First Battery Charge. I needed to do this! 

Planning something similar.... these videos are helping me solidify in my head what I already understand. Thanks!

Happy to see you making very good progress.

There is nothing like the feeling of making your own power, especially when you put in all the work, and when it's clean power it's even better!!

My inverter arrived this morning. Completely unannounced, days before it's due. It's HUGE.

...Your green friend loves the heat from the inverter. Ok, have fun!

Off topic.... but MAN seeing you walking around in shorts and nice sunny weather, im just picturing a hammoc, a cold beer relaxing! Im feeling envious :P Here in sweden -20c :)

im happy to see this project has come so far, good job

Well done.

That moment you're getting solar power for the first time,i wouldn't wait too,fan from Kenya

Great job Andy, nice to see its working but I would put the power lead for the shunt on the battery so you can tjek the battery without turning the box on every time

Great video, Thank you, I enjoy watching your progress

I'm happy for you

Ha Ha!! Great Day Andy!! Nice job : ) You need to add some panels now that you are addicted! LOL

Awesome! Congratulations on your project. Tell froggy to jump in a lake.

nice, now with secondary switch.

Loved it again. 😊👍

Nice work Andy

Great work

Congratulations on commissioning the charging side. Very neat and well thought out.

Herzlichen Glückwunsch vom verschneiten Niederrhein. Aktuell sonnig und minus Ar***kalt irgendwas. Meine 8.875 kWp PV brennt gerade 8.8 kW in die Batterie und ins Auto. Ich kann also Deine Begeisterung total nachvollziehen.

Nice work ☀️

I heard a large Bang!!!!!!!

Always nice to see solar work it is truly amazing. Frog is inspecting your heat sink.

Excellent fascinating videos. Will be moving from gel to lithium chemistry on my home off grid project and also I'm happy to see victron smart products in use. I'm following from Kenya. Looking forward to the next video. :)

Congratulations!

I'm excited for you. Can't wait to start my build.

I don't blame you, I wouldn't have been able to wait either. Looks Good!

Lift off! 🚀 this is way better than watching Space X SN9 not lifting off 👍

First test no spark ... that's good :) But I still would put a thin plastic sheet between the cells.

That moment of suspense when you close the solar circuit and nothing appears on the phone until the mppt starts tracking then the watts start to climb :)

well done

I'm happy for you. mate!

Congratulations on the charging test, well done, great job.

Awesome job! I love it! I like the Victron charge controller too - I might have to get one and replace my Epever. Learning a lot from your videos! Thank you!

Brilliant work Andy. I was sharing your excitement. Who needs a woman when you have solar 😂😂😂. Keep the great videos coming mate.🇬🇧🇯🇲

I got really excited for you man, I've got a smile on my face from ear to ear. I'm getting ready to wire up the panels to my system myself. I just finished up a test pulling 1500 watts for the last 3.5 hours with a heat gun thru my inverter. Brought them down to 2.8v per cell. (8s 24v Lifepo4 CALB). Everything went smooth. Tomorrow morning I'll put the multimeter to them to see how they balanced overnight then the next time that they are charged I'm hoping it'll be with the solar panels. We're getting a major snowstorm over the next several days here in New England but Im hoping to be testing out my panels for the first time in the upcoming week. Congratulations on a great job and thanks for sharing your frequent updates with us.

That wedding ring!! Do me a favor!!

Great!!!! You did it.

I’ve watched most of your videos and you have done a great job

I would not been able to wait either

Mariachi celebration!

I know you couldn't wait It's a new toy for us kids.

Great videos Andy. I have really enjoyed watching the progress on your battery build. I use the Victron smart shunt in my RV and I think you will be disappointed in hooking it up to the output side of your switch. The shunt is able to track history of the battery pack which you will lose every time the power is turned off. Also the state of charge must be reset to 100% each time you turn on power to the shunt. If it is powered all the time then your state of charge and history will remain.

congratulations on a job well done **🐸🐸**

Great vid ! I need the version of the app for your bms, the one they linked me dosen't show everything on the screen

ya....hooooooooooooooooooooooooooooooooooooo! Great Job!

Congratulations. BTW you could have easily got the CC cables through the hole if you had removed the cables from the CC terminals and push it through, from inside the battery cabinet. I hope I can build my pack soon. I bought 16x 105AH cells from AE in 2019 and I got duped. After that I lost hope. But the cells are much cheaper and widely available now. Anyways, thanks.

So you picked the fruits of your good work. Nice to see. Will you stay with the ANL-fuse?

Another fantastic video. Just wondering if you are going to connect you inverter to the P minus of the shunt??

You have done a beautiful job great work. So are you going to mount the battery into the Model-3 ?

good job!! have u consider the active balancer besides the bms? i watch people using it to balance them faster ( pardon my english hahaha not very good )

about that nasty switch cover - it has a problem with the fuse cover, I think you will need to move the fuse a little bit.

Where can I buy the exact BMS you used? Waiting for my 8s 100Ah LifePO4 and seems that your BMS fits what I need. BTW, found your channel and I'm a fan!

Congrats! I love the feeling of getting these things working after so much planning, building, and smashing through the little problems that inevitably come up along the way. Now that your 660W garage sized system is coming online, the next thing you will want is more power for the house? Always happens with us guys. :) That 660W will just be able run my desktop PC, home theater amplifier, and a large LCD. But not in combination with other common home automatic appliances like a fridge and an attic fan -- which I found runs at 400W itself! So what would be your plan for a larger "house sized" 2000W or even 6000W solar setup? I'd like to see a 6000W solar array setup using 48V system! You'll be needing some long runs of 00-gauge wire to carry the 125A of deadly current. Or maybe split up 6000W across three 2000W GTIL2 inverters that can be "stacked" in synchronized AC parallel mode. I would have to check the quality of AC waveform output from those Chinese made inverters because quality AC output from DC is not trivial. Also that 2000W at 48V still pretty "hot" at nearly 42A current will need three of them.

Can you send me the link of the box? Great vide BTW

Does the victron charge controller have a dump load function? Would be nice to heat some water with a DC heating element when the battery bank is full. Would be nice for a hot tub eh?

Another great video Andy..😊👍 I do have a question about the Victron controller. When the unit shuts down the voltage because the battery is full, can you program the 'load' terminals to divert the solar power that you can still produce (but now not needed to charge the battery) to a 12v heater element in a hot water tank..?? 🤔

Good job and what inverter are we powering the house and garage with 😎👍🇺🇸

Any new updates on the BMS? Thanks.

After seeing all the monitoring devices working and the whole system working, if that is my system, I will remove the shunt, the battery switch and also change to a BMS without the Bluetooth as they are the weak link on the system causing unwanted load. My primary goal is improving system efficiency. Ever wonder why the solar charge controller does not have a display but only simple LED as indicators? The answer is to maximize efficiency. But without those monitoring devices the video can be boring so it is a must thing to do. :) The frog is charging up, warming up, that frog understand very well how to be energy efficient. :)

Eureka! The system is charging great moment and everything worked. Now the inverter to do and you have the mains power and total power independence in your garage. It brought back some great memories of switching my system on for the first time three years ago. Because I am UK based and using lead/acid deep cycle batteries (lithium batteries were just to expensive back then) I have to use a mains charger on cheap night time electricity for a couple of months in the winter. Do you plan to do anything similar for your system as a backup charging strategy? After watching your video I think I will be upgrading to a lithium based battery so that I can cycle deeper and without damage.

Yes, now you need a GTIL and connect it at night so all your energy consuntion will come from the Frogie box.

Did you set charge controllerto battery profile 7 LifePo4?

Hi Andy, ich finde Deine DIY-Batterie super und die Videos bzw. die dazu gehörende Website auch. Gibt es so was wie einen Schaltpllan und eine Stückliste für die komplette Batterie in der schwarzen Box? Ich plane das gleiche für Paraguay, nur ohne PV, als Stromspeicher für ne Ersatzstromlösung. In PY fällt öfter der Strom aus, kostet aber dafür nur 0,04-0,06 € pro kWh. PV rechnet sich daher nicht. Ein Speicher ist aber notwendig. Die Box kommt dann an drei Victron MultiPlus II (=dreiphasig) als Verbindung zum Hausanschluß. Das ganze wird allerding in DE konfiguriert und zusammen gebaut und als Modul im Umzugs-Container verschifft. Beste Grüße und mach weiter so, KaPe

jan from Texas. great work and the excitement spills over. u would be a great actor in HOLLYWOOD. I do have 2 questions. i am trying to buy the same battery u have from Alibaba but none of the 4 credit cards i have would work. Alibaba told me i can be per-approved by taking a picture of my credit cared and my passport which i did (not to smart). still no luck. how did u pay, wire transfer? the other question was, the BMS has a blue-tooth connected to ur fon in order to see all the cells. is there another permament way to see what the battery is doing without the fon? again great work.

I just got my 280 ah lifepo4 battery up and running and im testing to see how long I can power my gaming pc build before it dies judging by how i use my computer it can last 20 hours straight Currently 4 hours in and Ive only used 50 ah

At 5:00 it looks like there might not be enough room to remove that fuse. Have you checked you can get that fuse in and out in case you ever need to replace it?

Can't find the BMS online

Putting the voltage sense on the output side of the isolator is a bad idea. When the shunt loses power, the CE and % charge data will be lost. That sense wire should be connected as close to the battery positive as possible.

when connected 150.35 i did the mistake to instal last the possitive terminal forgeting close both battery breakers... spark was quiet big .. still think until today i burnt something... !!!! never again!!!!

Normally red wire to positive. In your rush don't make a mistake?

On my 24 volt lithium battery system what gauge wire should I use that will run from the solar panels to the 80amp charge controller?

cooked frog ? :O lol

I don't really understand your charging regime. Have I missed a video about that? Us I understand you with from bulk to absorption @ 3.35VPC, then to float @ 3.3125VPC. Balancing for every cell @ 3.36VPC (so any high cell will be balanced). Does this charge your cells properly? I understand that anything under 3.4VPC is not considered charging. Reason I am interested is, that I have a propellor charger on my boat that allows me to change the voltages BUT I can only have an absorption duration. Because I won't know the SOC when I start sailing it would be a waste not to use the full (40A) capacity of the propellor but I don't want to overcharge either. Conundrum!

Bro isn't the voltage lower than max ?????

Hi I was just wondering where was Andy born, can't figure out his accent.
