Lol. Bàbá wan hit jackpot

So it's actually 120Ah?
This one pass highway robbery if true.

Edit: I was already salivating at the prospect of stacking 5 of them to get 1000Ah 48V dc lithium bank!

ojeysky:

If the felicity actual capacity is 150AH/48V and not 120AH and if the cells are new then I think it's a good deal at that price.

@NiyiOmoIyunade
This was taken yesterday morning.
It's quite interesting what one can do with emoncms and the plethora of data from my Victron inverter.

I'm going to add night and daytime energy consumption to decide which heavy loads i reaaaallly need to transfer to the Critical Loads DB
Night time = 5pm to 7am (currently averages 15kWh with one aircon on)
Daytime = 7am to 5pm (averages 15kWh as the Heavy Loads DB is currently off due to ongoing renovation works)

APPLIANCES:
Approx. 500w (8 hours) Day time loads = 4kwh
1. 1kva 12Vdc Inverter
2. 4# 300w solar panels
3. 60A CC (Capable of charging Lead Acid or Lithium)
4a. 2# 200Ah 12V dc nominal Lead Acid bank or
4b. 2# 100Ah 12V dc nominal Lithium bank
5. Isolation and protection accessories

Energy Storage @ 12V dc nominal: (8hr DayTime Use)
400Ah @C10 - Lead Acid: 4kwh (50% - Useable = 2kwh) or
200Ah @C2 - Lithium: 2.5kwh (80% - Useable = 2kwh)

Pv Array:
4kwh generated in 4 hours of sunshine = 1000w (4# 300w panels)

Source Priority:
1. Solar
2. Battery
3. Grid
4. Gen

You can comfortably get away with 1# 100Ah 12V dc Lithium battery and 2# 300w PV if the array performs at 4kwh/kw efficiency.

limpopo:

okay, the breakdown.. I don remove some gadgets shaa

43inch TV - 80watts
sound bar --- 70watts
led bulbs (5watts) -- 8pcs -- 40 watts
decoder -- 30watts
phone chargers-- let's say 10watts(10* 5phones)--- 50watts
fans--- (4pcs *40watts)--- let's say 200watts

All the above calculation Na 470watts

So, 470watts for 8hours

Very nice!
Unless i missed it, can you elaborate on the bolded? I suspect you'd have been better served with a 3 phase 5kva build .

A typical Quattro's second output is limited to 50A ac, around 10kw.
This means your heavy loads are at 10kw or lower. If higher, do you use assistants to start a Gen to Power Assist? I'm assuming your loads are split into Essential and Auxiliary loads.

NiyiOmoIyunade:
A quiet weekend allowing me to benchmark my home-office energy system performance and evaluate the design choices I made with single phase 15kva vs 3 phase 5kva

I now understand what those angels who lust after the daughters of men went through before saying "fck it, we die here!"

Good one Mr Niyi!
60kwh Lithium Na to form mini-grid begin bill my neighbours.
I also need a display in the kitchen.

NiyiOmoIyunade:


As an enthusiast you just want to keep trying out stuff.

My PylonTech source believes I still need another 20KwH to round out my system I just smile, he does not know that I had to sell one vital organ and plan for a long time to get the current set.

Any further spend na die be that o!

If the bar dey and you no dey owe, plus a sizeable investment nest egg, then by all means splurge!
I get DIY Lithium in my gunsight

You only live once baba.

It's like inverter appliances will be my next target of investment, aswear. But it's only ACs, freezer, fridges, washing machines and microwave oven that covers that terrain of inverter tech.

The 203L Haier never even reach one year and I'm already itching for this. that was how I retired a new not too efficient 42 inch LED for an A++ efficient 65 inch after 6 months. Because I couldn't get to sell the former quickly, I was forced to give it out against my wish.

I'm worried this extreme urge of acquisition is not bordering on some abnormality.

It means that the total Solar ENERGY generated that day was 53.56kwh to feed house loads and charge the batteries.
That same historic day, his panels went berserk and pumped 12kw of power to 4 charge controllers for a few seconds
causing them to angrily spit over 220Amps unto the hungry DC bus for the inverters and batteries to snag up!

Everyday the house makes unreasonable(reasonable?) load demands. The inverter doesn't care, it simply takes it from the DC BUS.
The batteries and charge controllers are unfortunately on the DC BUS. So, one or both of them must feed it. It's a rat race!

tonididdy:

Pls sir in lame man terms, what do this figures mean... Pls

Penuelseun,
Two independent Relays switching power to a load is very dangerous!
The likelihood of both latching the same time is very high.
Relays fail all the time, i work where this happens regularly...

To mitigate, consider using mechanically interlocked contactors. It's physically impossible for both to energise at the same time.

I'd like to stack 4 of them in parallel for 30kwh 48V. Is it possible?

NoMoreTrolling:


Wow, I can’t believe it!

Someone should please run a test on this batteries. They seem too good to be true.

7.5kwh of lithium for 600k?

Anybody in the house using them?

Mine is downstairs, and it also doubles as my study.

cretin:
...extra room in the duplex dedicated solely to power/inverter and the space will also serve as my study...

microgiant:


Kindly share the energy consumption rate.

No idea. I sold it as soon as i got it.

mctfopt:


This tv is very popular outside of Naija. In fact in places like North America, TCL is the popular choice for most people.

I sold this Tv the following day after buying it. I found out i couldn't install PLEX when i took it home. Very nice tv though.
As others have mentioned, I look out for energy savings option AND Plex capable.

@Adrusa,
Good talk about energy isolation.
Always ensure ZERO energy before working on an energized system. Double check or get a second verifier
I've had many near misses in my tinkering career. Now I just pay people to do the work while I supervise.

Nice! I also want to read about your review/experience(s) so far.
I plan to go that route, but the amount of rework necessary to adapt to my current setup looks daunting.
How did you modify your AC water heater connections?

essegis:
I bought and installed this towards the end of last year. I have a big family so I bought the 300ltrs own.

What is the cost of production of Nigerian Crude?

That's not Nigeria's crude.
Bonny light crude is what we sell and it's currently trading at $22.

Commanderinpips:
It is trading at $10/barrel already.

The bolded is the current reality!!
If this madness continues till June/July, then very serious wahala go dey.

If you have dollars, guard it with your life! Spend only on basic needs at this time.

sassysure:

Naija no get any place to store oil except ships. None.
All our oil dey ships for sea. Almost all our ships are loaded and floating in the sea as nobody is buying.
The news was here like few days ago.

How can we not have land reservoirs?

What is wrong with these people or they never envisaged a day like this will come one day?
That's why I call them low IQ politicians

Madam all the suggestions are great as long as you have house loads sharing the 60A from the suggested CC.
That kinda current on a 200Ah C10 battery bank alone may "overfeed" it.
An "overfed" battery condition develops when it receives current far in excess of OEM recommendations.

queenfav:
.

This is good information! Will exercise due diligence.

NiyiOmoIyunade:
Locally you can buy the Victron Lynx In for a pro solution but a bit pricey. In my experience, it could break if you tighten too much...

Yes. You don't need an external anti-islanding device to enable the ESS assistant.
You need a GX device though.


I have mine set as above, but with the LOM AC input 1 and 2 reversed cos my Gen is on AC input 2 and Grid on 1.

Follow this link [url]victronenergy.com/live/ess:design-installation-manual[/url] to learn all you need to know about Victron ESS implementation.

DADAL:
Greetings to everyone. I have a Multiplus 3Kva and doesn't have a external anti islanding device. Is it possible to use ESS without installing an anti-islanding device?

EnergyMotive:
We are looking for a Solar Technician that can test and advice on an existing solar system installation in Ibadan. This needs to happen fairly quickly. Please send interest with qualifications via WhatsApp to 0808 214 6659. Thank you.

Just get 2 batteries and 3000w panels according to our resident "expat".

truthbetold22:

Why should I be bitter or jealous over a solar installation? If I had just 2 batteries and had constant electricity, have I not fulfilled the same need as Niyi? Do I need to have 50,000 Watts of Panels when 3000 watts can do the job? I must be very dense

Haba! See the way you're foaming at the mouth... Jealousy kills!!
Earn and spend your own money. You reek of so much bitterness and poverty.

So much bitterness and jealousy in one post!
Projections... You cannot project your lifestyle unto another whose bills you do not foot! Na ya money?

Go which route?

zeestone99:


Pylon we go. Don't worry when I'm done. You would be convinced to go that route considering the size of your array.

earthrealm,
This looks like you want the same Pv array to feed both the Fangpusun charge controller and DC Submersible pump. I've read in several fora that it's not a wise thing to do.
I believe you can achieve what you want by the use of a 12Vdc 2NO2NC contactor.
Connect the pump to the 2NO contact, and the Fangpusun CC to the 2NC contact.
A level float serves as the permissive to energise the contactor allowing the sub pump to refill the tank.
Add a timer in series with the float switch to energise the contactor on low water level between 10am and 3pm.

Remember you will be switching DC under load. Use of a properly sized DC contactor cannot be overemphasised.

Buy locally baba, no take chances o!
I don shelf my China Lithium purchases for now

ojeysky:
I found some on AliExpress but will be good if I can get one locally

@Ojeysky, look ya post and run through ya numbers again.
The thing no jive at all...
