Please advice before i do something wrong!

48VDC/800AH battery and load of 3000W(extimated) running on inverter.(24hours on weekends and about 12hours on weekdays)


Below is my own configuration:
24pcs of 255W solarworld panel and 2pcs of 80A outback CC.


I intend to install as follows:
12 panels(3-strings and 4 parallel) per 80A outback CC giving me 3060W from my panels at 100%- set A (this should give me about 63A @48v)
12 panels(3-strings and 4 parallel) per 80A outback CC giving me 3060W from my panels at 100%- set B (this should give me about 63A @48v)
Connect both sets A nd B from the Charge Controller through separate breakers to the 800AH/48VDC battery system.

Since my batteries total AH is 800AH, it means i would want to charge at 10%+ rated (i.e 80A charging current) which am sure to get from my 2 charge controllers PLUS extra current for my load during day time.

QUESTIONS (Put into consideration the batteries are fixed, other components can be adjusted)
AM I on the right path?
Is using the 2 charge controllers justifiable?
Are the nos of panels OK for this system?
What is the minimum and maximum configuration i can use in this situation?
Considering cost, if i am to use just one CC, how many panels would you recommend?
If am to totally go off grid, what config would be the best?


Thanks as i await your professional response.

Good Job Richmond74. More adrenalin to your system.

i cant see the pix clearly but here is my advice. Check the data sheet or google it. The timer should have the power contacts and the contacts for the function based on different time rate for delays which you are going to connect to your alarm.

Thanks !

Hello Prof richmon74,

Is this system an off-grid system? If it is, then for a hybrid system, how many panel will you recommend since power from the utility will compensate for charging too(at night).

Good work you are doing here! I ll love to visit you soon.

More grease!

I stopped by a client's house at Unity road, Lekki today to check the performance of his system and I was impressed by the harvest. This client lives off grid as they are yet to complete transformer installation in that area. The only appliance he is not using are the A/Cs. Every other appliance including Fridge, freezer, washing machine and watter pump runs on the solar system.

The system configuration is:
3060W (12x 255W) Solarworld Solar panels
8x L16 Trojan Flooded batteries
4kw PRAG Inverter.

The 3060w solarworld panels was able to output 3458W as you can see in the picture below which is higher than the rated output of the solar panels. The log also confirmed that this system delivers up to 16kwh of energy daily.

These go a long way to confirm that solarworld solar panels efficiency is second to none. Also remember that the installation must be done professionally also in order to get this efficiency.

Stop littering your roofs with junks in the name of solar panels and also get a profesional installation.

Hi business genuis,
I have to complete a business transaction by transferring money to india. Instead of the normal BIC and Routing No, i was given IFSC code by the supplier. We have been on this issue for a while now, my bank (GTB) seems not to understand. Pls, who has done business using this code before? Pls advice.
Thankx

I subscribed for the Blackberry service N1000 (BBC to 21600). my money was not deducted and NO SMS was received. i repeated this several times for two days and nothing happened. with annoyance, i used my air time for calls. after exhausting my airtime, i loaded mtn recharge for normal calls but the voice prompt says "i do not have enough airtime'. i bought extra airtime and its still the same response. i bought more and its still the same. I CAN NOT CALL NEITHER CAN I SEND SMS.
WHATS THE PROBLEM?

Thanks, I really appreciate your response
Best Regards

thanks yawa and pgon for the concern.

am aware of akeebah and kickstart and all that. one thing i have realised with we web developers is "we like tampering with our own personal website all the time". if we are not changing hosting, we change the design, we change content, we add this , we add that.

my point is i was just tired of the old website. i wanted something fresh but just too lazy to start typing contents. i can say the only important thing from the old website i needed was the text content. i didnt want to bother with all those akeebah and stuffs. at first, all i did was just backup my db and upload to the new one, then disabled all the old stuffs that came with it i needed no more,installed new ones before the yawa gas.

besides that, i changed webhost, i got tired of and decided to try . I successfully moved all my clients without hazzle. .

Anyway, my new site is up and running 70% completed with the new design. I simply deleted the old installation and started afresh. And it paid off cos new ideas were flowing and the time spent was worth it.


Thanks again

Thanks yawa n pgon .
D site was initially designed about 3 yrs ago using joomla 1.5 . I copied d database, and saved. This year I changed webhosting n installed joomla 2.5. I transferred d database, installed latest softwares for modules and changed to new templates. So, wat could hv gone wrong? I hv checked d article properties- no problem.

hi, am presently working on a new site using joomla. the article editing is proving stubborn. am thinking probably i have enabled/disabled something unknowingly.
here are the problems:
cant upload image in content
cant insert a page break
cant insert a table
cant insert a readmore.
once i do all the above and save, it goes back to "as it was".

i have done the following:
changed template
changed browser
chose default,extended and advanced in the editor tinymice plugin
i have created fresh articles.

still no effect.

any possible solution?

Thanks. It actually ddnt work on d remote, d reason I askd u b4. One of the other method which I presume is changing the configuration file should work though I hvnt tried it. Is d one u hv different frm the one at doc.joomla.org?
Share it here pls so that everyone can benefit or u can share d link.
Thanks

guru
Is this applicable online too from the server?
THANKS

thanks pgon, u just answered my question

THANKS ALL, AM AWARE OF ALL ABOVE MENTIONED. THE FEAR OF FAILING IS MY HEADACHE.
MEANWHILE AS AT THE TIME OF LOADING THE NEW SITE, WHAT DOMAIN DO U USE TO ACCESS IT SINCE YOU HAVE NOT CHANGED THE DNS?

hello gurus, i want to transfer my clients website from my old hosting to new hosting. my headache is:
i have created new hosting account for all the websites but i didnt want to change the dns yet.
i have joomla installed on all the old sites which i needed to transfer using akeeba or any other good one.
since i have not changed the DNS, HOW DO I ACCESS THE NEW WEBSITES SINCE THE DOMAIN IS STILL POINTING TO THE OLD HOSTING.

APART FROM AKEEBA, WHICH OTHER GOOD TOOL CAN I USE TO TRANSFER?
THANKS

Reseller club seems okay. @vbhost, ur package looks tempting. U seems nt to have online payment in ur system. I can always integrate that into mine. anybody here against vbhost reseller package/uptime etc

Thanks all for the response. I ll check the reseller club. I mentioned I dnt want nig reseller cos i ve bn using one for some years now and I need to expand my biz. What would I get frm nig reseller when I know if u go down, I go down. I ve also used sultanhost in d past, hostgator dnt have what I want,ipage am not okay, resellerspanel so confused, resellerrocket nigeria wahala. And d list goes on

Pls GURUS , RECOMMEND a good reseller webhosting offering unlimited SPACE AND BANDWIDTH. ALSO WITH WHMC AND DOMAIN REG. I dont want Nigerian hosting offering reseller hosting. thanks

ok. anybody else?
if nira cannot meet up to standard, then why promoting .ng tld.

IS THAT THE RESON. I WANT TECHNICAL SOLUTION.

hello gurus,i have bn studying all my clients site and i have noticed something. the sites i did with .ng tld domains(.com.ng, .edu.ng etc) fail to connect at times while the general ones(.com, .net, info etc) connects DURING THESAME PERIOD.

its surprising becos i have them all using the same hosting.

WHAT COULD BE WRONG?
ANYONE WITH A SIMILAR CHALLENGE?

try and create a fb page for your biz first.add conrent and oromote your services.its free. with that, you can request your friends to like the page; and from there, your friend's friends sees it, like it, and it becomes viral. "it spreads fast".

but if need to spend money, u can use d create advert application and customise it for some particular sets of audience, location, age category,country etc

airtel too slow. i need to unlock the modem. any info?

thanks to u all. its just funny.i uploaded just the way ve bn doing all my sites.
