I don't think there is anything wrong in what he showed. Like he rightly said, maintaining good top and bottom balancing silmultaneously is quiet difficult. And by the time you are discharging your lithium battery below 3V, you are already looking for trouble.

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.

My brother, have been battling same issue in one of installations, I was dumbfounded listening to those problems u shared from my client cos i never had or seen such scenario before until I visited the site n saw things myself, what I discovered was that the sako inverter interference n d other problems u shared above are due to the fact that u connected the inverter to d earth... I contacted their support n the person said I should connect only the panels to the earth n when I further asked him that how do I protect the inverter from lightening through d grid, he responded that such is a natural disaster n can't be prevented ... stay away from Sako products n prioritise ur mental health

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.

Hi, is the PowMr 100ah now 240k?

.

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.

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

If there is interference from the inverter with electronic devices, the inverter is not pure sine wave.

Outside using an oscilloscope to affirm this, the humming sound at lightning points was not noticed and standing fan runs smoothly so I don't think u are right on this one boss

hayzhed:
An installer once told me that it better to use and external charge controller on an hybrid inverter with inbuilt charge controller. He claimed that it reduces the stress on the inverter. Please, how true is this claim?

There are several reasons why you should use an external charge controller.

1. You're aware of quality of what you using to some extent.

2. the charging system is properly sized.

3. should the hybrid inverter go bad, you still got the charge controller.

4. You don't risking killing your battery just because the hybrid wasn't properly recharging the batteries.

5. Hybrid inverters, consists of more mosfets and transistors, than an actual large enough transformer and those things heats up (reason they have heat sinks). Now depending on your battery capacity, the hybrid inverter could go though lots of stress to recharge the batteries.
Recall how laptop chargers get warm / hot while in operation - it's because such laptop chargers are lower rated for the laptop they're being used on.
Also the saying - don't put all your eggs in 1 basket is true here.

6. With dedicated charge controller, you have the luxury of deciding quality and capacity, but such don't exist when you use Hybrid inverters.

6. In Hybrid inverters (especially the low to average ones), the charging system is secondary and more of an after-Thought hence hardly performs like those specifically made for charging.
As yourself, those phones that are advertised as power-Bank, how well do they do performance-Wise in their main core areas such as network reception, quality, etc.


Most (potential) clients often go for Hybrid inverters, just to avoid the cost of charge controllers; little do they know they still end up paying (more)

Drgreatone:
Not true. Less said, the better.
Only reason to add an external charge controller is if you already used the maximum panels size ur system can take.

hmm

Dam5reey1:
For many Hybrid Inverter, The Controller inside Hybrid is a separate Board, just like the Charge controller, its in same box does not mean the inverter is the controller.

Laptop with inbuilt keyboard and mouse does not stress it. It just made it compact.

For many Hybrid Inverter !== For All Hybrid Inverter

Except that inBuilt PWM / MPPT charge controller component could be swapped out and upgraded when need be, or even used externally and alone, I still never recommend hybrid inverters.

TeleVision wey get inBuilt DvD player , can never have features and capabilities of a standAlone DVD player + should the Tv go bad beyond repair, the DVD equally goes with it.

Most times, One really can't even tell if it's PWM or MPPT

When I'm in market shopping, rarely do I consider those Warrantee and/ or Guarantee grammar wey dem dey talk. I regard things first like I'm buying from the street, then the grammar comes 3rd, not even 2nd.

All those warrantee and Guarantee are nothing but marketing; because when you need one, they turn to Insurance companies, looking for the slightest reason(s) not to honor their promise.

That's even one of the numerous reasons I often discourage people from using Lithium batteries. Except you're 100% sure of the dealer + brand, and not price-hunting, just leave Lithium alone.

Electronic appliances that would have such issue ain't Fans or things with motor. Na mostly appliances with sensitive components such as laptops, medical appliances, etc.
Things such as Fans, Heating appliances, etc would work well enough

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

Dam5reey1:
Lessons learnt boss, Can't even trust any seller again.
So much cutting corners here and there.

Lost trust to extent I decided to build LFP batteries myself, use my own BMS tested and trusted settings, which gave me more peace of mind.

Sheybi you for listen to me small. Except You sure of the brand and dealer, just avoid lithium.
Even the ones you think are wealthy enough, do same. Funny enough, despite all the corners they cut, they rarely retain the money they make

alosbaba007:
I wont advice you buy used panels, save up and buy brand new reputable GRADE A solar panels to avoid
headaches, its nt a must you bjy everything at once plan towards it and buy small small
Check Fouani, Gennex and Techland website to guide you.

unfortunately, not everyOne can afford brand new quality Solar panels.

my suggestion is, just to ensure you buying the correct capacity listed on the sticker. No go buy 200watts, thinking you got 500watts.

I can imagine how u felt. Unexpected expenses.
I may just be doing standalone inverter and charge controller for low cost setups to protect ny peace

Its not Hybrid debate, I have been using Hybrid since 2016, from Luminous with PWM till my current Hybrid, sold one off to a Nairalander at some point the person still uses till date.

Many like you said same with Manual vs automatic cars. Not sure people are interested in manual anymore when AI driven cars are currently being developed.

There is no Harm in using CRT TVs instead of Oled TVs because OLED do have screen burn issues abi no be so? Or is it not easier or cheaper to replace LED screens compared to OLED?

Enjoy your stand alone while it last!

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.
