The Battery Thread (Solar / Inverter)

[B-1]

Thank you that makes sense

Not sure which inverter you have but where you connect affects where the CT coil needs to go so make sure thats correct as well.

 

[Tinuva]

That is correct in how I understand it, I am just asking what if the inverter has a fault and has a leakage to earth?

Earth leakage switch is not what you think it means. For some reason we call it earth leakage here in SA, but the rest of the world call it some other name.

The switch is there to protect humans from getting fried. Not to protect devices like an inverter. That image is correct, if its connected the way you want, each time loadshedding ends, the EL switch will trip. Trust me, the way powerforums have it, is ideal.

That is why i am asking, if the inverter has a fault that lets say makes the case of the inverter live and little old me goes and touch it or some body goes it pokes around in there do they just get the 220v shock with no protection? Just asking


Sorry posting from the phone cause loadshedding

Your inverter generate power, so erm it can shock you regardless of whether there is a Earth leakage switch inline on the grid side or not...

That's why there is earth leakage switch on the inverter output.

They call it RCD or Residual current device

Lights, for example, and any other devices wired into your DB are also not protected by earth leakage / RCD. The point is to turn off the power to them before fiddling.

I am not sure whether I understand your question correctly. I am not thus not sure that I answer the question correctly. Anyone more knowledgeable than me, please chirp in.

The Hubble S120b is a 1c battery, so one could theoretical use that inverter with up to (24VX120Ah = 2880W) load.

Probably rounding up 2.88kwh to 3kwh

EDIT: Alternatively, if the lithium cells actually add up to 3.2V x 8cells = 25.6V which gives 3072wh ie 3kwh
I haven't checked the battery specs cos I'm lazy

The inverter is 3kw, not the batteries.

Geez, but these things are getting #*@£ expensive

Never mind, I was being slow

12V x 120Ah = 1440Wh
1440Wh x 2 = 2880Wh which I guess is close-ish to 3kWh

C rating has nothing to do with this. And you can't just willy nilly switch between W and Wh (or A and Ah)

The batteries are 3kWh

 

[joker08]

Correct.

I've got 5 batteries with 3 different models.

3 x US3000B
1 x US3000C
1 x UP5000

Parallel, definitely parallel.

Pylons all talk to each other, so you simply hook up your extra battery (ensuring the newest model is master) and you're good to go.

Parallel,Pylontech's manual has a compatibility list for which battery becomes master in a config,their entire range is retroactively stackable (only manufacturer I know that does that with so many models)

I am trying to add a new UP5000 battery to my existing system. Now I know u get interlink cables with a new battery to connect to an existing battery but i cant find out the length of the new cable that will come with it.
Issue is the new battery will be next to the existing battery are not one top of the other, so I am worried if the length of the cable will not be enough to parallel the batteries... same with the coms cable.

If the length of the cable is not enough, how do I purchase new connectors and make a custom power cable and coms cable myself?

Interesting. I have 2 Dyness 4.8kWh batteries (A48100). I haven't decided yet whether to spend more money and get a third battery. The problem is that the Dyness A48100(4.8kWh) seems to be gradually being phased out and replaced with a 5.12kWh model (BX51100). Is it possible to parallel the 5.12kWh model with the 2 x4.8kWh models?

You would have to ask the manufacturer

It is not possible. The 48100 is a 15cell system while the 51100 is a 16 cell system.
