please what can I do in a situation like this

Try amount CC.

As you are planning to buy hybrid, plan for a good protection systems (earthing in particular).
Repair of those equipment is expensive.

Small lighten strike, office will just open

dbshaywhy:
Thanks for your input... Am not always at always during the day from Monday to Saturday, except Sundays.
With my rough calculations, instantaneous load in the when back can never exceed 360w, while over the night, 80w with century rechargeable fan(mains will be on wen notice its getting low)

My budget 2.2M

This your budget .

You could have stated this first so @jonescosmos no for dey call big names

samistry:
Minor accessories like phones. How much is it for solar kit?

You can get for as low as 150k the higher the back up the more it will cost

saysoo:
8 to 10 hours.

When are you running it day or night

One of this ekuke suppose don ripe today Na Sunday, which one we go use see front

2 ceiling fans!! How many watts each? A TV 2laptops simultaneously.

Hmm just like I said earlier get ready to replace your battery soon of you power all these appliances after sundown.

And you need to add the next battery within the next 3 months or so.

As per the charge current, I wasn't referring to over charge but over current and your battery will most likely swell or explode at some point because when there's no load and there's good sunlight, your charger would be sending over 50amps into the battery.

Just prepare to replace your battery soon it might not last 6months.

Plus the best you will get after sun down is 4hrs power supply if you power on your fans before hitting 50% DOD

What is the function of a charge controller?

I don't think this is true

mikeayus:
I no buy charger for charging from grid ooh, I felt the solar charging will be sufficient already

Okay

Hello guys,

I am a DIY Solar user to be and I have bought the following Items for my setup.

1) 2 550W Jinko Solar Panels (TechLand Solar)
2) 12v 3000w EASun Inverter From a fellow Nairalander
3) 12v 200A Battery Full River From Idyllic Tech.
4) 120A MPPT Charge Controller From Gennex Technologies


Now, I need advise on every other thing I need to get to have my setup up and running (Cables, Change Over, other accessories etc. ).

I would appreciate every tip and learnings from you all. Thanks

You no buy charger for Nepa charging?
You will need breaker or fuse , your load is what would determine the changeover(100A will do), trunks, breaker housing, surge, cable lugs, mounting rails and assembly this is what I can remember

mikeayus:
Uhmm,....well understood...Thank you

@Obnoxious2001 are you an installer or can you recommend any in lagos?

I am that I am Na money dey determine who I can become .

Am in Lagos now.

E go make sense you leave this part for the installer.
Because there are so many shenanigans in this aspect.
This week Na person I help solve this case.
Better still is to hire an someone to follow you.

Guys please I need a quotation (cost)
for a complete solar components that can power a 2hp compressor off grid.

How long do you want it running?

samistry:
I asked a contact for market survey on connection that will power 2 rechargeable fans, a laptop and minor accessories.
Please is this amount correct?

What are the minor accessories?
This quote doesn't look minor. If it those rechargeable fan, laptop the smart solar kit is your best bet.

Jestin:
This country is gone ooo. I didn’t know it was this worse . Bought bag of Dangote cement 12k per bag yesterday

You get mind go even buy 1 bag??

I thought we all agreed to wait till the price came down .

Besides buying land now is the least of Nigerians problem.
As you say make you develop am....

Good day to everyone here, please I need help on my diy , I need help on my solar set up, I have a panel with the following data sheet.
Rated max power 190w
Current at pmax 5.18A
Voltage at pmax 36.7v
Short circuit current 5.6A
Open circuit voltage 44.8v

Cell type ; mono
Maximum system voltage 1000v

and a mpw charge controller with the following data sheet;
Rated voltage: 12/24
Rated current: 30A
Maximum PV voltage: 50V

I have 12/ 75ah battery connected to the charge controller with hope of using the panel to charge, what I observed was that when the sun is at peak the battery indicator on the controller shows full bar and voltage increases up to 17v on the controller. recently I forgot to manually disengage the charging after about 7hr and when I remembered I discovered the battery has swollen, though still working.
please is there anything wrong with my connection? how do I prevent the charge controller from overcharging the battery without me disengaging it manually? did I need to make any adjustment, kindly help pls.

The cc is not regulating properly, because I see no reason why a 30A PWM can't control and monitor the charging

Jirilistic:
Good morning all, my inverter refused to charge yesterday immediately nepa brought light.
There was no light in one of the nepa line so I changed to another phase and there was light

I suddenly heard a kind of alarm sound coming from the inverter and when I went to check, it wasn't charging. Only the indicator on the body of the inverter for when there's nepa light was displaying.

Pls any idea of what could have happened below is the model of the inverter and also the charge controller I'm using


I

If mains is available, does it blink charging?

The fault can be anything.
Just be sure the inverter can still invert.

icjunior:
Be like Gennex dey here o

The guy don reduce the jinko prices😁
10-11k difference from fouani.

Lol.
Make him price no go push am out of market

bassdow:
NO

if you check, you see the columns have headers titled "Application" , "Charging Voltage" , "initial Current"

and that your 80Amps falls under "initial Current". Now that means you shouldn't draw more than 80Amps at a time during cycle use.

if you want to identify the charging current, just look for a word that starts with letter C followed by 2-digits and if you look on the battery body, you would see C10 . Now that's the charge current.

Now, you really don't need those information to successful charge such battery when using a charge Controller or even a reputable charger because they do have charging profiles where you select the battery type.

My oga am loyal sir.
But you seem to be mistaken the C10 on the battery.

Let's also remember we have C20.
And 0.25c written on some batteries

Are you trying to say a 3kva (3000 watts) sachet inverter will power my fridge in the afternoon without any problems
3000 watts sachet inverter vs 1.5kva pure sine wave inverter which one is more better for my 3 bed room apartment

1.5kva transformer based pure sine wave inverter definitely

kristien4:
Pls bosses in the house, Does the inscription on this AGM battery mean it can be charged at 80Amps??

What battery is this

lovediehatelive:
Please does charging phone with charge controller affect the phone?

Does it spoil phone?

Any input or experience.

I'll just use the USB port and put cord.


The image attached is the type of charge controller.
Thanks

No it doesn't

Tover:
Thanks bro ...what about 1.5kva ..hope it can power my fridge without any problems only in the afternoon when I am not at home

If you want to use a sachet inverter, 3kva is your best bet

samistry:
How much should i budget for conncetion that will power a laptop, two rechargeable fans, phones and minor accessories.

A budget of ₦300-350 should get you something tangible.

Your best is to get solar generator. You have the luxury of moving it around easily.
If you want something stationery then regular battery is your guy.

Valto:
exactly the same battery is available for sale. whatsapp me 08020574628

Happy new month.
We have started the month in good faith.
Yesterday's job was tedious, but we are grateful.

So along the line of duty call, I was opportune to meet Alhaji yewa from Sokoto. Man was very courageous considering the complexity of the job, even do I was stressed while executing the task. I was marveled by his courage.

We where faces with relocation of 6 Pcs of 250w solar panels from the main building (storey building), then relocated it to the varanda behind the house.

The job could not be finished yesterday because of some issues (wire that was bought was 10mm but the seller supplied 6mm) I wonder why some people are dubious.

Been a consultant/ 3rd part to the job, when I made my observations, chairman no gree .
I had to calm down and started explain the tricks wire sellers used in selling wire.


He called the supplier and she pretended not to know, but said we can return it and ask for refund .
A whole 200k + for 50yrds of 10mm

Tover:
Good day sir happy Sunday..can I use my bed size fridge with a sachet 1500 watts inverter.it will be only in the afternoon when the sun is out ...or my 8kg washing machine..


Lastly can you help with the things I needed for a 180 litters inverter freezer.,I will love to set an inverter for only the freezer that will be able to work minimum of 17 hours per day

That's inverter is not advisable to be used for a fridge..
However since you want to try it on it, I don't think it will successfully power the fridge.

Nteogwuija:
Bosses in the house, please I have an issue. I connected my 105w freezer to my 1050v inverter, and I got a message saying "short circuit, please check wiring". Please, what could be the cause of this?

Other appliances like my TV, laptop, lights work normal. The message only shows when I plug the freezer, and then the inverter would go off. If it were an overload issue, it would have shown the overload warning message. This is where I'm getting confused.


Thanks for all your contributions in advance.

Probably there is a short circuit in the fridge.
Does the fridge works well on nepa?


If it works well, then know that the inverter can't withstand the starting surge of the fridge

For this panel matter, make we talk true it seem like Alaba come dey cost for original capacity.

Men I installed some fairly used today, and it was just too clean to be fairly used.

If that panel reach Alaba, Na new one then go sell am as after them don put the cartoon, knack am Canadian solar

hollaryincar:
Good day house,

I've been following this thread for a while, Please I need an affordable and trusted solar installer somewhere around Ayobo, Alimosho, Lagos.

My family want to instal a solar inverter system, We already purchased the major components (Solar panels, battery and inverter already)

.

Am not around any of those places.
But if you need to get the job done you can hit me up, that is if you have not gotten anybody yet

DaniellaDokubo:
Good morning fellow enthusiasts,

I'm curious if anyone has experience with back feeding excess PV harvest into their grid supply. My inverter has this feature, which allows me to do so. I'm wondering if it's possible for my prepaid meter to roll backwards, enabling me to buy back some units from the grid.

I appreciate your prompt response and wish you all a fantastic week ahead.

Best regards,

Our prepaid meter doesn't support it.

Besides which sub station to you want to send it to?

Your best bet is to sell the electricity to your neighbours.
It will require 2 Meters, the consumer and your monitoring system.

bassdow:
experienced person no go get issue with that. Also, even non-experienced person shouldn't have much issues with that.


That's hardly an issue. Worse case scenerio, you place something on top to cover it BUT I have never done such becase the coating is more than enough

This are the challenges I have witnessed
