please where did you get the box from and how much did it cost excluding the cells

Got the box for $170 excluding BMS and display.

Alibaba of course.

Ferdiwar:
This is nice weldone

I have the black version.

Welcome to the club

maklelemakukula:
Did you use Eve grade A cells

Judging by the cost, it's not grade A, though they say it is. Who am I to argue? Lol

omotoda:
Feed our eyes now,let's appreciate the Lord's doing

Here goes nothing. Lol

Can we go back to sharing tips?

I'm tired after assembling my 14.3kwh pack. Came in here to check what gives and all I see is back and forth about who sells the cheapest.

I'm here for DIY tips only and any other thing related to RE. That's all.

Anyways my 14.3kwh battery pack looks good

It's good to do it yourself. Lol

Nteogwuija:
Okay, thanks. Ordering it right away.

Someone sells this in this forum. Unless you like Jumia because of convenience/shipping.

maklelemakukula:
I saw several videos about felicity batteries that suggested this and that's why im leaning towards growatt
Are valto's cells grade A ?

Grade A batteries are expensive. If anyone makes batteries with grade A for DIY, must Nigerians won't buy it. Best to get a good cell with right capacity.

Good evening experts,
Please which inverter would be best for my home usage out of Schneider SW4024 & SW4048? Also, what's they minimum capacity of LiPo4 battery bank that would be required?

I have a 4048, will advise you to get that instead of the 24 version (4024) simply because it's easier to run high capacity lithium battery in 48v instead of 24v. Both are same capacity though just different battery system voltage.

Also you get to run higher number of solar panels in 48 configuration rather than 24v with same solar charge controller.

There is no "minimum number" in battery configuration. You buy battery according to your load needs. You can get a 500wh lithium battery in both 24v and 48v. Same inverter can also work with a 60000wh or 60kwh battery.

Using generator analogy, your inverter is the generator, your battery is the petrol. The amount of fuel you buy is dependent on how long you plan to use the generator. This is applicable to inverter too, size of battery depends on the load to be powered and the duration you want it powered.

waleayeni1:
Please is there any reason why no one is looking at my question? If i offend make una forgive. Please help.

Here is a DIY thread, users here often reply to posts they have experience in or interested in. No one will deliberately ignore a post made by a user. Also no one here is paid to reply messages so reply may be slow. Cheers.

Good morning, please does anyone know what the configuration for growatt hope 5.5l-a1 on growatt spf 6000es? I keep getting error 04 and 20.

Go to setting 5 and set PTCL to L01 036 make sure cable is on BMS and 485 PORT on the battery.

KA24DETT:
POW-HVM11K-48V. It states 11,000watts maximum input. We had a PowMr 24v hybrid which took 2x over panelling so we figured we can push our luck with this inverter. It was $800 inverter, worse case scenario. we lose it
30 pieces of 550 watts solar panels wired 10s3p.
20 pieces of 550 watts solar panel connected to POW-48140A ( HF MPPT Controller).
Remenber, amps is pulled from panels. You can have as much panels you want but when the battery is full, the panels responds to the load requirement.

PowMr? Kindly share pictures of inverter

burnerr:
I got it for N605k from fouanistore.

Thanks a lot

Dam5reey1:
All Guess goes to Fouanistore, based on other parts

Thank you

burnerr:
Hi house, great work I've seen being done on this thread.
I'll be needing your help once again.
I finally got the growatt spf 6000es and the growatt .

If you don't mind, how much did you procure this 6000ES and where did you buy from?

GreaterFuture:
Seller said it's an actual petrol Generator

Pay. Update us on how it goes.

GreaterFuture:
How's this possible?
Generator for 13 USD.
Checked the as very well, it checks out for an actual Petrol electric Generator
Several of them there

They'll ship you a toy. Lol.

70% of Nigerian Renewable Energy installers/electrician's needs to be retrained. Someone today installed 2s 6p with solar panel of VoC 40v on an inverter with MPPT range of 120v to 500v and wondered why it was no longer charging batteries by 3:30pm.

His reason: system voltage of 24v requires 2s.

Ok.

NoonMasamune:
Had anone here returned a defective item back to AliExpress before? I need guidance on the process

I have, but if the item is not worth more than 50USD don't bother, seek for alternative way of settling the dispute. The reason is simple, returning things to China is freaking expensive. Also the item being returned may be lost in transit
I've returned a phone before when Nigeria's naira was still strong and economy is not in shambles.

Kaybthaniels:
Good morning bosses, my growatt inverter stopped charging my battery since last night even tho there is electricity, I am not very savvy with these things tbh and my installer’s number isn’t going through at the moment, Please what could be the problem?

I don't think the power is getting to the inverter. Notice the 0v that shows no voltage on the input. You might need to check on the input breaker to see if it has issues. Or contact installer to check why the inverter is not seeing input voltage.

Good morning my Gurus in the house
Please does anyone here experience a freezer not freezing with an inverter but always freezes when there is NEPA or Gen set is on. The freezer only gets cold despite being on for 6hrs to 7hrs. But with Nepa or Gen within 3hrs it will start freezing.
The Freezer is Thermacool. It is a 24v setup. 2.56kwh Cworth Battery, 3kva 24v SAKO inverter and 4pcs of 590w Jinko Solar panels connected in series. Thanks in anticipation

To troubleshoot further, you might want to:

Measure the voltage at the inverter terminals when attempting to start the freezer.

Check for any signs of wear or damage in your inverter and battery connections.

Test your freezer with another known good inverter, if available.

redgem:
Sometimes they just let it go because they really don't understand the terms used.... Using myself as an example....

We have good people here. If you don't understand, I'm sure many will provide further clarification. It's a DIY thread, also doing a lil research to understand terms won't hurt. Cheers.

jonescosmos:
Bros abeg help us do a video to test this your Energy Saving Device according to this drawing.

A common source NEPA/GEN connected to two Energy Meters 1&2, Your Energy Saving Device connects to Energy Meter 1.
Extension 1 is thereby connected to your Energy Saving Device.
Extension 2 is connected directly to Energy Meter 2.

During your video, you will have to plug the testing Load Appliance to Extension 1, show us the reading on Energy Meter 1 and then plug the testing Load Appliance to Extension 2 and also show us the reading on Energy Meter 2

Anything less than this illustration is not meant for this thread, because we will not believe it.

Even if you send him two energy metres for this he won't do this. He underestimated the audience in this thread, he must've thought here is Facebook where people believe a "fuelless generator" running only on a one 7ah battery powering a 32 inches monitor, based on a 5-second video clip, is capable of powering every household appliances (pressing iron, washing machine etc) simply because the person on the clip advertising it said so.

When the uneducated user ends up buying the "fuelless generator" and finds out it's just a 500VA PC UPS in disguise, he must've been blocked by the scam seller who must've sold it to him at a cost of 5x the cost of a regular PC UPS.

BigDickProblems:
I have not experienced it before. But if I were in your shoes, I will disconnect the wire that connects to all loads directly from the inverter (I.e if you can do it) and be sure there is no connection to it. If your inverter is still showing the 14% load or so, then there is a fault. If it is not, then there something in your wiring that is causing that, probably someone has tapped your light or something else, but an electrician can figure that out for you.

This is my thoughts too.

Ofejiro20:
My inverter has been functioning fine for the past 3 years and I've only took it out for repair only once till this recent ordeal.

I've a 5kva inverter system so it'll stay at 1% load whenever I do not have any appliance powered on the system but now, it'll just stay at 13% without any load powered on the inverter which is not the way it was before.

And when I switched on my TV and Inverter 1.5hp AC, the load rate will go up high as 25% to 28% and my inverter will be working making a very loud humming sound just like those NEPA transformer make when it has carried load. The sound is very noticeable as the inverter is working and any visitor can easily notice it which is not the way my inverter works before.

This humming sound is different from the sound of the inverter fan as the Inverter fans as working pretty fine as it'll pause for minutes and the fan will start to blow out heat from the inverter which it was designed for.


I'm confused as what could be the reason why my inverter is inducing load of up to 14% when there is no load powered on it and it'll be making that humming sound as if I had NEPA Transformer working on my house?

Disconnect output wires and see if this load (12-14%) is still there, if it is then inverter may have developed fault. If it magically disappeared, then you may be experiencing some short circuit (live wire touching neutral) or generally fault in the wiring. Check and get back to the house. Cheers.

The Future series comes in 6000ES Plus H future, with 4Kw + 4 KW PV
and 2 units of 5.5 kwh.

Who is selling these?

dollarnaira:
Very very true.
I prefer an active balancer instead.

Some BMS comes with one. I think 2A is okay. I use JK with 2A active balance current. Keeps my cells balanced.

dollarnaira:
Exactly my point wrong charging voltage not because there was no bms. Bms would have saved him though with the wrong charger.

You still need a BMS, he still uses this charger even now but with a BMs. Wrong charging voltage wasn't the issue here. You need a BMS to avoid cells going out of sync and getting overcharged.

Moral of all these stories is to use a BMS with every kind of charger.

But you can always do you. Your house your rules. Cheers

dollarnaira:
Sorry o but how on earth will one overcharge a battery with a right charger bms or no bms?

Cc cannot overcharge your battery with right setting.

For cells to go swollen due to overcharge must be an extreme negligence. Few minutes of overcharge does not translate to instant swollen/damage. Your friend must have been charging at higher amp and voltage over a long period of time.

This happened over many months, not just a single day of overcharging issue. He was using a rectifier to charge the batteries. I mentioned it in my original post. It's 280ah and I can't really say it's high current charging that was the issue, even though it was two combined rectifier to give 100A that he used during that period. Issue is had he used a BMS he won't be needing to replace these cells.

JJacko:
People bypass the bms discharge port on Ebike battery builds all the time.
So why not on Home setups with the Inverter already having LV protection? In fact, most people won't need more than 100a Bms - charge only- (If you bypass the bms discharge port and connect Inverter leads directly to Battery terminals)

This is how my neighbour lost 3 of his 280ah cells three years ago. He bought Daly BMS (300A) and was too lazy to connect it. Ended up overcharging his batteries with 3 cells swollen so bad he was afraid to use it. The charger he was using was a 48v 3000w Huawei rectifier. It was a tough lesson well learned

Always use a BMS. Or get ready to either rebuild a house or buy new cells or both. The choice is yours.

omotoda:
I will like to know from experienced people here just for learning purposes: what determines the LVD on Lithium batteries itself. Is it set by manufacturers or is dependent on the type of BMS used.I was just wandering why some LFP will cut off at 9.8v,some at 10v and some at 11v.

Depends on BMS in use. Some BMS allows you decide the cut off voltage (eg JK, JBD, Seplos etc) some come preset.

Attached is my JK BMS power off voltage but it'll enter cell under voltage protect at 2.6v, you can decide to change this value. Any time any of the cells reaches this voltage, it's power off from the BMS and I'm yet to even remotely reach here since using the battery

Dam5reey1:
All the information available to the inverter..

PV wattage, PV harvest overall, Load,
Battery SOC (that 6% is actually the battery percentage) we ran the Batteries down to 0%

Thank you.

Dam5reey1:
Wifi is for monitoring, and getting data, why do you want to shut it down?

Is the Purpose of having inverter is not for UPS?

Hi, what data can be monitored via this wifi?
