Omo eh, this bread inverter just deu give me joy. I keep seeing issues everywhere and I've never turned off the inverter or checked my battery level even after 5 months of installation.


Just there doing it's thing and supplying constant electricity 24/7

God don butter your Bread

How do you guys calculate this power draw?

For instance charging my battery at 15 amps is pulling about 400w using generator.

Please educate me.

With a meter you can see power drawn - current, voltage and of course the power.

With a clamp meter you can check the inverter input current, if you measure the voltage the product of the two is the power.

Good day senior men

Please does anyone here know about this stabilizer? Can it power a 1hp submersible pump?

Thanks for your reply.

The maximum current draw of a typical 1HP submersible pump is between 6A to 6.5A that is around 1500W. So a correct 5000w AVR should be able to power that

I'm particularly interested in H*KVision and D?hua. I don't know if these camera names are keywords for banning

Try 1688

Please our lifepo4 battery builders where do you buy casing for your projects

You either construct one or buy from China.

FEGEITOK:
I second this.

Our generator repairers are notorious for altering the frequency of petrol generators because 1. The noise is too much and 2. Maybe they think it will use less fuel

You know how it goes.

Also given that most devices can still work with horrible frequencies people don't know that this may be an issue.

Hi. Thanks for your input. Fortunately this issue has been sorted.

I lowered charging current to 15 amps and that was the sweet spot.

Oh, I see. This was a capacity issue. Glad you've fixed the issue. Totally hate the use of generator ..but I understand people who do. I don't own one.

I own a 3.5kva Generator, my inverter is 24v 4.2kva. No matter what I do it won't charge from the generator. Even with charging current lowered to 20 amps.

Whenever I turn on I always hear a clicking sound from the inverter and the light will be flickering. My system is grid only for now. How do I go about this?

Your generator frequency may likely be the culprit. You may need to replace the AVR of your gen. Or adjust the speed to see if you can get between 48Hz to 51Hz.

Most petrol generator produces terrible frequencies of about 40Hz or something like 70Hz. These type of frequency are often not compatible to battery charging.

Good afternoon everyone, please has anyone here ever received a refund successfully to their bank account from AliExpress? If yes, how long did it take?

3 to 20 business days

dollarnaira:
1hp is not 745w in real life oo
0.5hp is doing 792w i.e 66A at 12v.

True, my 1HP AC power fluctuates between 250w to 1100w depending on set temperature, mode, or ambient temperature. But I notice it is an average of 400w most of the time. LG Dual Inverter did a wonderful energy saving AC here.

Not the one I ordered though
The problem is many of you don't take time to read reviews before shopping on Temu...

Stay blessed ✋

if you don't mind which make did you buy?

Major Upgrade to My Solar Setup (20kW Hybrid System)

I just wrapped up a big upgrade to my solar system. It’s now a 20kW hybrid solar setup — built mainly on traditional off-grid components, but I also added some grid-tie functionality using Deye Micro Inverters in AC-coupled mode.

This project has been in the works for over a year, and there’s a lot going on under the hood beyond just the specs:

IoT & Control: Built a custom system computer using a Raspberry Pi 4 Compute Module running Venus OS + Node-RED.

Smart Automation: Created several Node-RED flows to keep the system efficient. One cool one uses the Solcast weather forecast to predict tomorrow’s solar yield and automatically decide whether to allow grid input — and how much.

Monitoring & Dashboard: I switched to Grafana for visualization. The new dashboard gives a detailed view of performance and energy data.

I’m working on a detailed overview (with schematics) to explain how everything is connected. Hopefully, it will inspire anyone looking to build or upgrade their own setup.

You are doing well.

You've got some great RE system.

Please who knows about Powmr repair center in Nigeria? Please i need info on this, thanks.

I doubt they have any.
This is why most buy from dealers that can at least offer small warranty.

Good day everyone

I am using Powmr 4.2 hybrid and Haisic 25.6v black one, grid was on (charging was going on too), and supplying the house (load was lights and fridge), suddendly i heard a sound and power was off. Went where my setup was, saw inverter in error mode. Error 9 (bus soft start failed), battery shut down (battery is still shut down, not on)

Please what is the way foward? Location is Benin. Please

Please note my system is well protected With all necessary protection. It was not rainy, just normal grid usage (AC bypass mode) with less than 200w loads.

Inverter power board issue. Send to a repair center.

adrusa:
To illustrate the point about batteries connected in parallel.

4 batteries. Felicity 200AH with ANT BMS. Tactel 300AH with JK-BMS. CATL (DIY) 280AH with JK-BMS. Valto 173AH with JBD BMS. Felicity and Valto are fully charged, 100% SOC while Tactel and CATL are still actively charging. Each of the batteries are doing their separate thing based on their SOC.

Awesome. How did you have all this data nicely in one location?

Reports coming out suggest that the Afriland Towers Fire was started in the INVERTER ROOM.

"According to the Federal Fire Service team leader from Ebute Metta, Mr Ehimen Momoh, the fire started from an inverter battery in the basement and spread to a parked Toyota Sienna and a motorcycle, both of which were completely burnt. Other vehicles in the basement were, however, saved."

Its very important that if you are installing solar systems to get EXPERIENCED installers who calculate load, wiring sizes and use fuses, breakers properly. Ensure that you also install smoke detectors and a fire extinguisher nearby in case of fire.

I've personally seen a fire that started in an inverter room at a bank, and it turned out a faulty AC was the culprit. The AC caught fire, and melted rubber dripped onto batteries stacked below it, which were subsequently engulfed in flames. Without the CCTV video, many might have thought the inverter system was to blame.

​Anyway, nothing still beats using experienced installers or workers for your job. You can't cheap out on safety.

​Also, I wonder why our tall buildings in Nigeria don't have fire escapes. This is especially concerning since our Fire Service lacks the capacity to rescue people stuck in high-rises during fires.

​I just hope people install fire safety devices, like FM-200 fire extinguishers, in such sensitive areas

BangaRice:
The issue i discover about we buyers is assuming what favours us. Most cells arent grade A and they hint by including something like "<=5000 cycles" in the specs. Some are even rated less than 2000 cycles. It shows you that out of the total lifecycles, someone has used some of it thus the lesser than symbol.

Some chinkos also exploit the space created by such gaps in estimated life cycles of cells to sell not so good cells.

You can do all the due diligence in the world, as long as you not in China, you don't get to see what is shipped to you till you receive it.

But like I said, yet to take a loss from buying from China. Still the best place to do business.

favouredbymercy:
Come to think of it, has anyone come to the end of life of their lifepo4 battery?
LFP is baba

I'm looking at four cells of LFP at it's end of life, it's a SinoPoly 100ah cells I bought around 2018. I killed it sha as I was using it to start vehicle without BMS plus other crazy things

The only thing I miss in lead acid is the money I make from selling it as scrap at end of life

I don't miss any other thing.

LFP is king.

Dam5reey1:
Incomplete story!
How much did he buy the cells cause 100ah are not cheap! Share pictures if possible. Cause when we buy the Seller send Pictures and videos even before they ship! Or was it a case of they sent different battery from what they showed him?

They didn't share picture before shipping. But they shared picture before he paid.

Seller has agreed to a refund

My bro I've seen things in Chinese importation- but I've never taken a loss. Most of the time I don't just bother to share some experience here as I'm busy with life offline

dollarnaira:
This is bad and painful.
But can you really fight this out successfully?
Distance/cost of shipping alone is discouraging.

They are trying to make it good. Like reship some numbers of grade A. Discount on future purchase. This may be a mistake. At the moment my guy can't tell. Just wants some grade A battery to be shipped to him. He will try to sell this one as B and take a loss. Doing business no easy.

dollarnaira:
But the cost of each will say a lot.

If you show another battery and.ship another...we have a name for it- fraud

Chinese lithium battery market is crazy.

Loads of shady deals going on there.

If you have a good supplier hold am tight.

The rabbit hole is sure very deep.

My guy bought 250 pieces of 100AH supposedly new cells. Cells arrive and it's used cells with a new cell wrap. Supplier is saying they are not aware. Case still ongoing.

DIY is still king. Can't have it any other way.

hakinze00:
Thanks so much for the feedback but the goods I received was replica speaker and it sounds really awful hence the reason for return and aliexpress said the seller will cover the shipping expenses but nevertheless I will go to post office and speedaf office close to me and compare the shipping fee if it is too much than expected then I will decide if i should count my loses.

Note: I tried the refunds only options the seller was offering a mediocre compensation compared to the value of the item. The speaker cost over 500k and the seller was offering a compensation of just 11k.

Fake JBL speaker?

I fear to buy JBL, B&O or Bose from China.

You may be better off buying their premium product like Anker. Edifier, etc
