Bluetti EB3A Charging Methods! Connect external 12v battery and charge with solar at the same time!

Рет қаралды 24,173

Күн бұрын

The Bluetti EB3A is a small portable unit with great potential, but it has limited battery capacity. In this video I will show you some ways on how to keep it topped off with an external battery and be able to charge that same battery at the same time using UGREEN foldable solar panels! I even use a 12v to 24v boost converter to give it more power! The secret is to use XT60 connectors to make all the connections the same!
This video was so much fun to make! I hope you like it!

I’m a 60 year old woman, trying to power a caravan shower and fridge, went to Jaycar, they told me I couldn’t do what I wanted with the Bluetti eb3a, but guess what , thanks to you I CAN, using different connectors, but the principle is the same, . The DC to DC convertor is the key, thank you. I have had to watch you video heaps of times but I think I’ve got it.🎉

I’m a retired EE and I wanted to say that you did a really great job here! I have been using XT 60s for many years for RC hobby use and now power stations. The 12->24 V boost converter is a great way to charge power banks more rapidly from a 12 V battery. And you can double the capacity of an EB3A or EB70S with a $100 50AH battery, which is much cheaper than buying a larger power station.

Thank you great video Last year things got really bad around the Branson Missouri area and we lost power twice during some very severe storms. So this is all new to me and I decided to get a small 40 watt solar panel thinking maybe I can bug out with it. Now my thinking is staying put and decided to get the Bluetti EB3A today so now it's a learning curve I hope that I can use this 40 watt to charge it and at least 8 hours or I might just break the bank and get me a larger solar panel what I'm going to have to figure out all of this wiring stuff that's for sure . The solar panel is made by Flex solar and has a USB and c and I think a 12-volt Barrel plug.

Your videos are really helpful. This weekend I've watched at least a dozen of them. I'm very confused about your grid tie inverter connected to your batteries, instead of to the solar panels and then to your house outlet. That's how I've used them in the past. I heard your explanation but still confused. Please consider making a video from beginning to end about why you do it this way, advantages, disadvantages, and is this way better than going straight to your house outlet? I know you want to use your batteries and keep them from sitting on float, thereby wasting a lot of power. Is that the only reason? Anyway, I'm confused and would love to see a simple walk-thru of this part of your system. Thanks. Jim

@OffGridBasement 11 ай бұрын

You're correct. I mainly used the grid tie as an energy dump for when my battery was getting full. I used the smart plug because then I could control when the grid tie inverter would actually turn on. It doesn't work if it doesn't sense AC power. I could make a video and just connect it to a single 24v battery to demonstrate how it all works. I hope this was helpful. Thanks for the comment.

But the jackery charges way to slow so I am thinking about picking up the EB3A :') this will work, but be hard to solar charge the 36v I have to use a 120v brick.

Thank you so much for your videos. Could you model and shoot a video at what minimum power from the solar panel starts charging at the pv port? And do I need to observe the current limit of 8.5A when buying a non-original panel or will Eb3a itself not take any more? Your authoritative opinion is very important to me. We are preparing for blackouts in Ukraine, I purchased an Eb3a and I don’t know how to select the maximum panel to work with at least a low charging current in a cloudy winter.

@OffGridBasement 9 ай бұрын

The EB3A will limit the amps. It's max is 8.5A. the thing you need to keep in range is the voltage. Don't go over the max voltage or it could damage the unit. Any panels you connect to it will probably need to be connected in parallel and not in series. Hope this helps. Thanks for the comment and take care.

@pBinx-bd8xg 10 ай бұрын

very good explanation. One question; when disconnected from solar will it use the external battery power first then the internal battery power?

@OffGridBasement 10 ай бұрын

Not in a true pass thru sense. It will keep the internal charged to 100%, but I believe the unit always uses the internal first and whatever is plugged into the charge port just charges the internal battery. So the external will be depleted first, then the internal will start to deplete. I hope that answers your question. Thanks for the comment.

Hi, Really liked the video. I got a lot of insight on the EB3A. Doesn't the Eb3A solar input have a 8.5A input limit? This buck converter says 10A. Sorry I don't know electronics too well. Also how many amps are coming from the solar panel and the battery charging together? Is it less than 8.5A. I have a 58.8V 2.55A solar panel it's much more portable than full size panels @12"x8" folded. I'd like to use it but It would take a step down converter and getting the right voltage and amps for the EB3A from it isn't automatic and would cause a blow out if I got it wrong. I also have a mini 12v 20Ah battery I can charge from too. I'm wanting a sustainable portable power solution for when I go canoeing & camping.

@OffGridBasement 11 ай бұрын

The EB3A input will only accept 8.5 max. So I don't believe you need to worry about the amps. I would get a small 20A solar charger controller to connect the solar panel to the battery. That would convert it to the correct voltage and amperage. Then you could connect the battery to the EB3A at the same time. Hope this helps. Thanks for the comment.

Thanks for the good video. The question is how can I charge an extra battery without buying a new mppt controller. My point is I have an ecoflow delta 2 it has a solar input of 600w. And I'm a camper van with panels on the roof. As an additional battery, I have thought of buying an additional 100Ah battery. When I borrow ecoflow with the sun. And then from the dc output directly add a 12v dc to 14v dc converter to the battery. Then I will have a much simpler system. And when the ecoflow runs out, add back from the battery with a 12v to 24v converter directly from the battery to the ecoflow.

Buying a 24v 150ah LifePo4 battery $400: No need for step-up, and EB3A can handled the 24v. Any issues with the 150ah? 2. Connecting existing panels (MC4) to a Battery controller (assuming I can make a connector for this). Is the 20amp controller enough? 3. Connect the battery to the EB3A and will get something crazy like 3,600Wh Few questions: 1. Would you not need MPS? To manage the LifePo4 battery? 2. How and where to connect the fuses? 3. Wonder if it would be possible to connect two batteries down the road? Thanks so much for this video.. Life changing at best (emergency) wallet saving at worst.. ;)

Glad to hear the video helped. 150ah is no problem. Wire any additional batteries in parallel. If possible, wire a fuse on the positive side of the wire going from the battery to the EB3A.

Great video, in showing how a few extra items can improve charging of a small system. Those 100w solar panels look a bit small.. Have you seen 100w from those on a sunny day?

@OffGridBasement 11 ай бұрын

I've only used them on partly cloudy days. I've noticed when the sun comes out from a cloudy it shoots up to above 100w then drops to around 90w. The panels were also pretty warm. Sorry I'm not helping much.

@technishn 11 ай бұрын

If they get above 100w great. They might throttle back as they get warm. The lightweight ones may have less thermal mass than a fixed frame one, so increase temperature quicker? Lithium batteries are still expensive here still in NZ, so still playing with AGM here.

Does this setup only work on sunny days and with LFP batteries with an integrated BMS? Because the BMS will cut off the load when the battery voltage drops under a specified value? Does it also work with an AGM battery without an undervoltage protection? Or will the bluetti cut off the input if it was below 12v?

Nice video I think the idea of a battery charging another battery (power station) isn’t genius enough because you’re depleting the cycle counts of the two batteries in a redundant move. The best approach should be connecting an inverter into the extended battery and into ac input of Eb3a this will allow UPS of Eb3a to draw directly from the extended battery and later on from Bluetti itself this will maximize the usage of both batteries instead of depleting one to charge to other. I hope you would make a video showing and proving this idea
