135k for 685w. Bought in Kaduna.

EndiaSami:
Greetings

Please what's the price like. Or dealer contact will be appreciated

Thank you

I've never used any of those but the dealer confirmed to me that it's a good brand. I settled for it after a mere physical assessment of the panels, they looked sturdy - although not the standard test for quality but I couldn't wait for when next he would have jinko in stock.

chadbasin:
Can it be compared with Longi, Jinko?

It was getting to the 4th bar before now....but this has been fixed by changing some of the battery settings on the inverter.

mctfopt:
Was it getting to the 4th bar before this? Or was it forever on this 3rd bar.

This fixed the problem. I had already configured the battery type to FeL. All I did was just to change the bulk charge voltage from 28 to 28.4v, floating charge voltage from 27 to 28v, discharge cut off from 22 to 22.4v (as specified in the battery's manual), and restarted the setup. The 4th bar was not only restored but fully charged before 12pm.
Thanks.

bassdow:
To accurately debug this ya matter, one needs be physically present BUT we could try.

Check to ensure the battery settings are properly configured. That's certainly where the issue is coming from. If the current config has voltage less than the battery's full charge, then the inverter certainly would stop charging the moment it gets there thinking it's full.

Also be sure this issue isn't a One time thing.

Ensure batteryType is Lithium or Li

or if using custom settings (mostly called USER), then set things manually

Bulk / absorptionVoltage: 28.4v

Float chargeVoltage: 26.8v to 27.0v

Low DC cut off voltage: 23.5v

So far so good.

chadbasin:
Please how good are these Runergy panels, someone has been trying to convince me to buy them.
Anyone?

Good evening house,
It's been almost two weeks now that I noticed that my battery charges and stops at the 3rd bar, not getting to the 4th. My inverter type is Genus Hi-Flo 4.2kVA 24V paired with a 3kwh luxwatt lithium battery, and three 685w bifacial Runergy panels.
Has anyone had a similar experience and how was it resolved?

Coincidentally I'm using the Genus Hi-Flo 4.2kVA 24V paired with a 3kwh luxwatt battery, the fan is always on but not to the extent it could disturb my sleep, where it's mounted isn't up to 10 feet away from the wall it shares with the room I sleep once in a while. The only time the fan becomes very noisy is when the sun's intensity increases suddenly (not all the time) and also when I decide to do a quick off-grid ironing (pressing iron is about 2000w).
The noise isn't even my concern anyways but my total setup's output - the highest PV reading I've ever seen is 1.1kw even during peak sun hours. I use three 685w bifacial Runergy panels mounted on the roof.
My questions are:
1. Is this output good enough even though I hardly overwork the system, highest load percentage is 7% when my fridge is on?
2. Will there be any difference if the panels are mounted on a carport since they are bifacial?

bassdow:
see eh, don't have much experience with luxSun brand BUT just once i encountered it, not really worth it. If funds are low, better off with Haisic or SAKO or Genus hybrid inverters going by the budget you told me.

Have installed Genus Hi-Flo 4.2kVA 24V about 3 times and even prefer it to Haisic.

Also instead of 3kva, go for 4.2kva that way you rarely would hit 70% load which means longer service life of ya inverter. 3 freezers constantly coming OFF and ON no be moimoi + you still wan use pumping machine.

By convention, when a computer's or inverter's fan stays ON for long and is even loud, means it's over working. And lots of cheap inverters fit dey show 20% load YET their Fan go dey blow like where Fat man wey pursue pregnant goat dey breath. luxSun inverters are like that even when almost no load.

Also be very very careful buying USEd inverters from market. The miracles wey dey happen no be here.

Often I recommend 48v system for inverters above 3.5kva, BUT going by economic realities, nothing spoil at 4.2kva of 24v so long you don't load it much.

Let's not be mistaken, my review ain't about Fan noise BUT perceived quality + durability.


But let's hear from more experienced pals in here. Possibly installers, engineers and end users share their experience dem forget to program am to off.

Have you been able to get this resolved?

Topper33:
Hello My people

Please I discovered that my Inverter (itel hybrid 3.6kva) no longer charges from the grid. When ever I turn on the breaker, I get error 3 and the inverter stops. From the manual, it states the error is Bus Voltage Low

This occurs only when I turn on the grid breaker while attempting to charge. Charging from the panel is working fine

Please can this be fixed or where can I take it to for repairs... Would appreciate feedback based on your experience.... Thanks

A similar scenario played out when the elderly electrician that handled my solar installation invited a young guy who is supposedly a solar installer too, to lend a helping hand. At a point during the inverter connection, I overheard the young guy telling the man to do a connection "anyhow" that it would still work but the elderly man cautioned him that he doesn't do his jobs anyhow so as to avoid future issues with his clients.

bassdow:
I suggested someone get a radioNic (those that repairs electronics such as Tv) and I specifically asked He looks for the much elderly ones and when He asked why I said so, I told him because they are the Ones more likely to be good at their work.

My generation mostly are after quick wealth than experience.

Also this wire coding issue is really a thing as I have faced it numerous times.

This is noted.
Half-baked and lazy artisans are more in number nowadays than the good ones. Some would even wish you pay them without doing the job...the get-rich-quick syndrome.

FEGEITOK:
For Everyone on Solar/Inverter: The Electrician Who Found the Fault Nobody Else Would

Most of us on this thread have spent good money on inverters, batteries and panels. But here is the hard truth: a solar or inverter setup is only as safe and as efficient as the wiring and earthing behind it. A perfect inverter on a bad installation will still frustrate you, waste your load, and in the worst case, shock somebody.

I am posting this because I found a man in Abuja who actually understands that, and I am staking my reputation on him.

First, who he is

His name is Daniel. He is Trade Test 1, 2 and 3 certified, and NABTEB certified. He is a qualified tradesman, not a "boy who learned small wiring."

What he can do:


Electrical drawings and design
Full house and office wiring (done to code, not to convenience)
Fault tracing and troubleshooting (this is where most installers run away)
Thunder arrestor / lightning arrestor installation
Earthing installation and remediation


If it is electricity related, and that includes the mains side of your solar setup, he is your man.

Why the solar crowd should care

Here is exactly the kind of problem he solved for me, and I suspect some of you are quietly living with something similar.

Whenever mains power tripped, my inverter would keep ramping up and running at about 50 percent load for no reason I could explain. On top of that, whoever originally wired the house had used a single colour of wire for everything, live, neutral and earth, which is a violation of basic standards and a nightmare to diagnose.

I did the obvious first step and installed a brand new earth rod and earthing connections, assuming the old earth was the culprit. It was not, at least not the way I thought.

Then I noticed something frightening: the fridge, freezer, microwave and cooker were all shocking to the touch. But only when power came from the mains. On inverter power, zero shock. That clue turned out to be everything.

When I told him, he did not give excuses. He said, "Let me come and confirm." He tested the live, neutral and earth at the affected outlet, then went to the distribution board and tested the common earth, common neutral and common live. Every single one lit up on the tester, which should never happen.

His first instinct was to check every outlet in the house, tedious as that would be. Then he stopped and said, "There is a better way." He decided to isolate the fault at the DB level instead. We separated each earth connection one by one and tested, until the earth stopped lighting up. That pinned the fault to one circuit: an AC switch and a looped wall socket in the guest room.

Here is the part that impressed me. He climbed into the ceiling and asked me to call out from the ground which room he was standing over. I said the guest room. He traced the wires to the exact wall, came down, went straight to that socket, opened it, and there it was. Because the house was wired in one colour, whoever did the original job had bridged the live to the earth without knowing it. That is why testing live, neutral and earth all gave the same reading, and that is why my appliances were live to the touch.

Once he fixed it, I switched the breaker between the AC input and the inverter back on, and the mysterious ramp-up in consumption was gone. Problem solved, completely. My inverter finally behaves the way it should.

Why this matters for your setup

That single bridged wire could have killed someone, and it was quietly stressing my inverter every day. If your system is behaving strangely, tripping, ramping up, appliances tingling to the touch, the problem is very often not the inverter itself. It is the wiring and earthing feeding it.

Daniel is the kind of person who will actually trace it instead of telling you to buy a bigger inverter.

He told me plainly that most electricians will happily show up for a new wiring job, but the moment you say "I have a maintenance and troubleshooting issue," they vanish and give every excuse in the book. He does not.

My appeal to you

Someone this good does not deserve to be sitting without work. Please give him jobs and support him. He is Abuja based.

This is not a sponsored post. I am simply an over-satisfied client who owes him one.

And if he ever gives you any issue at all, come back to this thread and raise it with me directly, and I will intervene.

This must be a storey building I guess. If yes, your engineer is just shying away from the task of plastering the under deck. The cost of plastering and screeding (although plain and without design) won't be as much as using Pop/polystyrene.

Ndyoo:
Good morning house,

Please I have a quick question because it doesn't make sense to me. My Engineer is telling me that's cheaper to do polystyrene/Pop on the ceiling than just plastering the ceiling. Note it is a residential building.

I look forward to hear from you.

NB: Because his charge for the internal plastering was so expensive only for me to realize later that he won't be doing it and it wasn't specified on his quote that the ceiling won't be done. I told him I want the living room and dining only to be Pop in order to reduce cost.

The weather has been rainy and cloudy most times today in my location. My inverter reading is as shown in the image.
What should be the performance rating of my system consisting of a 3 pieces 685w panels connected in series to a 4.2kva inverter?

Hi Professionals in the house,
These are the specification labels of what I'm starting my solar system with pending when I would upgrade. Please help to analyse and any advice would be greatly appreciated.

Yeah, I'm starting with 3 pieces of 620w panels.

Thanks.

Ezimuoh:
If its a single 620W panel, it will not work o, you need 2 or 3 of it to be able to get up to required PV Voltage for the MPPT to pick

Penuelseun:
They are not compatible as the input current of the 620w solar panel is higher than what the inverter can take

Thanks for this.
How about using 4.2kva inverter whose max input current is about 18A with the 620w panel? My battery storage capacity is 3kwh.

Hello Professionals in the house,
I planned using 620w rated panels as earlier advised here. Please, help to compare these two spec labels of the inverter and panels respectively whether they are compatible.

Good evening house,
I have a 3kwh lithium battery I intend to use with the hybrid inverter whose product label's image is shown. I'm looking at starting with 4 pieces of 550w panels, what do you advise? What difference would it make if it were 620w panels?

henrixx:
brand new sealed itel 3kva inverter for sale. unused and unopened....340k

brand new unused 620w jinko bifacial panels x3 ....125k each

brand new breakers and distribution boxes also available for sale

What's the reason for selling the unopened and unused inverter?
Would have considered buying it but the location.

Thanks for this.
I intend using tubular batteries for now, which brand and capacity is recommended?

justasitis:
The wattage you indicated for the Refrigerator is not quite clear, but 1.2kw/24hrs = 50W/hr

Total loads = 310W/hr *6, that’s approximately 2kwh
You can go for a 1.5KVA 12V Hybrid Inverter + 4Kwh LifePo4 Battery, 450W Jinko panel *3 or 4.

Hello house,
I would be very grateful if anyone here can help give the sizes of the various components required to set up a solar system using the info below. Any other good battery type asides lithium should be recommended.
TV - 70W - 6hrs
Decoder - 50W - 6hrs
Led lights - 40W - 6hrs
Phone - 30W - 6hrs
Refrigerator - 1.2kWh/24hrs - 6hrs
Fan - 70W - 6hrs

Thanks.

Your feeling ain't wrong, this quote is for a normal in situ POP casting and installation. I'm surprised that the food/water the labourers will eat/drink and even the clothes they'll wear during the period of working for you are not included in the quote. If not, why would the work tools every POP installer should have be also included in the quote? You will know what to do after the professional POP guys here make their comments.

Celepope:
Hello House,
This is a quote I got for a gypsum board ceiling. I see it as being weird with the amount of bags of PoP in the quote. I was expecting to see profiles and some other materials needed for Gypsum board. The person looking over the site don’t want me to have the direct contact of the person that drew this quote (Person that will do it) I feel they want to go ahead to do a PoP instead of a Gypsum ceiling being that I’m not around and I might not know what was done. Is there a way I can get a rough estimate of materials needed for Gypsum board ceiling considering the square meter (519) involved so that I can confront them with the materials that will be needed?.

Professionals in the house kindly weigh in on this:
I visited a location recently and I noticed something about the houses there:
The older houses look sturdier and without traces of wall dampness but on most of the recent builds (a friend's own inclusive), you notice the walls are being attacked by different levels of dampness even though measures such as higher ground clearance and DPM installation were taken to curb such.
I began to wonder: on the recent builds, asides poor workmanship, could the materials especially cement being produced nowadays also lacking in quality? The house I visited was built in the early 2000s and the landlord confirmed that most of the houses built around the same period didn't do DPC (German floors) and DPCs weren't installed either.

What are the factors to be considered if one wants to connect to a borehole who is about 200m away? Please note that the borehole is already in use and sited in a residential property.
Thank you.

Ongoing screeding and regal paint application in ondo.

Compliments of the season to you, Gbadexy.
How can an internal screeded wall which was painted with emulsion paint be restored to have this glossy feel/appearance?

michlins:
yes it's possible but the height shouldn't exceed 4ft. Use 2½ and above

Hi Michlins,
Just revisisted this your response: I guess the 4ft height is a typo error. Also, is 2½ the thickness or the height/width of the sides? Please refer to the attached image.
Thanks.

rossovu:
Professionals please I need advice

Are there painters that can produce quality paints?

Someone introduced me to a painter that said he can produce paint that will match the quality of princess paint. He charged me 17k per drum.

I'm just imagining the cost of iron rods and other materials that would be involved in the new concrete beam... The project owner's financial muscle really strong o. I commot cap for am. Anyway, what needs to be done should be done in order to have the best outcome.
Well-done Engr!

spyder880:
Good afternoon my people, we should have been done with this foundation, but it looks like this foundation height will need to be adjusted upwards. Our plan is to raise the foundation height by adding a line of blocks to this existing top concrete beam, then top the new height with a new concrete beam before we now cast the foundation DPC.

I will update you all on how we are doing this.

Dennis3D:
Final leveling commenced already from the back of the building.

We are now doing a Total of 14 coaches excluding the decking beam which will make it 15 coaches before the decking slab.

This is our standard. And it gives us a very nice headroom for POP finishing when the time comes.

What measures are you going to put in place to prevent under-deck POP ceiling collapse as we have been reading in the news lately?

spyder880:
Already on site since morning, doing our work here................

Great job as usual.......................

Which town in Nigeria is this building situated?
