PV generate around 3kw..while load is btw 500w and 650w max.. And its only btw 1.5kw and 2kw that goes into the battery.. Sometimes abt 1kw Wont be able to be accounted for..

Display meter may be wrong...you may need to verify this generation and battery charging amps with a meter.

Haykay2001:
Thanks chief.. Will ask them they take me tru the configuration via vidoe call.. But i doubt they will touch or tamper with the settings i did there sah.. The system was installed April this yr.. And has been perfectly fine no until abt 2 weeks ago..

Their load might have increased. Check load/PV production.

Tdoctor:
Will a buck converter work? Any one with experience?

Yes it works.

This is the type I was using before I upgraded: Power Supply Module XY6020L

Please where can I get an adjustable lithium charger/DC power supply that does 0v-60v and can charge at >20-50 amps?
This top balancing is sloooooooooooooooooow; the device below is unsuitable.

AliExpress

I have this charger. Got mine in Alibaba some months ago.

I see hzsolar on the pic you posted. Though I've settled for my home after discussing with current users. What's your take on hzsolar DC submersible

MyHome not bad.

ajabani4allah:
Could this battery be original? I saw it on Temu. I want to consider buying it but I am doubting the capacity?

At most I'd be 2600mah

Dreamhans1:
it's just for a farm and there's a ground reservoir. Also I wouldn't want a batteries system. Na Nigerian farm. I wish you know what I mean

Get a DC solar powered submersible pump. With 4/6 nos of 400/500w solar panels you are good to go.

Tdoctor:
This is what I came up with. Thanks to everyone who helped me decide.

My thoughts on DIY Lithium
1. It is stressful. Only embark if you do not mind the stress. It is NOT a walk in the park.
2. You must know basic electricity principles. If you do not know how to check for continuity with a multimeter, it may be best for you not to continue. Read well and research before embarking.
3. First builds come with mistakes (I did not top balance, so my BMS is currently being overworked. Thinking of opening the case to charge some cells individually. Tips will be appreciated).
4. If you do not already have tools and materials from other projects, it may NOT be cheaper than buying, for the first build. I could cut down costs because I had materials from other projects e.g. 250A MCCB.
I cheaped out on the terminals; I used the hanger that came with the electric cabinet.
5. It is FUN and you will learn a LOT - wiring, behavior of materials, tools, etc. Subsequent builds will be much faster.
6. Before you use cheaper materials, do your research o. I abandoned the wooden box I created and went for metal after suggestions on this thread, because this is my first LFP build. Mrreed and Valto can use wood because they are experienced and have some design secrets first timers do not have. Safety first, if you are a first-timer.
7. Double-check everything. I went through all the screws again before deploying, only to find out two were not well tightened.
8. Youtube videos from foreigners are mostly useless when it comes to procuring materials. A lot of the things they have there, we do not have or are difficult to source (e.g. fire-resistant cement case and fire-resistant graded wood). Seek local threads for guidance.
9. Eat well before embarking. Drilling and cutting are not easy.
10. Stop working whenever you are tired, before you drill or cut yourself.

Well put together. Nigerians are super resourceful. Saw a dude do a 5kwh lithium battery that you can hand on the wall with the empty casing of a busbar housing! People got mad skillz in Naija.

RickyM:
Thanks for the suggestion…I eventually nailed him, his house is just opposite the pharmacy I figured out.
I got my money back too!

Ok, that's great.

twinskenny:
At all at all bad pass...


I have a friend who has purchased everything including panels but the landlord refused! He even offered the landlord 500k upward compensation.. still landlord won't agree

.

Let him try ground mount, fence mount, awning design, balcony mount etc

Maybe the landlord has a phobia for roof.

twinskenny:
Nawa

Landlord could've warned them against a roof install. Gotta do what you gotta do to get some sun on those solar panels.

BigDickProblems:
How about a Shocking Hot plate?

It was not shocking when initially bought, but now it’s shocking, when you touch the pot you placed on it; you feel that electric movement.

Check for leakage voltage which may occur due to breakdown of cable insulation which happens due to heat generated by the hotplate and corrosion as the hotplate gets older.

Machiny:
Please any solution to hotplate wires and connection point getting burnt?

Replace with appropriate sized cable and replace socket with good make. Connections and contact not strong enough leads to arcing which leads to burning.

RickyM:
Already narrated what transpired which is the deal fell through and he has refused to refund on the day he promised and to crown it all he deleted his WhatsApp account and his number has been saying busy.
Like I said, it’s so unrelated which mean the person isn’t a Nairalander.
Just need the right contacts (any force)

You can give it a try

dollarnaira:
No join me oo
Na Satchet inverter ooo

Oh. I see now.

Oshomo12:
Actual inverter capacity is 2000w continuous and 4000w peak

It's clearer now

dollarnaira:
Go Diy 12v
Cells 314ah - 3.76kwh 360k
Active balancer - 35k
Inverter - 160k (4000w)
Cc - 102k
530w bifacial pv --92k

U don't need installer.

You go pump water sef...
Na just small sense ...

Abeg which inverter is 160k for 4000w?

BigDickProblems:
From my ever-learning knowledge so far, 530watts panels is not suitable for your 12v system. Panels of 18V Maximum power voltage and open circuit voltage (VOc) around 22V-24V which are usually in the range of 180-200Watts are most suitable.

You 530Watts panels definitely overloading the controller and thereby causing the overheating in the controller for it trip off.

You must have followed the advise of getting a big panel and not the smaller ones.

With adequate charge controller you can use any size of solar panel

fuckboys:
Omo eh, this bread inverter just deu give me joy. I keep seeing issues everywhere and I've never turned off the inverter or checked my battery level even after 5 months of installation.


Just there doing it's thing and supplying constant electricity 24/7

God don butter your Bread

Unfaized:
How do you guys calculate this power draw?

For instance charging my battery at 15 amps is pulling about 400w using generator.

Please educate me.

With a meter you can see power drawn - current, voltage and of course the power.

With a clamp meter you can check the inverter input current, if you measure the voltage the product of the two is the power.

favouredbymercy:
Good day senior men

Please does anyone here know about this stabilizer? Can it power a 1hp submersible pump?

Thanks for your reply.

The maximum current draw of a typical 1HP submersible pump is between 6A to 6.5A that is around 1500W. So a correct 5000w AVR should be able to power that

Tdoctor:
I'm particularly interested in H*KVision and D?hua. I don't know if these camera names are keywords for banning

Try 1688

capnies:
Please our lifepo4 battery builders where do you buy casing for your projects

You either construct one or buy from China.

FEGEITOK:
I second this.

Our generator repairers are notorious for altering the frequency of petrol generators because 1. The noise is too much and 2. Maybe they think it will use less fuel

You know how it goes.

Also given that most devices can still work with horrible frequencies people don't know that this may be an issue.

Unfaized:
Hi. Thanks for your input. Fortunately this issue has been sorted.

I lowered charging current to 15 amps and that was the sweet spot.

Oh, I see. This was a capacity issue. Glad you've fixed the issue. Totally hate the use of generator ..but I understand people who do. I don't own one.

Unfaized:
I own a 3.5kva Generator, my inverter is 24v 4.2kva. No matter what I do it won't charge from the generator. Even with charging current lowered to 20 amps.

Whenever I turn on I always hear a clicking sound from the inverter and the light will be flickering. My system is grid only for now. How do I go about this?

Your generator frequency may likely be the culprit. You may need to replace the AVR of your gen. Or adjust the speed to see if you can get between 48Hz to 51Hz.

Most petrol generator produces terrible frequencies of about 40Hz or something like 70Hz. These type of frequency are often not compatible to battery charging.

Odunsijr:
Good afternoon everyone, please has anyone here ever received a refund successfully to their bank account from AliExpress? If yes, how long did it take?

3 to 20 business days

dollarnaira:
1hp is not 745w in real life oo
0.5hp is doing 792w i.e 66A at 12v.

True, my 1HP AC power fluctuates between 250w to 1100w depending on set temperature, mode, or ambient temperature. But I notice it is an average of 400w most of the time. LG Dual Inverter did a wonderful energy saving AC here.

oladele239:
Not the one I ordered though
The problem is many of you don't take time to read reviews before shopping on Temu...

Stay blessed ✋

if you don't mind which make did you buy?

twinskenny:
Yes boss

I'm sure the production will be superb. Amazing work by the welder. Good job here.

twinskenny:
What we setup in in enugu!

Did client buy bifacial PVs here?

justcallmenuel:
Solar panel not included sir

Thanks a lot

justcallmenuel:
57,000,000 (it’s an all in one).

Is this inclusive of the 120KwP solar panels or only the 100kw PC and 215kwh battery?
