After posting my Steem Solar & Electricals report for August 2024 a few days ago, it was a little bit weird as I couldn't make much profit that month, and I didn't do any solar installation. However, I remained optimistic about September's prospects.
I got some interesting encouragement from friends.
The happy time
Three days ago, I received a call from an unknown number. The caller asked if I was at the shop, and I confirmed. 15 minutes later, he arrived and began inquiring about solar installation for his video-game shop.
He also expressed frustration about the substantial amount he'd spent on petrol recently and criticized the government's negligence regarding the struggles of the common people of the country.
To cut the long story short, we reached an agreement, and he made the payment. The installation was completed on Thursday 19th September, 2024! 😊
The installation
System profile:
- Inverter - 2.5KVA
- Voltage - 24V
- Panel - 400W (6 pieces)
- Charge controller- 60A (MPPT)
- Battery - 220Ah Tubular (4 pieces)
- Wire - 10mm
- Location: Game Haven, Ekamba Nsukara-Nwaniba
It was a big installation that took almost my entire day, hence, the reason I couldn't post the interview showcase on Thursday this week due to how busy I was.
I still have them plenty, come for it
I first sorted out the components and my tools.
About shipping the panels to the site
And I made arrangements for a tricycle to convey it to the site. I had to plead with the driver to help take these photographs 😀
Since this was a heavy job that has to do with lifting of the panels, I needed a helper, so I invited one more person to assist in atleast lifting the panels.
The weather was good and harsh 😀 because of the sun. But this is what I love to do, so I didn't mind.
Work is about to start
Stage 1: Panel mounting
I started my installation by mounting the panels. These are heavy panels that required two people to lift if to the roof.
Before mounting panels
A very important part I'll like to highlight here is that the panel connections were series-parallel configuration since it is a 24 Volt system.
That is - 3 solar panels were connected in series (1200W, 60V), while 2 sets of series-connected panels were connected in parallel.
My assistant tightening the first panel based on my directives
Connecting the panels
I did the entire connections by myself while my assistance was just helping me to hold the panels.
As the CEO of Steem solar & electricals, I ensured a proper installation for a better functionality
It is important to give attention to this panel configuration.
Panels installation is successfully done!
After spending 4 hours on the roof, the solar panel installation was successful.
Stage 2: Connecting the batteries
Before installing the battery
Installation of batteries
Remember, this sytem is a 24V system and connecting 4 tubular batteries(220A) for a 24V inverter requires a specific configuration to ensure safe and efficient operation as it should.
Each of the battery were 220Ah by 12V battery.
To achieve 24V, I connected the batteries in series-parallel configuration as I explained below.
I'll choose to label my batteries as follows for explanation purpose :
- Battery 1
- Battery 2
- Battery 3
- Battery 4
While,
+ for positive terminal
- for negative terminal
Battery configuration diagram
Let's understand the diagram's connections which are in two form
Series Connection (2 sets of 2 batteries)
Connect Battery 1 (+ terminal) to Battery 2 (- terminal). [First series]
Connect Battery 3 (+ terminal ) to Battery 4 (- terminal) [Second series]
Parallel Connection (2 series sets):
Connect first series (+ terminal) to second series (+ terminal)
Connect first series (- terminal) to second series (- terminal)
Last Connection:
- Connect the combined (+ terminal) to the inverter's 24V (+ terminal) input
- Connect the combined (- terminal ) to the inverter's 24V (- terminal) input
The whole of these explanations were what I did, so I am taking time to explain how this is connected.
After the entire battery connections, I connected the 24V battery bank to the 2.5KVA, 24V inverter system and then the MPPT charge controller to 24V battery bank.
Note that it is the battery that is connected first before connecting the panel array to the MPPT charge controller.
Check out the result below..
And the work is done!
I spent almost 7 hours on this installation, but I am grateful, it was a success and my client was happy with my services.
It was a stressful day, but it was a money making day 😀
Should you need such services or a solar installer, please kindly contact me especially if you are from Nigeria.
Also, I can carry out solar installation in any part of Africa and outside Africa.

Thank you so much, I get better everyday with my installation techniques.
Ofcourse he was very happy despite the high cost of buying it.
Now, with this, he can operate his game house smoothly.

That is awesome job that you have done, you are one man business and that makes it a bit difficult because the whole process is done by you, being a seller, finding client via advertisement. Also the whole work that needs to be done on roof laying the panels and connecting correctly. Everything depends on these little nuances. It always will be good time with good business and then some quite time, wishing all the best for you!

Thank you so much..., I think doing all those things are training. In the future when I have grown in the business..., I will have people who will assist me in most of those things. I am grateful for your nice feedback.
