No, solar and AC, and various other mixes of inputs will NOT work to sum the inputs. The controller picks one. The 1500X manual explains that, and explains how the controller picks which one it will use. You’re also doing other things that are explained in the manuals of those products. It seriously is an excellent resource. When you plug in from the top, it switches to using that. You need to be a heck of a LOT more patient trying things-in particular, changing inputs. It takes up to several minutes for the controller to adjust and adapt to input changes. You mentioned that you “found out” some things. Most of those are explained in the manual.

*fries charge controller* "I wonder why it doesn't work?" *charge controller waits for him to give up, and resets* "I'm going to return it."

After much researching - all charging must be combined and enter thru the Anderson port. No longer can have multiple entry ports at the same time. 600 watts incoming max for the 3000x. Thanks for all your post about this, helped me start to understand.

Glad I found your video. I had similar issues with the 1500x after upgrading from a 1000. The AC charging port on the front did not respond after a couple of attempts and waiting for several minutes (no solar connected during this test). After the 3rd try it started working… ok, I can live with that. My biggest issue is from this test: connected a Dometic CX35 cooler and after 24 hrs with the cooler being OFF, the 1500x dropped 3%. Same test with the 1000 resulted in 0% loss… that I cannot live with. The 1500x shows an output of 0.1amps while the 1000 shows 0, both cases with the Dometic OFF. Will contact GoalZero for answers but it is pointing to a return item and reviving the 1000.

I just got 1500x and straight swapped it with my 1000 lithium, you have to use the 1000 lithium's 115v charger however, as stated in literature, and I also had the mppt controller on the 1000 and moved it over as well and it worked just as it did before(no buzzing as I read somewhere on older mppt's). Good to see these struggles online, and others who've replied similar to myself now the same solution works. Sure I only get the 60w 115v input when on shore power but it does sum with the solar input when you have both feeds. Hope that helps. I got what I wanted, same size package but an extra 45 amp hours. With the 360w of the 3 panels on my trailer I can run domestic cfx-75 on freezer both sides in summer temps and catch up every day no prob, the freezer side of the domestic is the big power draw. In winter ice fishing both sides on fridge it's nothing. All the other electrical demands and things we charge, lights etc. are also nothing. Will see how the new Webasto 2kw heater will be for draw but no worries based on specs now as that will primarily run winter when the fridge doesn't work very hard anyway.

You're weird, not the system ... you really need to know how the internal system works.

I had a GZ 1400 in my camper van and was able to stack multiple charge sources without an issue. This was great since I could get power from solar, the 12v outlet on the van while driving, and/or shore power at the campground. Never an issue. Now with my new 1500x I have the same complaint as you. Talking with GZ the work around they recommended is adding the GZ MPPT solar optimization controller so can charge from 2 sources independently. I had one left over from when had the 1400 so installed it. I can now charge from multiple sources at the same time again and the watts are additive. HOWEVER whenever charging using the add on MPPT I get an annoying buzzing sound coming from the MPPT. Sooooo - calling GZ again.

I suspect there is switching logic that prevents overcharging for protection.

I give you marks for having the courage to share openly.

The port your pluging the Anderson in is for input for charging not for running things. Plug it into the 12v area and it should work

I have two goal zero 1000 and 1400 and switch to my Arkpak 730 and bought an Ecoflow because of the problems with the goal zero. Ecoflow and bluetti are now top dogs in rechargeable battery packs.

Goal zero is terrible I regret buying my 1400. Overpriced and every issue with these batteries just causes you to purchase more of their little accessories. I wanted a simple plug and play but would have been better off learning and building my own system for all the money and trouble I went through with the company

It was so good , that I ve seen your videos. We are van club at germany and thought we buy 82 goal zero 1500x together for a good price. But now we will not do this of course. Even the Tussy from Goal Zero hasn`t had any idea of whats happening and no help , like a direct technical supporter on phone. I will inform over our network at europe immediately around 1100 Van Fans . It is impossible that the 1500x can not charge parallel and has such tremendous problems like ya ve shown. Thanks so fine :-)

the Goal Zero MPPT Module (the one that is $100) allows you to take multiple inputs in an additive fashion, like the old PWM method. Just a FYI

Thank You for posting I was very close to buying one of these. I am not anymore. I agree with another comment, for what it costs it should work like a gem.

For what that thing costs it should work flawlessly every time.

good to hear you can can return to REI I might have to try that my 1500x has been a little wanky compared to my old 500

Read the manual ! It says that you cannot charge both by solar and wall electricity at the same time !

17W solar is much to weak, the unit is balancing to charge or not charge. Mobile phone chargers can charge with more then 17W and the solar would take a couple of days to charge the goalzero.

I have a 1500X too. The first one had problems with both USB Ports. After exchange the USB where working and the solar main connector was working well. But if I used the main and the small (circle connector) together I had first maximum watts (260W) of charging and after a vew seconds around half watts (105W) and then zero. After some seconds maximum Watts again and then half and so on. Both ports had exact the same solar panel 180W and 35V. Firmware was v1.21. Today I made an upgrade to v1.30 - now I have all problems you had - the main solar port isn't working anymore correct.

You are lucky that it shows 17w input , the normal is that it does not show under 20 w input when sun charging ! You cannot plug in solar and wall charger at the same time unless the sun went down . If you have a programmable stopwatch you can set it to go on at 23:59 and off at 6:00 . Plug in both cables in permanent at the same time and then the whole system is automatic ! Then the wall will charge the battery at night and the sun will charge the battery in the daytime ! What more do you expect ? There will always be something to draw from it that way !

Was going to say maybe it can't dual charger from 2 different power sources at the same time. Maybe it picks one over the other when your trying to charge it from 2 different power sources. You would figure for that price it would be different but it is what it is

Solar or wall charge...... units telling you to PICK ONE!

We’ve have been traveling full time for about 15 months now and during that time we have gone through 3 yetis. The first one was a yeti 1000, then yeti 1400 and finally the 1500X. We’ve only ran a dometic fridge and used it to charge phones or laptops. The 1500X issues now for us is the AC outlet stopped working. Even after doing factory resets. It’s so crazy to me that these products are so fragile. I went as far as to use styrofoam padding on the bottom and have it secured down with straps. Still broke. I would not recommend these for full time traveling since when it does break you’ll be screwed, unless you want to keep driving to salt lake to get a replacement.

I don't get the purpose of this video.. You didn't read the manual and you called customer service telling you the things the manual said.. Or maybe that was the purpose? To get people to read the manual?

We have one, after a lot of research since this is using an MPPT controller vs the old PWM charge controller. So do we have a trade-off between more efficient charging on the solar and the convenience of charging 120 and the solar at the same time? Maybe the older PWM controller was able to handle stepping the voltages?

Thank you for posting. I a new 1500X too.

The supervisor is full of crap. Sure, you can’t use AC and solar at the same time with these controllers. But the main problem is that from just a solar panel, 0-20W is *not ok* on a clear day. Are you returning all GZ equipment? I kinda want to.

You cant charge from 120 and solar at the same time ones dc and ones ac cant do both

It does charge and send power under 32f watch many videos on YT doing just that in real world situations. Also the goal Zero works better in colder temps in a insulated cooler and on its side ( videos on that too)

Why did you stop using the 1250? Im considering picking one up.

Search trying to think of the difference between the 2 goal zero's in your new one has an MPPT controller. I wonder if that's why you are not able to use solar plus the wall outlet charger? I do have a work around suggestion though. I have a 60 USB C charger plugged up to the front of the goal 0 which will add to solar . It's only 60 watts but It might be a solution for you.

When the sun is to low on the horizon you cannot have the minimum power necessary to charge.

Read thecowners manual. duh!!!!

It seems like more and more people are very disappointed with GZ products lately. It's definitely not the same company of yesteryears. To bad, it was such a great product once upon a time. Charges way to slowly.

I’m hoping for the best and getting the 6000x because if for some reason it’s not working like your has I know where the are and I can drive up to there door if I have problems with it

you have a shortage wattage Anderson connection

Curious about the solar panels you have plugged in. How many volts are actually coming through the Anderson plugs, and how many watts are your solar panels? I have the Yeti 1000 Lithium for the past 3 years. It will not accept more than 360W total coming in. If I try and push it above that, it will go to zero and then bounce back up and then down to zero again. I wonder if the voltage is somehow exceeding the limits of the box. You mentioned charging in the cold... So during the time of your testing December, it's probably cold where you are. Solar panels can actually exceed their rated voltage when it's really cold outside. So that leads me to believe that there is some excess voltage going in. Maybe. 😁 On my channel I show how to connect the Goal Zero to the alternator of my Sprinter using a Victron Orion DC-DC charger to charge my Yeti while I drive. Works awesome. From my tests, if I exceed the 360w coming in from the Victron by also trying to charge with the power brick, my Yeti will go down to 0 then jump up again, then go back to 0.

I had my Goal Zero 500X for less than 3 months and it stopped working. Goal Zero won’t honor their warranty either. Several years ago, they made good products but has really dropped in quality. I’ll never buy another Goal Zero product again.

Man, for the price, I was expecting this to be more superior than others.

Dude read your manual. Your problems are operator error.

Solar eclipse came sneaking up. Me too

kzfaq.info/get/bejne/qNeIpsZ1m5-2poE.html Check out Will’s video, he shows how to use a third party charge controller and get way better input than goal zero’s PWM or MPPT.

I bought a Yeti 1400 and it started screaming and reseting. They sent me a second one same issues. They sent me a 1500x because the 1400 was no more. My 1500x sucks like yours and they never sent shipping to get the 1400. They never sent me credit for a Yeti Link I returned. Now I have a crappy 1400 and crappy 1500x and can't get a reply from support. They suck as do their generators.

Goal Zero 1250 and 1500 are not the same ! on goal zero 1500 you don't get a read on the display under 20w !

Idk why people are still waisting money on Goal Zero's crap.

*****please go back to a video you made back in march 2020 and help me with one question*** (video )== ***how to use old iMac 2009-2014 as a secondary monitor**

Did you read the manual?

Would your original 1500x charge on AC power? I’m having similar issues but mine will charge on AC power just not with my solar.

guessing software issue after about 1 minute.

wow they started giving you BS about the weather!!! If they dont know why dont they just say so

The Battery must be charged at all Times.

no my 1500x cant charge from wall and solar at same time either

Not ideal, but you could consider/try a solution like this and see if that helps: kzfaq.info/get/bejne/qNeIpsZ1m5-2poE.html

So I tried the car charger and the wall charger at the same time and it didn't work. I could add usbc charging to either though. Next Im going to try multiple car chargers

here a power station with much more power, better technolgy and even cheaper >>> POWEROAK portable Powerstation AC200P

Well that sucks! I can't believe they pull weird stuff like that... only one input that's unacceptable. I have not tried both soalr + AC on my 3000x yet, I use the tank module, it charge 500-750w while driving witch is awesome. The X has mppt and accept up to 50v witch definitely helps with big solar panels depending on your needs.

Any update?

U should probably purchase 1 of those cheap harbor freight generators that use gas and make sure u use a harbor freight coupon get 10% off

Why did you wait so long ? You might just have a bad one. It’s not an excuse but it do happen

this ridiculous but it doesn't work this scenario on this model. Yeti always take charging from inlet that has a higher voltage, even it has a none wattage. As can you see this is another nonsens in generation X. Next fu...ed thing is that battery is charge to full and than discharge to for example to 95% then charge, discharge, charge forever, even if you have power delivery in to inlet. I wait for next gen of yeti.

Lol
