he come up with this inverter and battery, I check on the inverter name it's microtek inverter, though the price online is 10,000 cheaper but I am worried about it's late response, I just want to know if the inverter and the battery are good

Yes they are okay.
One advantage of the inverter is, it can easily be fixed in case it has fault.
Carry go.

Thanks for your time.
I just don't want to overwhelm or underutilize the system.

Your welcome boss

Lagosbynature:
Thank you for this response, since I’m on a budget, I’m considering buying only a 300w or 350w panel, PHCN supply will supplement it.

I do not need the Panels to power my load while charging my battery anymore. I only need it to keep my battery charged during the day while I put my load on the inverter which will be connected to same battery.

I guess that makes sense?

Did i also mention my inverter is a inverter/ups, so it has inbuilt charger for electricity charging of any connected battery, it plugs to a wall socket.

Yeah it does.
300w is sufficient enough to charge within 5hrs of sunlight

b0rn2fuck:
thanks a lot, I demanded the product in picture or name because I wouldn't want to do something that won't even last 3 months.

Your welcome boss.

@obnoxious2001
I have a 24v 2.5kva hybrid inverter with 2 x 220ah tubular batteries, 60a mppt cc and 6 x 230w Canadian solar panels.
My installer told me I shouldn't allow d battery voltage displayed on the inverter to drop beyond 24.7v.
The inverter also displays usage percentage.
My question is, what are the parameters I should be looking at during usage in order to prolong my inverter system's lifespan?

Thanks in advance

Your battery voltage mostly (I don't want to start mentioning Technical terms)

There is what we call depth of discharge (DoD), this is probably the reason why your installer asked you to stay within range of 24.7v
then charge controller charge rate.

From experience, most inverter has a cut-off of 10.5 very few products like luminous (am not sure) has 11v (it translates to 21v and 22v respectively on a 24v system).

But 24.7 is not yet up to 50%. I attached an image of various system sizes

Lagosbynature:
This is my current setup

1kva 12v Mercury Direct Inverter/UPS

12v 100ah Battery

I charge it from wall socket via phcn/gen.

I want to switch to Solar and I want the solar to power my load during the day while or after charging my battery.

Heres my load

1. 170w laptop
2. 60w tripod light
3. 24watt fan
4. 100 watt for miscellaneous (phone charging etc.)

Note all of this will not be on power at the same time.
Max, 1,2 and 3 load will be on power, making 254 watt max load simultaneously.

Q1. Can a 300-350watt mono solar panel power this during the day while charging my battery?

Q2. If the solar panel cannot power 250watt load, will the load fall to my inverter and battery whilst they continue recharging from solar?

Note: The mercury direct inverter/ups has inbuilt charger that charges my battery when plugged into a wall socket for phcn/generator

If you want to go solar,
You will be needing 4pcs of 300w to power your load continousky and charge your battery as well. A single 300w will charge a 100ah battery comfortably.

The higher the panel watts, the faster the charge and the higher it's harvest

Advantage is you can run all this load as long as there is sunshine (I used 8hrs as the run time)


2. Yes.
The battery will compensate for the downtime the solar panels will face (it's very minimal and it depends on weather)

fatherbeeman:
Pls how good is starplus battery for 145k and Afriipower for 173k? Any better option?

I was going to recommend afripower.
For the inverter.

For the battery, starplus isnt a bad option
Just that you have to make provision for a Seperate external charger to charge the batteries (tubular needs deep charging)
You can go for genus of you are considering tubular.

b0rn2fuck:
conversation between me and some selling and installing solar inverter system in my area, it's look cheap but I was worried about it capacity

Price is okay(its within range for a 1kva 100A system)

But generally wire is very expensive now. So my only concern is with the wire.

You can ask him to mention products he plan using it you want to further audit the quality of the the estimate.

He didn't mention somethings like changeover and accessories but there is provision for them from the estimate

solar installer needed urgently in warri..

Am available.
Do I send you a message

b0rn2fuck:
the inverter watts can't be more than 1000 watts. And what total loads can't this power

I don't understand your questions.
Can you rephrase

Filomena , chukwudumebi Chimuanya etc

We can only suggest its your duty to choose

psucc:
Ok.

Please do you have an idea of the cost

30a controller 7k
250w 65k depending on location 50-55k in Lagos
75ah battery 50k-55k range
Inverter 20k For modified sine wave
32k for pure sine wave
Wire location determines but budget 1800/yard for 6mm

psucc:
Thanks for keeping this thread alive. It is one of the few most useful for thread in NL.

My major challenge is to charge my laptop, if phone only would have gotten SUNKING product.

Based on your analysis below, what do I need to charge my laptop 65w/90w. Fund is an issue. Battery can be added latter since it will be used in daytime.

Thank you.

When I say battery can be added later, I mean the actual deep cycle battery can be added later..

Since you are on a very tight budget.

250W solar panel
75amps battery
30a solar charge controller
Inverter
Wire
This is basically what u will need.

b0rn2fuck:
the truth is I need one for my business, a watts total 800 to 1000, not to sleep at night, most between 10 am to 8 pm, does inverter store light too as I believe before that nothing work without battery, we are suffering for electricity challenge in ogun state except in area where they deliver prepaid meter.. I could go for 2000 watts inverter if they can work without the battery and how many panels with be good for that please with charger controller and type of inverter, I don't want to make mistakes, i have sunking home 600 with fan at home to sleep already,just something for my business as I have stop running business since fuel price increase,na sleep and spending the save up reserve..

There are inverters that operate on direct DC from solar panel but they are expensive and require a large array of solar panel to function properly (150v upward, with current ranging from 7A upwards) they are called grid-tie inverters

For your shop, you are better off getting more solar panels since most of the usage will be in the day time.

Besides panel are more cheaper compared to batteries.

Below is a picture of how a grid tie inverter looks like.

b0rn2fuck:
damn you meant , I can use light with solar panel, controller and inverter then I get the battery later., Maybe 300k budget can sort that out..

Yes you can.

keeper303:
Please I am in Abuja, which reputable shop can I buy new Jinko solar panels (545w). I am scared of sourcing from Lagos to avoid logistic damage to the panel.

I don't have contact now.
I can help you ask around.

As for the Logistics damage, if they are well packed, they will hardly get damaged.

You can inform your supplier about your concerns and they will attend to them

Welcome to the 2nd quarter of the year.

Success in our endeavours!

Happy New Month

atinga1:
Thank you, you've done more than enough. My budget was 400k, but I've decided to buy them little by little until I get all.
I'll start with the battery and then others will follow.
Thank you once again.

Start with the solar panels/controller- >inverter- >battery.
You can get them installed while you wait for means to improve the system to standard.

You might be wondering why I arranged then this way, battery is almost everywhere (if you want to go very cheap, you can opt in for vehicle batteries) only defect is this batteries are not designed for deep discharge and there lifespan is around a year.

Your welcome.

Your welcome.

forsaleitem:
Thanks so much for wonderful job you are doing here

For 100w load, please can someone use single 350w or 400w panel to charge 100ah battery to make the charging more faster?

Also, between tubular battery and lithium battery, which one do you suggest?

Thanks

Yes it's very ideal.

If you are starting out on this solar system journey, oversizing your panel has massive advantage.
1. Your batteries charge faster
2. You run your load on the energy from your panel.
3. Battery life is improved.

The 350w panel can provide sufficient power to run the 100w load in the day time.


Lithium battery is the best in the market, but na money kill am. .

michaelok:
I want to also combine IBEDC with Solar, but I am already scared of the cost, cos I don't have the total cash at hand. Kindly assist with the best cost analysis

1 55" TV
1 Industrial 26" standing fan
1 Gotv and Hometheater
1 Freezer (I would have to alternate with the standing fridge)
1 6kg Nexus Washing Machine
6 energy saving bulbs
Few charging ports for phone.

Every other things stays off.

Cost please and any monthly payment option.
0912 373 7617, Ibadan. Rented Apartment

A 5kva would be ideal for the load you mentioned here.

Your budget would be around 3m+
Batteries will cost almost 1m
Panel 9pcs would cost around 550k+
Inverter would cost 250k+
Wire,battery Rack etc may cost around 200k

For the installmental payment, there are companies that offer thst but I have no experience with them so I can't recommend any. You are better off getting the items gradually and setting them up.

I will advise you get solar panels first, they are quite cheaper compared to batteries And the are the life line of the system.

I hope you find a way around it.

Do you still have pure sine wave sachet inverter?

How much is 1000w

cleantitleautos:
Please which is better 5kva/24v or 5kva/48v? What are the pros and cons of each. I understand the 24v uses two batteries a time while 48v requires 4 batteries per time

I usually prefer 48v 5kva.. .
Merit
1. The higher the voltage you operate your inverter on, the lesser amount of current you draw from the battery.
2. Ease of operation, most heavy duty systems runs on higher voltage because of the above condition I mentioned
3. Your batteries don't over work themselves

Con
1. you tend to spend more money getting more batteries, and solar panels


5kva 24v
Merit
Less battery (2pcs), less panel

Demerit
1. Much current is drawn from your battery, this might affect your battery cycle life

This is basically the major difference

[quote author=aghaibiam post=124119629][/quote]Nice.
He probably would/may mention the SPD.

Enjoy uninterrupted power supply 🤗

Chairman, I need something for 5pcs of 10w bulb, fan and TV only. Can you please list what I need to buy or my budget? I'll be grateful If I can get an answer from you. I stay in Lagos.

A budget of 600k is very ideal.
200ah battery quanta (210k)
250W solar panel *3 (50-55k)
1kva puresine wave inverter (65-75k)
Breakers,change over and accessories (20k)
Wires (10mm2 is 3000/yrd (warri here is 3k not sure how much it is in Lagos)
Solar charge controller pwm (60a 25k-30k)

But if you want something functional and want to cut cost,

You can go for Starplus tubular (used to be 140k -150k range)

Get modified sine wave inverter satchect inverter (20k you can place order on konga and get it) problem you might face with this inverter is that your fan will humm(it creates distortion in Inductive load)



Solar panel remain 250w *3

Charge controller the same pwm 60A 25-30k (if you have the means opt in for mppt 60A 56k) there are verified sellers on this forum you can get from them

This would cost you roughly 450k -470k.

Please provide the size/type of TV (how many inches).

For the fan I would assume you're using ceiling fan gaint 60"

[quote author=aghaibiam post=124113009][/quote]Please what kind of fan and what type of TV(how many inches tv).

Good evening.

Sorry I didn't quite the right message

aghaibiam:
Off I went to the Market today to see if we would be able to arrange an inverter for the house.
I only told my husband, whatever we settle for must be able to carry our freezer.
My husband is an electrical engineer so he designed the power requirements of the house so we have an idea of what we were searching for.
Budget 1.3m tops.
We settled for a store we saw on Jiji with reasonable price, called to find out if the store was open since it's sallah and located the store.
We were able to get the following.
4kva/48v microtec inverter ₦290,000
4 nos 220ah/12v lotion battery @₦160,000 each making ₦640,000
6 250w Canadian fairly used panels @₦58,000 each making ₦348,000
1 60S mppt charge controller Felicity ₦115,000
Battery rack ₦20,000
20m 6mm DC cable 40,000
Total spent ₦1,453,000.
Transport 14,000 to my house .
Tomorrow the installer will be around to start installation.
We negotiated 50,000 workmanship.
He will come with panel sittings and screws
.I intend to use the inverter on 15 energy saving bulbs.
1 50" tv.
Phone charging.
4 ports.
My 200l freezer inverter freezer/ medium fridge.

Nice .
The system Sizing is okay for a start.
Consider adding surge protective device (SPD) and circuit breaker in case of short circuit or unforeseen mishaps

Kudos.



Go solar live better.

I'm currently in mowe Ogun state, where can I get the item, this Tinubu administration is on currently buhari promax, except person wan face hell na him he go try outside now

I dont know any seller or shop in Ogun state.
Your best bet is to source these items in Lagos state and send it to your location or alternatively you can hire the service of an installer.
