I don't think this will work. The voltage of the panels do not match except you will be willing to buy another charge controller.

Hello house, good evening.

So I have a setup of 3 pieces of 250w panels on a 1.5kva inverter and 2 batteries, but it doesn't charge fast enough with the panels, I figured that it needed more panels and someone is offering me a brand new 520 wats panel at a good price, however, I refused buying cos I read that joining panels of different wattage together is not a good idea, however, I went ahead to ask my installer if the panels can work together and to my shock, he says they will work fine. I am sceptical about it and don't trust his judgment on this one, so I decided to ask the professionals in the house, what are the pros and cons of joining panels of different wattage with such wide margin?

mctfopt and anyone that cares to help. Thank you.

Provide us with more information
What's the voltage of the previously installed panels and the new one
What kind of charge controller do you currently use. Give us the specs

Don't mind all these kids here on nairaland. Don't give up on your ideas. I just think she's having a wrong mindset thinking it's a control mechanism or she lacks indepth understanding of the subject matter or she's selfish. Forget all these independent talks from people here.

How is she independent when she will be controlled by a coy, she prefers to work for other people's organization than to work for her family. Most women have this problem.

If she doesn't understand the pros and cons of her decisions, try educating her but if you sense she's putting herself ahead of the family, you will have to appeal to her selfish nature by making her see from how it benefits her more.

It's most likely she wants to have some level of freedom to move around without getting queried. If this is the issue, just plan your retirement without her in the picture for now. When she's about 50years old she'll come around.

For those saying she needs more income, what's the income going to be used for. I hope you all read where he said all expenses are catered for by him. Plus she makes more from her current business.

So sad. Been downloading movies of good quality from them. Guess content owners Don press their neck for piracy

de3lar:
Yes I don't have appliances pass TV and Light bulbs, the rest are phone chargers.


For other heavy loads, I have a big Gen to power them if I wish.

OK then
Panels 160k to 200k depending on type
Battery like 350 to 400k
Cc like 20k
Inverter 66k(sachet) because of low power consumption and 1500 watts is an overkill for just TV and lights I would recommend 500watts to 1000watts
Cables etc 50k

de3lar:
So I'm planning on going off Grid and off Gen, I need the cost breakdown for these setup:

4 150w solar Panels
200ah Lithium Battery
30A Charge Controller
1500w Inverter

Anyone with the average cost should please help with their prices 🙏🏾

Thanks.

You can't go off grid with those listed above. Abi it's just light and TV u want to be using ni

ameh99:
50AH 12v lithium battery available?

Price?

Ymguitarz:
Please guru in the house, how much will be enough to setup a 3.5kva solar system. All expenses plus installation.?

5million

Fear God na. See what u want to sell for 40k

Stop praising nonsense. Even more advanced countries still make use of physical files, e get why.

It should have been categorized that majority of the works be moved online not all

helinues:
No wahala, na to stop providing service to those who refused to upgrade their prepaid meters when the time given lapses.

You people can go to court. Sebi una wan dey play politics with everything

Don't you think you are deliberately being foolish here. No matter how much you are paid to defend these people and policies, you don't need to sound stupid.

So you expect people to give up their prepaid meters and get hooked on estimated billings because of the said upgrades. What about simply giving them temporary prepaid meters or outrightly replacing the said meters. It's like you have no idea how much this people rob us in the name of estimated billing.

Unmetered buildings in my area gets as much as 120k per month as energy bill. The minimum estimated bill where is stay is 55k per flat. If not for prepaid I would have disconnected too

Can't they simply go to the said homes and simply upgrade those meters and reconnect them. Is it beyond upgrading, even a whole computer self will be upgraded in less than 30 mins

complexstuffs:
Good morning gurus in the house,

Pls can gurus help me with quote to install a solar/inverter system in my house with the following load of 1500W.
In addition to the house load, I will also install 4 number batteries.

1) How many solar panels would I need and their sizes
2) What size and type of inverter would be best for this setup
3) What size and type of Charge Controller would be best for this setup
4) What size and type of batteries would be best for this setup

Thanks as I await your responses

Just go with mctfoot's recommendations
But you will just do fine with 3.5 to 5kva inverter
Up your solar PV to about 13 or 15 kw
And if you insist on lead acid batteries you will need atleast 24 batteries assuming the loads will be on 24/7 and managing the batteries will be a lot of work and you will need to dedicate a whole room

It's when you go solar you will realize that there are more cloudy days than sunny days.

why do you all believe he is dead. its all part of the script and i:strongly believe putin knows about this as the guy had to disappear after taking the west money without killing putin

the audio self sounds doctored. was he discussing such a sensitive matter in the public, the audio sounds layered too

first of most countries listed over there are not oil producing states, secondly they have better minimum wage than Nigeria. Let this people stop all these biased comparison e no make sense

temi4fash:
I noticed my battery discharge has increased astronomically.

Usually the Battery level do not drop more than 0.2v over night. But now i noticed it is dropping by 2.2v and up to 3V sometimes

Its not like the load has changed, it is the same load i use in the house.

Also, i decided to check the battery levels with a voltmeter and noticed one of the battery is 12.7V and the other was about 10V

What could be wrong and what do you advise i do?

The battery is an i-cell GEL Batteries,

try to charge them separately, see if there is an improvement but the 10v battery is likely shorted

GuestJoe:
Please,can someone help me look into this quotation.

Panels: STC,Rubbitec or Flames
Battery: Tubular (Addo or Houston)

This is to be used by a shop that runs from 8am-8pm and the total calculated load is 3.4kva

will the load be on simultaneously, if no; the panels will suffice else double the panel size

As for the economy mode the number of batteries is grossly underestimated. you will need at least 16 pcs of 220ah batteries

as for the lithium you will need atleast 17kw to 20kw battery.

you may not need that much back up if the loads wont fly simultaneously.

The number of panels will be seriously increased if you will run the loads simultaneously. To be totally off grid you would need would need a min of 32 400w panels

Oppsin:
That's what the man ss listed for me, how true it is as its difficult to trust anyone these days again?

you want to draw 500w from 360w panel. well it wont work. you will need a minimum of 8 pieces of 180watts panel and 4 220ah batteries incase of days with unfavourable weather.

Plus most of these 180 watts panel are actually 150 watts ideally you should have about 10 to 14 panels

you will be needing a bigger charge controller too

brightk:
i beg to disagree sir.

okay sir. its impossible for him to get beyond 2hrs. so far its a lead acid battery.

read about Peukert's law. plus he cant go beyond 50% DOD. 500watts out of a 220ah battery #12v no be joke. the battery voltage will sag so bad within minutes. That's over 50amps draw from one single lead acid battery

it will only work when the sun is up,t that's if panels are added

Oppsin:
I didn't understand the explanation, but will 12v 220AH battery be able to work for 7 hours using 500w of appliance? Thank you

I just had to add it as a note. NL no like numbers

7 what?? you cant get 2hrs self. you will need atleast 4 batteries for that except probably with solar energy complimenting, but on batteries alone, NO

pineed:
Simple answer is No.

why? care to explain. is it not combustible?

quick question..
when the CNG becomes available, hope it will be a suitable substitute for LPG??
Cooking gas dey chop money o. Its back to N750/kg in my area

solareclips:
Good day all,
Please which of these set up will last longer after full charged.
24v 3kva inverter, with 4nos of 220ah battery 2s in parallel, and 48v 3kva inverter , all same loads.
Thanks

Care to explain why

This your story no clear

A 12v solar array can't charge 24v battery

Let the masses breathe. People are already breathing as if they are on life support. This is no longer funny. In a couple of months there will be massive job cuts because companies are not meeting up their revenue generation because of low patronage.

Let the government put the foreign exchange in check. No serious government floats her currency. Almost all storing economies of the world controls their exchange rate to an extent

LLMG:
you mean like the govt sponsored anarchy. Please direct your advice and concerns to the govt on behalf of the the harmless and peaceful protesters.

Don't mind that slow poke. There should be massive protest against the government policies. They in no way favour the masses on the short run or long run.

I was shocked when I wanted to restock rice yesternight only to find out one derica sells for 650 to 700, a bag sells around 39 to 41k.Every other items also had increased astronomically. I just lost about 50% of my purchasing power in two months of this regime. This is pure evil.

The government wants the people to bear the pains for a better tomorrow but they are enjoying jumbo packages. Nigeria can never be good if we don't call a spade a spade.

Forget tribe or religion. Hunger doesn't discriminate o.

If any idiot quotes me and say double your hustle, I'll give it to you blue black.

Like play like play revolution Wan start. The government should be swift else I see this protest degenerating into serious crisis.

When the masses have a common enemy (hunger) to revolt against it is always serious

FreeStuffsNG:
Subsidy removal on petrol has come to stay. We will adjust with time and back to our winning ways as a nation.
God bless Nigeria for ever! Check my signature for free stuffs!

Same subsidy removal he vehemently protested against? Nigerians are too docile. It's morally wrong for him to remove same subsidy he claimed doesn't exist back then. He should first apologize to Nigerians.

Acekidc4:
Problems like this is Suppose to make the Citizens become Innovative and Creative in finding alternative Workable Solutions. This is a good time for we Nigerians to be Creative instead of waiting for government everytime. How many can government do for Us?? We can do a lot of things for ourselves by ourselves. Don't wait for government wey no send una Papa.

We should do alot ourself, what then is the function of the government, what's the use of the free natural resources? It's only in Nigeria people use their money to buy cables for electricity, buy transformers, pay for repairs of the transformers, pay to acquire meters and still pay for the energy.
Go to the police station to report an incidence, you get billed. What exactly is the use of the multiple taxation. To enrich themselves?

Simply because you and your kinds are getting paid does not mean you should be totally shameless. Your likes is the reason why Nigeria will never progress. Call a spade a spade.

We should endure pains while they enjoy luxurious lifestyle. Okay o, continue we will all voice out at some point.
