EPOMA:


Have Felicity started doing the full capacity as they advertise . I stayed away their products years ago for selling undersized Batteries for wrong capacity. I don't like dishonest big companies . I rather build my batteries

I prefer factory built if the price is appropriate and the cells are grade A. I'm more comfortable with their packaging, warranty and after sales services

Valto:
u will know if they have repented, by the current price of their lithium batteries

Lol..
Is the price higher now or lower?

coldcandy:

Lol..
Is the price higher now or lower?

your guess is as good as mine

Valto:
your guess is as good as mine

I can't guess. I'm a newbie in this business

Top BMS, has anyone used it around here?
Hopefully it balances this battery.

NiyiOmoIyunade:
The answer to this seemingly simple question is 'it depends'

A lot depends on the particular mix of equipment you have.

Yes you can connect individual 12v chargers to each 12v battery (or parallel 12v batteries) in a larger 48v bank for example.

The specific algorithm depends on many factors but your goal should be that the inverter and solar chargers are charging at a lower voltage than the individual 12v chargers - you basically want the standalone chargers to complete the charge.

Now where are you powering the chargers from? Mains or Gen no trouble, from thesame inverter AC out as the batteries, then you need a mechanism to cutoff the standalone chargers in case Mains and/or solar becomes insufficient - basically you cannot use the batteries to charge themselves!

If your inverter is pure sine wave you can generally power the chargers off the inverter AC out, modified sine wave inverters may not have the AC and DC sides isolated and may short out.

So in most cases you can add on standalone chargers without trouble but you need to be sure your equipment supports it.

A good quality adjustable voltage smart charger is not cheap so your battery pack should be large enough to merit such effort and expenditure

All clear, thanks !

NiyiOmoIyunade:


Measuring idle/no load draw is a bit of a misnomer since no one just keeps the inverter on with zero loads -

The point being made about idle consumption isn't due to what you described above, it's due to the additional burden of self consumption by the inverter.
I believe that's one of the reasons some people here complained about MUST inverters. We're trying to be energy efficient as much as possible so is it really a misnomer to seek inverters with better efficiency?

TechGeek777:


Boss you are very correct, I contacted them yesterday and was told it sells for 123k and warranty is 1 year. Do you have idea if credible sources price are lesser?

Why is Jumia seller placing 170k on something of 123k. Naija which way!

Are you sure it's 123k or rather 132k ?
Please confirm.

Juror:

Are you sure it's 123k or rather 132k ?
Please confirm.

It is 123k confirmed.

There is a difference between idle/no load consumption and the inverter self consumption (energy lost or used by internal components when inverting DC to AC).

Most people obsess over the idle consumption whereas they should be more interested in the self consumption when the inverter is actually doing work - this is not linear and varies based on loads.

The problem is not helped when most users heavily oversize their inverters e.g use a 5kva inverter when loads are within 1kw on average.

this voltages are too high for lifepo4 cells, pls confirm your battery is lithium ion, and not lifepo4!

which inverter are you using that works with such extreme voltages

i do hope you know what you are doing!.

if lithium ion...you should have 14 cells...that way the voltage is within what most inverters can handle----below 60v
if lifepo4, then the 16 nos quantity is correct, but then the voltage is wrong.

kindly review your setup, b4 you damage something expensive

bbally:


please
(1) how do you do the active balancing?
(2) what is the load on your battery to preserve the battery at 12.9v with load?

1. D device connected do the job
2. I do dis job here with a corner eye.
I shut down my load as I hit 12.9v though lowest discharge is cool at 12v.

WE BUY DEAD/SCRAP BATTERIES!!!

It's lithium.
Also it's for electric bike 60v 40Ah
I've been using it like 8 months now and about 3 months without BMS, decided to get the BMS before i damage it.
Hence the reason why the battery has different voltages.

Please I would like to reach you. I have an ebike with a 60v ~20Ah battery but giving me trouble after a few months.

Hopefully I may be able to leverage your experience to fix and upgrade the battery pack.

It is 123k confirmed.

That's odd, I got the 132k quote this morning also from them or isn't it the FL-IVPS1512 , 12V 1.5kVA?

The toroidal transformers are said to also have lower conversion losses, hence more efficient too.
Because the standard transformer inverter is already consuming about 50W just to stay on, then goes ahead to add more overhead via loses during conversion.

I don't know the model number but I believe if they have more than one inverter of the same specifications, I would have been give at least two prices.

You can call Michael, his number is in the screenshot.

You are very correct, this is the inside of my old inverter, the tbb 24v 0.8kva

Okay you can drop your WhatsApp number, I fix mine myself and buy parts from China. I have 2 currently and they work just fine.

Right now it's hard getting original batteries, all you see around are fake and used. The person who sold me the batteries I used to build mine ran out of stock and unable to get more into the country due to shipping restrictions.

Good day all,
please i need some who can repair 3kva hybrid i power inverter. it does not supply energy when on battery or solar but only supply when there is public power

Are you sure it's 123k or rather 132k ?
Please confirm.

My brother 100% sure bro. That's the price I was told. But today around few minutes to 4pm, another of they sales rep chatted me and when I enquired again about the price, she said 125k, but I told her that's not the price I was told, that I was told 123k.

Then she requested I send her the number, behold when I check the number she used in calling me I found out the same number called me two days ago but I didn't save it as there are hundreds of calls after then. She said that's an old price that her boss gave me wholesale price.

But am surprised why her boss will not know the current price.

But she pleaded we continue the conversation tomorrow as she has closed because it's now pass 4pm.

Juror:

That's odd, I got the 132k quote this morning also from them or isn't it the FL-IVPS1512 , 12V 1.5kVA?

I didn't ask for series. I only asked "how much is the current price for 1.5Kva inverter"?

And was told 125,000.

If they are telling prospective clients various prices for same item, then what Oga Valto said /guess about they lithium/Lifepo4 battery might be correct!

You see, it's 123k I was also told, but the female rep now telling me 125k this evening.

Sometimes the fear of women is the beginning of wisdom.

Even though 2k different is not much, but it says a lot about top brand.

u should take it easy with the rep. they work according to instructions given to them. btw, because of present realities(inflation, foreign exchange e.t.c)prices of goods can change within few hrs, talkless of 2days.

Guys, please I need help.

Don't even know how to go about this.

My budget is 300k- 400k


What can it get me, and who can help me with the installation?

How do I know if I got original/good batteries and panels?

Advice needed, please
