I can't use the bars to tell what's happening.
The voltage will make it easier.

How did u know the connection of the solar panels.

Thanks
Panel Connections: I connected it myself and I watched it on YouTube

Negative on panel 1 connected to positive on panel 2

While we connect wire from charge controller accordingly i.e negative from charge controller to negative on panel 2, positive from charge controller to positive on panel 1

Also, voltage seen on charge controller varies from 10 - 11v around 7am till something 9. From 9am, it's always above 12.4 that it shows

Thank you

Please go back and reconfigure it.

While doing this, please try to measure the voltage of the panels individually.

Experts in the house.

Good day everyone, I need a solar power solution (at least the inverter and battery and charge controller first) for my laptop and smartphone only. The laptop is 90 W.

My budget is ~100k (to exclude the solar panel). I will get that one later.

I'd like to have a very small Inverter (150W or so) coz I don't intend to run anything else on it. Just the laptop only, and phone.

And I'd like to have at least 75 Ah battery capacity (or higher) for a start.

I want the power plant to be able to keep my laptop running for at least 9 hrs in the day (I'd charge it then take it off the inverter, then reconnect it when the laptop battery runs low, etc). The laptop itself stays on for at least 2hrs until it runs low.

I'd like the SCC to be around 30 A to make provision for bigger solar array (for faster charging of the solar battery) in future.

I need assistance on how possible it is to put together such a solar power system.

----------

I did some findings and I saw some products on Jumia.

I was particular about their battery capacities (some people were clever to stamp outrageous mAh and Wh ratings on their products).

But I observed some had 25 Ah battery. Others had 40 Ah, while one had 75 Ah.

I feel 25 Ah would be too small for my purpose.

I'm not also comfortable with the 40 Ah option. Do you think a 40 Ah with 60 W panel and 500 W inverter would be okay for my needs (as described earlier)?

The 75 Ah package caught my attention. But I didn't like the 20 A charge controller that came with it (I felt it would not allow the solar array to be scalable). I also didn't see the need for their 3 kW inverter. I spoke with their contact on phone, but he was sounding very impatient and non-responsive.

But still I'm interested in that 75 Ah capacity. What do you think? Can I go ahead to buy it? They said it's ~140k along with their 160 W panel (108k without the panel).

Please I need someone to guide me. Someone I can personally reach out to and talk with.

I'm based in Badagry.

I've changed to parallel and positive changes noticed

Now, one more request

I watched the battery reach full today but I used it to some extent till it return to 3 battery bar and continue charging

3 bar remained but I switched off the inverter to enable battery continue to charge from around 3pm till evening but to my surprise, when the battery stopped charging it only shows 2bar whereas the continuation of charging showed 3 bar

Does that mean something discharge the battery?

I noticed reduction in voltage too because when the battery still under charge, it shows 12.6 as battery voltage and 12.7 as panel voltage going into the battery but when the panel stopped charging, the voltage showed 12.4v

I will need your input as regard this if it's normal or something is wrong somewhere

Thanks

This is quite normal.
For batteries to charge, u need a voltage higher than the batteries voltage, so I can attribute it to the extra voltage from solar panel.

Please try to charge the batteries full before using them after the previous incident.

That aside, weather has been bad for sometime now, for the first time my 12v system off on me....

Good job you are doing keep it up

Good afternoon Sir,
Please I am in a srict budget. I need a system that will charge my laptop 90w (preferably, in the daytime), then tv(dell monitor), at least 5 lighting points (will change all bulbs to 5w) and decoder.
All items for at least 3-5hours in the evening.
Fan can wait.
My budget is very low.like how much will that take

2 X 180 watts panel = 90k for 2

100ah battery = 72k

1kv inverter = sachet cheaper but you can get reasonable ones like famicare or yohako (cost around 70k)

30a Charge controller = 11k

270k will do you

Depending on your location, your budget should be around 470k upward.

This will get you something ideal.
A 200A battery 12v
Inverter and controller
Wire and accessories for the installation.

MPS 2 Lite can get you that connected to solar

Ournolly:
As much as I applaud your idea and the clear explanation, I will however let anyone interested to understand clearly that 40ah deep cycle led acid battery won't go far at all.

With 50% dod one can only get only 20ah which makes extremely poor for even 1 room apartment.

I know you were trying to drastically reduce the cost but the above listed is far below the minimum not even mentioning that solar set up cost far more.


I am currently in conclusive part of powering my 2 modern bedroom flat with 2 heavy 200ah monbat battery and the necessary addons. This alone is costing me over 600k.

If the load is optimized 40ah battery would go far.
I help people setup solar systems which are cheap and they work flawlessely.

ok sir, sorry i cannot be more helpful at this time. kind regards!

Hello House,

How can I calculate the ratings of inverter, battery and panel needed for 150w load. Intend to use it for 6 hours per day. 2 in the morning , 4 hours at night.

Thanks

Mordecai:
Solar power is considered out of reach of the average middle class income earner.

But is it?

Let's go into it, step by step.

I hope, by the information I'll be detailing below to encourage most low-income earners to adopt solar power for their needs. It is not as expensive as the resellers would have it be.

NB: I am not a professional. Most of the views I'll express will likely be as a result of my own experience.

Hi please how can I reach you? Just need some guidance about solar,
tried searching if you’ve posted a number before but can’t find it anywhere

Hi Guys,

So after seeing shege by buying over 40k fuel every month for the past 5 months. I've humbled myself.

I need a solar inverter system to power my laptop. Just my laptop. Unfortunately, its a 170watt rated laptop so its quite the power guzzler. So key things I need to point out:

1- it's just for my laptop, not the whole house. So like a DC connection to a power outlet/extension is what I'm looking at as a start
2- I want to be able to charge it with Gen/Nepa/Solar
3-It should be expandable. So I can add additional battery and eventually modify it to power the house in the long run.

Location:lagos
Budget: #200 - 300k.
Time line : 30 days.

Your advice/recommendations would be appreciated.

Let me arrange an estimate with a budget of 250k

100A battery @ 75k
250W solar panel @60k
1000w PSW satchet inverter @ 40k
40a pwm Controller @23k
Wire @ 18k
10A smart charger @ 20k
Workmanship @ 17k

This will do.

You should have back up of 2hr50mins with the load you mentioned.

I am appreciative of your response. One thing though, i'd like to future proff myself and i'm thinking, would it not be safer for me to get like a 1.5KVA rated inverter. With maybe the +50k left, i can have wiggle room for that before i start thinking of expanding battery capacity. or what do you think. Go for 2 batteries now or go for a higher output inverter?
