Adding / Installing a new Pylontech us3000c us5000 us2000c battery to a existing setup/stack 

Just getting ready to go up in the loft after lifting a US5000 into there and checking that I'm up to speed with the connection. Found your video so reassuring to watch. Will see about posting a video of the lift by two OBE's

Brilliant, thanks for this, most useful and much appreciated. Cheers!

Are you sure you don’t need to balance the charges before connecting to the inverter?

Thank you for the concise explanation!

Thanks for sharing 🙏

Thank you so much for this, have had system in place for 1 year, now going to expand storage, very informative and understandable video, thanks again - Frankie

Hello🥲 i have a problem with the same kind of batteries, i do as the guide says and after i turn the bateries on, the master battery turns on the red led of "ALM" and it doesn't get solves... Any idea of how to fix? Im new around, thanks in advance

Thanks for sharing, i am still confused about if diying a battery with cells bms etc or buying a prebuilt like this.

Hi and many thanks for the video - I have a stack of seven 2000's to which I need to add a 5000. I understand that the 5000 has to become the new master - the question is, how is the new stack balanced when there is a mixture? I was told that I had to first fully charge my stack of seven 2000's and then separately charge my 5000 before adding the 5000 to the stack. This sounds awfully laborious and long winded so is there a neater, simpler way please?

Excellent video, it really helped a lot, just one quick question, is the positive from the inverter always connected to the master battery...I have four batteries which all seem to be fine but the black negative is connected to the master.

Thank you for the video. I have 4 US2000C and I'm thinking about ading a US3000C or a US5000C.

Yo pondría 2 cables positivo y 2 negativos...así se te calentarán menos...

Very interesting video, thank you, I would like to ask a question; if the solar panels fail to charge the batteries, could they be charged with a charger connected to a generator set ??and how??

Thanks for this. Do you know if you can mix different capacity pylontech batteries? I currently have 2 x USC2000 batteries and want to add an additional 2 x US5000 to the system to triple my storage capacity from my Solar Edge inverter!

I have 3 batteries. While I'm working off batteries, just 2 of them are flashing with all green lights. The one that is in the middle is just flushing "run" only. I do think that power is drained from 2 batteries that Victron is connected to with plus and minus. Is that a problem?

When and how do you switch the inverter on and off?

Can only one of these batteries alone work on a 5kva inventor? If yes, how do you connect it

After adding 2 new US3000c batteries to me my existing 3, do I need to change any settings on the inverter to ensure I am charging to the max 17.75kw capacity?

Very good explained! At any point in time your system is designed such, that all these batteries are discharged with a constant rate not exceeding 100 A, right?

Hello Sir, I got the US3000C batteries (two) and unfortunately I connected them to an inverter that seems to be incompatible with the system as a result the batteries have gone into safety(sleep)mode and I don't know how to go about it from there, please assist me.

hi.. thanks for the time you spend on the videos for us.. if i want to raise my Battery capacity can i use a 3000 or 5000 in an 2000 system or must i stay with 2000???

The new master battery has been fitted and all wired up but when I turn on the batterys all the LEDs on the new battery stay on have you any idea wy

Thanks for the video. One question if I can? Do you need to let the inverter know you now have more capacity? I seem to remember this was set at the time with my original set up a few years ago. I’m about to add 2 new batteries to my stack.

Awesome vid mate exactly what I need ... Question...I have 3 x 2000 batteries at present and am going to add another 3000 is it neccessary for the 3000 to be the master?.... also my 3 have been stacked ontop of one another at install same question,... is it neccessary for the 3000 to be at the bottom? as it is the heaviest at 32kg?

Hi I was wondering if you help. I have a Goodwe ES 4.6 inverter with 2 x UP5000 (pylontech) batteries. Can you please advise what the DIP switch setting should be? Does it matter? My installer used very specific switch settings but I can't find any reference for it. I am asking because I want to expand my battery pack to 3 units. Please advise.

Great system, however consider that the link cables between batteries and especially important, the long Pylontech Inverter cables must not exceed a constant 100A, due to both connector and cable ratings. They can briefly go up to 125A for a short time. I am not an electrician, but have read quite a lot about high current DC storage designs. Now my concern, (not sure if I could see this correctly) you appear to have a large system connected in parallel with only a single cable providing battery power to inverter. That means you can only draw 100A / 7(number of batteries) = 18.29A per battery before you exceed the cable rating. That is just 978W per battery. Your system potentially exceeds that easily the way it is connected, unless you have fuses protecting that cable with a 100-125A fuse, and a limit on the inverter/charger. To solve this, either use a small inverter maximum 100A, or a better solution, buy extra Pylontech long cables and wire in parallel to a high current bus bars for both live and neutral, then come off that with a higher rated cable towards fused inverter cables. Theoretically then you can go right up to the full massive rating that these batteries can supply. To enhance, try to ensure the batteries are fused before they reach the busbar also. That can be achieved with modified Victron Lynx Power In modules that are rated up to 1000A. RU-vid has some good videos how to add fuses. Please check your inverter and batteries aren't exceeding all those cables.

thanks for the video, i have a question I have 2 us 3000 in parallel linked up to my solar inverter, I am about to add a wind turbine with a separate charge controller to my system but cant figure out how to connect both the solar and wind cables to the battery as there is only one connector for positive and negative, any suggestions? thanks

I just added a 3rd us3000c battery in my stack, all 3 are the same model. However, when balancing them, 2 seem to get balanced and go on standby while the third keeps all lights turned on. No blinking. I waited for approx 3 hours already and it remained like that. Would you know what could be causing it or if can just go ahead and plug everything in to the inverter?

So, what are the dips made for ?!

I currently have a single stack of seven 2000's which the installer set up. In studying the PylonTech installation manual, it says not to stack them directly one upon another and even when using their super-expensive brackets, it says a maximum of four! Have you ever heard if or experienced. any problem with stacking?

Hi,you can tel me please, when we must change the position of the four ADD Switches,thanks.

Do they have to be earthed? I have 2 no. 3000 and they're not earthed and Im having problems ballancing them, thanks in advance.

Can I mix a US3000C into a system with 2x US2000B Plus in the same way as you describe?

Will they self balance or do you need to balance them 1st

How long did equalisation take?

I have a single US3000C battery with a Sofar HYD 3000-ES hybrid inverter. The battery specification says it can be 95% discharged, but the Sofar will only allow 85%; is there a way around this, or do we need to wait for an inverter firmware update?

can you add a 3000 to a us2000?
