It's a forum where people share knowledge and experience... No one knows it all...

Asking people to Shut up ahaha...

There are three kinds of ppl on this thread
those i would ignore; those i would argue with and learn from and those i would tell to outrightly
shut up !!!
Go figure !!!

chuchwhite:
As u can see .. mine is working like i told u earlier .. below re pictures for u to see ..

Seems SWIFT is up to some game!
And your pics alone doesn't show concrete evidence of it browsing . . .

Do a youtube video

mcTrinity:
honestly speaking, some people shouldn't be in this forum...

that someone uses solar system doesn't really make the person mature.

you read some response and you discover that If this were to be a face to face scenario, punches will actually fly.

Please, let's be mature and maintain the integrity of this forum
Thanks

You wouldnt even dare be half the man that I am
So shut up please !!!
I am literally begging you to please do!

^^ Well, your own school of thought, I might consider . .

My school of thought says its archaic (pre - Edison age) to follow your school of thought . .

No wonder we got this far and couldn't even produce pencils . . .

Alessandro Volta would spanked a lot of y'all on this forum . . .

I repeat . . Voltage is a loose term; EMF is a more specific term

. . .

You're talking trash . . .When I was in school, and I remember if a lecturer threw a question across . . .
some "smart-ass" would lift a definition or theory verbatim from the internet without understanding how stuffs work . . .
Your case is akin to such . . . Verily, verily, I say unto you . . . You're far from a being a Physicist . . .

Court !!!!

DMerciful:
Please lets maintain some level of decorum. we are all here to learn...nobody is a repository of knowledge!

I am calm, just spicing it up, that is !

And before you argue again . . . I used the term e.m.f (electro motive force) .. a measurement of the potential difference

between two points in a circuit. The S.I.unit of e.m.f is Volts ( losely called voltage) . . .

SO when people say, "measure the voltage of the battery" . . they are actually wrong . . .

it's more like saying . . "measure the meters of your house to mine" instead of "measure the distance . . . "

since meter is a unit.

It is more scientific to say, "measure the e.m.f across the battery's terminal"

But we have become used to saying Voltage . . so we stuck with it.

I could go on and on. . . I don't do Google's copy n paste here !!!

dapsyra:
What I stated is physics!

A potentiometer inside a voltmeter is used as a variable resistor to calibrate the accuracy of the displayed value. That is one of the three uses of a potentiometer as stated in my earlier post. The fact remains that a potentiometer cannot and does not measure potential difference. It is essentially a resistor with a variable centre tap.

There are many laymen in this forum, so it is important to give accurate information in order not to lead them astray.

You are talking rubbish . . like i said you are quoting online or textbook Physics for us.
I am quoting real life applications for you.
Draw your two ears and hold them tight, i repeat . .
A potientiometer can be used to measure potential difference or electromotive force, put it as you want in a circuit.

If you are a true science student, then you would know that a potentiometer is preferred than a voltmeter when it comes to
measuring voltage or more precisely, emf / Why?

When a voltmeter is connected, the circuit is closed, and internal resistance comes into play. Little current is drawn, so it tampers with the accuracy of the readings.

On the other hand, a potentiometer is an open-circuit measurement, no current is drawn, so it's more accurate for measuring emf or terminal voltage. it is also more sensitive than a voltmeter.

SO when next I tell you that a potentiometer is used to measure voltage, just keep shut and don't argue.

Yes, it could be used for other purposes like you mentioned too; but don't tell me it doesn't measure !

dapsyra:
A potentiometer is not used for measuring potential difference, a voltmeter is used for that. A potentiometer is either an adjustable voltage divider, variable resistor or rheostat depending on how it's three legs are connected in the circuit. It can be used to adjust voltage setpoints upwards/downwards and also for accuracy calibration depending on the circuit design.

You are quoting textbook definition;
i am giving you the basics of what a potentiometer does . . .
What is the job of a potentiometer inside a voltmeter ?

NiyiOmoIyunade:
Sorry if I used the wrong English.

There is SOMETHING inside the Souer charger, I am told you can TURN that SOMETHING LEFT or RIGHT to adjust the absorb voltage setpoint - similar to how you adjust the PRAG/MustPower inverter voltage setpoint by turning a dial/knob to select different charging algorithms for different battery types except that the PRAG/MustPower adjustment is external but you have to open up the Souer to make the adjustment.

As you know, different inverters or charge equipment have different internal setups - To be very clear, I was speaking of how to adjust a very specific charger brand called Souer and not generalizing on how inverter voltage setpoints or charge algorithms may be adjusted

Maybe the very high end souer models would have this feature/facility . . .
but the pretty cheap ones, like you mentioned, do not . . cos I have had one for more than 4 years now
and have dismantled and arranged it, more times than I can count.

chuchwhite:
My guy calm down am not miss informing him .. i said am using mine and it works without the 3gig .. have exhausted the 3gig and it works for me .. will show u picture later tonight when it time for unlimited browsing... mind u this is the second time am using it nd it works for me .. check below my screenshot aswell.. will also post another once it starts browsing again later tonight..

Just called customer care now and they said; NO; i have to top up . . I wonder why !

NiyiOmoIyunade:
Dear both,

. . .let me muddy the water by saying I know of a chinco smart charger called Souer which costs less than 20k and can also output 25 - 30amps charging current . The charger has a reliable cutoff to float mode and the default absorb voltage is 14.8volts - the charger can be opened up and the potentiometer adjusted for lower or higher absorb voltage as required for a specific battery chemistry.

recipe for disaster . . . the last time i checked a potentiometer can only be used for measuring potential difference (voltage in layman's term) ; (hence the name: "potentio - meter" )across a circuit . . . adjusting the potentiometer will only increase or decrease the accuracy of the measurement . . . that's all. this is done to calibrate the meter when it is losing accuracy.
It cannot be used to reduce the voltage setpoint at which the charger goes into absorb or float . . if it were that easy . .
we could see ourselves opening up our inverters and adjusting the potentiometers in them . .
The voltage setpoints are embedded into the electronic chips/motherboards as CPU instructions;
that's why many ppl shy away from such chargers .. cos they kill batteries over time.

jarkbauer:
I intend to combine it with NEPA light.

Do not account for NEPA . . . while doing your audit; to avoid stories that touch,

If grid power comes along the way, that's a plus . . if it fails; you won't be affected.

chuchwhite:
It works when ur 3gig is exhausted.. i use it at the moment.. have exhausted the 3gig so i only browse when the unlimited night browsing kicks in

pls don't misinform him . . it doesn't work . . .

check attached pics;

call customer care if you are in doubt.

Dam5reey:
He might need upto 1200w

You have not considered usage during the day time..

Oga cool down n read what I posted again . .

Thats just the basics . . if you wish to power some loads during the day; therefore you would need to add more panels;
depending on power requirement.

just because u wanna contradict me, u ddnt bother to read

if i wozz u slap ehn

Dam5reey:
Thanks boss..

You're welcome . .

jarkbauer:
I currently have a 1.5KVA 24volts inverter
2 200amps batteries.

I want to add solar array.

Please Can someone tell me what I need if I want to add solar.

Thanks.

Assuming you only discharge your batteries to 50% everynight;
you would be consuming just about 2.4KwH
And you need at least 800Watts of panel power to recharge the battery back
in about 4 hours sunlight . . .
I mentioned 800 Watts because it would be downplayed to about 600W x 4 hrs= 2.4kwH . .

Thats just the basics . . if you wish to power some loads during the day; therefore you would need to add more panels;
depending on power requirement.

Dam5reey:
Does it work when you exhaust the 3GB 24 hours Data. ?

No it won't . .
You have to top up with at least 1GB @ 1000 . . .

Feshizzy:
Thank you kind sir for you swift response,
Batteries are AGM and the inverter have it settings to the letter, the current charge has 3 profile, low/medium/high and it is on the medium setting.
Forgive my ignorance,
But has there been known cases of inverter having failed algorithm and fixed?

Regards,
EF

Yes, a lot of times !

Just for the hell of it, you say you use AGM batteries, yeah?

What are your absorb and float voltage setpoints?

battery hissing indicates overcharge n gassing
inverter charging algorith has failed and is now overcharging battery
or somebody tampered with the charge settings or profile or you got a different class of battery
one of these options is the answer

Dam5reey:
So you do bench test too...

Thought you have a general rule that all panels cannot produce more than 77% of the rated capacity real life, even Canadian panels..

My nigga; rules can be bent; especially when large sums of "owo" is involved

DMerciful:
Did a review sometime ago but posted in bits as the autobot was banning me whenever I post for like 3days and even deleted the posts. Anyways, lithium ion phosphate is what they say it is....high longevity,immunned to sulphation and memory effects, high DOD. Expensive in the short term but extremely cheap in the long run

Thanks so much . .

Lithium , oya activate !!!

DMerciful:
What controller do you use?

Isn'it it obvious?
EPever iTracer series

DMerciful:
Sorry Wi-Fi ebox. Bluetooth is finished.
Goes about 50meters

Let me know when you have the bluetooth again ..
i already have a dedicated wifi at home;
using the wifi ebox requires me disconnecting from the home server just to check the stats
and connecting back

too much wahala lol

DMerciful:
Go lithium and forget about strict charging and discharging rules, DOD, uncharged state,high current drain etc..just use, lool. Still cheaper even in the medium term

You still haven't given us a geek's review of the Lithium config.
it's what has been keeping most of us off it for some time . .; especially me . .
I'd love to see it working 1st hand . . for the cost involved, i need to cross all t's and dots all the i's

@Makavele
Was the test done about same time? Cos Sun angle is important as well as SOC of battery. I use sunshine and I get up-to 80% sometimes

Yes sir, the test were done at the same time . . .
I had to borrow the same charge controller from a friend, identical to me, in age and specs.
And test was carried out on the same battery bank; same load
Same panel configuration . . and I was monitoring . .
Even if there were to be a disparity; it should be within plus or minus 10% . .
But 55% to about 80% margin was too wide . . .
Trust me, I repeated the tests again some other day; and i got about 55% to 70%
No matter what I did, the Sunshine panels would not output past 55% of its peak power
What a shame !!!

olagunju2000:
Thanks Niyi.

I still have challenges achieving full charge everyday. In most cases, i get past bulk charging to Absorption phase around 4pm everyday except yesterday that i got to floating stage because we had grid supply BY MISTAKE!!!

I try to ensure i don't go below 55% DOD as I am practically living off grid. We only get power supply whenever there is a major fault

A quick question, i am planning to increase my panels so as to cover for my day use and also enough to fully charge the battery for the night. What brand of panel are you using? I am considering 300w Joysolar or may be Sunshine. Is there any other reasonably priced panels i could explore?

Thanks

Sunshine not bad
But I got more results from Flames as against sunshine !!
zee; take note

Sunshine gave me just about 55% panel power;
Flames gave me about 80% power . . same installation environment; same weather !!

^^ he needs a 12V inverter that can output a decent 50A or more to get those batteries in good shape . . .

Too much going in there; less efficiency. If it were to be a 24V setup, only needs about 25A or so

But his battery amount is lacking . . .

That's why i prefer 12V batteries straight up.

By the time you start stacking 2V batteries to make 24V; mehn . . where is the space sef ?

bigrovar:
I use microwave, energy efficiency does not mean live like a monk. Juo uses electric Iron. Energy efficiency is about doing more with less.. If you have the money and AC is a priority then by all means but at least save energy in other areas. For me and I know many do not have the luxury here.......

Too much epistle .. we r both saying the same thing which is:

some people cannot stay without e.g. an A/C overnight and if they have deep pockets;
they can decide to buy 300 10000Ah batteries if they like( if such a battery exist) . . .

Meanwhile, some will manage a fan overnight;
and are good with just 1 unit of 200Ah battery or 2.

Some do not need that large bank but because they have deep pockets
and what to show off; they will go for it.

So its a personal choice . . . there are no hard and fast rules.
I can decide to use the microwave on just 1 battery of 100Ah, how long? 10mins maximum to heat food

But when I want to use something like air conditioning overnight for like 8-10 hours;
I therefore need a huge bank . . .

ALso, some people have a standard; 15W bulbs or nothing . . . they cannot adjust to using 6W bulbs
They know its cheaper to save energy, but they be like" "Give me the bill to have electricity 24/7 here"

Even if its 100W bulbs each in the house; they don't care . . Just give them the bill, for that 100W bulb to stay on 24/7.

We all know its good to be energy efficient,
but back to square one, a matter of choice and personal preference . . especially when it comes to the cost/price to pay.

Try "vox" it should go as well.

Vox is for voice over lte . . it won't work !
