@bright, awww ! What really transpired between you & that Lithium seller

dat guy de use piple money de experiment. ..a bloody tif. Make e try am com post anything 4 here first. E nor go fit confront me 4 here sef.

Hmmmm...make i comment my reserve on top sellers n buyers.. my own de front de com

Make i go give oga @valto wine 4 house make e take clear throat cos d matter go hot

I don warn one ps here make e nor bother com nairaland com advertise. I de wait 4 am

No Wahala..
Afraid dey hold some of us when we see price.. ..
Besides I already know the solution, however I was look for an already made system that can work independently with a preset voltage level.....

I was thinking of coming up with a simple analog comparator circuit, to notify the user when it has gotten to 24.5v

But enjoyment too sweet they fit ignore am, so I wanted a cutoff system instead of a notification system.

haha but ideally 25v is ok

You should try a PCIe Gen5 NVMe M.2 SSD with blisteringly fast 12,400MB/s read and write speeds with an endurance of 1000TBW per 1TB of capacity. That gives you 2000TBW for the 2TB capacity drive, or enough to rewrite 1TB of data every single day for over five years on a compatible mainboard, thank me later.

Files and Bandwidths have grown bigger lately, after my Inverter setup I decided that I will have to do away with my 32TB WDMyCloudEX4100 NAS and 24TB HPE Proliant DL380Gen9 Server. They became too slow for my liking.
Despite having laptops like HP Omen, Lenovo ThinkPad P43s, HP AIO 24-df1270, HP ProBook 450 G8, all with minimum of 2TB NVMe SSD, I still find it slow pulling files from my NAS and HPE Server especially media files.
So I decided It's time to go full blown SSD.

My latest config goes like:

To replace my 32TB WDMyCloudEX4100 NAS I will use:
ASUS ROG Maximus Z790 Hero
LGA 1700(Intel®13th&12th Gen) ATX Gaming Motherboard
Intel Core i9-13900K Gaming Desktop Processor 24 cores (8 P-cores + 16 E-cores) with Integrated Graphics - Unlocked
PCIe 5.0, DDR5,20+1 power Stages,
2.5Gb LAN, WiFi 6E
Bluetooth V5.2,
2X Thunderbolt 4 Ports,
5xM.2, Thunderbolt™ 4/USB4)
5x4TB Seagate FireCuda 540 PCIe NVMe Gen5

To replace my 24TB HPE Proliant DL380Gen9 Server, I will use:
HPE DL380 Gen10 Plus 8LFF CTO Server
2x Intel Xeon-Silver 4314 16 Core Processor
2x 256GB DDR4 3200
16x 1.92GB SAS SSD
2x 10G SFP
etc.

All these items have arrived except the Intel Core i9-13900K Proc.

Pictures of my setup will be made available on demand.

na solar thread we de ooo... btw ate u running gen 5 pcie nvme ssds for home use.. daz an overkill except u have bunch of containers n virtual machine powered up. Sfps com join 2 4 dat matter.

Me i like mini systems for my home lab i nor get power resources 4 dose hungry Proliant monsters. Planning on getting one of these i9 10 cores 20 thread pcs with at least 64gb ram configured with 10gb sfps nic running proxmox to connect to my NAS. I might just decide to have a cluster @ home to run kubernetes. 4 me i dont see ssds taking over the traditional hdd space in terms of storage. No matter how cheap ssds may become.you can check out tiny home project series[url] https://www.servethehome.com/introducing-project-tinyminimicro-home-lab-revolution[/url] Enterprise gear and its resources is a no 4 me wen i can achieve more with less.

Obnoxious2001:


You where making sense until your closing remark.

That inverter you dey try inform me about I no go buy am from you .

I go buy am from who no put him problem ontop him Market...

Pax vobiscum

loo... so u mean say marketeers de add family problem on top dia sales. Na wa. Make una temper justice with mercy

olopan:
Short answer is NO!

Ordinary fixed rooftop of top equipment is problem for some due to cost, not to talk of solar tracking array, the reality is that i don't see it being economical solution here in Nigeria, my POV

just like u said cost is a big factor here. Open space is another abi na landlord house u won do this one put

incogni2o:


are you saying all inverters are equipped with that feature.

I guess the inverter i had should have same feature, but the voltage range didn't sync properly.

could also be that the battery already protected itself before the inverter did

Not all inverters have this function. But i think u can program this by using a user defined setting esp on hybrids. This is one thing abt lifepo4 customization. If i cant interact with the bms to allow for certain voltage disconnect then am not buying. Its either the inverter disconnects the battery from operating further or the bms can do that. Btw wat is the bsttery voltage?. Did u check the voltage @ the terminals to ascertain if there is still power across d terminals abi e don enter 0v

ameh99:
our 50AH 12v can power a 322" Led TV set, decoder, 2×5w led bulb for upto 8hrs


call/whatsapp 09068448005

u nor de hear word abi.. no prob

incogni2o:


Its likely due to.you using an.hybrid inverter.

A Blue Carbon battery I installed have also been drained about 3 times now.

I think its a bit lazy for the company to.allow the battery go so low before triggering it off

Inverter charges it via generator and it comes up back.

Get a non hybrid inverter to charge it.

its under warranty though, I could assist you how to return it to be checked

what happens to a low voltage disconnect. Your inverter should be able to disconnect your battery @ a particular voltage set on it.

We have 4G router too for free

boss i need this speed.i don tire 2 buy data. Wetin make dem de peg the device only @ 5g. E nor mske sense. The 4g own na data base subscription na boss


So if 5g goes out which is bound to happen 4g nor go work

ameh99:


I jhave nothing to say to you than to ignore you

y

just quietly open your own thread and advertise there. That is the only leverage you have. You tink u kno how to do business. You will not advertise here

shopnig24:
Wow
The Airtel 5G Speed based subscriptions has been upgraded

i feel like crying. I called one number you posted jane to be precise. She said it cannot work in non 5g areas. So this tin nor fit switch btw 4g n 5g. Make una help my ministry oo

ameh99:


you are very irresponsible and childis be very careful

my Monica has been existing on Nairaland before you even bought your first smart phone, you can check it

if you lack home training that's your problem

u de threaten me? Na pikin wen never go anoda person farm go tink say e papa own big. Go n check wen i registered on nairaland, dat time u never kno wetin dem de call internet. U still have the guts to com n open ur trash to tell me am irresponsible. The last time i spoke to you on phone i told not to bother advertising on nairaland. I trusted u very much but u took me 4 granted. I can never forgive u. NEVER

Edrizz:
Why chatting in parables, if u have any negative review about the seller, why not say it out once n for all.

are u new here

Edrizz:
Are you discouraging him from patronising d lithium battery seller or what?

u will com here n testify

gadgetplanetng:
Looking forward to getting & reviewing mine

dont say u were not warned. Premium tears awaits u

samir101ng:


I have been reporting and posting this on the thread & DIY Solar Telegram group for a while now. I attended the conference flying in from Abuja for three 3 days. The conference this year was even more massive and had a lot of Vendors in attendance from Fronius, Victron, SMA, Anern, Felicity, TBB Power, Xtra Power, SRNE, etc. I will post some pictures from the event soon. The conference has had maximum exposure as the current minister of power Mr Adelabu was at the event. I have also been seeing their sponsored posts on linkedin, youtube and online.

sent u a dm

shopnig24:


Subscribing and using it for a year

doesit have an ethernet port

shopnig24:


Yes boss. It will automatically pick 4G

i wil b willing to try this 5g device.. i pay 15k for 75gb 6am to 8pm with the same bandwith allocation. 8pm to 6am is not data capped.

shopnig24:


It's dual band.. 4g, 3g whatever is available works.
And the moment 5g is available it works effortlessly too.

i just checked my location now. 5g is not available. Will it wiork under 4g

In simple terms, there are 3 types of Inverters.. . The cheap one used to simply be square-wave, that is ON + for half the cycle and - for the other half cycle. . . OK, for lights, and heating equipment, did work with computers and some other stuff, but probably not very good for them.. . Very high in 3rd harmonica and other odd harmonics as well. . . Then they improved these by having an OFF period between the + and - .. . These are “Modified Square-wave” but the naughty manufacturers call them “Modified sine-wave” which they certainly are not.

Then, in the old days, we used to have real TRUE Pure-Sinewave Inverters.. . These were proper sine-wave and very clean, even cleaner than the grid supply, free of any harmonics or any other products. . . . They worked very well, but they were inefficient at converting DC to AC, and so gave off a lot of heat.

The more recent, particularly larger modern Inverters use a form of Switch-mode, often referred to as PWM. .. They switch the DC feed to the output, often through a transformer, in very fast On/Off pulses. . . The On and Off period ratio, sort of matches a sinewave approximately. . . . So with efficient output Filtering, their output is fairly close to a sinewave. . These are the true Modified Sine-wave inverters. . . The filtering blocks most of the harmonics, particularly the higher frequencies, their outputs are good for anything that normally works from grid power. . . But they are NOT True sinewave as manufacturers call them, but they are very power efficient, typically up in the high 90’s %. . . Some claiming 98% efficient, whereas the actual True Sine-wave, as I mentioned before, from Linear Inverters, were perhaps only about 60% efficient.

The outputs of inverters that are power efficient have a lot of harmonics.
Back in Engineering 201 (I think it was the sophomore year) we learned about the Fourier transform and how any waveform can be created with a series of sine waves with different frequencies. frequencies.

The attached picture shows what happens as you add odd harmonics (3*F, 5*F, 7*F) to a sine wave. You can see the sine wave starts looking like a square wave.
A square wave, or any rectangular switching waveform, has a bunch of harmonics present that are often significant at more than ten times the square wave frequency.

For some equipment this is no problem. A lot of components today such as chargers and displays just rectify the AC input right away. Harmonics either don’t matter or they are mostly filtered out and don’t cause a problem.

Magnetic equipment, such as motors and transformers, are not so forgiving. The magnetic material in most line frequency magnetic components is a silicon steel alloy that is chosen because it works well at low frequency, 50 to 60 Hz. The losses of silicon steel increase rapidly with frequency. If there is significant energy at 500 to 600 Hz the loss of the magnetic material causes it to heat up.

Things like refrigerators, fan motors and old equipment with a line transformer can all be heated enough to cause failure.

In many pieces of old equipment the AC inputs are not as well filtered and the higher frequency harmonics can cause noise and interference.

An inverter that doesn't produce pure sine wave energy can have a number of negative effects, including:

Reduced efficiency and increased power consumption. A non-pure sine wave inverter typically has lower efficiency than a pure sine wave inverter, which means it requires more power to produce the same amount of energy.

Reduced performance of some electronic devices. Some electronic devices, such as some types of motors, are sensitive to the type of power they receive and may perform poorly or not work at all when powered by a non-pure sine wave inverter.

Increased electromagnetic interference (EMI). Non-pure sine wave inverters can produce more EMI than pure sine wave inverters, which can interfere with other electronic devices and communications equipment.

Reduced lifespan of electronic devices. Some electronic devices, such as some types of motors, may have a shorter lifespan when powered by a non-pure sine wave inverter.

It is important to note that these negative effects may vary depending on the specific device hor equipment being powered by the non-pure sine wave inverter. It may be best to consult with the manufacturer or a qualified technician before using a non-pure sine wave inverter with certain devices or equipment.

abeg na... this one u de introduce fourier series. E remain laplace transform for u to add.abeg allow us to manage our inverters in peace

Uchman81:
It's a hybrid.
Heats up easily while charging with Nepa, the fan stays on through out the charging period.
Damaged my laptop chargers. (All those kikiki sounds, from there the charger will stop working)
Haven't loaded it more than 300 watts so I don't know how it handles load.

i don run

@ op wat happens if i dont have 5g in my location.

Uchman81:
Those prices are tempting, if the distance isn't that much, you pay him a visit.
Keep us posted, will like to get the Felicity 5kva hybrid inveter as my Must 3kw inveter isn't serving anymore.

please what happened to yours. I AM Looking for a detailed review on the must 3kw 24v inverter.is it a hybrid inv or Standalone
