Nice one, I commend your effort being your first DIY installation, You saved some cost but it will only be for a short while. As time goes on when you broaden your knowledge on Solar inverter electricity, you will be able to correct certain things..... I will highlight a little for you to research on
Firstly, your Solar inverter is mostly likely not a pure sine inverter and that's why it is cheap, it might even be a square wave form inverter which could damage your electronics in the long run.
A single Mono panel (180watts) won't be able to able to charge your GBM 180Ah battery sufficiently on a daily basis, this will affect the life of your battery
You could have waited a little while to buy a quality battery that hasn't stayed more than 6months, RITAR, GENUS, ADDO, QUANTA. but also know that battery purchase is also luck, it's 50/50 no matter the place or warranty given
For your GBM battery to last longer, you need to charge with a smart charger
Lastly, during raining season, you won't have enough sun, you still need a back up generator
I wish you all the best

I just did a solar setup yesterday and I have been evaluating. It's nice to see the inverter start charging from 7am until 6pm. If you want a contact I can share my solar guy's contact for you to get a quote

PeaceJoyLove:
Nice one bro.

A single usage must not be lower than 70% of your battery if you want it to last. Well, it depends on your battery as some can still take 60% to 65%. If you keep using your battery below the level specified on your battery, it will kill it fast.

So, every night you use it, make sure it doesnt go below the recommended level which is always btw 60% - 70% of the battery.

Goodluck bro!

A lot more people are embracing alternative source of power and as it is worth every penny. I always recommend Lithium battery for portability and longetivity, i assembled LiFePo4 battery for inverter and Laptop use as external battery. Presently we have 3 size capacities 300wh, 480wh and 1260wh and they have been making the difference for our clients. We are reachable on 080653..16307 www.cooldipo.com

Well, since you are the one that did the installation and not the electrical guy, you must make sure you follow the basic rule of electronics. And that is, to make sure ALL THE CONNECTIONS ARE VERY TIGHT.
Nothing destroys electronics more than a lose wire that is just lose enough to allow an electric arc/spark to keep jumping across wires. That spark is called Plasma. It is neither a solid, liquid or gas. But it is as hot at 10,000 C. A tiny thing will burn and melt wires and create bigger sparks and more heat till the whole connection will burn.
I hope there's a point for Nepa to charge the inverter and batteries as well. Because you'd be surprised that you won't always get 8 hrs of Sun, Mon - Fri, January - December in this Nigeria.

Tons of info, assistance, tips and by the time you're ready to expand the setup you'd be better prepped. Nice one.

Well, great people of FTA, I think I should start this on behalf of George_D because of the request made by others who have expressed interest in alternate electricity, especially solar energy. Our FTA independence is not complete if we are to suffer frequent power outages and been dependant on the nation’s electricity grid system always. I have read in this house many times, from members “PHCN don go off, so I will track later when they come back”. No one can run away from power outages in the main electricity grid – not even the west, it happens. Hence, we all should have alternate electricity and using renewable energy is, to me, the best. This means one can enjoy their FTA fully by being totally free and not “dom” (dominated).

Look at some advantages
• Lower or no electricity bills
• Compared to generator users, there is no fuel cost and stress of getting it and no fumes.
• People living in the remote locations where power is unavailable or too expensive to hook-up too can have electricity.
Just to mention but a few.

Without going into detail, one can enjoy electricity by means of using solar energy (energy from the sun), wind mill (using energy from the wind). Don’t forget, where there is frequent electricity supply from the utility company, you can store some energy for back up.

You will need the following to complete a solar project or back up.

1. Solar panels
2. Power Inverter
3. Charge controller
4. Batteries to store energy
5. wires and cables
6. Monitors/meters

The solar panel consists of cells called photo voltaic cells and these, covert the energy received from the sun to electricity in simple terms (this electricity is a direct current
d.c). The panels can last up to 20 years plus. The panels can be fixed, adjustable or of the tracking type. You can decide to go for a complete panel from manufacturers (already made) or build panels by yourself using solar cells- the latter is for the hobbyist. The panels are rated in watts eg 80w solar panel supplying 12v continuous at a given time

The inverter
Power Inverters are available in 3 basic designs, two of which I remember very well now – the one that out sinusoidal waves and those that are modified sign wave type (meaning not pure sine waves and do have limits when it comes to its application) . The power inverter converts your storage battery power into the 240 volts AC that runs your appliances. It is the heart of your solar energy system. Unless you only run 12 volt DC appliances you will need a power inverter to supply your AC. This is just the basics.

The Charge Controller
A Charge Controller is necessary to protect the batteries from over charging and supply them with the proper amount of energy to promote long battery life.

Batteries
Without Storage Batteries to store energy you would only have power when the sun was shining. There is a lot more to batteries than just the ordinary car battery. Yo may need to change batteries over the years.

Wires and Cables
Without the right size of cables, you are likely to experience inefficient transfer of power (greater losses) and overheating.

Meters
This is required to monitor the performance of your solar system.

Firstly, it is very necessary to know what gadgets you will be using (eg.tv, sat. receiver) and how long you will use how long you would have them on the solar power and how much energy your battery can store and which solar panel (rating in power) will supply the required energy.

A lot goes into calculating the cost of setting up a solar system. First one has to consider the period of usable sunlight available at their location to do this calculation. For us here close to the equator, we get about 7 to 8 hours or more of sunlight during dry season, just a rough estimate.

How do I know I need 100w or 80w or 300 watts solar panel for my project?

The power consumption of appliances is given in Watts. To calculate the energy you will use over time, just multiply the power consumption by the hours of use.

Eg. If I have 90W tv set which I want to use for 6hrs, 25W satellite receiver for the same period, and a 50W fan for 3 hours. What will be the energy required from the solar panels for the period?

1. the energy for each appliance is Watts x time (hours) = Wh

So, the watt hours for the tv = 90 x 6 = 540 Wh (watt hours)

Watt hours for sat. receiver = 25 x 6 = 150 Wh

Watt hours for fan will be = 50 x 3 = 150 Wh

2. sum the watt hours for the individual appliances ie. 540 + 150 + 150 = 840 Wh (watt hours)

This means that the solar panel will need to supply 840 watt hours of energy to the battery each day to cover the total power required by these appliances.

3. since there are bound to be losses in the system However, to account for natural losses, we multiply the result by 1.2 (this factor allows for natural system losses, assuming 85% efficiency). Therefore, we will assume the panels will actually need to be able to supply a total of
840 x 1.2 = 1008Wh

4. so, to supply 1008Wh of energy the panel we assume to receive 7 hours of sunlight will be rated at 1008 Wh / 7 h = 144W
So, I will need 144W solar panel to supply energy to my appliances above at the given time.

Regarding point 3, it also means, if I have a solar panel rated at 100W receiving sunlight for 7 hours a day, the total energy supplied considering 85% efficiency will be 100x7x0.85= 595Wh and not 700Wh

5. Your battery should be able to store 1008Wh of energy. Since batteries capacities are rated in Ah (Ampere Hours) you need to multiply Ah by the Volt rating to know the Watt Hour. Power(W) = Voltage (V) x Current (I) ; Watt hour = VxIxHour

Therefore Ah (which is I x h) = Wh / V = 1008 / 12 (the number 12 represents a 12v battery)
= 84 Ah

So it means you will need not less than a 84Ah, 12V battery (deep-cycle batteries, not ordinary car batteries) to do the job.

NB. Another way of calculating battery capacity is explained in this example. Should my battery be rated at 84Ah, 12V the watt hour (energy) will be 84Ah x 12 V = 1008Ah

It implies that the battery can supply a 150watt appliance for 1008/70 = 14hours

Pls don’t just play around with batteries they are dangerous.

lasthero:
Total cost:

Battery : 85k
Solar panel : 30k
Inverter : 35k

Total: 150,000 naira.

I bought wires 2k

Making 152,000.

My observations so far
It takes 5 to 8 hours of sunshine to charge the battery from 0 to 100% depending on the sunlight intensity.

And guess what guys. When all the house load are on it, it lasted me up to 8 hours to use up a single charge. But when I put of the fridge, the 45watt fan and when my laptop isn't in use, it takes more than 12 hours and that's exactly what I needed.

Burning 8 to 12 hours on petrol daily will send me back to my village.


Thanks for coming to my Ted talk

How is Odenigwe now ? As I was not shot dead in that area eh! Saw me challenging one deadly Tall Barry and sending strong message through his bad girl girl friend known as Peace when she wanted to obtain an innocent year one girl . At Margarate Catraight DUST BIN END one night, I went through group of executioners rushing out of odenigwe . Few hot leads , flying past me without change steps. An only son was killed in a hit one morning and everyone thought I was the one until I showed up from a class. God really covered me! Powertronites , I dey hail o. UNN , my Alma mater

2 died before lekki toll gate incident.
(Kayode salami, folorunsho mercy).

3 deceased have no surnames or family names( tola,jide, and wisdom).

Nathaniel Solomon that was declared dead in 2020 granted interview with punch 2 months ago

The end sars panel report is a joke. By the time FG and Lag state finish dissecting the report it will be shredded and thrown into dustbin

Patrioticman007:
Law of Karma is taking effect on Igbo's younger generation, for their parents destroyed millions of families by selling hard drugs in the name of codeine, ryphonol, cocaine, crack cocaine & other fake drugs by selling fake malaria drugs, typhoid etc to dying patients. Mkpurumiri will surely end their children also.

Christistruth00:


The report is Fake and unsigned

The report is fake

Check page 304 it listed only Abuta Solomon as a Fatality from at Lekki and his brother Nathaniel was awarded N25 Million Compensation

There was no massacre at Lekki

benuejosh:
Ruined and hijacked are different things abi?

Did the army orchestrate the destruction of properties in Lagos?

IPOBs did. Nnamdi Kanu hijacked the protest in the South West and caused destruction of properties simply because of Jealousy that he has against the west.

This proves once again that people from that side of the country a.k.a. developers can sell their parents for money. Imagine selling an exalted position to an enemy whose foot soldiers have killed thousands of people including your own brethren. Even Pantami's fellow heartless killers in ABTU rejected him, but our developer brethren developed him. What a people!
