Hello solar gurus in the house. I've been a silent follower of this thread. I recently have a concern about the poor performance of kung long batteries in an installation in less than 6 months, I want to know if anyone has a similar experience with the brand.

The installation has 4 pcs of battery connected in a 48v setup.

The inverter used is ipower plus 5kva MKS axpert inverter.

The system has 3000w of solar installed (200w ×15) connected in 3×5 set up.

Average load on the system is 650w

Battery backup for night time use was up to 6hrs initially, but now barely last up to two hours.

I've tested the batteries, they seem OK, (just low on charge).

But after charging for approximately 15hours, same issues noticed.

Has anyone had similar experience with this brand or any brand??

What can be done to salvage the situation??

PS: there is no stabilizer used in the set up, cos power supply is fairly stable.

Any/all contributions and suggestions will be highly appreciated

Nice moves...meanwhile, still thinking why Mercedes Benz C300 is the official car for yahoo boiz??

Nice post... Following

Thanks very much on this. The vin report is clean. There was only a dent to the rear end when bought as salvage from USA. I just want to know the general availability of spare parts for this model. Can other Lexus car parts fix in...(eg the ES3XX model),

CarGuideNG:
It may be a Nigerian used vehicle, but a Vehicle History Report would be a great idea to ensure you avoid vehicles with prior potentially expensive damage such as flood/water damage. You could also verify the genuine mileage.

I'm at the verge of paying for a Nigerian used 2008 Lexus GS350 with low mileage. I want to get expert opinion on this vehicle. Things as simple as availability of spare parts, any major or minor problems with this model would be highly appreciated.

What is the issue with the vehicle, how is the transmission?? Any issues, let me know.

580k, let me know if can fly.

Hello everyone, and compliment of the season.

I want to know if bill for clearing vehicle at the Nigerian port is the same for both salvaged and clean title vehicle??

If different,

Please, how much will clear

2007 Lexus GS 350 (salvage)

2007 BMW 328i (salvage)

2005 Lexus ES 330 (salvage)

Vehicle will be RORO via Grimaldi from USA to Lagos.

I would appreciate comprehensive details, and any other thing I might need to know.


Thanks in anticipation

I'll pay 80k if it comes with other accessories

Why are our state government so myopic?? Cross River now producing toothpick, Akwa Ibom state also producing toothpick. What happened to other industries, textile, ceramic, glass, food processing/preservation??

How many people can that toothpick factory employ??

So, is buhari the cause of this one too??

its nice to hear that the brand can be trusted.

please do post a price list of their inverters if you have?

zeestone99:
Oga big Rover (mark Zuckerberg of R.E ) gud to see u can testify that Felicity honor their warranty claims and have a strong presence here in Nigeria... Do I need to say their products are very affordable.

Hello kakakibuy, how much is the total landing cost of a BMW E90 (318xi or i) version with low mileage.

Prompt response would be appreciated.

Can you make the sound bar/sub woffer more visible??

I might be interested

My Nokia 7+ is running strong....don't need this fake as* phone

Very interesting read....

I'll like to see what the religious community have to say about it.

This is not an accident...



This is a sign.

You can visit fieldlines(dot)com and thebackshed(dot)com they have done several modifications to the egs board
for me I still code the ATMEGA series MCU

Thanks boss....

Much appreciated

Hi. Please at what battery voltage is your 10kva inverter? This MOSFET mentioned is 80v VDS max.
I'm also into construction of digital pure sine wave inverters. The inverter board beside your blue casing looks familiar. I think it is based on ECG ?

The battery voltage is 48v.
Of course it's pure sine wave.

The board you saw is based on egs002.
I got it to see if I can learn a thing or two from it to add to my design.... So far so good.

This is the type of high power mosfet used (HY4008), you can check up the datasheet.

DUNKA:
what is the price?

This 10kva will go for 520k.

NiyiOmoIyunade:
This looks good bros.

Please tell us about the internals of the inverter - that is what we need to see/know. Your design philosphy, nominal system voltage, safety features & protections e.t.c.....

efuro:
.

God bless the work thy hands. It's good to have geniue local content in RE. Am proud of you already.

By the way, what will be the standby/idle consumption of this 8kw, I assume it will be transformer based inverter.

finally, I hope it will be affordable. I recall my early attempt to commmission a engineer in a solar related federal agency to build 150w panel for me. I was billed N900/watt, I had to cancel my order, and got indian Tata panel @70k for same wattage. Nowadays panels are cheaper than phones.

Thanks very much for the encouragement sirs. And a big amen to your prayers @efuro.

I'll do a proper analysis video on it soon. But I can tell you it has all the protections imaginable and standby consumption is very low. This particular one is a 48v low frequency inverter. I use high power mosfets for my designs (some people call it igbt). It runs like a beast. It is very affordable and I give 2yrs warranty on it.

Please, enough of this name calling..... Let's move this thread forward. We have a lot of great minds here. Nobody should drag us to the mud.
Let's do what needs be done and settle any grievances we might have.



I'm currently designing a 10kva inverter for a client.

I think you all should look at it. I'll post more details about it later.

Everyone is free to commend or criticize.

Here to read comments

What's the location for inspection??

Any issues with transmission??

If no,

Will you offer a written Warranty on the transmission ??

This guy could be empowered to manufacture military grade combat rifles. Such talent shouldn't be watered down. But monitored by security operatives to make sure that all weapons manufactured are accounted for.

Same goes for our brothers locally refining petroleum products.

tiredoflife:
The word of God says go into the world and preach this gospel
Whosoever believe and is baptized
Key word believe and baptized

So did she believe
And if she believed
Did she get baptized

So yes that guy is right
She is on a highway to hell

How about babies that get to die before getting baptized.... They are definitely going to "hell" right??
