You didn't mention your load.

I haven't heard of LiFePo4 exploding
Most modern cc's have Lithium settings
If your inverter can handle 15V it should be okay
Babysitting/monitoring is far less on Lithium than Tubular/LA. I basically just look at my voltage anytime I pass my setup and that's it.

A properly fused and BMS'd setup shouldn't give you any issues.

Thanks @ gadgetplanetng for your response.
My load is fine during the day with...
- led bulbs = roughly 45w
- Tv and decoder = roughly 130w
- Refrigerator = 110w
- Washing machine = 500 - 600w
- Fans = roughly = 120w
- the inverter itself = ??

The solar do take care of these load during the day and still charge the battery full before 12noon.

My night use is mainly lights (50w), fans (60w) and phone charging. Total of roughly 150w

Less I forget, I run fully on solar i.e off-grid. I only switch to Nepa when fixing things on inverter system or once in 2 weeks to allow inverter to rest for a few hrs. Only my pumping machine and bathroom water heater is directly on Nepa/gen.

Also my soelix inverter is 24v and I will be considering 24v LiFePO4.
The inverter has a battery setting to select either smf or tubular, the main reason why I am in doubt if it's compatible wt Li battery.

If monitoring means just using the corner eye to check the reading while passing, then this is fine.

gadgetplanetng:


If the inverter doesn't charge the battery then that doesn't matter.
What matters is the CC and if it has the adequate settings

kaziem:


Thanks for being there.

That means I should not bother on the Inverter since I am not charging the battery wt Nepa.

Attached is the pics of my CC, I wish it is compatible wt LiFePO4 charging.

Also, I am looking at that tactel LiFePO4 brand like the one adrusa bought.
I am also open to any reliable brand.

I will also appreciate advice from other experts please...

You can define charge settings on that so it's okay.

Please when dealing with batteries never say you will do away with charging especially with nepa. It is always good once a while to charge with nepa or gen. The voltage is constant. If you can't fix the inverter get an external charger.

gadgetplanetng:
I always thought solar charging was better for batteries (especially LA) and Charge controllers ensure a constant voltage to the battery

Let's assume you
1. Plan to charge with grid and solar - your inverter will charge your battery at bulk/absorption but at float it won't make sense to charge with it being a pre-program parameters

Seek for an inverter with editable parameters or continue to use your inverter but never use grid to charge since you don't plan to monitor

2. Assuming your charge controller is editable, your panels is enough to charge your batteries without loads

3. Since your loads is unknown in your quote, it is safe to assume it abides by 50% DoD of your LA Batteries else you might undersize for the lithium battery too

4. LiFePO4 is a safer chemistry over Li-ion so there is little to zero chance of explosion while charging

5.if yoir battery is built with a good BMS then you only need to install and forget while focusing on productive activities

kaziem:


I am actually considering LiFePo4 of 24v 200Ah or 5kw capacity so I feel I am not undersizing.

Now talking about LiFePO4 with good BMS, this is why I need advice on good brands.

samnaija:


Controllers cant guaranty constant voltage, cloud effects , bad wheather and so on. You can carry out a little experiment charge with nepa only and discharge, also charge with controller and discharge. You will notice a difference in run time. The rule is once a while charge with nepa

GeorgeD1:


bro, you might want to check the veracity of your statement again. what the cc can't guarantee you is max
current output for a given voltage range all through the day. it can certainly guarantee you steady/constant
voltage for the greater part of the day while the sun is up except for an exceptionally cloudy/rainy day.
also, its not a rule of thumb to charge your battery bank with public power or nepa/phcn. some of us here
have been off-grid for years now, only using the sun to charge our banks and our systems are doing
extremely well. it depends on the size of your solar array and cc quality among other factors.

olopan:
Then you need to upgrade your panels to produce more power; attached is power production of a typical tier 2 panel

I don't know much about the batteries you listed but I am sure many others who use it can give a better insight

gadgetplanetng:

2nd thing, is the 180ah really 180ah?

GeorgeD1:


sorry for your loss bro. unfortunately not everyone who comes to post here is really a solar enthusiast.
most are here just to make profit and that's it. they are not necessarily grounded in the products they're selling.
going forward, any seller who just comes to dump adverts on the thread and vanishes into thin air should be
avoided at all cost. they don't weigh in on discussions. they don't offer any suggestions on problem solving.
they are just business focused. chances are that they don't know much about what they are selling and will be
very unlikely to help you sort out your issues if you call them up on any product purchased from them.
a word is enough for the wise...

samnaija:
Did you research and ask for the correct battery capacity or you just trusted the seller . Alaba boys will just collect your money and give you anything.

This is the kind of things I don't like, both the buyer and the seller do not know the product the have. This solar lamp is very straightforward read and research before you buy. Most in the market cannot do 24 hrs continous light. That is why it is written on the remote to choose 2 or 3 hrs.

mctfopt:



I've had Chinese living in far away China honour the warranty they gave. One even honoured it after 18 months in a 2 year warranty that I thought was one year

Most people in Nigeria find it extremely difficult to honour warranty. It becomes extremely difficult to truly believe their warranty claims as they mostly will not hold their end of the bargain when things goes south.

I understand some solar product marketers may not know much about the product they are selling, but that does not in any way exempt them from giving a warranty claim and reneging on the same promise; that's fraudulent.

@All

I have about 10 units of 250 - 260W Felicity/My Home Solar Panels for sale. They are all in good working condition. I just upgraded my solar panels.

Each one is for N26k each.

If you are interested, kindly contact me on zero eight zero three............. .

NB: The buyer will be responsible for the transportation to its final destination.

Current Location of the Panels = Wumba, Apo, Abuja

Thank you.

Is the buyer not supposed to trust the word of a Seller, about what the seller is selling?
"If" the Seller says there is One Year Warranty, is it the buyer that should say that is a lie or l dont trust what you are saying?

smallsmall:

The reason l am asking is that l always trust what a Seller on this FTA thread says abotu what they are selling, as l often think we are here to help one another, with knowledge and business sales.

smallsmall:

I wont be happy if we are turning this thread to "Alaba Boys will just eat your money", or is everyone trading from Alaba now a Crook?

2 or 3hrs of operation?

samnaija:


On my remote it is written 2 to 6 hour if u set it. but if you leave it on induction , it will come on at sun down, 6.50pm and by 2am it is off battery dead . So what I do, is on some then by 11pm switch it off then on others to morning. Most don't don't last 12hrs at a stretch at least my own and my neighbor. But because of my experience in solar I don't let them get depleted like my neighbor, that is why Mine is working while all is own has packed up

gadgetplanetng:
Your lamp isn't good quality.

The one at my home was installed August 2017, comes on around 7pm and I still see it on by 5am.
