roughly 2750W (not the 100|50 model which is only 12/14 though) Generally speaking, this is why, in modern times, people constructing new systems should go straight to 48V battery banks. More power for less amps and far, far fewer wire losses.

So with a dual battery system at 24V you could get double the wattage right?

it would be a good idea to also go thru the interpretation of the ratings of the control device

It seems to me this is an example of why going for a higher voltage system is a good idea. That relatively affordable 50 amp Victron SCC wouldn't be clipping your panel output if you had a 24v battery... You'd be cruising along at around 30 amps: a nice, comfortably output for the SCC. With the setup shown, it is possible you'll wear out your SCC sooner running it at its 50 amp maximum for portions of the day.

Okay you seem to know what you’re talking about👍 I have 2x 200 amp 12 volt lithium batteries in my pop top caravan. I want to mount solar panels on the roof. Weight is important as I have push it up. would you use 4wd type or domestic. Should I run the panels in series or parallel, and what specs should take priority when buying the mppt. Thanks

Pretty easy, battery voltage multiply with max. amps of charger. Uploaded a movie few days ago about this topic too..... Have fun experimenting.

I have this exact same charge controller and eight100 W Renorgy Solar panels I have plans to try to do four in series and another four series and then parallel everything together and bring it in that way do you think this would work for this charge controller it will be on 12 V system with lifepo 4 batteries

Question. What about the VOC rating? Some say that is what counts.

Wire your panels in series not in parallel or at least make sure you alternate?

i push 1600w through my 100/50 victron and has not missed a beat in 3 years do you think it's to much

When you’re talking about your 50 A, your reading battery amps. your controller is capable of handling 50 A of PV looks like you only have 9 amps of PV input. You can put 40 more amps in from PV if I’m not mistaken.

Thanks for the video. What model was that Victron by the way?

I have a 555 watts solar panel & a 12v 100ah battery. What MPPT charge controller should I use on these?

Hi i have 2 of those 100/50 24v sistem with 6 320w panels each 12 total over paneling in P.R. over 93f temp they get super hot ,like you said they don't throttle down ,but i my case was cheaper to get panel than buy a new charger controller, so i decided to over panelling they max out 2800w i have 12 x320 =3800w if they broke i buy bigger ones 🤷

With the controller you have, the 50Amps rating is the maximum output ................... NOT input. It is only capable of handling 100 VOLTS on the input side. I donot think you understand the basics of electricity. Watts = Volts X Amps. So naturally when the voltage rises so does the watts.

Can you tell me what panels you were running in this video? I have some that look very similar, and make the same output. I’m assuming you’re running these two in series, If they are the same as my panels, it exceeds 50 V

The manual only gives nominal figures. For SmartSolar 100/50 its 700W and 1400W with 12V and 24V setup, respectively. I couldn't find a max value though. I prefer how Epever reports their maximum power as 1.5x the nominal power. They also state what happens when you operate above nominal - controller limits power to nominal value. I wish Victrons documentation was better. They have a good reputation, but ive found many problems in their documentation. For example not stating equipment compatibility clearly, not giving all dimensions on their drawings, and not stating absolute maximums (which is typical for all electrical equipment). I did expect higher from the industry leader.

What display are you using?

my 100/50 goes into an over heat protection?? after about an hour of full output. It then starts outputting around let's say 30-100wats or there abouts alternating up and down, and i have not observe it recover from this unless output it switched off and on again. If I dial max amps down to 40 it doesn't seem to do this. I thought I has it solved when I set up a pc cooling fan to aid in cooling, but now observed it's doing it again. there is not much advantage to my existing 100/30 charge controllers that have never de rated. Ambient temp is around 20c or less.

Good infor.❤

I have a 100/30 victron mppt . What about 3 200w panels at open circuit 28v in serious? They will be laying flat.

Hey dear I am facing power dropping issue in series connection. I have connected 340watt and 380watt solar panels in series to epever 40A mppt controller with 12v battery. It show power of one panel when I disconnect solar connector and reconnect, the mppt show both Panels. It’s hard to do this every morning. It was fine in winter but now summer starting and facing this issue. Using both panels form 2 months. after wire disconnect and reconnect the voltage jump from 33-36 to 75v. If something wrong with one solar panel then it should not work after replugging mc4 or solar wire in the mppt after that It work whole day but same issue next morning Both panels volts amps are little different. Tesla 34.51v maxpower 33.18v. Tesla amps 11.01amps maxpower 10.29amps.

Learning a lot with your videos.. much appreciated ! this might be a very basic question but I noticed you where only getting 8/9 amps from the panels but the Victron boost that up to 50 amps? to the batteries.... I bought a Victron 100/30 and with 720 watts 4X180 watt panels in series... I usually see 20 maybe 22 amps max out to my batt. ... so If I upgrade to a 100/50 like you have I would get closer to 50 amps ? I get about 8 amps coming in from my panels as well.

right now i have 290 watts of solar. is it a bad idea to get a 50amp when i dont immediately plan on expanding panels

Hi There. So the 100/30 should be able to handle good 1.000W on 24v?!

Did you have the panels wired in series or parallel??

PLEASE HELP HERE. I BOUGHT 200AH X 2;100V/50A VICTRON CHARGE CONTROLLER AND 545W X 2 CANADIAN ; IS THIS CHARGE CONTROLLER NOT GOING TO BE OVERLOADED

Were you running them in parallel or series ?

Haha I liked for your thermometer 😂

Those 455 W solar panels wired in series will have an open circuit voltage above 100 if it’s cold outside and you will damage the charge controller. Why not just put those big panels in parallel and you won’t have to worry about it. I have a leaven 400 W solar panels wired in parallel with a charge controller and it doesn’t seem to affect it at all it’s a good producer during cloudy weather. I have five separate charge controllers parallel to my battery bank 11 kW of Solar 34 kWh of battery

For a 48 v system what solar charger would you suggest…? I’m running both lead and lithium banks….

I hope you can help me 😢. I just got a I 150/60 victron controller. “Running for a week just fine” on 16 - 12v/100w panels in parallel. I was told to cut down to eight panels :-(. I don’t want to lose the amps Will the controller throttle down the watts? Will what I have continue to work? Think You for your feedback.

If i have four 200 watt panels snd a 460ah 250bms 12volt battery what solar controller eould you recommend?

It's my understanding that you don't max. out yr controller. This is so on cold mornings. It's better to use a conversion figure like 1.1 for voltage & 1.25 for current to figure out the correct controller size? Regardless, do your homework first & do consult with a qualified person if you are not 100% sure.

What the minimum watts or amps

Those handheld spot radiometer‘s are not reliable. They are way too broad in range of error. depending upon your phone type, you could get a reasonably good handheld adapter to your phone and actually see what you’re measuring. A lot of heat comes off of the back of that unit which is supposed to.

I max mine out at 1450w at 27v puts out 50amps gets hot

Derating should happen above 40C (104F)

I think you have the panels in parallel rather than series in parallel the amps out are added but in reality you should be exploiting the mppt controller for its max pv in other words panels in series your average solar of 450 watts 450 divide volts eg 30v=15a or if its 40v panel 450/40 its 11.25a in parallel its 2 times these figures so 30a or 22.5a all within the capability of that victron then if you wire in series the amps dont double the volts doubles to 30=30v all within the pv spec of the victron so i have no idea what is happening here in truth in series you could have 3 panels on

What about at 24v ;-)

i don't know what you are trying to prove here this controller can take up to 1400 watts according to the manual. just don't go over 90v or the controller will luck up

No more than- 100 volt input … series parallel..more power

It says 100V 50 amps. That's 5000 watts. Minus internal losses and voltage drops.

i was told this charger can handle up to 700 watts

If u can read the manual - u dont need to "test" something out.....

"..so we can afford a better one, how about that?" 90 degrees Fahrenheit... Start using the international measurement system, the one used in all the world,. What about that?

so how many wats of solar panels can you run on 100/50 solar charge controller? Dude I hate these videos where you don't answer you own question .

No lo vas a sobrecalentar al grado que buscas a 12 voltios solo estas usando el 50% de su capacidad 😂😂😂😂😂

and change the title of your video, it's confusing ... thank you....Dude :)

IT'S IN THE MANUAL!!!!. you can put all the power you want until the pvs exceed a short circuit current indicated in the manual. and if you do, the reverse polarity protection just doesn't work. you can put 1000w on a 30A mppt without any problems. do you read the manuals before talking nonsense?

Your numbers are all bs . If you talk about input and output ,you need to define your system . So 50 amps at what ? , your system runs at 12 v ,50 amps at 48v is 4x the energy. So at 48v your panels (your numbers) would be like 3600 w at 48v or 900at 12 …….

straight to the point... love it.. i sub

That 100/50 seems to be the sweet spot price vs. capability. Then try to get more with 24v or more.
