I seconded you on this.. Na try i say make i also try sako ooo.. 😔

As from now on, any customer way want low budget, go they enter market hin self..

jonescosmos:
Na me pay ooo. my brother I hope you read the part where I said the setup didn't last upto 48 hours. Which Client go wan listen to your excuses and troubleshooting in such instance? I jejely respected myself and bought another Inverter and Battery and installed for them ooo.
It's a painful reality ooo. That's why some products are so popular while some will never make it past Alaba market. I am someone who never installs anything lower than Growatt and Felicity for clients. After hearing lots of noises about SRNE, SAKO, SMS, etc etc, I decided to try out the SAKO due to client's low budget.
See how the whole thing ended up. This Installation almost messed up my Xmas ooo. Anyway sha, Lesson learned in hard way.

Any client that wants a low budget installation henceforth go buy the devices themselves, my own na to install am for am with plenty of caveats.

Chief abeg send me that repair center address abeg 🙏 🙏 🙏..

Bb007:
We recently installed a Sako 4.2kw inverter about 3 months ago, and the inverter malfunctioned two weeks ago when we tried using a 1700W air fryer (every other appliance was turned off before turning on the air fryer). The inverter was repaired at their repair center and stop working today again. Seeing similar complaints from others raises questions about the quality of their product. Do your due diligence before buying.

Seh this active balancer na plug and play? See we way no Sabi build, no Sabi all this things oo.. The batteries way i they buy, them done they already add them inside. No until i jam this sako product.. My brother i done taya..

dollarnaira:
Baba do low budget stand alones.
PowMr cc 100k
100ah 240k
Satchet inverter 3kva 100k
Active Balancer 10k
400w × 2 = 220k
Cable

But most guys want beautiful boxes.
The above is a mini killer, ugly but working.

So one must use hybrid before person join inverter train? There are other options bro.

I kuku know jare baba mii
. But as things stand now, hybrid is cheaper than getting stand along wit same configuration.

It is a 4.2kw not 3kw. Our other 3.5kw inverter powers our air fryer. The brand has a quality issue. Plus an air fryer is not an inductive load

Obnoxious2001:
The inverter sizing is low na...

1700w air dryer is an inductive load.

Check am na


Most hybrid inverter are not Good with inductive load.

A 3kw might just output only 2.5kva of power...

So the whole kW might just be the PV power input of this inverters

We took it to their office at Alaba, they sent it to the repair centre at Festac theirselves. You can take yours back to their office

When we tell them to leave hybrid inverters alone, dem no go hear. Even some of them gan sef are over-rated. That 3KVA fit be 2KVA wey no even strong.
Let them keep on enRiching marketers and dealers

Leave hybrid inverters alone? No. Leave shitty brands alone.

3.3KW inverter. If you want, I go load am reach the 3.3KW sef to show you say e fit chest am.

Cc + 3ka Satchet inverter = 200k max
How much is hybrid of same capacity pls?

SRNE, sir. Bought for a bit under 400k back in April last year.

Note that the 3kva sarchet inverter is just a continuous 1.5kw inverter.

Avoid lithium bawo!!!
Not after using for 3 and half years.

You don't just get the point Sir.
Not saying don't use Lithium, or that Lithium is bad.

my point is to be sure of the dealer, brand, and that you can afford it.

There are people who can't easily afford a battery. in fact when their battery goes bad, they need wait till they are able to sell it off, before adding money to buy another.
Such people got no business with Lithium battery becauuse they easily would be swayed by cheaper / lower price points. Same with those who wanna make some money from sale of their USEd bad batteries.

Also to best of my knowledge, it's much easier buying FAKE or sub-standard Lithium battery , than a regular deep cycle battery.

Every thing has got it's place.

Same way, there are situations best suited for SSD disks; despite how good they are, not adviceAble to use for long data storage (archival purposes).

Thanks to the likes of Luminous and a few others, at least person fit enter their showRoom buy and be sure to some extent.

what I would suggest is, those of una wey dey jump around different brands, should help us share brands (even from China) that are capable enough and rate them in percentage.

Me as i dey, I get like 3 categories of brands I use and I rate them on 3 categories of Low Budget, Average budget and High Budget.

All these una SAKO and the rest, I rarely fall for them as I stick to what works, and I take my time to come to conclusion(s).

When I meet any client who wants to purchase things themselves, me no dey argue, I just give them cost of installation and that's it.

Anything you buy, I go install am for you. All I go do na to tell you what capacity and requirements you need.

if you ask of brand, I tell you, but most times, they wouldn't buy the recommended brand, mostly because they found others much cheaper.

It's sad that a relatively new brand is already misbehaving. To make matters worse, their distributors can be unnecessarily hostile to return/replacement.

jonescosmos:
Bro, toss this battery ASAP,

I had exactly the same issue with the same model of battery and SAKO 3kw 24V Inverter alongside 8pcs of 450W Jinko Panels, at nights the battery discharges like it's in a competition, The SAKO Inverter and Battery both refused to obey cut-off points and as such the battery discharges beyond DOD, I thought when day breaks and the sun comes up, the inverter will wake the battery up, but it didn't, client used GEN and NEPA to try to charge the battery, yet no power.

This horrible experience went on for days until I replaced the Inverter and Battery with Felicity IVEM 3KW and 5KWh Felicity Lithium Battery.
Now everything is up and running and the SAKO Battery and Inverter are both laying fallow in my garage.

Regrettably several other people have reported similar issues with SAKO products.

PLEASE STAY AWAY FROM THESE 2 MODELS OF SAKO BATTERY & INVERTER

47 degree celcius ??

Bro, why is the room that hot?

BigDickProblems:

Bro, why is the room that hot?

Room itself isn't hot, quite chill on the contrary.

My battery's in the same lobby rn and at 31°C. Inverters just run quite warm, it's at 44°C even with less than 300w of load.

The cells are not of the best qualities and they also have varying internal resistance

Haykay2001:
This 1 to 4..

I discussed this with you some months back.
I think this problem is common with 3kva HF inverter with 30-400vdc input and not just Sako.
For me, earthing was only able to minimise the effect.

Dam5reey1:
The Earthing thing was my conclusion.

but since my last comment about MPPT efficiency, I got some responses that assumed i was making things up, hence I didn't respond to the interference issue.

This plague applies to those 30V - 400V MPPT as it only happens when the Solar input is on.

No Earthing you are good 😊, But.....

No, I do not have a contact of an engineer that deals with solar system or solar station yet. We discussed this lightning thing here:

https://www.nairaland.com/7913296/bought-powerbank-1.2-million-naira/14

Albeit, the person was talking about Bluetti. As for Ecoflow, someone returned his bricked system to Lagos. As for whether they have in Nigeria, I can't say because the ones in Nigeria seem lazy based on the comment by gsparks01 here:

https://www.nairaland.com/7913296/bought-powerbank-1.2-million-naira/21

They may be also be dismissive of you. You may need to get South African assistance, etc. Or file a warranty claim, etc.

CC. gsparks01 Any help, Babatundehy, Hydronium ?

Power station or DIY solar system. Next time, as the rainy season comes close, run your system through a breaker to protect your investment, and if you don't have the money now, please check your weather app to know the kind of weather that is coming so you can manually unplug your stuff (especially for power stations).

from his post, it seems he has already filed a warranty claim and they sent him a new one.

Ferdiwar:

Yes bro

ManAdii:
These Sako issues I have read here was why I was hell bent on buying a TBB inverter again I wanted to upgrade my inverter to 3kw.

Even though I saw cheaper options which was half the price of the one I finally got.

I used their 1.2kva for 2 years without any problems. I resold it and the buyer is still using it until now.

I used the 1.2kva to power my home appliances including my refrigerator.

Any product that can give 5 years of warranty is no joke.

The cworth battery I got I just hope it won't disappoint since it's still a relatively new brand in the market.

Care to share the cost of these TBB inverters?

Hello Boss,

Do you use this inverter to power your AC overnight?

Exactly why I didn't quote any brand name, those variants ehn. 120V - 450V seems to be best option.

temi4fash:

My battery is on the smaller size (4.4kwh) so no.

Smaller indeed.

Active balancer is not a plug and play.

You'll have to do the connection of the lead wires to the cells.

Sadly the 4.2kw is a name plate and not the actual capacity of the inverter.

2ndly the Sako is on the lower tier and can't be expected to perform at par with the higher tier, so when doing a low budget installations try to oversize the inverter (eg. Use a 5kw for a 3kw setup).

Bb007:

Well let's say that lithium is fairly new to some people and our engineers are more of generic process rather than actually trying to understand the process and that.

Irrespective of the brand or technology one must definitely experience issues. When I joined this page lead acid battery was the trend and I can remember the series of issues people had then and the recommendations, and suggestions of which the main topic then was charging profiles including equalization and all that.

How many installers (engineers) knows how to properly set the charging profiles for the respective inverters and lithium batteries they install?. This is one of the major reason for most of the issues that arises from these installations.

Obnoxious2001:
So technically on this thread since the past 2yrs, we have actually had more complaint on lithium batteries than on lead.

Most lead complaint has always been issue around charging and tubular is taking the lead in that category, obviously poor design and consideration are the causes.

For lithium battery e choke, a lot of SNR men done pass through the needle eyes in the hands of this battery.
