UPDATE
Still haven’t gotten a valuable response from the Jos guy. Since I dropped off the battery at vgc, I’m still waiting for him to let me know what needs to be fixed. I called him yesterday morning, he said I should allow him call the guy I dropped off the battery with and he would call me back but he is yet to call back since yesterday morning. I even messaged him in the evening as well but no response as usual.

Give him time and follow it up with maturity. I'm sure he would get back to you soon. Timely and polite response to customer's request in a time like this is very essential.
I feel very bad when I see customers bringing issues like this to the forum, an issue that was supposed to have settled just between the two parties without any third party's involvement. Loosing one customer means nothing to some of us in business but we realize the negative effect when the customer start giving negative review about our products.

I doubt the device came with those blockages. If it didn't, then it should be cleaned off

God bless you

Obnoxious2001:
This is done to prevent dust and particles from going in.
It not meant to be removed

I removed mine, cleaned it and fixed it back. If if I show you the dust that I removed from there, you won't believe.
There is nothing that's permanently fixed in electrical appliances. Bolts/nuts are provided for easily access.......

If you give it a second look, there is a sequence to the connections. The cells are first paired and then connected in series to the next cell pair. So the top connector (aluminium plate?) will show 1-2-3-4 cells and a then a break. Also, the edges of some cells can be seen peeking from underneath the bar. Therefore, it is safe to deduce some cells are there and likely to be 2 pairs to the left and right.

The harness wires should have been neatly arranged.

Hello, everyone.
What ideal inverter system (no solar panels) setup can power a deep freezer of about 200W for 5hrs and 3 LED light bulbs of 30W each?
NOTE: Solar panels (and other essentials) would be added later.
Budget: ₦500,000

If you're willing to go for a lower quality 12v 105ah Lfp battery (grade c), then the 500k will take care of it together with 12v 1.5kw hybrid inverter.
We're expecting grade A,B&C Eve Cells soon

ojeysky:
If he can increase his budget I will have suggested Deye

I prefer Felicity to SMS

durodee:
Like for many inverters or electronics it depends on many factors- Quality of the inverter itself, protection provided at installation against grid surge, lightning strikes, types of loads its being used for, ambient temperature, duration of use etc. The worst hybrid I have used so far (SOROTEC 5KVA range) lasted about 3 months before suddenly packing up, most will last years but unless you are using the high end types, I will budget 2-4 years on average before you have to repair something . The National grid with its "dirty" voltage and current is a major enemy. Off grid, the worst enemy is the element- heat/fan stoppage , lightning strike etc, etc

Apart from the quality of products, which may be a factory designed fault, every other thing you listed here is the false of the end users.
Take a look at the heating temperature of the inverter via the attached picture. Very few people do create time to open the sides of their inverter and clean the dust/blockage. Some people do not even remember it till they pack the inverter. This blockages do not always create room for air circulation/ventilation inside the system as the fans are blowing, whereby creating unnecessary internal heat within the closed system.

Sapiosexuality:
If I may ask, from experience, how long, on average, would you say a hybrid inverter lasts before it breaks down or develops fault?

To the best of my knowledge, there is no specific time or duration.
Some may last for two months, some may last for one year, some may last for five years and some may still last beyond ten years. The durability depends on many factors including the quality of the products and the maintenance culture of the end user.

RickyM:
Good evening to y’all great people
Please I’m curious about something and I hope y’all can clarify it.
What should be the battery full voltage and low battery of a 24V LiFePO4 battery pack?
Due to my knowledge, I thought each cell can attain 3.65V at fully charge and 2.5V while low?

The allowable voltage range that will not harm the cells is 2.500v-3.650v.
The working voltage range is 3.000v-3.400v per cell.
Charging above 3.425v per cell gains you nothing other than tear and wear because there is no appreciable stored energy above that voltage.

TechGeek777:
Previous policy drafted to reduce exchanged rate has gone south by the cabals, forget what you see on TV, this country na God go fit save us.

There's underground plan for it to hit 1800/$

If the OGAs at the top want it to be 400/$ it's 100% possible, but you can't close a system you are benefiting from.

It's very unfortunate and painful. How long will EFCC continue crackdown on manipulator's platform?
People were bringing the price of their products down just to clear the old stock and make purchase with the new rate because we were expecting the new price regime next month ending........
The system is too porous with fake products all over the Nigerian markets.
Please, people should not be looking at what is written on the body of products again. Just do a test or physically inspect the products to be sure of what you're buying.
I bought 1 meter of 16mm single flex cable @ N2400 a few days ago in one of the popular electrical shop in Uyo. I was very busy to really check it before making the payment. I later checked it at home and saw 16mm boldly written on the body and when I peeled off the surface of the wire, the stranded wire was too small. I removed the 10mm Daly bms cable and checked and realized the 10mm cable size and even the stranded wire were far bigger than the 16mm cable.

Good evening

Please I have this kind of configuration setup in my apartment

5kva 24v Inveter
400Watts Solar panels (5)
220ah battery (2)
60amps charger

My question is whenever I try charging with Nepa light o shows it fully charged within few minutes but when it’s on resting stage meaning when it not connect to any form of charge and I check the battery I get 77% even while on solar it shows it fully charged but at the end of the day I see 75% please how can I get it charged to 100% or should I just ignore the fact that it say fully charged and continue charging please any help would be appreciated. Thank you 🙏🏾

When it shows fully charged, shutdown the system and take the voltage reason on the battery terminals directly via voltmeter. Better still, charge the battery individually to full, allow them to rest for an hour or thereabouts and take the reason.
What type of lead acid battery are you using?

adrusa:
My AC is the regular AC, bought close to 10 years ago. The power consumption depends on ambient temperature. When the weather is hot, it consumes more power.
I haven't seen any significant initial surge as I see with the pumping machine. When it came up yesterday night about 11:40pm, the starting power was 1457W which came down to 1421W at about 1:20am when it went off. Earlier yesterday in the afternoon, the starting power was 1588W.

How many HP is your AC Boss?

litaninja:
Thanks for the details.
Trying to get a replacement for a hisense inverter ac. It used to ramp up around 1.2kw and drop to as low as 300w after reaching set temprature earlier in its life. But recently, it just maintains the 1.2kw, with occasional drops to 1kw. Its been serviced and cleaned a million times with no improvement, and even when ambient temp is pretty low, consumption remains same.
NB: Compressor hasn't been changed to a regular one.

How many HP?

swagifted:
try it when the weather is cold and see if it will maintain that 1.2kw...my LG AC been de behave like that too... But for this heat? E no de gree go down again like before.

That's how it supposed to be. Ambient temperature is the determinant factor.

230ah 24v 5.88kwh for sale @ 1m.

Drgreatone:
Must inverters nko?

Must inverter is not bad, though I may prefer Felicity inverter.

Drgreatone:
Whats the model of the hybrids. The inverter i use is connected to 3 300w panels and a 12v220ah tubular battery which rarely gets full unless there's NEPA. Have the same system at 2 other sites and its the same outcome.

I used HSI and Zumax. If the panels are well oriented and the correct size wire was used, then the charging system of the hybrid inverter is the issue.
I had an issue with of one of the hybrid inverters I installed for a customer and suspected it was related to float bulk.. I was unable to get an acceptable margin of float bulk that could comfortably charge the Lfp battery to full. When I set it to the range of 13.8v to 14v, about 9a or thereabouts was coming in from the pv but when I pushed the setting further to about 14.8v, I was seeing 25a and above. I couldn't charge the Lfp battery with 14.8v and I later introduced my spare 60a epever Mppt external CC into it and everything was in order.

Mrreed:
Good evening bosses, are high frequency inverters suitable for appliances like washing machine, pumping machine and freezer?
I am considering getting a 5kva inverter for a load range of 2500-3000w which will include any or all of the mentioned appliances.

Yes.
Though the brand of the inverter is unknown but I'll advise you work with an average max load of 2500w at a time to pave way for more allowance and the cooler of the system. I think this is way the LF inverters lord over the HF inverters. Powerful transformer Vs MOSFETs

Obnoxious2001:
It's on this thread deye and big names are been mentioned. Yes you will recoup investment faster if you go cheap

Man just needs a simple inverter that can be fixed easily and fast.
He has about 3 inverters 10 and 5kva. Then a 12kva redundant inverter. All linked together in case the the 2 active inverters has issues the redundant system picks the load.

He designed the system from scratch from the Meters to Inverter that's just what I love about the whole system

That's very nice

Drgreatone:
Unless he's getting a high quality hybrid inverter, he's better off having individual components. From my experience, the average hybrids require large panel arrays to power loads and charge at the same time. Use a small array and u wud be dependent on grid for optimal charging unless u add an external charge controller

I may not really understand what you mean by "an average hybrids require large panel arrays to power loads and charge at the same time" but I've installed 1.5kw 12v hybrid inverter 150v 80a with 2 pcs of 580w Longi pv and 280ah 12v Lfp battery for someone. He powered his 140w freezer during the day and still get the battery to float before 1pm depending on how deep the battery was discharged at night.
I'm expecting 1kw 12v and 1.5kw 12v high frequency hybrid inverter next month and I'll still test the charging system as well.
The issue you experienced may have caused by the configuration of that charging system by the company.

mctfopt:
Someone must've shared contact add or phone, but I think I missed it. Please care to repost?

Solarco contact is 0913 784 9368.

Obnoxious2001:
Yeah.
He initially started it small and scaled it up with loan which has all been paid back.
Business has been running for 4yrs now.....

He has scrapped of the lead batteries and adopted lithium....
The investment is worth every dime

He actually started it will lead acid battery? I was trying to imagine the space occupied. I admire his zeal.
To recoup his capital on the investment with time will depend on the type of products/accessories he used for the installation.
People that used Deye/Victron inverter with Deye lithium battery and Jinko/Canadian/Longi pv and other expensive accessories would have more time to wait while people that go for an average cost installation will recoup the capital early.

Buchika:
this is it. I am on a budget. My most important gadget here is the freezer, I can even reduce the usage of other loads

Dam5reey and Penuelseun advised you to go for the 24v system because of the set-up list you posted. The advice wasn't necessarily for your stated loads.
2.5kw inverter and 1400w pv were also designated for the 24v system and that was the reason they told you to change the CC from 60a to 80a and continue with the 24v system at once.
If you've not bought those items yet and you intend to reduce the cost as you clearly stated, then go for 2 pcs of 580w Jinko or Longi pv, 1.5kw hybrid inverter and 12v 160ah lfp.
This can comfortably take care of your freezer during the day, few lighting points, tv and energy saving fans at night.

Dam5reey:
I recommended the 80A for 24V system as this is CC only.

I understood you Boss. I was thinking he could still get better performance for the 12v system he's projecting if he can change the 60a CC to 80a CC and reduce the pv capacity to about 1200w
1.5kva 12v inverter max would have been a better option for him.
From my observation, he's on tide budget.

Since Wednesday the dollar has started increasing again at BDC.
How long will EFCC continue crackdown on manipulator's platform?
I was just hoping and praying that the low exchange rate should be sustained. Our porous system is very unpredictable. A lot of people are looking for a little opportunity to strike. They don't even care about the effects and the suffering of the masses. Commercial banks officials are equally part of the system manipulation.
We have a LONG ROAD to cross.
It's very unfortunate.

Dam5reey:
60A CC with 1400w panel on a 12V system is a waste of resources.
with these loads, you need at least a 2000w panel, switch the batteries to 24V 105ah use 80A controller or 48V 50Ah LFP to maintain the 60A controller
Hybrid Inverter would have been a better choice.
My recommendation for this kind of load is 24V 2KW Hybrid with 80A MPPT, 2000watts panel to use during the day also to recharge, 24V, 210Ah LFP to power night loads

Budget wise, don't you think changing the 60a CC to 80a CC can give him better performance?
If I'm working on 12v system, the max inverter capacity I go for is 1.5kw. Anything above this capacity will move me to 24v system.

twinskenny:
Hello my people
Please in order of efficiency which of this brand is good to buy …


Yohako lithium
Felicity lithium
Bluecarbon lithium

Thank you


Am looking to get 15kw worth

These three products have similar efficiency/capacity ratings.
Blue carbon might be a bit better, though I have not heard much reviews on it.

Betnomore:
In summary. This is just saying my paddy ur ways no pure without actually saying it..Wehdone

odimbannamdi:
Make I expose myself. Na me the person this bros dey talk about.. ...and I still beat myself up for missing the offer. Another thing don come chop the money... ...thanks for the patience in answering all my numerous questions, Baba. You are one of a kind. Weldone!

I never knew you were the one. God will provide another cash for you Boss. Thanks for your patronage.

mrmachine:
Very rude. He doesn't like to accommodate any other person's opinion. He blocked me too

Mek una leave my business partner alone.
Everybody is made differently. Some people may not really have time to respond to series of questions/findings/request asked by customers.
It sometimes took me a week or more to constantly attain to a customer's
findings. Some of them may not make payment at that time as they may still need to confirm the information given from other sources.
There is a guy here, I don't know his name, that wanted to buy my 160ah 24v Lfp battery
pack. He asked me series of questions for a few days. When he was about to make payment, he asked me, is your cell grade A?
I knew he wanted the answer to be "yes or no." I would have told him yes because that was what he wanted to hear but I refused to tell him yes or no. I told him that my cells are not Ev Automobile Grade Cells but they're all quality cells that didn't meet the Ev Automobile specifications.
The guy cancelled the payment immediately.. Lol.
I called him the following day and started laughing .. I explained a few things to him including the actual cost of Ev Automobile Grade Cell, how I do carry out routine capacity test on my cells when they arrive and how I do peel off the surface of the cells to check if the qr code has been tempered with. I also gave him a few lines of research on the type of cell Chinese cell reseller's called grade A cell.
After about three days, the guy came back to pay for the battery pack but someone else has already paid and carried it.
Online business require you give much of your time to potential customers and also give them satisfactory answers to their questions. They may not buy your products at that particular time as they may still need time to work on the information given but if you give them genuine information, they will certainly return for the product.

Dam5reey:
kiekie1 is your sure plug. search for his post

His water is good. I used to receive it in Uyo through the waybill when I was using tubular batteries.

Betnomore:
I have done this before but some people criticized me of doing so. That the distilled water is not really expensive and I'm likely to be sure of it not containing any impurities than the one gotten from the AC

It's good if the AC hose you're getting the water from is very clean, otherwise it's not really advisable.
I installed my ACs not quite long and their hose are still clean. My cousin has been using the water for his tubular batteries for months now. I used it too for my steam iron.
I also have TSD Meter that I used in measuring the water, including the one we're drinking at home.
