Pls whats is the apn for ntel.. cos i got a call fron ntel cc asking why i havent subbed in a while and also they gave me 1week free browsing .. but i out the sim and only whatsapp goes at times .. browsing doesnt work .. i set the apn to ntel but i wanna be sure i did the right thing

ntel it is !!!

if you tell them, they don't need huge battery bank to enjoy 24/7 light it looks as if you don't know what you are saying. Imagine one person generating 18kwh in a 3-4 bed room apartment. What for, are you selling energy? Energy conservation is the only solution

It depends on individual preferences though ; for example; some people cannot stay with air conditioning . . .
hence more batteries and/or solar panels.
While some can do with a ceiling/standing fan overnight . . .

The most important thing is, if you won't be powering heavy appliances;
then there is no need for an insane battery and/or solar bank.

Except you wanna show off; at which point it becomes a thing of either foolishness or wasteful spending.

Dam5reey:
Before buying any electronic. I look for power ratings and sellers will be wondering why...

I never used to care about power ratings .. until I went green . . .

The learning curve is steep; but once you adjust; it's fun . . .

Dam5reey:
Obviously it's not 3watt bulbs but energy efficient 9watt type...

The first step when going into solar is power audit... You miscalculate you will waste money...

I have dozens of this in my house . .

Recently, I had to replace all the bulbs in my house with the 5W cool-white LED bulbs . . . 45 in all

(minus 14 x 3W spotlights)

Thats 45 X 5 watts (max) = 225W if they are turned on concurrently

Cos I came to realize it is cheaper to save energy than it is to generate it.

Dam5reey:
If your system is pure solar (off grid), then 140 + 150 watt panels will damage the battery due to insufficient charge current... Practically you can only get 50-60AH from your panels on a good day


For hybrid system like mine, I do have power most of the time so my 220 Watts panel is just a supplement... To keep my battery voltage High during the day... I run my inverter 24hours/7day

For 200ah do not load more than 100- 120watts
Recommended solar for off grid is 600watts...

I do see some seller misleading people buy selling a system with 100Ah battery with 130watts panel and tell you you will have 24 hours light...

Of course, you will have more than 24 hours light sef; sheybi na just connect one 3W bulb . . dazall

Bloody demeanor !!!

It is dropping during charging with the Load on as well.

This is what I am saying . .
The panel and/or charge controller isn't working . . . and you think it is working . . .
so you connect the load . . . . the battery keeps dropping volts until it gets flat . .
But if the panel and/or controller is working, then battery is bad . . replace it
So isolate the problem one after the other . . .
test panels, check wiring,
test charge controllers
and check your battery too
one amongst them is the judas

come to think of it . . your single panel on a PWM controller "might" just be insufficient to charge that 200Ah battery to full
in one single 'Sun-day" (not Sunday)

babniyen:
Sorry Not charging adequately. The voltage keeps dropping.
The installation is still temporary, for proof of concept.
Thanks

You are still confusing us.
What do you mean the voltage keeps dropping?

If the voltage is dropping during charge; then it means the charge controller and/or panel isn't supplying the necessary charge
But if the voltage drops after a full day's charge; then check your battery.

please try to be explicit.

babniyen:
Hello house. Please assist with this challenge. I have a 12V dc load drawing 6.3A, a 200ah battery, a pwm charge controller and 290 watt mono panel. Connected it up but i noticed that the battery is not getting charged. Please assist.

Not getting charged at all ?

OR

Not getting charged adequately ?

is it working with glo 4g? I want a device that the primary function is to share internet connection, my phone wireless is not connecting to my Linux OS on my PC but connecting to windows

From the specs, it says it supports band 28 (Glo) too

LTE band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800), 28(700), 38(2600), 40(2300)

@mcTrinity @NiyiOmoIyunade @makavele

Thank you for all the selfless support you are providing here...

Please I am about setting up and commencing my DIY solar project. I have

i. a 3KW, 60A mppt CC
ii. 4nos PV panels whose capacity [wattage] were not stated but made by afromedia. i assume they about 250w each.
iii. 1.4KVA inverter and
iv. 2x200AH deep cycle batteries

Kindly advice what size and type of cable I require between the pv panels and the CC. The distance from pv panel to CC is estimated around 12m max.

Like the initial poster said, there should be a rating of the panels. . but if the stickers have peeled off;
do a benchmark test . . to give you rough estimates . . .for Voc and Isc . . .
in any case, if the panels will be connected in series .. a 4mm to 6mm cable will suffice due to low current.
They can be connected via their MC4 cables if present . . or you can improvise if absent
Battery connect/interconnect cables should be at least 16mm (industry standard)

p.s.: 250 x 4 = 1kwp panels is just sufficient enough to bring your batteries to float just around 1pm or so . .
if your batteries are discharged to 50% during the night . . .
Personally for me, I love to see float around 11am to 11.30 am latest

How true is this anybody?

True

Happy new year. There is a pwm cc most people haven't really taken time to explore , it has good features almost synonymous to mppt :
-it narrows down high panel volt to battery capacity. (You can use 2×2 or 3×3 configurations)
-it has batt equalize settings etc

happi new yr Mr Frank; how are you?
what's the name?

And that thing about voltage headroom . . . has only been discussed as user preference . . .
There is no hard fact or evidence that backs it up 100% . . . it is not etched in stone . . .
You can as well have a VOC of 250V on a 12V battery bank . . .
An MPPT controller will still do the conversion and downsizing very well . . .
There would be losses of course, same for a 45V Voc too . . . There will always be losses in the system.

^^ Spot on . . . but there is(was) never a time when a PWM CC is preferred (or will be preferred) to an MPPT CC (even in small installations)
PWM CCs are only used in small installations due to cash constraint . . . one reason why the installation was done small in the first place.
But anytime anyday, whether for small or large installations, MPPT technology performs better.
The only drawback I have experienced, PWM CCs can tolerate more abuse ! MPPT CCs are the fragile ones of the two.

how are u able to download torrent file with idm

There are sites that convert your torrents to a single downloadable (and most times, resumable) file

e.g. FileStream

I'm in the same boat as you.

Let's wait for someone to answer

Still going strong !!!

He can convenient change the fets. the gate resistor has such a high resistance that failure to the driving circuitry is unlikely. i have change my small inverter twice and i have spares for the next failure . To limit the chances of electric shock from capacitor, put on the inverter after disconnection from mains to use up whatever is stored in the capacitor besides capacitor will give u and unpleasant shock at worst...nothing major

While low voltage capacitors will give you an unpleasant shock; that shock is just enough to mess with
your hearts rhythm for some milli-seconds. . . .
if he already has a weak heart; or is on a pace-maker; you can kiss his ass goodbye . . na grave things !!
Also, capacitors can blow up when still charged and shortcuited; and i pray he is not wearing safety googles when it does.
And finally, I've suffered a major electric shock from a 1.5 HP air conditioner capacitor; it wasn't funny at all . . .
Whilst it wasn't lethal, it was enough to make me call it a day!

dejidotun2000:
Many thanks sir.
Can you recommend a competent technician to handle the repair ?

pm me if u r in lagos

dejidotun2000:
The inverter was not being backfed. It was installed about 3 years ago and no modifications have been made to the wiring/connection since then.

Sh!t happens and electronics can just go kaboom for no good reason.
But you need to give it to a seasoned electrician , , ,
Do not attempt to change the Fets on your own . . because in most causes;
the shorted Fets creates a short inside the gates . . and this damages
the circuitry that drives the gates . . .
Change the all mosfets and connect the inverter;
and you will hear another kaboom ; back to square one.

N.B.: Be careful when you handle circuit boards that contain capacitors; they can store power high enough
to deliver a fatal electric shock; even when they are powered off (especially when the unit was just disconnected; without discharging
the capacitors)

As a shortcut; you could do the usual Youtube "air over ice" method; that's gonna add a lot of humidity to the room.

Then get a standby dehumidifier to remove the humidity from the room. You could even use your A/C as one (the compressor wont kick in).

Saves time and energy, IMO

Most comments on here are jumbled, I'm afraid, with some claiming the truly unlimited pre-existing data regimes, for the new dispensation.

Just to be clear, or AFAIK, the new dispensation - with the new 90 GB monthly data cap, for instance - was advertised to take off on the 1st of this month.

Did it?

If it did, can anyone please state definitely that a new weekly sub made after the first of this month, has been uncapped so far through one week under heavy usage? Such a clarification IMO would clear up a lot of the misrepresentations on this thread.

Obviously, one has to wait until the end of this month to ask the same of monthly users.

As for me with my household, I'll have to wait this new ntel dispensation out a while.
