FEGEITOK:


It is for office use.

I hope it turns out to be a good purchase, if not it will be shut down.

I have to supply internet to several devices on 2 floors.

My key consideration was that although other providers may offer faster speeds they are not very clear on the data cap. How much data will be used before they throttle down the data or the speed or both

As you know there is not really anything like unlimited internet connection.

"Starlink will slow down speeds for Best Effort and Mobile plan customers. The bandwidth priority goes to Standard, Priority, and Mobile Priority users. " that is a quote from starlinkhardware dot com

As someone said on Reddit:

"Networks have a max bandwidth. If you can't (or won't) build your network so that peak < max, then that data gets spread out over time. Doing that in a controlled manner is better than letting it happen 'naturally'.

Most networks are far below their max most of the time."

I just want to test if my office will consume 1TB a month, and to guarantee that even if they hit 1TB per month the internet will not be cut off.

Airtel has a 1TB plan but it would cost me 100,000.00 and each time it is exhausted, I would need to shell out another 100,000.00

With this system, I can get the 1TB for less than half of 100,000.00.

I have MTN 5G and also plan to get the Airtel 5G and also have Glo 4G for home/mobile use.

You might want to put up some restrictions on your network.

In my office I used Mikrotik RB1100AHx4 to secure my Network. Using Layer7 Regexp and firewall to block so many things like Windows and Office Updates so they get it from the File Server, Blocking downloads by size and file types, Blocking bittorrents, Blocking Social Media and Streaming services (for some users), etc.
Used Adguard DNS for block explicit contents (porn), adverts, malwares, etc.
Used ARP=reply-only on your Local Network Interface to make sure that VPN and manual IP or DNS users can't use your network, except they use the IP and DNS that your Gateway allocates to them via DHCP, any attempt to alter or use a manual IP or VPN knocks them out of your Network, etc.
You can always have a list of IPs that are exempted from these restrictions though.

The pictures below can guide you further.

Properly set-up lithium pack will not have thermal runaway.
Thermal runaway is caused by either unmatched cell or wrong connection.

I've seen some videos telling us that 5kva 48v Felicity Hybrid Inverter (Ivem5048) consume less than 40w on idle mode.
I carried out the test on mine by shutting down everything in my house, leaving only the inverter on and my Victron BMV 712 recorded 72w.
I've also used clamp meter to take the amps reading of the cable and multiply with the voltage and I got the same 72w.
I've concluded that Felicity Ivem5048 consumed 72w on idle mode.

Again, I tested Felicity panel 350w few days ago at about 10:30am with multimeter and I got 297w which is about 85% of the stated capacity.
I'm sure it would produce more on a good sunny day.

What Is Thermal Runaway In Batteries?

Perhaps one of the most significant drawbacks of using batteries is that they’re required to operate in a relatively narrow temperature range. The battery cells’ safety and stability depend on maintaining internal temperatures within specific limits. If the temperature exceeds the critical level on either end, thermal runaway can occur, destroying the battery or, even worse, starting a fire.

Thermal runaway is a chain reaction within a battery cell that can be very difficult to stop once it has started. It occurs when the temperature inside a battery reaches the point that causes a chemical reaction to occur inside the battery. This chemical reaction produces even more heat, which drives the temperature higher, causing further chemical reactions that create more heat.

In thermal runaway, the battery cell temperature rises incredibly fast (milliseconds). The energy stored in that battery is released very suddenly. This chain reaction creates extremely high temperatures (around 752 degrees Fahrenheit / 400 degrees Celsius). These temperatures can cause gassing of the battery and a fire that is so hot it can be nearly impossible to extinguish.

Dangers of Thermal Runaway
Thermal runaway in lithium-ion batteries has gotten some bad media in recent years due to cell phone and hoverboard batteries catching on fire. However, it can happen in all battery types.

In extreme cases, thermal runaway can cause batteries to explode and start fires. In minor cases, it can cause batteries to melt or be damaged beyond repair.

Fortunately, there are new technologies that enable us to make batteries safer and prevent the causes of these chain reactions.

What Causes Thermal Runaway?
Several conditions can cause thermal runaway in a battery.

Thermal runaway can occur due to an internal short circuit caused by physical damage to the battery or poor battery maintenance. The same type of scenario could cause an external short circuit which could also kick off the chain reaction.

Overcharging a battery beyond its safe max voltage (to extend the distance an electric car will run, for example) can permanently damage the battery and lead to thermal runaway.

Rapid charging can also lead to thermal runaway because rapid charging can lead to excessive currents.

Finally, temperatures outside of the safe region on either the low or high side degrades a battery’s performance. This leads to irreversible damage to the battery and possible triggering of the reaction.

While the danger of excessive heat may be obvious, the danger of excessive cold may be confusing. The functioning of lithium-ion batteries depends on chemical reactions. Excessive cold can slow or stop those chemical reactions from occurring.

Preventing Thermal Runaway in Batteries
There are several ways to reduce the risk of thermal runaway in batteries. Let’s look at some best practices and ways to prevent it and protect your batteries.

Proper Storage Temperature
One of the simplest ways to prevent thermal runaway is to store batteries at safe temperatures. The ideal storage temperature for most lithium-ion batteries is between 40-70 degrees Fahrenheit (5-20 degrees Celsius). However, this can differ based on the battery and manufacturer, so consult the label for your specific battery.

Proper Ventilation
Many types of batteries need proper ventilation to maintain a safe operating temperature. Additionally, many of the electronics needed to manage your battery system, also produce heat. Battery enclosures can trap heat generated by the electronics and some types of batteries, if you don’t ventilate properly.

Replace Old Batteries
Battery users not only need to handle and use their batteries carefully, but they need to replace them as well. This is because the chemicals and materials degrade over time.

Some older batteries that have been uncharged or undercharged, may have built up gasses within their casing. This state can easily cause a battery to explode.

If you see a deformed or “bubbled” battery, do not attempt to charge it. Properly dispose of and replace any deformed batteries.

Don’t Overcharge
Overcharging a battery can cause an electrochemical reaction that may result in thermal runaway. Monitoring the charge status of your battery is essential for this reason.


Does a Battery Management System (BMS) Prevent Thermal Runaway?
Most lithium-ion battery packs include a built-in battery management system (BMS). This BMS serves as the control center for the battery pack. It ensures that the battery is operating under safe conditions.

Battery management systems are critical to the safe operation and optimal performance of lithium-ion batteries and help minimize the possibility of thermal runaway.

Battery management systems (BMS) monitor and manage cell voltage, cell current, cell temperature, cell charge balancing, charge control, and internal short circuit detection.

Essentially, the BMS is an electronic system that manages either a single cell or an entire battery pack. It monitors the state of the battery and reports the data. It also protects the battery (or cell) by controlling or balancing the environment of the battery (or cell).

For example, if the BMS detects that the temperature is too hot, it can regulate the temperature by controlling cooling fans. Alternatively, if the battery or cell cannot be cooled and safe conditions restored, the BMS shuts down necessary cells to protect the entire system.

Thermal Runaway is Preventable With Care and A Proper BMS
There is no doubt that thermal runaway is a serious consideration for all battery systems. But with the proper care and management of your system, you can minimize this risk and enjoy all of the benefits of having battery power available to you whenever you want.

Re: Solar Energy, A Complement To FTA by gadgetplanetng: 9:05am On Sep 08, 2023
I got this to replace the Schneider homaya I got for my parents that's brought me nothing but grief (It's been with them for weeks (maybe months) now) since February
I was comfortable ordering it as it's Easun (same brand as the 3kw hybrid I use - which I got here too in 2021).
Package came in, it's tiny, probably smaller than my backup Ceepro so I was a bit bothered but it's a beast in a tiny package.

Installed it yesterday for them and they used it overnight on their weak batteries (planning to get 2.4kwh LFP but Valto doesn't have stock)

This is my third (or fourth?) transaction with Iinnov8 - mostly charge controllers/breakers and everything's working well.

Iinnov8:
Re-introducing the 3000W EASun Pure Sine Wave inverter (12V/24V)

Price: 66,000

Customer review attached

Youtube link video shows the inverter powering an inductive electric cooker, pressing iron, microwave, washing machine, deep freezer, etc



https://www.youtube.com/watch?v=7YgbL4Lw_Bw

Key Features:
- Peak power 3000w; Continuous 1500w
- Offgrid (no charging function. you need an external charger for your batteries). Recommendation avalable
- Consumes very low power (<5w) from your batteries to invert, so you will get more backup time from your batteries
- Protection against overload. It only trips off with an alarm sound and light when overloaded, but returns to normal working when you switch off and on again.
- Protection against surges from sparks, partial contacts and reverse polarity connections

If you are planning to use these devices.. that's mean you don't need the portability..

Get your self a 12V 200AH LA battery for 230K
Hybrid 12V, 1kw for 180k.. remaining change for installation this will provide better power, capacity and upgradable.

You can add Solar in future...

Baba, go back through the pages of the thread and see the list of LifeP04 vendors on Ali Baba.

Contact them and negotiate a price. Some can ship directly to Lagos DDP (Delivered Duty Paid) and you pick at the shippers warehouse or they ship to a freight forwarder of your choice who will handle shipping on your behalf. You use your dollar card to pay using Ali Pay and that's it. The alternative you contact any of the lithium sellers here and buy from them with their additional cut on top. Choices dey.

The information you are passing across is inaccurate. The technology has been around since the 1990's, it didn't catch on due to reliability issues but now that these have been sorted out, it's gradually gaining popularity.
These inverters are called Micro or String inverters.
1. Micro inverter: allows for connection with a SINGLE SOLAR PANEL
2. STRING INVERTER: allows for connection of 2 or more solar panels connected in series.
They basically come in 2 variants, On grid and off grid systems; for naija, the best is the off grid system cos on grid needs Public supply to be available before it works.
And yes, you can buy it on Amazon, Alibab etc.
oweniwe:


cheesy

It can't work like that for now because I don't think the technology is available. The current generated by solar panels is in pulses. It's not steady. If you connect a solar panel directly to a UPS, it'll come on, but maybe 3 seconds after, go off.

That's because the wave is not steady, like zig zag pattern. That's why a battery is needed to store the current from panel first
