Thank you for your contribution. Looks like my current inverter is not fit.

I will get to that level where 3million is tight budget by God's grace.

GeorgeD1:
so, 9yrs ago to the day, i installed and commissioned my protek solar water heater.
for those who were on the thread back then, recall my review after 1yr on may 17th 2018.

it has really been a bittersweet experience and finally in march of this year i decided to bite the bullet and do an outright system replacement.
this is coming 6yrs short of the promised 15yr lifespan of the solar water heater.

did it serve its purpose? will i do it all over again? the answer is a resounding yes! but not with protek, which happened to be only a white
label product manufactured in china without after sales support.

Are these SPDs connected to earth? How good is the earth? Find attached the resistance of an "earth" in someone's house.

I love this review.

Most Chinese brands, especially in Nigeria, hate the after sales service. Some even will start fighting you after two months if you have issues.

Which brand did you go for now?

GloriousGbola:
your average electrician is working without any kind of supervision and deploying the cheapest and most non standard solution for you.

the earthing of most homes is likely nonexistent and once you are in marina or lekki which is sand filled, you are on a looong thing because they need to dig past all the sand to get to the true earth.



i am not sure most Chinese brands in nigeria are brands in the true sense of the word but just Nigerian hustlers selling variants of the same item with different badges - built and designed to look good in the showroom but not in the field

most western brands have their literature online and suppot forums, and discussion groups. your average chinese brand sold in nigeria, information begins and ends with a jpg on a sales webpage. i dont think this is on the chinese for teh most part though - but in GIGO where nigerians get rich by deliberately procuring , building and selling dodgy low quality items built and low cost, sold at high cost, and deigned to not last

chadbasin:
Morning house, please does anyone sells or knows anyone that sells Ebikes?
Please reach out
Thanks

SourYoghurt:
no, the entire system is not earthed, everything is just positive and negative.

Machiny:
Who has 48v sachet inverter for sale?

Valto:
3000w 100k
4000w 160k
6000w 215k

durodee:
I am sorry to te you this : your had absolutely no security!
SPD that is not earthed is nothing more than decoration.

SourYoghurt:
lessons have been learnt, can anyone help with sketch of how the earthing system will be made, I don't trust my installer to deliver a good job.

Valto:
3000w 100k
4000w 160k
6000w 215k

Are these normal ratings or peak powers?

bassdow:
Those are Peak Power ratings. If they quote Normal Ratings, it would appear small which is bad marketing Wise.

There are inverters that could be 5kva but actual power is 3.5kva but if advertised as 3.5kva, you go leave am go find the wan wey big.

adrusa:
It is misleading and false marketing to advertise inverters using their peak powers which can only be sustained for very few seconds. @Valto should advertise their normal ratings.

AyobamiOluwole:
Let me understand something.

If a product description of an inverter produced and written by a white man reads 3Kva, I should tell you it’s actually 2kva? Like I (a normal person who happened to be selling inverters) needs to test all the different brands and specs of all the inverters myself to be able to tell you that it’s actually a 2kva, etc?

Is that what you mean?

adrusa:
You are wrong. Normally inverters have nominal power ratings and several peak power ratings. A nominal power rating is what the inverter can handle normally and indefinitely. If an inverter is rated 3000W, it should be able to carry 3000W indefinitely. Peak power rating can vary by how long the peak power can last before the inverter trips. A 3000W inverter may have a peak power of 6000W which can only last for 5s before the inverter trips. It may be able to output 4000W for longer time like 10s or 15s. The peak rating is needed because of inductive loads like AC and Freezers that require high power when they are first started before settling down to their normal power consumption.

I have a 3.6KW Outback Inverter that can do 3.6KW and slightly more. I have also had hybrid inverters that can do up to their ratings.

You may have been confused by two things.

1. Power factor (PF) which creates a difference between apparent power and real power. Apparent power is measured in KVA while real power is measured in KW. When power factor is 1, both KVA and KW are the same. When power factor is less than 1, KW is KVA * PF. A 5KVA inverter with a PF of 1 is 5KW. If the PF is 0.7, the inverter rating will be 5*0.7 or 3.5KW.

2. The second problem is fraud or deliberate mis-labelling by marketers especially the Alaba guys who put higher stickers on lower specced equipment.

If you will allow @valto to answer my question, you will see that he does not need to test the inverters to know their real ratings because they are actually indicated in their specifications. The Chinese quote the peak powers as a form of marketing gimmicks and fraud, but they will indicate in small letters the real powers of the inverter.

Topper33:
Guys, Please what are your take on this:

So i have been following this tread for some time and from poplular recommendations to others , I was convinced and then I ordered and received a 3.2kwh battery from a buider on this forum. The delivery was fast, no delays. Although the set did not come with any accessories, no baterries cable etc . This was as stated by the builder. ....(only the battery box in a plastic build with a small bms screen and a button). All as advertised. So no issues there. This setup cost #550k (delivery inclusive). All i got in addition was the waybill receipt

The truth is, my friend who ordered for a 26.5v(100Ah) itel 2.5kwh battery, received theirs yesterday:
To my supprise, the itel battery Bank alone was 2.5 to 3 times heavier than mine, the setup was built in a solid steel housing case, has 3 internet communication ports, and 3 other advanced looking ports. Came with ALL the comm ports cables, also came with two 20 mm solid +/- battery cables , 3 year warrenty card, thick steel wall brackets, metallic wall screws, some addtional bolts and nuts and many more.
And all this cost #481k (including delivery fee).

Now I know why people crave the itel battery pack.

Although I have to say I over expected much for mine, but the person i bought mine from did not give me the kind of attention(as a first time customer as i would have wanted) the response sometimes was quite slow (had to literally push for any information with response coming anything it comes) no step by step on how to do much. I had to ask about value to set for bulk and float etc, Had to push and ask or most times google some stuff on my own. (I am not saying the seller did anything wrong o) but sincerly I dont think I may patronise the person in the future.I like my business partners to be approacheable irrespective of the value or amount involved in the trade......(my choice)

So, the itel on the other had virtually a full hands on manual that explains EVERYTHING you can do, clearly defined warranty card and many more quality of life stuffs you know.....

Although, I for one became a bit skeptical about the build i received (when i recall the itel heavy weight and quality) but everytime i checked the jk bms app, i showed all the cells adds up to 3.2kwh (see image). Even still, my mind still tells me I should have gone with the Itel due to its solid built, wall handing capability, solid customer and aftersales support, the quality of work and support it has.
(I thought going for "3.2kwh" was better than "2.5kwh" so i had to stop my initial itel order for the local build).

Its well sha


Forgive me for my long epistle...Just wanted to air my thoughts man.

Thanks Guys

Azzamann:
Please I need help.
Has anyone here patronised Henry Batteries?
The contact lady on WhatsApp is insisting that payment be made before I can go pickup from the warehouse off Oba Akran.
Is this legit? Because I dey fear o

Cc. Bassdow, Penuelseun, osayuwamwen, OCTAVO, Dam5reey1, odimbannamdi, dollarnaira, HeavenlyBang, Trippledots, fuckboys, ceejay80s

Please can anyone vouch for them? I dey road already.

iraybuju:
Even if you waist your time and money go the warehouse the wrong time when Chinese Dey sleep then you go waist your money go back to house because them must approve the payment for head office for china then approve manager to release your goods. Your question should be how good the battery is, it’s very cheap and affordable but quality uncor if to say you Dey near me I for say make you come carry my own bought it last month.

Unfaized:
Go on tiktok, search Yadea Lagos. Or Yadea Nigeria.

XPaul:
I am currently using just one battery on the inverter. The other one is bad bad and I plan to sell them as scrap.
