Anybody has an idea of the cost of installing thunder arrestor. I think I need one

TechGeek777:
Boss, what can then protect one from direct strike?

Does pv attract lightening?

Even me self tire. And rain will soon start

dollarnaira:
Powmr now 110k?
Omo this is loud.
Naija hmmmm

Bought mine then for 34k AliExpress though.

How was your experience with it? I want to get one too

alosbaba007:
Highest av seen is 1.7k

From 10 - 2 or 3pm on a bright sunny day

My Inverter starts switching as early as 6:40am every single day

This is roughly 60% at noon. That's not too great.

I have read it here several times that the original jinko panels sometimes generate more than the stated capacity.

Penuelseun:
that it is transformer based does not make it less efficient, mine consumes about 11w on standby. 1.2kva 12v

Please what's the name of this. I need something like this for one 120w freezer

Olarewajub:
Good evening, house.

So, for almost a year, I have been off the grid. But recently, I decided to connect back to the grid.

My installer made a connection between the power from the grid and my inverter. So, if they take the light, it automatically switches to the battery power.

Now, my dilemma is that I share a prepaid meter with four other (4) tenants. Would this connection not increase the electricity bill?

PS: My panel is enough to charge my battery, except for this period, I don't get enough sunlight due to their orientation on the roof. I will switch back to off-grid in the coming month.

It will increase it. That thing dey gulp prepaid like mad.
Once in a while I use PHCN to charge my battery too and I notice a significant drop in my remaining unit.
It also depends on your battery capacity sha.

emmy9500:
Hi, please will a 5kva/48v inverter carry 2hp air conditioner, pumping machine, freezer, pressing iron

Yes. But not all at once

Valto:
original fullriver 200ah is between 260k to 300k..how much is 12v 135ah lifepo4 lithium again..?

That's why we say you should be putting these prices here. It will help people like that man choose wisely. Put the minimum price and let them know it can increase based on customisation requirements.

I shouldn't be forced to contact you before I can have an idea of the price of what I want to buy.

Sunnystooth:
My solar panels ain't harvesting enough to charge my battery and power my fridge during the day like they used to before... I know the orientation of the roof I mounted the panels isn't facing the sun directly, but it was better during raining season... Now that it's dry season and the sun is shining well every day, yet I don't get enough power from the panels.... I read about angle of inclination of the sun to the panels this winter solstice period. Yes, my panels are almost backing the sun instead of facing it... I just want to know if that's what is really affecting the harvest or there might be something else... No, the panels are not covered in dust... Just not sure what's the issue... Anyone with such experience or recommendations should help me out please.

Get a ladder, mopping stick, bucket of water and clean it. You will see it bounce back. Mine has dropped performance by almost half this period.

A tenant can actually do something like this. Infact, me personally, I don't like panels on the roof.

Please guys can I order directly from alibaba.com

Good evening engineers in the house. Please is there any difference between these two 4mm cables. The stranded or the one core, which is better

Teaching job? Mbanu.. If it is another job whose experience will become useful after a while, I would have advised you to take.

Teaching job these days is just a waste of time, from poor salary, to useless experience that won't add meaningful value to your life, loads of periods loaded on your head. You will just be wasting your time.

Those years you want to go and waste teaching, look for a skill or business to learn. Make sure you learn from someone that get steady orders so that you can gain much experience in little time.

You will be happy you did.
I still regret all the years I wasted teaching.

dollarnaira:
Ok good.
Test with 219L.
With continuous 6/5hrs daily freezing you should be fine having in mind too that freezing gets better when filled. Bottle waters can be at the bottom of the freezer to help retain freezing if there were spaces.

Most businesses are shutting down due to high cost of energy. Try this method out first to see how it works. Let it be strickly for freezing only.What brand of freezer are we talking about sef?

Thermocool inverter chest freezer

dollarnaira:
The angle at which we see things differ.
Why not test run the set up with one 535w( probably can do up to 400w or more) on the roof of the said shop
or a car port design without shade to see how it goes. Run it for 6hours daily and observe. You should be fine if the freezer is not too big. Litre of freezer matters. 12v is not a bad system as most view it. Infact my whole appliances except microwave and oven run on a 12v system.

By the way, what is the litre of the freezer?

One is 319 litres, and the other 219litres

TechGeek777:
It's likely you will be tempted to upgrade sooner than later, since you are still in the design phase, I will advice you go for 24v 2.5kva Felicity/Crown Ricco Transformer inverter, with 475w Jinko Panel * (4)

Thanks boss

adrusa:
I will suggest you add 2 more panels to ensure that both your freezers and the battery are adequately served during the day. The rest are okay as long as your wife don't become the centre for everyone to come and charge their phones and rechargeable lamps.

Thanks boss.

Good evening house, please I want to set up a frozen food shop for my wife. So I want to set up a 2kw solar system for her. She will be running only 2 inverter freezers 100w each for maybe 9am to 6pm. The set up will be done in the house and we will extend the wire to the shop in front of the house (Like 60yards distance).

Here are the things I planned for, hope I am on the right track?

1. 535w jinko panel (2)

2. 2ka inverter (don't know which to buy yet) please if you have any suggestions.

3. 60a mppt charge controller

4. 12v 160ah Lifepo4 battery

5. 60yards 10mm² cables

6. AC Spd 275v tomzn and Dc Spd 500v tomzn

Only the two freezers are going to be used. Please, am I on track with the above? If not please advise me anywhere you feel is not okay

Uniquewise:
Thermocool outlet.
They are everywhere, just be sure it's a reputable one

OK thanks. I saw one on jumia, I just wanted to be sure

Uniquewise:
Thermocool inverter chest freezer is bae . A mere 100w power. Zero noise. Works so good. Now, I stock up on food items lasting me months. Planning on replacing my fridge/freezer with an inverter type soon too.

Please where did you buy your freezer from? Jumia

sonature1:
Discos buy power from Gencos, and supply it to homes and factories who bypass their meters just to buck the system. Homes who bypass and disable meters are some of our biggest problems.

They are the same people who will wail that we don't have regular power supply in Nigeria. Staying analogue is just a way of augmenting Discos' losses to meter bypasses. The government has been supportive though.

I don't know why we are like this. Simple honesty, you cannot get in Nigeria

I got this diagram from youtube. Hope it will help intending QASA or other DC fan buyers

Oshomo12:
There is one thing you guys are missing here, our electricians don't do DC, most of them are used to AC all their lives. If you give a DC work to any one of them without you supervising, hmmmmm, you are on a long thing. Everything nà 220v for their eyes.

You are actually right, Just bring out the manual first and study it together with him.

All these bitterness because of your own selfish interest

noobody:
Global,
4g.

Cheers

Pls is it mediatek or snapdragon

I was disappointed with the outcome of the presidential election. I thought INEC was ready. I had a renewed hope in Nigeria with the introduction of the BVAS and IREV thing, only for INEC to fall hand.

Good evening guys. Is it still safe to order phone from Aliexpress

LagosG:
Good day, Nairalanders

This topic is directed mostly to those of who live and work in the state capital of Lagos, Ikeja.

I recently moved to an Estate around Adeniyi Jones. I used to live around Yaba. I must confess that power supply here is terrible. In my estate, there are loads of Indians, Chinese and even Europeans. They don't mind running their diesel generators for 72 hours. Me I no get that kind power. My rent is 3 times what I paid in Yaba and we had an average of 15 hours daily. Here sometimes we go a whole 24 hours without power. There are plenty rich folks here too so why? This thing is so painful because I work from home.

Can someone explain this madness

Baba go for solar. I don't know the nature of your work, but if it involves using laptop, a small BeebeeJump S1 can help you with your work

Delphi:
Good. I have always said that it baffles me why people struggle so hard to sell a Northern candidate to the citizenry. It is unfair, inordinate, skewed and a heavy aberration that a Fulani man will become president after the expiration of the 8-year term of another Fulani man. This is the height of insensitivity and aloofness.
This contest is between Tinubu, Obi, Sowore, the SDP man, Abiola etc.
Why should people take others for granted especially having been offered a pot of porridge?
Any Southerner supporting this aberration will not go unpunished by the God of equity. Southerners should get sense for once!!!
May it not happen that a Northerner becomes president after another Northerner-led tenure

Baba you don vex o

I have said it several times here. I don't know why we still have reasonable southerners campaigning for PDP. Once Atiku succeeds and become the president, then the southerners should kiss the presidential position goodbye

maasoap:
Expect that it will be worse because they will be more aggressive in trying to collect the revenue

The same way it's happening here in Oyo state. Once they put on a vest with Auxiliary's logo on it they believed they can do anything they like.
