Electric power P = IV where I = current and V= Voltage.

If you reduce the voltage, there is a corresponding rise in current to maintain same power.

Conversely, if you increase the voltage there is a corresponding drop in current; a principle that allows the use of small diameter wires to transmit voltages over vast distances with less drop in power.

How did this inverter circumvent this basic electric principle?

enolife2:

does this price include solar panel and solar charger?

Pharmtj:
does it require ups ?

ayokellany:
can the installer work in lagos ? I think this is the most economical n efficient.

So I met him today to ask him about this question.... He said I should ask you if u have practically tried it...That you are talking theorically....though they are threshold where ur theories are true....But science has elvovle and it can be maneuvered.
Big English though..
In my own opinion I believe anything is possible... Why? I once forgot to put off my frigde(medium deep freezer) which was connected to my 5000va stabilizer.....and my inverter which is 12v/1.2kva picked both of them...and was working fine for about 30seconds....I had to quickly turn them off.
So I believe anything is possible... And theories can also be changed or maneuvered.(my opinion though)

cute75:

Sorry my message is coming late....Had been busy with work. Well I bought the inverter for 45k...And the maker is base in Port Harcourt.

mctfopt:


In this case, theory is same with practical. About your 1.2kva inverter handling a 5kva stabiliser is simple to explain. The 5kva inverter load may just be 10% of the rated 5kva since it's a medium deep freezer which should be about 400w. The stabilizer is not handling the full capacity of 5kva. Also a 1kva inverter can sometimes handle two times its rated capacity for short duration, say for not more than 60 seconds. It is called the surge or instantaneous power rating of the inverter. So, my friend, what you observed is electrically impossible. And I've got some experience on how some of these things work. Thank you.

cute75:


Bro I asked you if u have practicalized it....u're are still telling me you I've got experience.... I don't have experience in electricity but I know GOOGLE....which I found out that current can drop with an increase in resistance...I=V/R.....I will have to let go of this argument cause I myself have mathematically solve and practicalized some impossible theories in my field of expertise...Biko go google go do research....Thanks!

Pharmtj:
pls respond to my questions, thanks

cute75:

Yes ..I am sure he can..U can contact him...He is from Delta state, but base in Port Harcourt...Blessing-09065876888....please NOTE that this is just an inverter... U will need to buy a battery to connect it...Quantan, Luminous , Ritar ,prag are good batteries.

cute75:

Economical indeed...I'm frugal when it comes to inverter and this inverter brings out the frugality in me.
Well I think its possible to have him in Lagos... He buys most of the raw materials he uses to build the inverter in Lagos...You would have to discuss that with him if need be.

ayokellany:
pls I do not mind can you share his contract

I don’t even have up to your budget to invest on solar yet and I’m already using one as I just hate generators.

My setup:

500w solar inverter-6000 (led tv 32”, laptop, havit speaker with whoofer, energy saving bulbs etc.)

Battery charger- 6000 (10A battery charger)

100ah battery- 25000 (Uk used but battery health is still 100%) there’s more info on batteries if needed like lithium batteries which are lighter and stronger. Also 200ah battery for the type I bought is 45k.

Cable for connection and other little connectors- 5000

Total- N47000

Based on loads I use at a time, it last a minimum of 5 hours, and if I’m on laptop only which is 85w, I’ve used it for more than 8hours and it did not run down.
In my area we have at least 4hours light in a day and if the phcn supply is not faulty, my 100ah gets charged within same period.
For me to have guaranteed light on my solar setup throughout the day, I need a 250-300w solar panel which is like 45-50k at Alaba market and 30A Charge Controller which is like 6-10k depending on source.

Don’t mind me I’m a DIY kind of person and it fascinates to

There are many DC appliances like (dc iron 6000, dc blender 13000, dc fan 10000, dc freezer, dc cooker, dc water pump, dc air conditioning etc) that you can buy now and it can be connected directly to your battery for usage.

I’m available if you have questions.

Pharmtj:
am based in delta and after buying it can it be waybill down to delta ?

can I install it myself ?

TV inputs is 100-240VAC can it power it ,gotv, a rechargeable fan and two energy saving bulbs?

Thanks as I await your response.

bye for now.

I intend to charge it with NEPA (6hrs daily)

Please where did you get the battery?

Meklex:
please I want an inverter too. How can I go about it?

tosinet:


It depends on your need in term of loads you want to carry, your budget etc.

There are solar shops around that can help with your design and installation but if you want DIY, it involves a bit of tweaking and technical knowledge.

Basic components for a solar setup are;
-Inverter
-Solar Panel
-Solar Charge Controller
-Battery

It now depends on the scale of your setup to meet your consumption needs.

Meklex:
I asked o. And they quoted 350k for a 1kva inverter and 200ah battery with three 150w solar panels and other things. I just want to power my regular standing fan, phone, laptop and bulb.

tosinet:
[code][/code]

You can go for a DIY by acquiring the components yourself and get an installer to install for you.

If your load is not more than;
-Normal standing fan not industrial fan
-Laptop
-energy saving bulbs i.e white bulbs

A 500w Solar inverter will carry the load but you can go for a 1000w Solar inverter incase u want to add led tv, decoder or other devices.

500w Solar inverter 6-7k
1000w inverter 12-15k

Solar Charge Controller 30-50A- (3k-7k)

You can get the two items cheaper on aliexpress website.

Then you need solar panel for charging your battery unless you have another source to charge your battery.

For 100ah battery you need 250-300w solar panel while you need 400-450w for 200ah battery. It will determine how fast your battery will charge. Also, having solar panel ensures you have power throughout the day while your battery will power your need in the night.

Depending on your location, for instance if you’re close to alaba in Lagos, components are cheaper.

100ah battery
Used- 20k+/-
New- 35k+/-

200ah battery
Used- 40k +/-
New- 75k +/-

300w solar panel- 40k-70k
250w 35k-60k
200w 28k-50k
150w 20k-30k

So components depend on your location and quantity you are buying.

I did a search on Jiji and connected with the seller. It was a used/refurbished battery and the battery health is at 100% capacity.

This inverter you are quoting 7k, is it modified sinewave inverter? If it is....then its not safe for some electronics, I have seen nairalanders complaining about their electronics getting bad because of modified sinewave inverters. I will advice you do a proper research before recommending modified sinewave inverter.

Deicide:
My own question is that do this things have expiring date? And how long do they last?

tosinet:


Please don’t misquote me...I never said the 7k inverter or modified sine wave inverter is good for all electronics or appliances.

Modified sine wave inverters which are much more cheaper than pure sine wave inverters are perfectly safe for devices that uses “dc current” like laptop, decoders, rechargeable devices etc. It is also safe for led tvs as they have inbuilt diodes and capacitors that convert AC current to DC current.

So if you are powering devices like led tv, decoder, game console, energy saving bulbs, rechargeable fan, laptop etc. Its perfectly safe to use modified sine wave inverters.

Note I also said dc appliances like iron, blender, cooker, freezer, air conditioners, water pump etc. are now available in the market and it’s interesting to know that these devices are connected directly to the battery and not through an inverter.

For those with available resources that want to power “AC appliances” they already own with an inverter, you have to use a type of inverter called pure sine wave inverter. They can safely power AC and DC appliances.
