Unfortunately this one doesn't. Had to connect to battery terminal and turn it on just to show u.

I have checked d manual both online and offline but no secret menu

It's not from the screen.
Check around the body.
There should be physical buttons or something around the body to choose battery type. Check well.
But even if you don't find, you don't need to worry. Just get a charge controller that you can edit. You've explained that you'll never run the battery even half way, so no wahala

Valto:
so how will he set low voltage disconnect on a dumb inverter

In his use case he has no need for smart inverter. He's good and better off with his 5kva inverter because he ont uses it at night and with his load, there's no way he'll ever get near low voltage. All he needs is a charge controller.

I've been using your lithium in a place for clocking 2 years with an old inverter and an external cc handles changing. From night to morning we never get even to 70% soc by morning.
If in worse scenario it happens that it gets low, the BMS has been set to cut off battery and, of course inverter, at a safe specific voltage.

You don't need a new smart inverter. All you need is anything reliable that can invert pure sine wave for you and you can work with LFP. That's if you know what you doing.

Oh please, get off your high horses and find something else to do. Do you know how many live matches we have seen in real life where they did not send notification before stripping themselves in the bool fight

I like Catholicism for their discipline and orderly behavior but one of the things I find ridiculous is man confessing to another man of his sins when you can talk directly to your maker. Talking to people is therapy sometimes so I can see the benefit in talking about the sins and taking the burden off your chest but we all know why you can't confess some sins to 'father'.

Guess Jesus was ridiculous in granting his sinful apostles power to forgive sin or even power to retain sins. That's the same tradition the Catholic church has kept since Christ being the first and oldest church. The origin of it is Jesus himself. If you call it nonsense, you call Christ nonsense.

And yes, you can confess any sin on earth to a priest even if you kpai the dad of the priest you are confessing to.

And for that pic you posted, the UK can make their laws, but no priest will obey it coz no priest can ever reveal what he hears in confession even if he has to go to jail for it.

How can I set it to charge and float at 3.45v-3.48v?
It's an sms (sunmate) 4.2kva inverter.

Check the manual sir.
If you press and hold the last button by your right you'll enter settings menu. Use the manual to guide you for each menu. Don't temper with that area if you don't know what you are doing.

For the figures i gave you, just times them by 8 if its a 24v system and by 16 if its a 48v system

Monsieuryankee:
Sorry it's an oversight

The load is just 250-300w

Then... Always make sure your charging voltage and float voltage are same. If not, some inverters will push all loads to battery even in sunlight until it gets to that default low float voltage in the inverter. By the time evening arrives, you have a lesser reserve to hold at night.
LFP doesn't like high float voltage, that is staying in one high voltage for long all day.
So i advice to charge and float at 3.45v-3.48v.
You must not follow this. Just my personal preference.

An 8kwh battery will hold 300w all night ( 300w x 16 hours = 4.6kwh).

If you are the installer, dedicate a day to be there and see how many amps are charging it till it gets filled up. Then watch how it's discharging and how many amps are leaving.
Its quite easy to diagnose such problem when you are there. Maybe neighbour de tap light 🤣🤣🤣.
You check each cells too (only if battery let's you see) to see if a bad cell is there. If one cell gets to 3.50v it may read as full when other cells are still at 3.2v 🙆🏾‍♂️🙆🏾‍♂️ chineke.

Its quite easy to diagnose sha when you are there.

Monsieuryankee:
Please you guys should help me

I installed
Sms (sunmate) 4.2kw inverter
Haisic 8kw lithium battery
600w jinko panel × 5 in series
Problem now is that, the inverter charges the battery very fast even when the weather is very dull, and it discharges very fast.

It can charge to 100% is less than an hour an hour and it discharges so fast.

I installed this setup with 400w x 6 elsewhere and experienced the same problem. Initially I thought it was the low voltage panel that was causing it.

But I'm still facing the same problem with this new installation in a different place entirely.
What could be the problem?

You didn't tell us their load.

Even a 100kwh battery will discharge to the end in an hour if you feed it a load of 100kwh.

bassdow:
shey you observe say na aJeBo (Hybrid) inverter e dey use. I no talk say e no go carry am; na make e no stress the thing. As for the brand, what do I even know

As pros it'll be cool we stop using HYBRID as a term here to refer to HIGH FREQUENCY inverters.
It confuses new people here who are learning about electricity and solar renewable energy.
It'll make people think that low frequency inverters can't be hybrid whereas many low frequency inverters are hybrid.

What makes an inverter hybrid is simply that it has ability to use multiple power sources together - PV, battery, grid and/or generator.

Hybrid features:

PV + Battery + Grid/Gen integration in one unit.

Bi-directional battery charging (charges battery from solar, grid, or gen).

Priority settings (e.g., solar → battery → grid, or grid → battery → solar).

Grid-tie + Off-grid operation in the same unit

Automatic source switching without interruption (UPS function).

All felicity IVPM inverters for example are low frequency hybrid inverters.

Jefferyzz:
Also 230v max voc?

Yes sir. Exactly same thing. Its plenty on aliexpress too with different names.

Because of rain and cloudy season see what a 10kwh panel can only produce all day. 😢😢

Who knows anything about this lithium battery and how to use the WiFi function? I can clearly see a WiFi antenna but can't figure out how it works

Jefferyzz:
There is this 60a mppt than can take up to 230v voc n are within 160-180k range. If u don't av the powmr 140a CC budget

Just found it's cousin in my friends house. It's a generic charge controller that different companies stamp their brand names on it.
Looks and feels subpar. I Will observe performance, though sun has been very absent coz of rains.

Bros abeg which one be africanus moskiterorum again naa?

Na him botanical name be that 😁😁

Is it just me or is latency exceedingly high today? Can Lagos folks confirm? I’m getting slaughtered in FC25. My latency is in the 90s.

Why you go dey use starlink play game in Lagos of all places even if starlink station dey near una?

You'll get better latency in Taraba compared to Lagos coz of una population

You are doing well Buffalo.

Now Americans know all of us here dey vex, including our animals.

FUN FACT:
African buffalos are responsible for most deaths by animals in Africa even more than huge wild cats.
They are only second to African mosquitoes (africanus moskiterorum) that take the first spot unaliving multiple thousands every year.

We've reached a level where government can do us anything and we will just keep quiet.
We no get energy go complain again.
If them like carry fuel to 4000, we don tire

Still very very much available for anyone that is interested.

Ha, wouldn't it have been cheaper for you to enter Sokoto town and do the return. Even if you spend 20k to get to town, you wouldn't have had to pay 144k

You won't understand the context. But the particular context i was in that particular time they sent the message, it'll take me a long journey to get to town, and will cost me approximately 180k for that journey to and fro, minus the stress and what it'll cost me at work. Doing my calculations, paying 144k was a far better option. As in by farrrr.

Jefferyzz:
It's not by display u go take no if controller nah mppt or not, open up d control n see d internals, or look through the vents, avnt see pwm come with rs485 port. The controller get app if u won see colorful designs.

That's cool. Nice one

Finally bought SRNE ML4860 mppt charge controller. Bought it used 60,000 naira + 10,000 naira (transportation).
Hopefully, it matches my taste else I would sell it.

As per the load being only 20amps, I can't use a charge controller without using that load port Ooo.

I built a couple of things that 70% of my loads don't use your regular inverter.

My Core i7, Core i5, and a couple of other PCs all run directly off 12-volts.
Even my 39-inch LED Tv-Monitor, and the 24-inches LCD monitor, all run directly from 12-volts.
Tv Antenna (the rotating type) runs off a USB port (5-volts). I just comot the transformer wey dey inside, attach USB cable to it and voila, e work.
Routers and Modems all run on 12-volts.

All my Fans are the regular DC fans I bought used from Arena Oshodi + a few I bought from Aboki Condemn which I fix and repurposed to permanently run off 12-volts.

Then I got a couple of high powered Desktop PCs I built; those need more than 12-volts but less than 20-volts due to the nature of work they do.

So you see, a lot of my appliances need direct 12-volts and to keep costs low, while supplying clean power devoid of noise, I use that port + should power run low (less likely but possible), it auto shuts down and wouldn't drain the battery bank enough to cause damage.

For all the charge controllers I got, I use all those ports, (including the USB ports for those that's got it); those that could cause an issue (due to high current draw), I built a circuit for them to ensure the power is clean enough. I try not to use inverters as much as possible. Na only chest freezers and occasionally pumping machine need inverter and those got their own separate installation

You find way manage the 240w limit wey the charge controller go give you be that.

Ournolly:
Interesting part of the question.
Did they replace it with version 2 or 3 router?

They gave me version 2.
I was surprised they had that

bassdow:
Abeh make una helep me drop reviews (both negative and Negative) on this brand

SRNE ML4860 60amps MPPT controller.

Intends adding it to my collection.

Its solid. As solid as its felicity cc compatriot.
Only that it supports only 20a for the load output. But that should worry you only if you are trying to connect DC load to it which i guess you won't. You are properly just using it to charge your battery and your inverter is handling AC loads.

You can also trust Growatt charge controllers. I've only seen their 120a sha over 400k.

Felicity, Growatt and this are great choices for external charge controllers.

bassdow:
Hybrids are more efficient but very fragile and even that efficiency is almost equal to the non-Hybrid (transformer based) ones nowadays. The gap used to be wide back in the day .

I often see many here thinking that hybrid means transformerless while non-hybrid means transformer based. That's wrong.

Hybrid only means it does not do only inverting. It also has an extra function, in this case, a charge controller that can accept your pv arrays.

Transformer based are just low frequency inverters while non-transformer are high frequency inverters.

Many transformer based inverters today are hybrids. And they are the most solid in holding heavy inductive loads over high frequency inverters.
You are absolutely right that many can't repair these low frequency inverters. They are the new development in the solar inverting world today, but they have their big disadvantages too which i believe further scientific developments are improving and making better. The fact still remains that they are still fragile as you said compared to versions they are trying to improve on.

bassdow:
but the fact a sticker or painting reads MPPT, doesn't necessarily mean it's a half decent one

Once i see that kind of display layout, even if they type the MPPT in capital pro max letters, i doubt it and run. They are just glorified pwm. I tell people a lot to change them to something better. Even felicity has one of the most solid real MPPTs.

I'm a person that love to use external CC if though i use hybrid inverters. It's for a personal reason many may not agree with. So i always want them to be solid and effective.

Just by the weight, you'll know a 17kwh LFP pack from Valto / valtech contain real high capacity cells.
Forget all these fraud brands that give you 20kwh but it's either only 12-14kwh or grade F cells. I won't mention them but you know them all. You've them in your homes and offices.

Go for these Nigerian assembled batteries.
As long as you are sure the cells are original grade A, the internal wirings are appropriate, the cells have some compression, and the BMS is active balancer (which many big brands don't even have), then go for it. Above all they are cheaper and more market friendly.

God bless Valto and Mrreed plus others doing it in this house.
You all are lighting our Nigerian homes, making sure everyone can afford long lasting solar battery solutions and doing the Lord's work.

One day i go buy motor for una 😁😁😁

brightk:
always plug it to a surge protector... starlink is not different from any other electronics

I had a surge protector when generator boiled by starlink router immediately.
I no know which kain surge protector i go buy for 6k then

georgee:
Power surge issue

Open a ticket from your account profile and explain what happened with pictures of damaged areas of the router or cable

It will be replaced free of charge

Dunno whether it will be replaced with a Gen 2 or 3

I didn't enjoy the free of charge.
They sent me free router and a DHL paperwork to return the spoilt one in 4 days.
Living in sokoto bush where i couldn't do that, they charged me 144k after the four days limit passed.

Challspace:
Older version, Gen 2

Could be the router. It's it showing light under?

FORWARDEVERLY:
Sias by a confused catholic church that has priest that molest little boys both in Nigeria and in Rome...
Eghú iberibe 🙏💯

Individual sins are different from institutionalised sin 😁😁😁.

The Catholic church has never told any person to molest children. People do it coz they are sinful.
Compare that with an institution as the anglican church where they refuse the teachings of Christ and allowed to cancel marriages at will... Where they ordain women which Christ never did... Where they approve homosaxuality as not sinful (approved by the institution oh and not just personal sin) and even let geys and lasbians to become clergy.

So... Type again what you said lemme see.

In the Catholic church there are members who are thieves, geys, criminals etc like in every place. But the difference is that the Catholic institution disapproves of all these immoralities whereas others accept them

Challspace:
My Starlink has decided not to power on today 🥲

Old or new version

The Anglican church is literally a church that left the Catholic church coz their leader wanted to marry a second wife that is forbidden by the church.
The entire church is built on immortality and falsehood. Why do you suddenly expect the church to survive in righteousness? It'll only grow in the immorality it was built on

Chai...

Someone above posted his charity in different zones and called some of donations insignificant.

Omo, and na poor man oh. Person wey never donate anything to his own village dey turn referee on another man's wealth and use of it for charity. God abeg oh.

CuteMaro:
Good observation Chief. The wire in use is a 16mm. The highest I have pulled is about 45amps from using a 1.5hp A.C, my pumping machine is 0.5hp. I set my charging speed to 40amps max.

I don't plan to use my AC with this set up anyways. Just for lights, Tv and Freezer and other light loads.

It's cool then with 16mm. Weldone boss
