Good morning!

I remember sometime ago, someone was interested in buying a 3.5kva inverter

A customer is looking to japa and needs to sell his 3.5kva 48V soccer power inverter, used for 15 months.

Please if interested, kindly quote this message.

I do not much experience with Schneider with fronius but I believe the AC 1 is the primary source of power output from the inverter and AC 2 would be meamt for auxiliary output based on certain conditions.

Under an ideal case, since the aim is to form a mini grid with the inverter then having them meet on the AC 1 is the right way to go.

Nexuspulse:
Hi everyone, please my colleagues and I are having difficulties at arriving where the output of Fronius Primo PV Inverter 8.5–1 with a Conext XW + 8548 E should be connected to (Meanwhile, it is connected AC 1. There is a space for AC 2) I have attached picture for your perusal. Thank you.

I'd check for some and revert back.

Kindly remind me incase I am immense in personal activities.

oloet:
Please can you connect me with the cheapest one available

You will need an external LVD device that does the job for you, that way you won't have issue waking up the battery.

oloet:
My inverter is dumb that the BMS shuts down before it, quite sad....

Bus as in on the BMS itself or at the charger/inverter side.

oloet:
Does this apply to a BMS that uses same bus for charge and discharge

Well said, a friend just got marriwd recently and he get plenty story to tell.

Who ever think marriage is rosy is delusional.

This is why it is better to go for someone that at least gives a form of peace of mind or prospect you'd expect.

Xpol:
You see this marriage of a thing is just over hyped, the excitement of getting married doesn't worth it. a lady and a man living a free life doing what they love to do without any questioning, a man that drink for instance can still be in drinking bar till 12am till he comes home, a lady can also go out and comes in at will but once married all or most of those things are supposed to be thrown away but it doesn't happen like that. As a bachelor you have so many characteristics you want your future wife to possess but don't let me deceive you, you can't get a woman that'll have all.
If anyone claim to have it all she's likely to be a pretender. If you ask.

Do this Assignment before getting married. Ask 100 married men, if that's too much for you just ask 10, first beg them to be very honest with you then continue to be asking them questions about marriage.do the same with women.

You can just do as if you're doing school research and don't let it be people that knows you coz they won't tell you the truth. Don't do it around your area.
Na manage everyone dey manage no fully happy married life is very scarce.

Women thinking and reasoning are entirely different from men own. If you see a marriage of more than 5yrs that the man has never beat his wife just know that the man is able to control himself not that the wife has never insulted him.

After getting married misunderstanding will always be coming, things hidden will be revealed on each side, see finish will also comes in, the man will like to be in full control which it's hard to get.men go into marriage for many reasons of which full unrestricted asses to sex is mostly part of it. So anytime he's being restricted triggers some kind of negative thinking from within...............

You can court for 10yrs but you'll never fully know each other until after getting married............................

Sad! Well you have your reasons, but not enough to loop a whole bunch of gender based on a certain experience.

I'd leave you to do your thing, Have a great week ahead.
If you change your mind, do reach out via the mail.

Chee59:
Unfortunately I have decided to never have anything to do with nairaland guys.

If this scenario was to be the case, and your BMS was properly configured to prolong your cell life with recommended settings then only the discharge part of the BMS will go off, while the charge part stays on.

when you need it to charge, it will receive the charges fine.

oloet:
Shutdown as a result of completely drained battery

A BMS would completely shutdown in certain conditions, at other times they would keep working.

1. If the charging voltage is high and the cell voltage reaches the cut off voltage then, it will either shutdown or just cut off charging there by making the battery still available for use as only inverter. (i could be wrong, as i have less experience with DIY LITHIUM)

dacool1:
Thanks.

I was wondering what would happen should BMS shut down in order to protect the battery.

You can replace nnamdi with my name and it could be a beautiful beginning.

what say you? Happy weekend

Chee59:
This should have been Nnamdi and I.

Some charge controllers have been known to go bad while some do not.

But under what conditions are you looking at that will trigger such response?

dacool1:
Hello house, I've got a question. What happens to the charge controller if my battery disconnects from the charge controller while PV is still connected?

You should try Pylontech

Xmen149:
Please can anyone recommend rugged lithium battery with good efficiency..am looking at 10kwh to 15kwh

Thanks all

Are they now faulty? Because those bought by customers are still going strong till now.

tonididdy:
I bought 2units 26k then

The purpose of it's selling/recommendation is only to bring about energy conservation in homes or offices and a shift away from standard fans of higher consumptions.

mctfopt:
This looks cool, why are you selling?

it was sold for around 14 - 16k around 2020

tonididdy:
Lol that’s the price I bought 2 units some years ago now.


Una country don truly spoil oh

This is their Version 3

From the test on their Version 2. The max. Speed was doing 10.6 - 11W max.

The highest speed is enough to equal to a standard standing fan speed 2.

Most fans use aggressive method to pull air to blow outward I.e. more energy consuming but this fan use I guess a modified fan groove that allows for gentle breeze yet cool air outflow.

dollarnaira:
Current will be around 0.84A extremely nice at highest speed possibly.

But pls bro, how is the speed like?

24,000

With a year warranty

tonididdy:
Please what is this cost now?

I will get back to you on this shortly but can you put the wattage either total of them all or individual item with their numbers of loads or appliance

tolukemi:
Here are my estimated run times:

1. lights - About 6hours during the night.
2. Four ceiling fans - 2 running from 6pm-6am
3. TV with decoder - 7pm-11pm
4. Refrigerator - 7am-7pm
5. Chest freezer 7am-7pm
6. Water pump - 1 hour during the day
7. Possibly an AC in the future - 6pm -11pm

It is good that some of us have ideas of the importance of RCCB in our circuitry

At some point in journey of our installation, it was incorporated into system installed but 95% of homes failed the integration thereby making it useless in the long run and was abandoned for other means.

Most homes lack properly done earthing which a RCD may not overlook as the resultant leakage will just trip it ever time.

Till our local electrician gets things right, professional solar engineers have a long way to go.

If only men know the damage to which exposure to sexual immortality has done to their masculinity generally speaking or the distraction from being at their best and Also the programing to which what we see and hear.

Then trying to shy aware from some of these decadency can sure makes one a better version of there self.

ThunderStrike:
The number of sexy women one is exposed to on these sites per hour, an average man in 1946 didn’t see a tenth of those number of laps, nipples and boobs in his lifetime. The brain is being damaged. We are being distracted. What is the agenda?

Before proceeding.

If you have the time, can you share you load run time here.

How long you want them to do run during the day & also during the night.

Before you finally returning to the quote provided

tolukemi:
Hello everyone. Please can you help me critique this quotation (parts and cost) I received from an installer? Background: I am looking to go off grid as much as possible. I need to power the following:

1. lights
2. Four ceiling fans
3. TV with decoder
4. Refrigerator
5. Chest freezer
6. Water pump
7. Possibly an AC in the future

Here is what I have been quoted:
1. 5KVA/48V Lento Inverter ₦500k
2. Four 220AH/12V Lento Tall Tubular Battery ₦190k each
3. Battery rack ₦19k
4. 2.5mm cable (15m) ₦1.1k/m
5. 60A Adjustable voltage protector ₦30k
6. 32A AC breaker ₦3.5k

Thank you in advance for your help.

Try cloud energy Dc fans, they come with AC adapter to use with normal wall outlets or using a 12V battery or DC powered setup - power consumption is 11.8W for older series and the new series claims to be 10W.

Give it a shot

ebocoms:
Good day All,

Please I need recommendation for durable low wattage Standing Fan not more than 50W.

Thank you.

My experience with them hasn't been positive that justify their use, anyway those were the older version.

My experience is just minute compare to others with good results.

So I won't air it, others can share their experiences with it.

FYI "it's the external black thingy"

mangolpupa:
Thanks bros for your response. first picture is what i mean.

I couldn't figure out the "black external things" you described.

AGM batteries don't require equalization only Tubular batteries does except it is those black external things for each battery you referring to here.

mangolpupa:
House almost on the verge of biting the hybrid inverter bullet which comes with in built mppt charger. so no need to get separate mppt charger.

however my question is do i need to get a separate battery equalizer added to the solar system (its a 48v AGM battery configuration) or is having the "all in one" hybrid inverter enough.

Stick with the 3 units of panels ...

henro4niger:
Thanks a lot for your response, it will go a long way. Just a side note, I have day light load, a 120watt inverter fridge, I want to run it from 10am to 3pm everyday.

Bro if you can safely remove the diode that's faulty, check the info e.g. IN368 - Google search it and download the pdf file.

Them head to your local hardware store and buy equivalent diode that fits the voltage and current curve of the present diode.

you should be good..... also better to snap the diode before removing to ensure that your replacing it back to the original position. [quote author=Forrkke post=119856720][/quote]

Ideal solution will be

500VA Indian Inverter
30A PWM solar charge controller
100Ah lead acid or lithium battery
150W x 2 solar panel

A fair price can be used to have it constructed.

i am sure many others can chip in their ideas to help you out.

longyemi:
Thanks for the response.
The TV is 80w
Decoder is 20w
Fan is 80w if you substitute this for a DC fan (10W) from cloud, it will be mighty helpful
Sound system is 60w too if its really necessary to add this then by all means use it, but you can remove it and free up some energy space on your battery.


To be used for about 6 hours during the day and just lightings of less than 20w at night for 6 hours too

This is for during the day while the sun is there because I still have to run a big gen for my freezer at night.

I will have loved to recommend my company but for the sake of picking the best fit for your needs

Can you give a brief summary of what needs to be powered so that you can get contribution from experienced hands before settling for your choice

Installations are never with static design and sometimes requires unique design to fit your exact needs for desired result.

fizzyf4:
Please I’m still in need of recommendations, location is lekki.

Check bolded replies

henro4niger:
Hello house I got the following quote in abuja:

Genus Heiwa Series Pure Sine Wave Inverter 1625 VA 12V = 125k
Felicity 45A MPPT charge controller: 70K
[s]Africell solar panel 300W, 3 units 75k each: 225k[/s] If there is no day time load, i.e. maybe a 9-5 person & with Nepa charging (if stable) then reducing the panels to 2 units is fine.
Solar profile: 5.5k
Dual core 10mm cable : 1.8k per meter
Genus 230AH tall tubular batter (buying only single unit for a start): 180k
Labour: 20k
Total is about 645k

Every thing checks out but the installation didn't show likes of Over current device and Over voltage device which will help safe guard your installation.

Guys, please I need your input here, is there any unit I need to add or remove? is the quotation ok? Please help a brother. If anyone in abuja can give me a better offer, I can consider it

Over 15 pages read, omo no be here.

Happy new year to all members, una well done with the contributions more power to your elbows.

Pray the new year brings new accomplishments and success to us all.

NoC - means "Normal operating operating conditions"

This is what your solar panel would deliver in real life ... And so for your 1800Wp panels quoted, it will average 1KWp +/-

So if your pump is on, yojr battery js needed to support.

Pojomojo:
I don't understand the bolded.

Lastly for your panels if you do 400W+ it will be helpful especially for your pump, as even 400W x 6 = around 1.5KWp under NoC.

400W was suggested due to his pumping machine to at least get enough power from the sun to the pump directly when needed without taking from the battery.

And a 2400W would average 1500Wp +/- depending on the available irradiance of the sun.

Hope this helps?

IyaTola:
Why? 400 and what was quoted was 1.8kw yours is 1.5kwp is there any difference
