Abeg are you powering your neighborhood? This is too much na. I'm sure even my street transformer no dey reach the level of kwh every day

are you offgrid?
care to list the humongous loads you have chopping all this kwh?

You no lie. The mere fact that you have all that power free from nature is exhilarating.

I came across this website that discussed how the inverter appliances work and went ahead to compare inverter frighe offerings from Samsung, LG and one intellisense manufacturer like that.

Inverter frigdes are the bomb, your battery bank will not even do any work overnight with an inverter fridge. The website went further to explain that LG even has a still better offering with their use of "linear inverter compressors" which is further energy efficient than Samsung's inverter compressor.

I'd have loved to change my search to LG inverter freezer but apparently LG is yet to have an inverter freezer for Nigeria, cos what I saw written boldly on the thermocool I saw today is: "Nigeria's first inverter freezer"

saw the freezer on jiji, worth checking out if you are in lagos, as ad was posted 16th June

Hello guys,

Anyone got any idea of how I can bottom balance my LiFePO4 cells? I don't know what takes 3.2v and no equipment to use and transfer its charge into another set of batteries. Any idea is welcome though.

Im sure sha if I check this house properly I will see my new box of resistors (though not the box type). And I don't know which exact amount to use to drain the bank appropriately. Any calculations for things like these?

See bank below.

What I saw one guy (Will Prowse) use in a you tube video was 20 watts resistor, if I remember quite well.

The resistors you'll have at home will likely be the smaller ones, and I'm not quite sure you can use those.

@ceaser
Thanks for your comment.

Apparently someone has a better idea for connection.

Edited: I see you've read Niyiomolyunade's deposition.

babaegun:


@NiyiOmoIyunade

Thanks for your comment too. I intend to use option 3. I will also ensure equal cable length for the battery banks.

@the bolded. Can you explain further or depict it with a rough diagram.

For the bus bars, how thick do you think a a bus bar should be? Very thick or very light?

Cheers.

Where can you get those thick bus bars in Nigeria?

Yeah, I don't have those Will Prowse white centered resistors but the pack I have has different ratings from 0.1ohms to I think 1000ohms sef. E plenty. But na normal small body resistors so I don't know if they will work or the exact rating needed for the discharge.

Is top balancing not working? You can always buy this capacity tester that can act as load.

brother, I've been offgrid for close to 2yrs now.
just recently before the lockdown (march to be precise), bedc was forced to send me a note complaining
that i haven't recharged my prepaid meter for a long while. i just laughed in greek

Why will you recharge? You should be selling excess generated power to them na. Lol

If you can up your budget to 10kva then get a dunamics stab.....it simply rocks!

Hi, any link to where it can be purchased, pics or something helpful?

Thanks

Can't seem to find it on Jumia anymore

One of the reasons I now go for external chargers. Over the years I have packed and condemned inverters with either bad chargers or bad inverters. Going together is NEVER a good combination.

Cheap Chinco "Reliable" I bought since 2016 is still doing the job, no chargers attached.

is it 48v?
you know of any budget 48v smart battery charger?

ceaser:

Where they sell electrical materials for earthing.If you want something thicker, try shops selling L.V substation materials ask for copper tape.

earthrealm:

They have 48v too

The AC output i have seen are mostly 120V, reason i really don't like it. i need my 220v to 230v confirm
But their products is very rugged

Nah, they always ask you to select specifications before buying. Just go ahead and do either 220 or 230 and you're good.

[quote author=microgiant post=5454016][/quote]
Is it advisable to charge inverter battery with a prepaid PHCN meter? How many kwh units does it take to recharge a 200aH 12V battery using a 1kvA inverter?

essegis:


Guys, the last set of these batteries just came in. I can now start building. Too bad I'm still stuck at work and would also have to do a basic build on the first run. No BMS, breakers or isolators. These will come in when Corona allow economy start to move freely again.

For now my people need an alternate source of power so my old remaining DC fuses would just have to do for the time being.

Are these cells new? Cos i saw them advertised as used cells for $9.99 per cell somewhere else, although stock was sold out.

Blueprintz:
Thanks boss, have gone through this thread and have not seen any device for LVD, but people always advise for 50% DOD (how effective can one monitor a system at night)..
Which anyone can point me to a LVD device

There are many cheap circuits that can implement set voltage cutoff and reconnect. I even built one in my early days with solar as a charge controller. It simply connects or disconnects pv based on battery voltage....you can use it to switch relays for you battery if thats what you really want to do.

Check aliexpress for battery voltage monitor or something along that line.

What's the price tag?

The lowest is 575K

Wondering why a seller will stock 120v equipment or inverter here when he knows our system is 220v. Surprised is an understatement here.

Anyway, I was talking about AliExpress. Abeg go buy for there, choose 220v and universal socket and you're good. Though once them see you're buying from naija they know what set up you're looking for. Cheers.

I'm sure I'm one of the reasons it was sold out. Did you see my set up?

Cost about 3k to setup, used a 12v adapter to energize the relays

Schematic diagram pls?
