First an foremost, you will need to calculate the total wattage of all the appliance you want to power.

You only mentioned that of your fans which is 220watts in total; please get all others and add them together; an Inverter that can be at least 2times the required load will be best, so for instance your load is 500watts in total; you’ll need to get an Inverter of about 1000watts, it’s best than getting something just the same as your load requirement, in case of some minor addition long term stability of your inverter.

Now inverters are considered mostly in KVA, find an Inverter that is about the equivalent of 1000w
Which is about 1.2-1.5kva

1500x0.8 =1200w Inverter for instance( the 0.8 is pf)

Or

Converting from watts to kva, you will need to know the pf power factor of the Inverter you wish to get, but before then you can use 0.8


So for instance 1/0.8x 1000watts= 1250kva( you may not get the exact kVa, but this means you can get something higher or a little lower


Once that is considered; then calculate the number of hours you want to run the Inverter.

http://jekitech.com/battery-backup-time-calculator/

To check required backup time

For instance you found that a 1.5kva could power the house, then go to the calculator type in the ah of the battery

200ah for instance

On a 24v system; the calculator is will automatically make it 2 batteries, type in the load, then it will give u an estimate of backup hrs

I really will advice that you contact us; to work you through easily

Wow! Thanks A Billion

The thing get maths o! But really really interesting.
I'll get in touch via Whatsapp.

Meanwhile if you have a known member I can contact in Abuja to help with procurement and installation, I'll be most grateful, if not, I'll seek further guidance via the Whatsapp number you provided.

Again, I'm really grateful Sir.

adrusa:


I think it is because your question is somehow vague. What is your budget? Are you DIY or will get an installer to help you? If you are using an installer, your best bet is to ask the installer to give you a quote. You can then bring the quote here for help.

Thanks for your response Sir.

Can you recommend anyone in Abuja I can engage for procurement and installation pls, preferably someone on the forum if possible.

BENARI:
Good Day House.

I need your advice please. It's possible that my request has been covered here already, but there are now 735 pages to read, and I've tried to skim through, but can't find any, thus my request.

I intend to install an inverter system in my house; for now without solar panel. My house is a 4 bedroom, and I've been told a 3.5kva can power the basic things, namely; lighting, four fans(54watts each), 2 tvs(55inch each), and a small scanfrost freezer.

I'll want to know what I'll require to achieve this, the cost if possible, and the most reliable brands in terms of inverter and batteries. Also whether to use wet or dry cell batteries(talking about durability and efficiency).

I'm sorry for troubling you.

Thanks.

Kindly quote me if responding to my request pls. That will be very helpful.

Yes. The inverter can power them.
The question is, can you and are you willing to get enough battery capacity for this load? Most likely, No.


1) Strive to get an inverter with low self consumption like victron or fangpusun (the transformer less type have lower self consumption when loaded.
Note also the charging current of the inverter, if it's too small, your battery won't be full and in no time it will die.
2) every watt saved is key in extending your battery runtime. Get efficient devices - use led light, fan of 30W or less etc. Inverter type freezer/fridges will enable you to use a lower capacity inverter thus cutting your investment cost and reduction in self consumption.
3) for a newbie, dry cell is better. You won't need to do any maintenance.
4) 95% of installers would promise you that your system is good as setup. The effect of a poorly setup system will show only after 1month to 1yers and by that time payment and warranty would have been completed

What battery capacity is your installer proposing? How many of them?
What's the wattage of all your loads?
How many hours of electricity do you have in a day?
How many hours do you want each load to run?
We can help you analyze what you need if you provide answers to these questions.

Nigerians can never allow the country function normally without creating avenues for extorting.

solar generators/Water heaters (inverters, water heaters) is 5% Import duty, and VAT Free.
Solar cells in panel form or modules is import duty and VAT free
Yet custom charges duties.

I the case of my my small chinese inverter the cost price (Price + Shipping) was even inflated to charge a higher duty & VAT.

I was charged 20% duty with 5% VAT and another charge of the whole amount, that was before VAT was increased to 7.5%.

harizonal123:

Yes it depends on your system but when it comes to lasting hours/ duration parallel beats series batteries configuration. The advantage of series over parallel is that it is used for operating heavy machineries. Yet to find a write up where series connection increases duration

Odiegwu! See the way you're stating it with every confidence... Lolz.

However, a 12V system with two 12V/200Ah batteries connected in parallel has a battery bank of 400Ah... But then, the storage capacity of the battery bank is 4.8KWh (12V x 400Ah)

Now, a 24V system with two 12V/200Ah batteries connected in series has a battery bank of 200Ah... But again, the storage capacity is also 4.8KWh (24V x 200Ah).

THEORETICALLY speaking, if you subject both systems to the same load, the usage time would be same....
>>>Let's assume a 200W load, and neglecting loses and inefficiencies...

For the 12V/400Ah system, current drawn is 17A (200W/12V)
Usage time would be 23hrs (400Ah/17A)...

For the 24V/200Ah system, current drawn is 9A (200W/24V)
Usage time would be 23hrs (200Ah/9A)

....all answers are approximated

PRACTICALLY, the 24V/200Ah series-connected system would last more (in terms of duration) than the 12V/400Ah parallel-connected system due to less conversion loses in the 24V system.

In Summary, using a 12V/200Ah Battery as a case sturdy:
*a 12V/400Ah parallel system has the same storage capacity as a 24V/200Ah series system, but the 24V system is more efficient and would have longer usage time
*a 24V/400Ah series/parallel system has the same storage capacity as a 48V/200Ah series system, but the 48V system is more efficient

The higher the voltage system, the lower the conversion loses, the more panels that can be used, and also the better you can use heavy loads.

Hope you now have your writeup..

Cheers

And when they do that, you have no recourse. No one to complain to. And when you complain, you complicate the issue and you may not get your goods for a long time. Naija jibiti. Yet, na Buhari we all dey blame.

Bros who is to blame? Let the leader of a sovereign country lead by example and watch it have effect of the citizenry.... It's not rocket science.
The only blame to the citizenry (which is significant) would be for electing such leadership

Go for Canadian Solar... And you would never walk alone

Note I just gave a direct answer to a direct question.
I want to assume you already have a designed system, about to be executed. Before you'll go and carry two Canadian panels and put on a PWM CC to charge 8 batteries

How much is 12v 100ah lithium Bms battery?

Yeah, this is the Nissan Leaf full pack I was talking about. You see the crate? That was what was charged for shipping into the country. Weight actually much as my people had to dismantle it to even fit put am inside motor first first. Sienna could not carry it.

Took like 8 people to drop it on the floor. On YouTube it was never explained to be this heavy oo.

Useless panels.. Degrades significantly after one year of production.. Not worth the time and effort...

Stick to tier 1 panels like Canadian solar if money is no object.

Las las, u ll be glad you did.

Solar panels are too cheap to manufacture and sell for you to be rating them this badly. And Felicity is beefing up their name in the industry.

I don't know though maybe it's your set up or you were just so unlucky to buy total trash but solar panels with 25yrs warranty should do better than you stated. Always go to the market with your multimeter when buying panels.

good evening great minds, please I will appreciate if answers can be gotten for the following questions.


1). Those 1.5kva UPS has the same capacity with 1.5kva inverter?

2). Can 1.5kva UPS carry energy saving freezer (200w) ?

3). How can I fix bad solar battery (I picked an old solar battery from someone. He stopped using it about 10 years ago cause he relocated to a place with stable electricity and didn't see the need to use it again. I guess the battery got spoilt in the process of abandonment) ?

4). Can a solar panel of 40w change a solar battery of 100ah successful without using solar charge controller?

Thanks for your anticipated positive response
