JUO:
congratulations big Bros on your upgrade . I visited during installation. Thanks for being there for us all

@ GeorgeD

do a YouTube clip from start to finish. you may hit 1m downloads who knows.

ur Aircon go hear am! or do cold room business & smile to bank.

GeorgeD1:
south side completed

keep it up big bros. the house remains grateful for ur leading roles in DIY.

can someone shed more light on

"PRINTED SOLAR STRIPS"
It expected to replace the present poly & mono solar panels considering price and performance in low light conditions (including at night)

present cost/price is $7 per square meter.
market entry is in 18months.

can gurus speak on this emerging trend which will soon be embraced by millions of electricity starved worldwide.

PRINTED SOLAR STRIPS

@ Chris (Dr. Solar)
one chance batteries 1-4 is quite interesting. keep up the good work.

Oga Nisol

I just discovered the good work you did several months ago

https://www.nairaland.com/1794647/design-build-48v-40a-mppt#24385844

any update on performance of the device?

in case we need to patronize you in the house.

Thanks!

nisol:
There are lots of brilliant minds in Nigeria, unfortunately "man must wack" before any other thing else.
If we had our priorities right as a nation, innovators would have enough time to research and produce quality made in Nigeria goods.

bigrovar:
Problem is when it develops a fault and then you are stuck because very few technician knows how to fix those things. Name brand is non tested durability is in question. Besides most convintional fridge are getting more and more efficient as long as you have your system is well sized u will be fine.

good point sir
I was authoritatively informed it can be converted to conventional fridge/freezer

but-then what a waste of resources just because of low wattage efficiency.

Saipro:
Cycling loads (especially thermostat regulated ones) are really difficult to put an energy estimate figure on because they might consume their max nameplate rating till the thermostat kicks in (whenever that is). Then there's the surge to deal with each time they start up again.

I have a freezer which consumes roughly 360W on startup and 300W a few minutes later. From then on, consumption is highly dependent on how cool the interior is. Somehow, the more items frozen in it, the less energy consumed (seems somewhat logical), right up until the thermostat kicks in.

And manufacturers often list nameplate values for ideal operating conditions - oftentimes a far departure from real world conditions.

True talk.

I came across this nameless fridge/freezer
reading 72w only. But I went back there with A/C watt meter & had a reading of 102w wen compressor kicked..

maybe some enthusiast will check model online for nameplate or http://www.google.com.ng/url?q=http://www.sy-beier.com/Product/3980245831.html&sa=U&ved=0ahUKEwiYs_S9z4DUAhWNalAKHUD3CSsQFggLMAA&sig2=W5p8GZW-GZXyWxDouaRGkA&usg=AFQjCNH1qncdoshfOPMXm9iSanf0LCbPrw

I bought and installed their 2kva/24v inverter.
Noiseless unlike other midrange products that the fan turns on & off often.
Performance has been good too

Down side is that the finished work isn't crisps as labels are glued to casing and detaches after a while.
E.g. input voltage label e.t.c

nice reading ur views. I hope dey improve. thank you for believing in nija. we get there sooner than we think.

let's buy nija panels instead of Indian or chinko or any other.

my next upgrade will revolves round nija (at least 30% local content)

imagine Australia has 1.2m households using solar, Nigeria can do better with local content.

cheers.

kiekie1:
Good morning Sir,no its not same with tubular batteries I supplied to you few years ago.. Its the normal SMF vrla battery.. Coscharis paused a while in the importation of tubular batteries due to some factors best known to them... Luminous has same 220a 12v tubular , Genus has 200a tubular & few uncommon brands in Alaba etc ...

sir Frankie, Are d Genus 200A tubulars same design on ur YouTube video?

Are u still using dem, pls let us know its performance against d giant trojan.

I want to go flooded wen funds are available.

DMerciful:
Its been awesome. connected it to my inverter and charge with the inverter or cc. i have a battery switch that allows me to select either the lithium bank, the flooded battery bank or both. I mostly use both combine in order to reduced the charging current going into the lithium. Highly recomended.

10yrs of off grid guaranteed
10yrs of saving diesel/petrol money.
10yrs of saving estimated billing.

I foresee you building 5 star hotel soon with ur huge savings from wise investment in solar.

thumb up my brother. daz nija spirit.

sensisosu:
Boss thank you for your input.. please I would like to know where I can buy the solar rack with adjustable legs?


Thank you boss

some installers can be frustrating. they make people hate solar after huge investment.

and again some customers may claim too wise resulting to " penny wise pound foolish" and not agree with professional advise.

which ever,
I commend ur determination in making ur solar do-able rather enjoyable. ur burning desire to perfect ur setup is making u overlook simple but crucial questions put to you on the thread.
go back read them point by point & provide ur observation as they are, don't coverup mistakes we all make mistakes. before gurus loose interest in attending to u. we have tens & tens of gurus reading & not commenting, maybe u will have their sympathy to redeem ur setup.

in the meantime ur on the right path to R/E.

DMerciful:
Bought the 48v mppt controller, opened it and did not see the characteristics inductor(toroidal coils), i returned it sharpaly to the seller . their inverter algorithm is nice though

thanks great scholar.

I hope to get more review from the thread. hoping dat we need to buy nija & grow our own solar industry with a view of forcing down prices over time, say 5yrs time.

instead of chasing dollar and transferring chunk of our wealth to China

BUY NIJA PRODUCTS

please I need information on AUXANO SOLAR Products and price

has anyone had experience with their hybrid inverter or mppt CC or their actual pv rating ?

Do they have auxano ba3 too?

do they have extended warranty on their products?

thanks!

JUO:
please disconnect the 13amp from your connection is not a good practice, 100amps are available

OK. oga JUO

I Neva know 100A A/C watt meter is in market.

I will contact u soon for shipment.
much thanks.

earthrealm:
yup, laid to rest!.
a common denominator with kiekie, inspite of all the other complaints, is that he makes effort to deliver promptly, and no case of fraud recorded against him, hv transacted wih him a couple of times

this watt meter/kill a watt, seems the 15amp variant isnt in the market?...all i see is 13amp type.
am looking for led bulbs, not panels...seen some on konga 7w , 5w etc...but not bright enough for me...want to use them as security/outside light...prefarablly mounted on top of the fence

tx bro
you're right
my watt meters are rated 13amps but I have practically pushed over 15amps tru one of dem without problems. I advice u immediately change follow-come ba3 wen u get a new one.

surprisingly, standards are abused in Nigerian market. I have tested those LED bulbs and found that they are NOT tru. they are fraudulently rated. 3w is actually 5.5w & dat 7 watt is close to 12w.

so bare in mind these erroneous or misleading information on LEDs in d market.

cheers!

earthrealm:
what type of charge controller are you using? and what are the preset chrging voltages.
when i was using morning star cc, once there is phcn, the morning star charging output will reduce drastically [prolly cos the inverter charging voltage was higher than the cc's voltage.------ who knows, long time ago it happened, and wasnt so knowledgeable]
now i use epsolar with charge voltage set at 15v, it never happens again, with phcn..battery bank will be charged at optimum rates simultaneously.

hope you know the 3.5kva inverter cant charge your bank properly, thus the solar panels should be your primary charging source [hope you used the correct charging voltage setting in your CC].
SOME BAtts in ur bank are unhealthey, try and isolate the bad ones, load test, use a hydrometer to test the sg of the batts, and ensure you rectify and equalize your bank frequently. you may consider changing out the trojan if you confirm its irredeembale

some inverters like full voltage 220v, anything below 170v, and they will stop charging and switch to bad mode...either get a 5kva stab...or buy a 10/15kva central stab for the whole house

@the fullriver batt issue, by stating 50k as his selling price, kiekie is indirectly telling us that we should always haggle& price him like market women, selling crayfish. seems we expected much more noble standards from him , i dont like haggling , but my few interactions with kiekie confirmed to me that he likes /is iused to haggling,
cu0gumuo / richmond to mention a few dont use this haggling route, they go straigth to the point price....seasoned professionals

@kiekie i price your 250w panel u listed 27k, i need 6 units, my nos is in my signature, call me if game

I have painfully observed recent discus regarding kiekie1

it is good to raise & settle issues here. I subjectively think the fullriver ba3 @ 50k be laid to rest.

Have had customer-seller relation wit Sir Frankie almost on monthly basis & he delivers as per agreement.

with cash deposits to him, i have not heard issues of fraud or 419 case. if prices are not mutually ok, trade cannot occur , it does not mean one should paint one bad when the market is flooded with alternatives.
please let's by-gone be gone, and not post childish talk anymore and build cooperation across Nigeria through solar.

@barezi @Dmerciful
much thanks. I appreciate u all. I will do dat along upgrade am hoping to do soon.

can someone study my installation & advice me. in a bit to cut out MATE 2 & monitor my setup, the wiring is getting scaring and a kind of substation.

I need advice on how to tidy it up professionally.

I have 2 AC watt meter for monitoring consumption from inverter. the 2 AC watt meters runs my flat on two separate wiring; one to my DB for the whole house & d 2nd for basic load of LEDs, LCD+decorder, Rechargeable fans.

also, My DC meters ( thanks to oga JUO) monitors my batteries readings/current drawn from them and the other monitors my PV performance against CC Readings

I am kind of worried it is not professional. any advice please?

kiekie1:
Nope Mr Efuro, he only re-posted my update he saw on another thread for needed clarification .. Hope you doing great.. Cheers !

seen!

sensisosu:
Hello house,

I have a 3.5kva Sukham inverter system with a setup of 8 pieces 250w mono panels, 60amps mppt charge controller and 4 200amps batteries

The issue I am currently having right now are:

My solar panels are positioned in a way that after 1pm my panels aren't getting enough sun light due to the position of My house(the panels are placed on the roof of my house)

I have a problem with a Trojan battery as it discharges faster than the remaining 3 batteries

My inverter usually goes off at 2am in the midnight with minimal or no load on the system

When I'm on nepa inverter cuts off when there is drop in voltage..

I would like my honorable members on this thread to enlighten on how to get the best out of my systems..

Thank you all and I will greatly appreciate your opinion

old boy you have an enviable solar setup!
I know some members will fume being too quick to offer my chip of little advice or help.
just imagine, national grid has dipped low again, imagine again the built up anger with non solar users. As solar enthusiast & DIY, i know solar-is-able therefore it is my joy to offer my piece of advice within the limit of my experience, of course it may be considered not optimal showing reasons for other DIY to learn.

so Oga sensisosu,
what i garnered from previous discus on flooded ba3 particularly Trojan, I don't think you have a serious problem. I believe that ba3 has caused ur bank to drain too quickly because itself has not been properly charged by inverter or panels. so consider doing limited load & equalization charge of 15.5v for about four hours for about a week am sure u will see signs of recovery.

on your panels not receiving enough sunlight. I discovered I am guilty of same during installation of my setup too by schematicaly laying Panels vertically instead of horizontally. laying horizontally extends surface area to more sun while it travels from east to west. like guru dmerciful & other mentioned. the angle of elevation can also work wonders.

I submit that you don't tamper with ur sulkam please.

thanks

In January u offered that same CC@ 170k when dollar was $1-N500
Now $1-N360 ur offering it @ 250k

Haba! We should take things easy now? Or am I missing something?

babaegun:
So, few days ago, I upgraded my setup from the old 24 volts , 4 solar panel setup.

Now i have a car port with 12 nos 250 W Solar Panels (mixture of felicity and my-home with almost similar configuration). The car port can accommodate 15 panels Maximum (by just tweaking the holes in pipes), 80A Fangpusun Mppt Charge Controller, Mate 2, 48V Battery (4 Quanta batteries connected in series), and 5kva - 48V Felicity Inverter.

The only item missing is the Monitoring System which i need to complete but I can access the readings up to 128 days on the Charge controller. Need to brace the car port too. Interestingly, the highest generation so far recorded 8.4kWH in a cloudy day and I've been off grid for like 3 weeks(24/7) because the transformer in my area packed up.

I think its a good way to start for a beginner like me, right?

Solar is addictive, I feel happy seeing people deriving joy from upgrades.
Seat back & enjoy ur sweat. Every kobo spend is well spent.

Awaiting Solar Depot price list for 2nd quarter 2017 on the platform.

Kindly paste your current list please.

Of couse, ur 20A breaker is sufficient and will even protect or CC.

Mathmatically maximum for ur setup would be around 16.66A @ 2x2 remember it a 200w PV

A =200W/24V =8.33A.

Also imagine extra amps your CC will have to convert from excess voltage in addition to 16.66A

My point is that if I were u. I will opt for higher rating to allow me expand along with it. Solar is addictive , you will soon find out that u need more panels etc.

Cheers!

therealMcCain:
Thanks Sir

1. You said 2x2, 20A

Was I suppose to go for a higher breaker rating? The max of my CC is 30A

I saw 50A breaker but I felt that will be useless there cos of my CC amp limit

the parameters for the panels are

Voc-43.2v
Isc-6.24A
Vmax-34.8v
Imax-4.9A

With a 2x2 config what Current will I be getting? Will it be more than or up to 20A?

Before the panels were taken up, the meter reading from the 4 panels were around 36v each.

2. On the issue of breaker to cutoff feedback, the only breaker i have is the ones in the DB

So far, 2 sockets doesn't trip the inverter

@ McCain

I find Addresses to ur questions appropriate within the limit if my DIY.
I don't do solar installation for a living, all my contributions to the forum is purely what I gained from the house/forum & personal DIY efforts expressing that solar is do able.

I USE THIS OPPORTUNITY TO THANK ALL MEMBERS IN HOUSE in making sure R/E get roots Nigeria.
I say thank you all sellers in the house for honest services. Many of whom I had dealings with and many more I will contact for their services.

Now Oga RealMcCain
I am happy u've chosen ur balcony after putting necessary measures in place.

2x2, 20amps (well maybe 4 now daz wot u want), 16mm are splendid. Also ur ba3 @ rest 13v is nice.

About 2 AH indicated by cc means ur ba3 are floating & do not need to draw more harvest from ur PVs.

On ur inverter, I think it is back feeding itself due to ur faulty sockets. Remember u said it comes on wen switched off if u slightly insert loads.
But a crude way to check of ur inverter is not back feeding is to remove output loads to ur DB & connect sometin like frezer to the back of the inverter for about 20mins, observe its performance & beeping. Ur will know if back feeding as affected it or a factory defect.

Don't u have appropraite breakers to cut off back feeding before being detected by ur inverter ?

Anyway I appeal to gurus in the house with similar teething problems to contribute.

Cheers! Solar rules.

Thanks!

Ferdiwar:
That could be measurement error from the CC or watt meter as they are all prone to some % of errors.

I appreciate you for finding time to cross check cable-voltage-drop.
Thank you sir.
Findings are noted!

pranil:
A 10 mm2 cable will loose 4.6 mv per amp per meter How much is the current ?. if the shunt of the meter is 200 MV then 0.2 drop is in meter itself .see attached. Meanwhile 0.5 v is 2 % difference which is well within tolerance level of measuring instruments ( normally they are class 5 ) if you want accurate readings you need class one meter like fluke Multi meter or hight quality meter ( e g. BMV 700 e) panel meter .

earthrealm:
1 yard is about 3ft, are you serious or the yard is a figure of speech?, there shudnt be any loss if its 3ft long .

At least, so says the watt meter & CC readings.
Always 0.5v difference.

The ba3 are wired @ 24v series x 3 parallels. No special loop to equalise the three 12v nodes.

JUO:
do you mean you use 10mm from battery to cc? Nice inverter you have there. I have been looking for something similar that I can switch off the charger completely and use only solar to charge. Anyone with one?

10mm
On the manual of the inverter, Indians claimed it has double coil transformer. I wonder if it is true. But I trust it to charge my 6 100A batteries as it has not failed me with its manual settings for ba3 type & normal or high amps charging.

Sorry about pix quality of cable as I have to bend down under d ba3
