Renogy 50A DC to DC Charger with MPPT Solar Input

[@madetoexplore]

This model is also approved to be installed inside an engine bay and it will trickle charge your starter battery when your house battery is full! Thanks for watching guys. Let me know what you think of this model in the comments below!

[@TheTechnoPilot]

That’s awesome! I’m wondering though if I could exclude alternator charging for now (future house battery install) and use the battery charging side to top up my deep cycle starter battery which will be the primary for now. Basically buy this now instead of the native Cascadia 4x4 VSS System’s MPPT controller. This would allow me to install this now with a long-term expansion into a dual battery build.

[@williambeck2997]

@@TheTechnoPilotyou can. Mine was hooked to my alternator only for a while, and now have both alternator and solar installed.

[@donjensen8335]

Great video. I bought one of these yesterday but now I am reading through all the comments, and I am worried about the fact that my 2022 Tundra has a smart alternator. I have a travel trailer with a solar system that can't keep up with my usage when we camp off grid for more than a few days. I use a noisy generator to charge my batteries. My buddy has a camper on the back of his older Tundra and uses the DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT to charge his batteries by idling his truck for a while. He can charge his batteries in less time and it's much quieter than my generator. I can't charge while driving because I have a trailer and don't want to run a second cable back to my trailer. The 7-pin connector limits the amps to about 5 I think. So I ordered 30 feet of 1AWG wire and plan to make a cable that I can connect to my charger when I want to charge my batteries while parked by idling my truck. After reading these comments about smart alternators, I think I will try to cancel my order on Monday and instead buy the cheaper DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT. Will that one work with a smart alternator? What is an ignition wire and how is it installed?

[@donjensen8335]

I found out that I can easily disable the smart part of my smart altenator right at the battery. I will do that. It may cost me a little gas mileage but I doubt if it is that much.

[@kennyhall7711]

Their is no need to disable it. I have the same dc-dc w/mppt 50a charger and a 2020 Chevy Silverado Trail Boss LT. It has a smart alternator and it works great with the renogy system. I regularly pull the max of 50 amps from it to charge up 3 house batteries. I have an electric cooler in my truck that never shuts off. Only gripe I have is with the mppt side. But that just might be user error

[@livebrando]

[@Jjeong_ji]

I'm concerned about the wire gauge, is there an option to swap the wires completely? Thank you!

[@madetoexplore]

@@Jjeong_ji not without disassembling the device. The wire gauge hasn’t been an issue at all for us! It’s a very short run. With that said, I wish they didn’t do the wire stubs and had regular ports.

[@PeterAlanJohnson]

@@madetoexplore I worried about this, before I realised that I am only going to be running short lengths to isolators, fuses etc.

[@BrandonBaecker]

As much as I hated running the cable to an ignition activated fuse, I feel like the old one will do better with smart alternators. I'm not sure yet if I can rely on a voltage cutoff to adequately maintain charge when the voltage changes constantly, but also shutoff appropriately when the engine is off. Now that I already have that cable ran, I'm not sure I want to go with one that can't detect when the engine is on or off.

[@madetoexplore]

Both are good models! It’s to bad they didn’t have the ignition wire on this one

[@billharrington172]

Hi David, I just watched your YT video about the new Renogy 50A DC-DC charger with MPPT (and the new circuitry that can be programmed to automatically prioritize alternator charging). I also downloaded your solar guide and I’m wondering if there is any update to the guide that includes this new DC-DC charger. Thanks, Bill

[@madetoexplore]

Hi Bill! Thanks for downloading the e guide. I’m unsure if I will be updating the guide as people seem to be having an issue with using this model with smart alternators. I’m hoping that Renogy will release an update to resolve this. In the meantime, the wiring will be the exact same except this model does not have a voltage sensor wire. That and bluetooth are essentially the only difference between the two models.

Thank you for the video! I have a question regarding the 'LowSolar current' shutdown setting and I cannot find the answer in the manual. Let's say the setting is at 5 amps, solar input is at 4 amps, and you stop the car engine. Will it start charging from solar at 4 amps?

[@madetoexplore]

Yes it will 👍

[@FreedomInACan]

Hey there, thanks for this video. We are also Renogy ambassadors and using this 50A DC to DC in our system as well. We primarily use it to charge our auxiliary battery in the back of our truck that runs our 12V fridge, and rarely plug in solar. However, we can switch the output to our trailer house batteries to charge while driving on those low sun days. We haven't seen the same amperage that you've displayed. We're only seeing a max of around 24A, which goes down and settles at 16 - 20A pretty quickly while idling. We noticed that in your video at 11:15 your starting battery is showing charging at 42A and house battery 38A. On our recent test, ours were 24A and 23.5A respectively. Renogy is telling us that we can only get 25A out of DC to DC (engine source only) but clearly that's not what you're getting. Any thoughts?

[@madetoexplore]

@@FreedomInACan on the previous model, I had to turn off my solar input and I believe it’s the same for this model. I have a switch that will shut down the solar input. Have you tried that?

[@FreedomInACan]

@@madetoexplore not with a switch, but I did set the parameters in the app to less than 10A, as you did in your video. We didn't actually have the solar plugged into it, so it shouldn't have detected any solar input. Thanks for the insight, appreciate your response.

[@FreedomInACan]

I'm starting to think that this is an issue with our smart alternator. We've been driving all day, no solar attached and only seeing 10 - 12A from the engine source. Do you know if you can has a smart alternator?

[@nmartin5551]

Hi! Appreciate the video! I’m helping a friend with a small house battery system on a van. Recommended this to her. As I contemplate the installation, I’m once again confronted with Fuse confusion. I know what they do and how important that is, but the sizing is where I struggle. She has the 40amp model. If I understand correctly, I’m thinking a 50-60amp fuse by the starter battery is needed. Right now there is no solar set up. Using the dc-dc feature by itself. Have a 2000 peak/1500 continuous inverter, using a 200 amp fuse. Am I tracking correctly, as far as you can tell?

[@madetoexplore]

@@nmartin5551 a common rule is 1.5x the max amps which I’m sure you’ve heard of. It’s also important that this number is below the max current of the wire gauge. I would go with the 60 amp fuse for the dc to dc charger and 200 amp for the inverter. You’re doing it right!

[@mschrank1]

Thanks so much for posting this review! I installed one of these units about 2 months ago, and have been frustrated by the lack of info online (and most of us know how (un)helpful Renogy support is). I've noticed that no matter my battery's SOC, the charger will only feed amps in either "Boost" or "Bulk" mode. I have a Lithium battery and have the app set to use the default settings for that type. Should I expect it to see a "float" or "absorption" mode once the battery is fully charged? Initially, my battery went into an overcharge protection mode once it was fully charged (it seems the charge controller kept trying to feed amps into the fully charged battery) but I haven't seen it do that lately.

[@madetoexplore]

That’s strange. You might be able to go into user mode and manually change the settings

[@mvemerson]

I wonder if it is possible to limit the alternator max charge current. I would use this product in a trailer and charge the trailer’s batteries while driving via solar and the 7-pin harness which is designed to carry 10 Amps. The combo limit could cause issues when solar goes to zero.

[@madetoexplore]

Unfortunately I think it’s only a combo limiter right now. I wish these were separate too! Not sure if they will be able to remotely update this in the future but that would be awesome if they could

[@ClarkyMalarky]

I got one months ago, seems to be a bit of lemon ? Even with some cut off at 10 amps, the unit only pulling 24-25 amps from alternator. Then Sometimes it’s 40-45 amp.

Does the temperature wire/guage actually let you turn off charging to lipo batteries that do not have low temperature protection built into them? The renogy website doesn't specifically say, or alludes to temperature only being used to manage charging profiles for lead acid. I don't want to charge my batteries with either solar or alternator if the temperatures get to low.

Again, well done! Quick question: you recommend locating that 60amp fuse (cube fuse?) at the beginning of the wire from the alternator.. Why?

Thanks for getting back to me - much appreciated. Here in the uk we don’t get that much sunshine so b2b charging is important supplement to solar. How did you get on with joining the units wires to those from the starter battery and aux battery as they are very different gauges.

If you have a smart alternator, I’d go with the older model because of the voltage sensor. People have been having issues with this one pulling 50 amps. Just when the engine is running

​@@madetoexplore , thanks for the reply! I have a dumb alternator so no problems there. Planning an Lithium upgrade for a sailboat where I'd like to use engine to top up the Lithium batteries quickly and maximize use of solar AND do all this automatically with as few components as possible. Boat has little space for solar panels and those are often in shade. I'd rarely get over 10A from panels. I was hoping that "LowSolar Current shutdown" would enable easy "automation" that "when engine running, take everything from alternator. If engine is not running, take every bit one can get from solar". If I interpret the manual correctly, in scenarios "When Solar-Generated Power is Adequate" and "When Solar-Generated Power is Slightly Inadequate" this "LowSolar Current" value is just ignored when charger selects it's operating mode. This would be perfect for me. i.e. what happens in scenario "Solar input voltage > 15V AND Solar output current < LowSolar Current Shuntdown" I'd like a confirmation about this behaviour from someone who's actually used the product, TIA :-)

All you get is little blips of charging when the alternator peaks its voltage, usually just during deceleration.

[@MakingStuffGoingPlaces]

@@madetoexplore I did see you go through that option in the video, however, that won't work as smart alternators often run a deficit of charge. It's not possible to distinguish between engine running and engine off purely by charge voltage. The only option here would be to set you sense voltage below the smart alternators threshold, but then the Renogy unit will continue to discharge the cars battery once the engine is switched off. Just going through winter with my current Renogy 50A unit (old version) and alternator charging is very important due to lack of sun...you can't risk it not detecting the engine running.

I have no idea! I haven’t had any issues with it. Renogy doesn’t have great customer service so I’m guessing that’s mostly the reason. The only issue I’ve heard with this model is it doesn’t work great with smart alternators because people don’t know how to adjust the settings properly.

smaller isnt better its gonna overheat like crazy...just like redarc does.

[@madetoexplore]

I have had this unit pulling 50 amps for several hours and have had zero issues with overheating. The fins are designed to dissipate heat and they do a very good job.

Not digging the short thin wires. I don't want to splice those wires. Yuck.

[@madetoexplore]

It actually wasn't that hard using this- amzn.to/45J6Y2U and i'm not having any issues with the smaller gauge. I've linked all the fuses and wire connectors in the description.

I went back and forth on this with Renogy customer support before purchasing. They assured me that the 10 AWG wires were adequate, and I went ahead and purchase one. I only ended up splicing the PV wire. The remaining connections were made using circuit breakers or fuses, so no butt splicing needed on those. I cut the small gauge Renogy wires as short as practicable to minimize voltage drop. It works great. The small wires don't get overly hot and the unit does what it promises.

@@mschrank1 awesome! Mines working great so far as well 👍

[@livebrando]

Have you seen the unit getting very hot like 170 degrees f?

[@madetoexplore]

@@livebrando not yet. I’ve had it up to about 77 so far and it’s been super hot over the weekend

Yeah 25v is a joke.

[@madetoexplore]

@@faffybubs9099 it is! 50v is much better

[@faffybubs9099]

@@madetoexplore they need to keep up every one in Aus running house panel now they cheap and run 50v or more

I placed an order with your code and it worked a few weeks ago. Trying to place another order today and it looks like madetotravel is no longer valid. :( just fyi in case you don’t know

[@madetoexplore]

@@maryanntimethanks for letting me know! I just checked online and it seems to be working on the US and Canada website. Which website are you using?

[@maryanntime]

@@madetoexplore renogy official website US. I tried another influencer code to see if it was just my account and it worked for theirs. I haven’t placed it yet, so I was thinking it was just yours with an issue or if I can only use yours once. I can take a screenshot to show you.

[@maryanntime]

@@madetoexplore actually I took the time to read the error message for the screenshot and it does say “The coupon code you entered has reached usage limit so it can't be used.” Grrr this annoys me that I can only support the influencer once. Renogy needs to do better on partners and client customer service.

[@madetoexplore]

@@maryanntime to be honest, I had no idea about this! I’ll reach out to Renogy. We appreciate the support! 😄

[@maryanntime]

@ looks like they fixed it! Placing a smaller order now. Happy to support y’all.
