They sent me a new Victron MPPT! Will it work this time? 

Victron isn’t cheap, well engineered quality products seldom are, but the 5 year warranty can be absolutely priceless. The other great benefit I’ve found is their technical support (they nearly always answer quickly and with practical solutions), plus the wider community of retailers and installers who know the product can also help sometimes. If you have a limited budget then you may be unable to afford their kit; but my dad always used to say “buy cheap, make sure you save for a replacement/repairs” Here is a comment from one of the community posts about the MPPT battery voltage setting: The battery voltage is automatically selected at the very first power-up of the charger. The detected figure is stored, and further automatic detection is disabled. If, however, the battery voltage is absent (or below 7 volts) the unit operates as a 12 V model and automatic detection is rescheduled for the next power-up. Note that 36 and 48 volt operation is only available on models which support these voltages - such as the MPPT 150/35. Note also that 36 volts cannot be detected automatically. Systems operating at this voltage must always be set manually. Hint: if you just want to update the firmware of a device while still keeping the automatic voltage detection active (e.g. before shipping a unit to the end customer), update the firmware as you normally would do. When the firmware update is complete, at the “Live Data Information” page select to cog wheel in the upper right corner, next the three vertical dots in the upper right corner and make sure to choose “Reset to defaults” from the drop-down menu. Now power down the unit, when the unit is powered up the next time it will perform an automatic voltage detection. I hope that helps? As for that Weller soldering iron tip, plenty of life left in it yet, just maybe not for surface mount components 🤓 All the best, stay safe.

Matthijs Vader is the managing director of Victron Energy and Son of the founder Reinout Vader! I think it's a good sign that they are involved in answering the technical questions themselves so they know what going on on a daily basis in their company! Best regards from Holland and keep up your channel.

Yes it's ok, you just change to the correct nominal voltage after connecting. Done it many times

Hey Andy, i like watching your video's very much! Just watched this one, en wish i have seen this one earlier. I blew up my victron Mppt 75/15. First i hooked it up to my 12 volt lifepo4, no problems. Then hooked it up to my 24 lifepo4 and BOOM. I thougt it automaticly detected the 24 volt. But sadly only at the initial setup. 😬

The holes for the Victron were pre-drilled in exactly the right place prior to installation.... how lucky was that!!

I thought I had OCD till I started watching the Assusie German.

I hope it works. Eagerly waiting for the new BMS installation!

You always find a way to make me happy, thank you always because I am learning a lot from me

I wonder if these solar charge controllers are getting damaged from BMS disconnect events. Normally manufacturers warn that the controller may be damaged if the battery is disconnected while the solar panels are still connected.

THANK YOU FRIEND, i really enjoi your "run" as i were there! Thanks to share

Unless the designers were incredibly incompetent, having Vmax > Vbat > Vfloat should be completely harmless since Vbat > Vfloat should simply cause the PPT to shut off. The most likely danger of Vfloat > Vbat would be damaging equipment that isn't designed to take Vfloat. Shipping the PPT at the lowest voltage preset is the safest option.

I connected my 150/35 first to 24 Volts. And than to 48 V without checking is on the PC . The Venus gave lots of warnings, but nothing broke. It was just a short time. It is working now on 48 V fine. After the initial "branding" to a battery voltage it must set manually.

You should open up both Victrons, and see if the one from ebay is different, old model, or simple counterfeit.

12/24 and 48 volts are auto select, only 36v needs to be set manually. The is the spec sheet for victron

If you would like a cheap back up controller. I use Make sky blue controllers often. If you hook them up correctly and stay below the ratings ,they work well and track fast too.

Hi Andy, great videos to watch! Would ik make sense to have a circuit breaker between your charger and mppt controller (bridged with a switchable resistor) this way you can troubleshoot and connect safely. (I don't mind de SCC 😁) but it makes handling much easier also when a problem arises at night when you don't have lights because of an issue. Speaking of that, probably you're thinking of a emergency light in the shed which will light when the power is off. Keep on making videos, we miss so much real life technique on YT

Man your video quality is great

I have the same problem with Epever Tracer 4210AN it works as PWM most of the time.If i reset the circuit breakers from the pv input it works as MPPT for a few minutes than the pv imput voltage goes down almost to battery voltage.I changed on of the controllers with victron 100/50 smartsolar and it works perfectly unlike the Epever chinese toy garbage controller.

It usually picks up the battery voltage and changes automatically.

Hi Andy what happen if you connect For example 155v. I have 3 panels each has 50v. When the weather is cold the voltage of each panels is 51v so together is 153v. Can I damage the controler? Will it endure a few more volts?

Wished Victron was making BMS with active cell balancers.

Lol! it seems we are always waiting for mail deliveries doing solar. Yes that is not a proper test only 4 days low wattage. Hopefully there will be software updates like you've mentioned. Good stuff man, cheers! 😁

Most power supplies including solar charge controllers are what is referred to as single quadrant output. That is it can provide voltage to the load, but not take it back. It can supply current to the load but no5 take it back. So if the solar controller is set to output less than the battery voltage, no damage will occur.

As a postie it is funny watching your deliveries!

I set up my smart battery protect on 12V's so that I can play with the Bluetooth. Then later went into the settings and changed to 24 V before disconnecting from 12 V's without any issues. I know it's not a charge controller but it's a Victron product.. So maybe they're similar? I have wondered this also. Oregon USA

I may have missed it in earlier videos but if you are being careful to not connect the PV before the batteries what is the protection for the charge controller if the BMS disconnects the batteries with the PV connected?

Andy do you still use your JNGE 48 volt charge controller. if not would you sell it and how much. i would use it to charge my 48 volt golf cart.

Is that issue fixed? With frizing charger I just got new 150/35 and after a week boom nothing happen from my array until reset

My 40A mppt does not have fan, Cause when you have actual mppt the efficiency of these are so high thus little heat. I always open them.

Hi, can you pls tell me some info? Since we will be charging the 51.2V 230ah 11.7KWh Wall&Floor-mounted LiFePO4 Battery (link bellow) with 3 x 480W solar panels ( Vmp = 37.10, lmp = 12.95A), we would like to have information on which Victron MPPT controller is suitable so that the battery will be charged properly (Operatin value charge of the battery is 43V - 58V). Does the Victron 150/45 match the charging voltage? Can such a battery be simultaneously charged from the panels and at the same time transmit energy to other consumers?

Hallo, wenn Sie den Wechselrichter aus der Wand-Elektrobox rausnehmen, können Sie dies besser kühlen, denke ich.

Dam Aussie postal service is so slow I thought you got that victron mppt back last week already.

Please let me know your using resistance value (ohm) and W for preventing spark?

Hey, I got a voltage drop from my Batterie to Victron solar charger of 0,05V without load or charging. Just turned the Victron on without solar panel connected. Now I set the all the settings in the victron 0,05V lower than before to compensate the voltage drop. What do yo think? Is that the right way, or is there a better solution?

@8:41 "This just, like to prevent "things" from happening." LOL ...

Why choose the 150/35. ? The 100/50 can handle more solor for about the same price

Wanna see some sparks fire works hehe 😎👍🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸

What size resistor did you recharge controller?

I didn't see you replacing the BMS yet. Do you still use the faulty one? Or the one they wanted to send you? Any plans on what to replace it with? I like the app you have so much more than the one of Daly.

The JNGE was doing 1000W, the Victroon 150W. I know that's not right. And simplify your life. Set charging to 14v all the time(fit to your setup of course). forget float, bulk, all that crap. No need with lifepo4.

Hey hey never mind my wife said we can do it ourselfs from our post office for $1.50 US so thanks anyway and keep up the good vids, mike

How many total watts can a Victron 150v 35 amp charge controller bring in 24v ? verses a 100v 50amp in 24v

I hope so!!! Great to see a new video!

That's it! No frog!! I am cancelling my subscription.. LOL. Just kidding. I think Victron has so much going for it, but for the price they need to be the best. I don't think they are there yet. The bluetooth is so bad too. I would rather spend more money to buy quality one time instead of cheap stuff many times for peace of mind, BUT. They have to deliver to charge such a premium price. Looking good -Bull frog! : )

Brother would I be able to run x2 160 watt panels on a victron 100/20 ?!?

epever can be connected to any voltage, but it will not change if correct voltage is not set. why cant victron do that?

Let me suggest that you read the manual for the 150/35 SmartSolar charge controller. You will discover that it says nothing about setting the system voltage prior to connection. Indeed, it is powered by the batteries, so if you had only a 48 volt battery bank, you would have been unable to set the battery voltage prior to connection. The manual also says nothing about using a pre-charge resistor. The proper way to do the connection is to turn off the main power switch, make the connections, and then turn the main power switch back on. You really should not be tinkering with the wiring while the main power switch is on.

What capacitor do you use ? I need to buy one. Thx

Can I use 48v with 24v batteries bank with that charger? Thank you :)

Can you pls tell me what is the dial setting for is located below the 3 lights

SCC . man! Learnin new terms all the time ;)

I really learn a lot from your videos. Especially how to prevent the big spark from happening when connecting the live wire over to the charge controller. Where can I buy that small capacitor that you use? And what specific model/type should I purchase? Danke!

What is the biggest cable size to connect the batteries, 10mm2?

Why dont u just buy a outback or a midnite classic

If it reset voltage automatically it make no sense to set it to different voltage. Why didn't get the 250/60 ? It is cheaper than two 150/35 and you can get 15kw with one controller.

Dose it tell ya to change the voltage in the book that came with it before ya hook it to 48volts

Hello from germany nice Viedeos do you make

Heat? Everything closed up in a cabinet.

Thanks Andy. I’ll bet your cheap controller is indeed PWM. Soooo many cheap controllers from China which are advertised as MPPT, are in fact PWM. Lies! I hope the new Victron behaves!

SCC...i believed thirst this is a new feature of solar charger...hahaha

Hmmm, two thumbs down again. Those two just can't stay away, can they? 😏

Hi Andy. I have sent you a couple of emails regarding charge controllers.

Hey Andy, is .3 really that big of a deal?

Now you have removed the cheap charge controller please remove the plastic screen covering from it, it's doing my OCD in, even now just thinking of it all half stuck on there.

On page 1 of the manual for the MPPT 150/35 it states "controller will automatically adjust itself to a 12V, 24V or a 48V system one time only. If different system voltage is required at a later stage, it must be changed manually" Again, its on the very first page of the manual. I really do wish that we would check ourselves before being critical of products and pointing fingers. Every time you point a finger there are three pointing back at you!

waiting to knows what happens....

Don't know about Victron but my Midnite has a process to factory reset so it can be connected to any approved voltage.
