l mean the energy saving bulbs, especially the 9 &14 watts thank you

omotech:
l welcome everybody to the new year both gurus and novices. Happy New year where can someone get all this stuff

LasgidyPort:
Alright sir. Thank you so much. So what is the price range in Naija for those premium brand inverters (1.5KVA)?

LasgidyPort:
Thank you once again. The algorithm part is too technical for me oh. How do I identify the charge algorithm?


This are the specs I copied from Prag's site on their 2KVA:

Model 2KVA
Rated Capacity 2000VA
Rated Power 1400W
Transformer C.R.G.O
Interface LED graphic
Display Status working & loading & battery
Input
Voltage 140~275 Vac
Frequency 45~65 Hz

Charge Current Max. 10A/15A/20A optional
Cooling System Yes

The part I highlighted, is that the charge algorithm?

LasgidyPort:
I also read diverse opinions on nairaland, and a lot of people believe Prag newest additions have been improved on. Abeg help

sarutobie:
That is an African civet for Pete sake! This animal has been all but wiped out in this part of the world..when they are all gone what then do we do? Start hunting humans probably.

LasgidyPort:
Pls recommend a good inverter battery for a novice who has read everything you guys have been posting and is even more confused.

Pharyn:
The Inverter and Disconnect Box (175A) are on the wall while the Central Stab (met on site, along with previous wiring) is sitting on the floor.
The 8 Batteries ( US L16E XC2 6V) are on the other side of the wall outside, sitting on a metal rack, laid with plywood.
A flexible weatherproof cover would be fabricated to shield the batteries from environment, yet allow hydrogen breathing.

The Client wants the remote to be with the Inverter and the Remote cable is so long to make the board look cluttered. I would still repack it well.

50mm cables were used all throughout (Inverter-Fuse-Battery connection) including battery interconnecting cables.
Remains DC Grounding.

Special thanks to the House, especially the people that are always ready to answer Qs (richmon74, Abunafiu, solardepotng.com c0ogumo). Thanks for your support.

OP, when did you get married to your wife?

I am single and yet i was able to decode the meaning of that dish served to you!

Your inlaws are smart! They just sent a message across to you via that plate!

Take a look at the way it was arranged.....

The Plate signifies your MARRIAGE.

See the beautiful patterns on the plate to show that your marriage is a beautiful thing on the outside but it is the experiences it comes with which is the content and edibles in it and HOW YOU REACT to those contents that matter.

Now here we go......

The Coconut that was arranged in the circle which is sweet to eat signifies the lovely times you will have at the earlier and initial times in the marriage.

Then after that, the Bitter-kola in the inner section signifies bitter and unpleasant experiences you will get to experience after the earlier times in the marriage due to quarrels, misunderstanding, pressure etc. You can see that they are in different varieties meaning that your marital problems will come in different forms but will have one thing in common (The will all be a BITTER EXPERIENCE FOR YOU)

But if you are able to persevere and endure by eating all the bitter Kola RIGHT ROUND without giving up, you will then come back to the Coconut which is in the middle of the plate which signifies sweetness! Eating that last piece in the middle will erase all the traces of the bitter taste of the Kolas and you will never remember you even ate anything bitter in the first place!

That is what it SIGNIFIES!

Oya....you must surrender your wife to me as punishment for not decoding this! (Only if she is beautiful o) #JustKidding

You're right, and that is the conventional wisdom, but this is being put up to debate:

Since this is an experiment, we are prepared to make real-world measurements and realign as needed. Will keep you posted.

jamp:
hello people. we want to install solar lights in our farm. presently we use generator to power the bulbs. we have a total of 27-30 bulbs(energy bulbs) in the farm. please we need honest people to give us price for the cost of getting solar panels,charge contoller,inverter,batteries etc.

please send text to 08175286459 with the details. text only.

thank you

Barezzi:
Seems its affecting my daily average harvest...
Might have to pour some water on the panels.

samnaija:
thnks for response the battery bank comprises of (6 batteries) each 2v 500ah connected in series to give 12v 500ah.60amps cc and about (6 panels 250 watts ) thnks alot.

KOLAPO3:
I am also having some challenges with my mercury 2.4 inverter and 2 genus batteries 200ah. I purchased the system 3months ago
Since phcn has been better over the last 3 months in my area I have enjoyed the set up.
But now things are back to a bad state.i have a lot of questions. It takes almost 24hrs to get the batteries charge to full.
Eg 7 hours of charge (5hrs generator 2 Nepa)
Only lasted for 3hrs with just 2 ceiling of fans
I am really confused
Please help

adrusa:
As to solar support, it will depend on how much NEPA do you get per day. What SOC/Voltage do you get to in a typical morning after overnight use. It is presumed that solar will charge your battery for about 4-5hrs on good sunny days. You can calculate how much solar you will need based on SOC/Voltage of your battery in the morning and what current (in ampere) will you need to put your battery back to full charge in about 5 hours.

Saipro:
You're quite right the likelihood of a battery exploding from overchaging AND internal shorts are quite small (about 10 - 20%) of all battery explosions. Most are due to ignition from an external spark. That data is from countries which keep statistics. I have no clue of local statistics. Indeed, asides from one and only one incident, all battery explosions I have witnessed are from external sparks. I periodically overcharged dying car batteries to revive them WHILE MONITORING BOTH SG AND TEMPERATURE. I still tried reviving one two weeks ago over a period of two days. I had about 30% success but it came to life sufficiently to be of short-term use. One should be safe doing that. However ......

In as much as it might seem a funny comment, those who've experienced explosions (I have a friend with a scarred lower face and upper torso) will tell you it's a life altering experience not to be taken lightly. Remember, most of the things posted here are not for the sake of the pros but for the amateurs.

kiekie1:
Thanks... Images can be shared since its basically for sales reason ...mind you I never copied it from you, what point are you actually tryna make here tho, I can send you enough stock pictures from various warehouses if you need cos there is no patent right governing product pics and sharing for resales sake.! Weekend regards!

Saipro:
Indeed. You're quite correct. However, above all outcomes you might seek, bear your own health and safety in mind. The batteries have one foot in the grave, not you.

Saipro:
There are lots of reasons postulated for the positive/negative terminal batteries failing earlier but the truth is, many at times, for no discernably obvious reason, they simply fail. Just like that.

I have great faith in desulphators as I have used a few with testimonies (Abunafiu is aware of this) but the issue of equalizing sealed lead acid batteries/AGM batteries ......
.... at best, one would be killing the batteries faster (shortened lifespan/cycle life). Note that the risk of explosions become real when equalizing AGM batteries. A suitable alternative might be holding the absorb (or bulk voltage for those which have different+higher bulk voltage) for many hours. Both safe and effective.

Oops, I've said more than intended

abunafiu:
Thank sir@ chris81964. The inverters in question are the popular indian brands we all know. The battery used are 200ah of the same indian brand name.
Yes most of these clients deplete their bank up to 100% dod. The issue now is most of the inverters have battery low voltage alarm usually at 11.0V and wt this level of discharge a significant number cycle life is lost. How come its only one battery that suffers this ill fate?

most installers are faced with same problem. let's discuss
