not true, as at this moment lithium is cheaper than lead acid. the average lead acid is 350k up, so how is it cheaper than lithium?

Can your battery be paralleled?

Assuming one go for 48v 105Ah now, after sometime the person decides to buy another battery pack like 48v 100Ah.

Can both battery be paralleled to get 48v 205Ah?

jonescosmos:
Unfortunately there is no known brand as PZ, I found out this website with their office in Benin City, Edo State https://www.pzenergytech.com/

This is just a rebranded Voltronic Entry Point Inverter. I'm afraid you might not be able to change any settings on the unit.
Please contact the seller or the company via that website to provide support to reduce the charge rate.

That PZ Inverter looks like Grovolt Amuma Hybrid Inverter, many clones everywhere.


@nicodemusic, you can reach them via:

jonescosmos:
Nope.
SPDs are attached to the PV inputs and AC input only.
AC inputs and Outputs, PV inputs and Batteries all have breakers respectively.

Would you have advised otherwise?

No

isangjohnson:
6 people.
500w max during the day and 300w max at night.

Is 500w usage per hour or accumulated daytime usage?

For how many hours will they systems be powered on?

isangjohnson:
Oga TechGeek777,
Please come and do this business analysis for us.
If 9m is used for the installation, how long will It take us to get our money back at the selling rate of #200 per kWh?

Boss, you want set me up abi?

I fit try help small shall.

Kindly tell me these params:

How many individuals will be using your service(Energy)?

How many KWh will they require per hour at least?

What's your total Energy supply capability?

jonescosmos:
The picture has all the details. But since you asked.

PV is 15KWp (16x 600w Canadian Solar Panels. 10x 540w Felicity Solar Panels)
Inverter is Deye 8KW EU Model x2 in parallel
Battery is Felicity 15KW x4 in parallel though capacity test topped off at 13.5KW. So I have 54KW Battery literally.

This is 90% of total capacity which is quite fair.

Did you use SPD for the inverter AC Output?

Valto:
i meant ABOKI black market rate bro.

The screenshot I posted was official rate, I know black market must be different.

dbshaywhy:
Growatt state that
2 awg for battery input
8 awg for pv ń ac input and ac output.

What O.P posted was Growatt SPF 3500 ES, O.P you can use these wires:
Battery 4awg/25mm²
AC(Input & Output) 10awg/6mm²
PV = 12awg/4mm²

For Growatt SPF 5000 ES, use these wires:
Battery 2awg/35mm²
AC(Input & Output) 8awg/10mm²
PV = 12awg/4mm²

Note: Depending on distance ( > 50ft), you can use 6mm² for PV Connection which I will recommend if money is not an issue.

Valto:
that was yesterday. dollar is back to 1520

See for yourself, screenshot taken @6:41PM

There's massive crash in dollar rate to naira.
$1 = 1,370.49

Longi Panels to reduce price if its panels.

Renewable Energy will become more affordable is this continuous.

Penuelseun:
@feflo sells 48v 800w victron standalone inverter, note that it is only inverter without charger

Am sure the amount of this will get him 24v 2kw hybrid inverter with high Voc and some change for cables, breakers and surge protectors.

jasp12:
@parser @TechGeek777
Pls where can I get this inverter to buy?

Ask @Zeestone99 or @Valto

Obnoxious2001:
This SMS inverter you get plug whey dey sell am?

Ask @Zeestone99 or @Valto, they have posted it here few pages back and I have seen some YouTubers put the inverter to action and it performed accordingly and also it batteryless function didn't disappoint.

Note that you shouldn't load it more than 80% of rated capacity.

Even a user posted few days ago on how they fixed his SMS inverter for him under warranty and even apologized on top it.

Repairs is the reason some people fear hybrid and also it's like putting your eggs in one basket 🧺

TBH hybrid is the way to go, am not saying Standalone is bad either but few points have been stated above on its merits.

isangjohnson:
I'm learning from my boss, Valto .
I didn't ignore your message intentionally. I'm sorry Boss

No problem boss

Thank God the ministry is moving forward.

Am happy for you bro.

But you like to ignore my messages for backyard shall

Sapiosexuality:
VOC? What does this mean? How do I know where mine stands?

Open a new tab, go to Google and sometimes ask search engines for clarity sake.

Search for these:

Pmax
Voc
Vmp
Isc
Imp

ojeysky:
Can you provide reference to the seller at this price?

Na typo, I think Zeestone99 and valto has posted that inverter before.

icjunior:
This SMS inverter is entering my eyes o, please is it a good brand? if it is, can I upgrade from my 2.5kva smarten inverter to this SMS and still run my powmr 60a mppt on the SMS inverter?

The word good is related to how well you pamper your inverter.

It's an hybrid inverter with high VOC(450v) pv input.

You can use your PowMR CC, based on the number of PVs you have and the configurations.

Goodmorning house

Please need advise
I want to purchase inverter and solar panel
This are appliances I want to carry
Fridge
1 Ac (inverter)
4 fans (regular ones not industrial)
2 tv
Sockets
Light
Which will be regulated


I was told to get 5kva hybrid inverter, 2 tubular batteries , and 6 (300watts) solar panel

Please need suggestions on best to use as I’m on a budget and don’t want to spend more that 1.2mill
Also is hybrid inverters with inbuilt mppt controller better that normal pure sine and separate mppt controller ?

Although the HP of your AC wasn't stated, but if you can up your budget to 1.8m, you could get the following:

24v 3.6Kw SMS Sunmate Inverter 350k - 400k

24v 105Ah(2688w) LiFePO4 Battery 650k
Expected price according to Valto from previous response.

Jinko 435w * 4(1740w) 480k

Installation, Cables & Accessories 270k

Above are 1.75m - 1.8m

UPDATED

Ogidi1991:
Goodmorning everyone

Please is the sms summate inverter a strong and reliable brand
I’m planning to purchase the 6.2kva hybrid inverter (MPPT 120A)

The bolded words are relative.

Don't overload your inverter more than 70% - 80% max, install AC & DC MCBs, AC & DC SPDs, earth the inverter at least even though you don't earth the panels and don't abuse the inverter surge and you will see your inverter last longer than expected.

Drgreatone:
U need battery connected to it regardless. At least for the sms. Tried it and it kept going off anytime the solar output went low/off

Not just SMS, any inverter will go off if the load is more than what the panels are producing.

Ferdiwar:
Please can you assist me with the spec sheet of the 625w panel you got.

I am working on expansion of my setup but the Longi panel I'm currently using is annoyingly expensive now (208k for 570w as against 165k I bought them in December).

I earlier went with the Longi over Jinko because of the current as the max current of my inverter is 13A, the Longi 570w have a max current of 13.03A while the Jinko 580w have a max current of 13.38A

I believe Isc is 13.92A @STC

dbshaywhy:
Noted, thanks very much, but you only stated for 24v, is 48v not advisable or a waste,

Cc. Valto already flagging 48v 105ah lithium battery and a 6.2kw 48v hybrid(I think this is China product, hopefully it's durable)

I stated 24v 3.6kw for the following reasons:

1. You said your load can never exceed 360w

2. Your budget can't carry 48v 6.2kw.
This inverter and your planned 6 * 550 jinko panels will take 1,519,600 and you are left with 680,400 and it can't carry battery let alone other components.

You may have to reduce your pv from 550 to 435 * 6, if you are to work with your budget of 2.2m.

But ask any of the above mentioned names if 6 * 435w jinko can effectively charge your battery.

dbshaywhy:
Thanks for your input... Am not always at always during the day from Monday to Saturday, except Sundays.
With my rough calculations, instantaneous load in the when back can never exceed 360w, while over the night, 80w with century rechargeable fan(mains will be on wen notice its getting low)

My budget 2.2M

Hybrid is your choice here, work with @Zeestone99 or @Valto to give you a reasonable quote and inverter within your budget.

3.6kw SMS Sunmate inverter could work with your stated load and even accommodate near future expansion but don't load the inverter more than 70% of it capacity at any given time to prolong it lifespan.

Your hybrid inverter should be any of these based on your budget:

3.6KW 24V SMS Sunmate Inverter
3KW/3.3KW 24V SRNE Inverter
3KW 24V Felicity(I don't know why this is dangerously high in prices now).

dbshaywhy:
My plan solar system set up.

48v system

6pcs of jinko-solar-550w

3.5kva inverter, hybrid or stand alone with cc
(can you please recommend a good brands from the choosing option)

5kwh lithium battery

Professional in the house, I need your input...
@jonescosmos

@Techgeek777

@dollarnaira
@other professionals in the

Please, I need this urgently before price shoot up again please.....

State, you total instantaneous load, budgeted amount for battery and inverter, it will go a long way in advising you.

Ferdiwar:
Mid January when I wanted to mount my panels on the roof, I contacted (a so called) engineer to do the Job (I have phobia for height), via phone call without any information on my setup baba concluded that 5 pieces of 570w panels won't work, that it's either I get another panel to make 6 or I use 4 out of the 5 and that I need 10mm with for the installation I just ended the call and reached out to another person.

The guy that later did the Job later begged me to teach him how to set up lithium battery on the inverter as he was unable to do that on the 1st Deye inverter installation he did.

Most of the installer and so called engineers are too lazy to update their knowledge on the same things the practice.

Maybe him think say na parallel connection.

The second guy is humble.

Humility pays.

isangjohnson:
I did and the boy told me he set the hybrid inverter lvd to 48v and the battery type of lithium.
That was my essence of monitoring the installation through calls.

My brother, next time use WhatsApp video call and ignore regular calls(audio).

What you saw is better than what you are told!

isangjohnson:
There is a member here named Bekas, who hasn't met me before. He got my contacts here, called and linked his friend to me who transferred complete money to my account to couple 48v 280ah lithium battery for him last week. I did way bill for him to Akure yesterday. I gave him two years warranty and I would monitor the installation to make sure everything is done correctly.
That's what we called trust.
Yesterday, another member here transferred money to my account for 24v 160ah to be delivered this week. That was trust as well.
If people I have not seen before could trust me with their hard earned money and I've not betrayed the trust, what would stop me from
trusting others.
If I pay you good and you choose to pay me bad, I leave the judgement to God.

People forgot who you know is better than what you know most times.

Most people don't leave judgement to God these days, especially if the opposition is hell bent on not delivering.

There's a reason people fall ill and recovered from it and others lost they live because of little headache.

Always treat people right, you never can tell who would decide your existence tomorrow.

I believe any good transactions will always bring more transactions!

Valto:
fouani price is updated according to new dollar rate
gennex still selling according to former increased dollar rate. they will soon wake up, but might be too late for them

Dollar is now 1531 @ official rate compared to 1637+ as at last week.

It will keep going down.

Sellers should use they brain to sell goods and not waiting for too much profits.

Valto:

Nigerians are quick to increase prices.

Fuoani is becoming more popular when it comes to Pv purchase.

With the current economic state, naija needs quality products that's not a too expensive.

icjunior:
There is a huge disparity in prices of jinko panels between Gennex and fouani.

Gennex is not aware?

475w on fouani is 144,900
465w on Gennex is 172,500

No mind Gennex, make them dey play there.

Them go say na when dollar high them buy the PVs.

Fouani all the way at the moment when it comes to Pv purchase.

Youngzedd:
Are there any non Chinese lithium-ion battery brands in Nigeria?

I just don't like felicity that's all over the place.

Discuss with, any of them to couple battery for you.
