Few corrections
1) it's rare to get 7200WHr from a 1200W solar psnel in a day even with premium brands of panel and cc. Use 2-4 times of capacity.
2) 70% load on an inverter in inverter mode though adequate is not sustainable in the long run except for premium brands. The inverter may not last long
3) starting point for solar calculation is not load in W but in Whr. You have to consider each load and how long it is on.

Nice contribution boss.
1 It's possible to get 7200w from 1200w in Nigeria if your panel are properly positioned and face where it should face. Mind you, with the calculation i showed, i didn't mentioned that he must use 1200w solar panels by force. He can go higher if he could afford the cost while introducing the calculation formula to get accurate hours it could get charged.




2 You are preety right here. I can't even advice anyone to go for such low wattage of inverter but i had to show normal standard calculation for better understanding. Another thing is that inverters itself also consume battery but i don't want to go deep and that was why skipped energy loss for all.


3 I won't argue with you with this, but I want you to realize these:


1 The watt of a single solar panel, measured in watts


2 The energy supplied by solar panel over a period of time installed in a specific place measured in kilowatt-hours kWh.

Malevonent:
does the qasa have remote control?, am not too keen on it being energy saving, anything below 60w is ok for me.
its the remote control fxn that is my priority, since the fan will be hung high up in the kitchen ceiling

@gtech2sure, good attempt at the calculation, however several errors exist.

1. even though batt has 2400w, you can only safely take out 50 to 70% of it, best to use 505
2. your solar calculation is off, but since the OP says, no solar, lemme keep quiet
3. its best to size your inverter to be 2x or 3x the anticipated load, as inverter efficiency reduces if loaded near capacity. i would recommend, a 2.4kva minimum inverter

Thank you for your contribution, i am also open to gain new ideas.


1 Please check what i posted. I said i don't want to go into energy loss calculation and that's why I skipped this. Discharge energy loss in lithium ion battery is 25-30% while discharge energy loss in lead acid battery is 50% so i'm still on point.


2 You said my solar calculation was wrong please kindly help me out by showing me the calculation required for solar power to charge 7200w battery.


3 You are right due to the way we do our things in Nigeria but in normal standard Inverter should be greater 25% than the total Load

stokfrick:
Experts ln the house
I want to set up a solar power system, please
I need to get the best brand(s) of the following
The total load iS 700watt
It will run for 8 hours daily

1. Lithium ion battery 200maH
2. Pure sine wave inverter(pls what power rating would fit?)
3. Mppt Charge controller
4. Solar pannel, 300w

Let me quickly brief you on this. I am not an installer though but a fresh graduate who understand basic Electronics, Electrical and Computer Engineering all together. I had solved solar system problems for few installers who got lost for proper choice of components used and calculations. This calculations pretty work well


I am going to show you simple calculation to know like how many solar panel you need, watt of inverter to use, battery, charge controller and time to get a full charge using calculation.


Mind you, the calculation aren't hard. We only need addition, subtraction, multiplication and division.

Now let's begin
Before i proceed, there are some calculations i will not include in order not to make everything complicate, the calculations are based on energy loss in solar inverter system. With the one i will drop here, you can become an installer overnight with the help of youtube for practical aspect.

This system will be designed in 24v


LOAD: 700 watt

INVETER:
Inverter should be greater 25% than the total Load


Therefore load = 700 watt


700 x (25/100) = 175
700 + 175 = 875 Watt
This is the rating of needed inverter. But go for 24V, 1000 watt inverter or higher


BATTERY:
To know the total battery that could power load of 700 watt for 8 hours, just mutiply total load with time.
ie 700w x 8 = 5600w
This shows you need battery that could generate 5600 watt of power for 8 hours.


Use this formula to convert AH of the battery to watts.


W = V x AH. where w= watts, v= battery voltage and AH = battery amps.


Therefore: 12v x 200ah = 2400watt


Mind you, the system design is 24v
Due to this, you are going to use six 12v, 200ah battery where the three steps battery will be connected in series while loop them together in parallel to give you 24v, 7200 watt.


I know you might be wondering that the watt of battery we got here is more than what we need, just don't worry it's an added advantage. Our 7200watt battery here could power load of 700w for 10 hours.


It's done in this way:
battery watt/load: 7200/700 = 10.2 hours


SOLAR PANEL
To get solar power rating to use and time to get your battery charged depends on choice but i recommend 6 hours charging time because of cost.


It goes this way
Time to charge: battery watt/time (hour)
= 7200/6 = 1200watt
Your battery will get full in 6 hours with solar panel of 1200wat.


Note: You must not put ON any load on the system for you to get full charged within the period of 6 hours. But if you can't abide with this, you have to budget extra 700 watts solar panel to your cost


VOLTAGE CONTROLLER OR REGULATOR:
Power rating of solar used to determines the power of regulator to use.


Note: That Regulator rating are usually in Amps which you would need to convert to watt.


The regulator can be gotten using this formula
A = Solar rating (watt) / Battery voltage
= 1200 watts / 24
= 50 Amp


Therefore, you need 50A, 24V charge controller.


In summary this is all you need
24,V 1000watt inverter
Six 12V, 200AH battery
1200watt solar panel
24V, 50amp charge controller.


Goodluck..

Over the next 6 months, I want to do an experiment to work on something - a new challenge. I reverse-engineered the Skyscraper strategy by Brian Dean (Brian Dean is one of the top SEO brains in the world). I'm not going to reveal my strategy as yet. But you can read about Brian Dean's skyscraper strategy online. But I'll show you what I do, so you can follow along.

Here's what I am working with:

- A 10 months old Fiverr account with only 1 real review. The other reviews are shit reviews (bought). I didn't get any ROI though. Waste of money.
- I have created the first gig. The reviews are obsolete so in short this Fiverr account really has nothing going for it.
- It's a Nigerian account in the over-flooded writing niche. So I literally put the odds against me.

I am not going to show the account name. Only new order screenshots as they come in. But I'll tell you what I have been up to everyday. Stay tuned.

PS: I have a FREE PDF to teach you the a,b,c of making up to $1k monthly from Fiverr (if you can put in the work). Just send me a message if you want it.

PSS: Of course, 7 figures is in Nigerian currency

Please i need the pdf also.. gtech2sure@gmail.com
Thanks

Fiverr really wants to deal with Nigerians. Be careful if you have multiple accounts.

Seriously, the same way they moved my shining gigs from first page to last page. Since November, 2019 no order anymore.

Use the money to aquire a skill in social media marketing. Once you become a Facebook ads manager, You can be raking atleast $300 - $1000 every month if you are offering the service on fiverr.

I'm also looking forward to add this skill to my hustle in 2020 but yet to see any freelancer who would mentor me face to face.

1. Create a Facebook business page

A Facebook business page helps to make post of your business and it's offers on Facebook and also promote the posts and get it engage by your audience. I.e your audience can like, comment and share your posts and the more engagements you get the more audience you'll reach.

So click on create page and click on business page

2. Define your marketing objectives

Your marketing objectives is the goal of your Ads. In our case the goal of our Ads is to create conversions not awareness nor considerations.

So under conversion, you have to choose increase engagements in your app. This is because you are a beginner seller and you only need people to click on your Telegram like which will take then to your channel on telegram App.

3. Set your preferred target audiences

This is where you set the target audience that you want to reach. You can notice fron the 2nd and 3rd screenshots that i specified the regions I can easily deliver my products to intented buyers by my self because i'm a beginner seller. So i have to stipulate the cities where my delivery mobility can reach.

You can also see that i target single gender i.e female, and observe how i set their interest and age limit.

Note: Always set age limit btw the age of 28 to 40 because you wouldn't want unserious buys to order your products and from my experience people btw this age limit have proven to be potential buyers.

Boss, in this aspect of Facebook ads, you asked us to choose "increase engagements in your app" and it will direct buyers to telegram app.


But what if I use a sales page website like yours, what would i choose under conversion of the Facebook ads?

Do you remember that DSTV came to Nigeria during the time of Sani Abacha to offer us free to air but he chased DSTV with huge tax. Tell me have we being enjoying classic free to air now?

Let me tell you the bitter truth, Obasanjo is still our best president since this time of democracy.
