Saipro:
Run out before morning? That shouldn't be happening. My 5pm to 8am consumption varies between 1.8kWh and 2.8kWh depending on usage of fans and the number of them running. At that, I still run a 1kW kettle for 30 - 60 minutes almost every morning. Never gone below 50%, that I can recall. That's an open-circuit voltage of roughly 48.4V (estimate) and around 48.0V - 48.2V with an idling 3kW inverter.

For you ...

48V (nominal system rating) * 200Ah (bank Ah capacity) * 0.5 (anticipated DoD) * 0.85 (estimated inverter inefficiency)
= 4,080Wh bank capacity till you reach 50% DoD

If load estimates are right, (4,080 - 2,450)Wh = 1,630Wh to spare.
Granted that the CC and inverter have some self-consumption, your reserve to 50% DoD would be lesser. Unless they have quite high self-consumption (I know my PowerStar 3kW consumes nearly 100W when idling in a closed circuit and about 10W in standby mode), you shoudn't be exceeding 50% DoD, much less running out of power. Look for some rogue consumption somewhere in your system (backfeeding of panels in the dark, AVR left on, parasitic loads, etc). Give feedback. Let other members contribute their experience and data as well.

Thanks again Saipro.
I do not have the manual that came with the inverter so I really can't tell what the self-consumption is. I think I may have to plan to add another string of 200aH batteries. That na another project
I really want to have 1 day autonomy without touching my Gen. I want to make the best use of the investment and enjoy it to the last.
Moreso, I will look at replacing my bulbs with the the 6W or 8w bulbs.

Thinking of batteries, I understand its not good to mix batteries. I want to go for Trojan batteries. If I have another string of 4 x 12v trojan batteries connected in parallel with existing string, is it OK?
For the guys dealing on Trojan (Frank and co) do you have flexible payment options?

I may also want to change the SUKAM inverter to PRAG and have the SUKAM as standby. The SUKAM gives me little worries. Each time I switch it on, it trips off by itself and comes back on. That happens like 3 times before it gets stable. Sometimes hours later when everything is running, it also trips off and on. Does anyone has that experience yet?
Sometime in the past when it overcharged my batteries, It was already doing this trip off thing. I took it to Symba and complained all these. They told me its all sorted. But it turns out that only the overcharging issue was fixed as the tripping continued. I have changed the DC switch at the back of the inverter yet it continues. So I need the equivalent PRAG inverter to 3.5KVA SUKAM.

Not forgetting AC and DC protection from lightening. Oh boy, this thing no easy ooo...

Saipro:
Impressive figures. 49V isn't bad at all. Even with minimal loads, there's a voltage drop. When boiling water on the kettle in the mornings, I get as low as 47.8V over a 30 minute to 1 hour period, if usage was extensive overnight. When I tak the loads off, I get about 48.x to 49.x (occassionally returns to 50V when I switch off the inverter off just to take readings). That's for a system that at times runs nearly 2 weeks off-grid when NEPA feels "generous".

Are you off-grid? If not, what is your night time total energy consumption like? I think you're in equilibrum. The first rule of RE is energy conservation, not energy generation. Though difficult, try cutting down on energy consumption. LED TVs CFE/LED bulbs, fans instead of A/C when dark, etc

For the record, your system is similarly sized with mine. 48V 225Ah battery bank, 240W PV panels x 9.
As advised, you can up your battery bank but please let's have your post-5pm to pre 8-am energy consumption data (the sum not breakdown).

Hi Saipro,
Thanks for your contribution. I've swapped most of the 'swappable' devices to the energy saving ones. Bulbs, tvs etc.

For the energy consumption at night:
5pm - 11pm = 2060WH
11pm - 8am = 390WH

Total (5pm - 8am) = 2450W

I already multiplied the loads(W) with hours of run. But like I said, I have to power off by 11pm or 12 midnight else the inverter will run out before morning

chris81964:
9645 / 48 = 200.9375 is what your useage is. I multiply by two to give me that magical 50% depth of discharge.
Based on what you wrote I assumed you had a 48 V inverter.
You will need four more batteries of the same capacity to get your 400 AH.

Maybe we should take it from the beginning. What is the voltage of your inverter? I understood 48 is that incorrect? 4 batteries in series gives you 48 V assuming 12 Volts each. The AH still remains at 200.

If you buy 4 more batteries connect them in series and then parallel them. You do that by connecting the positive of one bank to the positive of the other. And then repeat the same for the negative.

Thanks Chris.

You are right. Its a 48v, 3.5KV SUKAM inverter. 4 x 12 x 200ah batteries connected in series. I understand the part of having another string of 4 batteries and connect in series to double capacity. I was just asking the possibility of upgrading in bits due to cost.

I.e if I buy 2 batteries now, it wont be enough to have a 48v string from it. So is it possible I take one the new batteries and parallel one of the running batteries now and do same with a second battery another running battery, till am able to get another 2 batteries to have a whole 48v string?

What will be the implication of doing that please?

I just don't to risk loosing another battery because once am not around, the people at home dont care if the battery voltage drops. I had a situation where I came home and the inverter was beeping already!!! They were still rocking the TV and other appliances

chris81964:
Your production is good. However your battery bank is undersized. Your Production will be limited by your use. You should have a battery bank that is double your load hours. At 48 V your battery AH useage is 200.9
You are covered during the day time. Your production on day two was higher because your batteries had been drawn down a bit.

Thanks Chris.

Previously, from my calculation I was getting 189AH as battery requirement. I was making a mistake obviously. I have 251AH as battery capacity from my recalculation. Is that correct?

If yes, how could I possibly upgrade? Can I just get two batteries of same size/age and parallel them with two existing? i.e 2 batteries in parallel + another 2 batteries parallel, then connect the 2 in series (24v) and add the other 2 in series (now 48v).

That is total of 6 batteries.

Will it work or do I have to get entirely new string of 12 x 200aH x 4 and parallel the new string with the existing string?

Team,
I'm trying to figure out if my installation is giving optimal output. I tried reading the meter but I need help to decipher. I have:

10 solar panels now (average of 250W each).
4 x 12v x 200ah Batteries (48v)
Total Load x Hours = 9645WH (load = 1535W; Individual devices have different hours of run)

I get these reading on my Morning Star Controller (45A) from the logging data
Today, Battery 3490wh; battery 68.5ah
Day (-1), Battery 4560wh; battery 85ah
Day (-2), Battery 5260wh; battery 103.6ah
Day (-3), Battery 4520wh; battery 83.5ah

Then I also have these on the front reading: 1613kwh; 73112ahT; 3649kwhT; 31908ah

On a good day my battery goes beyond 49v just before midnight and I have to shut it down. Are my installation undersized for the load?

donmajor2:
Plenty regards to Richmon74 for the supply of 4 260W Solarworld mono panels.

I also got solar mounting rails/brackets from c0ogumo of solardepotng.

After collating the main components from the gurus of this great forum, I decided to try my hands on all I have been reading on the sideline.

The result has been impressive. The batteries reach float charge so quickly that I am beginning to think of increasing the number batteries to store the enormous energy pumped out by the 4 Solarworld panels.

This is my very first attempt at solar energy work.

As a newbie, I decided to post some images to open room for corrections.

Many thanks to all members of this thread.

Impressive. Nice one

I Haven't Get Any Help Yet But For The Catholic Church, Is Far From Us Here And If I Should Go There, How Are They Going To Authenticate My Story Since My Churbh Is Different. Brother, Please If There Is A Way U Can Assist A Poor Man Pls.

I do sympathise with you. I am a Catholic and member of St. Vincent De Paul. The society mandate is to assist anyone created by God whether you are a Christian of another church or Muslim or any other.

But based on experience and rules we do not give out based on sentiments. That is why I referred you to a close-by Catholic Church as I cannot authenticate the claims myself.

Hope you understand my standpoint. I will gladly work towards giving you immediate help once. ......

Trash...........

What part of the write up did you consider trash. Can you trash the points raised here one after the other?

OK. I believe you are already getting help from here already.
If not I will expect you to put some efforts to locate a Catholic Church close-by and then revert
Peace of the Lord be with you.

OP, how do we authenticate your story. Go to the Catholic Church within your area now. Ask of St. Vincent De Paul society. Explain your problem. Whatever they say, get back to me.
PM me to relate via email.
If they authenticate your story then be sure of help asap

locodemy:
Thank you for understanding my own pattern.i am sure people who trade everyday makes alot of money than i do but the risk is high.some will end the year loosing almost all the profits they made within the year while others who knows the game pulls out when they sight danger and the zombies keep on trading at the current low prices while the thing keep falling and they have one word that strenghtens them(the best time to buy).last week FBN was at 5.45 and people saw it as the best time to buy.today the price is #4.90 and who knows if it may be #4.50 tomorrow.so these are the risks i calculated before choosing my stock trading strategy.i know most people here are brokers and can never like my pattern because i refuse to enrich their pocket but mine.

I like your trading strategy. I think it's fair to share it here though different people will expectedly see it from different perspectives.

In all honesty, all stocks I've bought within December to January periods I've profited from. The ones I incurred losses are one I bought after March / April. This year's losses na die

Your strategy isn't different from Aks strategy. I maybe wrong, but I recall when he advised around mid year that people should hold on till late year end. (I usually like his posts).

Anyways, am gonna adopt your strategy. But like you mentioned knowing the right price to enter is key. So do let us (your followers) know when you feel it's right to enter, and the stock u recommend.

As usual, I understand that no one, except me, is responsible for any losses (or gains) I may incur by following any advice or recommendations here.

pipu are just too fast to make comments here, did u guys does read the news article at all?
ok, this is what happened, in that scenario, the dead guy stole the accused aluminium roofing sheet, i.e the dead guy is a thief, (who knows maybe na 1 notorious and deadly thief sef), and unluckily for the dead guy, he was caught or something, who knows maybe its in d process, maybe the punishment meted on him was too much or something, and he passed on, and as we know nija police, they charged the man whose item was stolen (the accused) to court, but for the judge to be a reasonable fellow set him free and discard the case, which should really be the right thing in a sane environment. NICE JUDGMENT

Even after reading your comments, many still didn't understand that the guy's SIN was catching and beating the Thief who eventually died.

The judge really delivered a Good judgment.

1. Transcorp

2. CCNN

4. Dangote Cement

5. FBNH

GTI 5 Weekly Stock Pick - 250515 - https://theanalystng.com/news/27216.html

1. Transcorp retains the top spot on this week’s GTI 5. The Conglomerates giant is well positioned in the economy to benefit from any boom. The Company reported a strong top line growth of 119.6% in its recently published FY 2014 report and despite a steep 52.5% decline in net income for the review period, our long term outlook on the company is still very positive

2. CCNN climbs to the second spot this week. The Company has managed to translate marginal growth in revenue to strong double digit bottom-line improvement by cutting down distribution/ admin expenses by as high as 35% in Q3 2014. We expect this trend to continue in Q4. The bearish trend currently prevailing in the market has opened up a strong entry position into the stock for investors who want to benefit from the impressive 2014 performance of the Company

3. Julius Berger retains the third spot this week. The leading construction company in Nigeria enjoys a large chunk of the construction contracts of the Federal government, and even though we expect a slowdown in awarding of new contracts due to the elections, we expect the company to record moderate performances in FY 2015. The infrastructure inadequacies in Nigeria is a major incentive to hold the stock of Julius Berger for the medium to long term

4. Dangote Cement claims the fourth spot on the GTI 5 for this week. The company controls about 80% of the cement market in Nigeria and has made major in routes into other African countries. The recent announcement of a slash in cement price as well as the tightening margins due to the tax element on some of its production lines which previously enjoyed the 5year moratorium for expansion projects (including the economic parameters which have generally affected the market) has increased the stocks volatility in the recent past. However, our long term estimates for the firm are still realizable for its share market dominance.

5. FBNH retains the fifth spot on the chat this week, claiming the fifth spot. FBNH currently trades at a price to book value multiple of about 1 and we consider this as a very attractive window for short term investing.

Happy birthday to a wonnderful contributor on this thread. LLNP.

I don't have any thought of dealing on Oando for now. FCMB is the way to go, i stated this in the morning, WATCH OUT!!!

Do you still stronlgy believe FCMB is the way to go?

I monitored everything from morning till now......Its very funny market,but has a lot of potentials.....I sold some batches of FBNH that I bought at 8.5 today and I made a remarkable profit.....I hope to sell the rest after next week....Its good to use NSE website to monitor the prices directly.......

Please can you share the NSE link again? Someone already posted it though but coudnt find the page it was posted.
Thanks

Meanwhile, Access bank here i come..

PROSHARE stocks for the week: http://www.proshareng.com/news/26740/Investdata-Weekly-Stock-Picks-Proshare

1. Oando
2. INTERNATIONAL BREWERIES PLC. (INTBREW)
3. NATIONAL SALT CO. NIGERIA PLC (NASCON)
4. UNITED CAPITAL PLC (UBCAP)

Meanwhile, sold off Oando @ 33% profit. Waiting for pullback to re-enter again

@AKS, MyJoy Et al, your take on Proshare picks please....

Aks:
You can take this to the bank: Oando sell off will continue till it reaches N13+ also Transcorp Sell off will continue till it reaches N2.80+. The major arm of Heirs holdings bringing in the revenue is the Hotel business which is now a seperate entity. BTW, Oando re-entry @ anything close to N14 won't be a bad option

I pity those guys taking myjoy08 advice hook, line and sinker. I doubt if this guy invest @ all on NSE. All he does is to recommend BUY, BUY, BUYYYYYYYYYYY which is a no brainer to me

The day you hinted of the Bears coming back when the Bull was raging, I was about placing order for this TRANSCORP but seeing your posts, I thought it was logical and held on. Next trading day, all the bears entered market. You really showed you had experience in this market. Thanks!
In one of my posts back, I mentioned that I bought some stocks and made over 20% profit based on MYJOY advice (and even CHIBUIK). So its really a nice expereince from everyone.

I will continue to look out for your posts. I will however recommend that you don't (Should I say attack) others based on their comments or advice. No one knows it all. The fact that MYJOY recommendation, as at the time it was made, didn't lead to profit now does not take away the fact that he has been helpful.

You all are my mentors in this NSEMPA - Hope I will make money enough also this year from the stock market..

Pls what is the best way to deposit funds in meritrade,I just transferred funds to d Zenith account but it's not credited yet online

Once you make payment, send an email to contact@meristem.com informing them of the bank you paid in and the amount. Hopefully you will be using the same email you used to register with them. If not endeavour to tell them your name and email

Cheers

Meristem still down. But if you want to excute any mandate, just send them a mail - contact@meristemng.com
I send them mine via email and they worked on it within 3 minutes (Not bad)

I've entered the Transcrop Bus and Flourmill too (As usual, not a recommendation - The choice is always yours)

@House - CCNN dividend of 35k is it a good omen or not?
