HeavenlyBang: Pretty weird thing to say without having as much as a hint of that actually being the case. Almost reads like an accusation.
Could you be right? Yes. But asking people to be wary simply because of a broad possibility doesn't sit right with me.
I do agree that Dam5reey1 should state if review units are provided by OEM, though.
This is how Google AI described "Be wary". "Be wary" means to be cautious and watchful, especially of potential danger or trickery. It implies a need for carefulness and alertness in the face of something unknown or potentially harmful. Essentially, it's about being on guard and taking precautions
I have not made an accusation; I was only telling people not be carried away with glowing (or weak) reviews. In reality, no smart person bases their buying decisions on a single review, no matter how glowing or bad. And users' reviews are the most reliable reviews especially when aggregated. I will take the views of a regular user over that of a professional reviewer every day of the week and even weekends.
HeavenlyBang: Lmao, probably the most impressive battery you've tested. Funny that some people were bad mouthing it here a while ago.
People need to be wary of these reviews. It is important to know how the "samples" were sourced. The reviewers also need to declare any conflicts of interest like free samples, paid reviews and commercial partnership with marketers and companies.
Even big companies like Samsung have been known to game the review systems by supplying reviewers with "supercharged" samples. For example, I think Samsung once had a hidden code that detects benchmarking software and then ramp up CPU and GPU to achieve scores that are not achievable in normal use.
It is not impossible for battery makers/marketers to supply top-grade batteries for reviewers and park their commercial stocks with low performing components.
The best REVIEWS are what users on the field say about the batteries and other components.
Pabodo: Good afternoon, Please can one use a Grid-tie Inverter with battery? If Yes, how can it be done and any advice to go for it or not I want to buy one and send to Nigeria, most I see are grid-tie (Sunny Boy SMA) Thank you guys for the good works you are all doing
No try am.
1. I don't know if there is expertise about installing it without feeding back into the grid. 2. It probably won't work. 3. If it works and feed back into the grid, you may be supplying electricity to the whole town or worse get someone electrocuted down the line. 4. 3 may not happen because grid tie inverters work with grid, once the grid is down, they also go down.

If connected in parallel, you will end up with VOC of the lowest panel and possibly lose some efficiency. If connected in series, you are unlikely to lose much, if anything.
solareclips: Hello house, please what is the effects of connecting panels of thesame watts but different VOC together.
skywalker95: I need assistance with my tubular battery. I just topped up with distilled water for the first time and I notice the battery is now dying faster than usual. I ensured the battery was fully charged before topping the water to prevent overfilling it and I have noticed no spilling since I filled it. For the past three days, the voltage drops to 24.5 once the sun goes down and it was not like this before.
Dam5reey1: Checking cells voltage is overrated, for me sha.
The only way to know what is happening to your battery pack is to see the voltage of the individual cells. Cell balancing basically tries to equalize the voltages of all the cells. Without the ability to know the individual cell voltage, you will not know whether your pack is balanced or not. Most battery packs will fail because one or two cells are dead or dying.
spartacus11: Please house were can i get original jinko panel
Call Yemi 0805 two one 5447 one. FYI, that is not me, just someone that I know still have some in stock. And they are original. I bought some from him recently and I checked the serial numbers with Jinko website. He is also a highly recommended installer based in Ibadan.
Firstly, I won’t show you what I prompted the AI, from this response again it’s obvious you don’t know how to prompt AI, and it’s a skill you can learn. AI can hallucinate and give wrong responses if you cannot prompt it.
It’s not the charge rate that degrades LFP batteries — it’s the heat. If you manage that heat properly, charging at 0.5C or even 1C is not only safe but often optimal for many systems. Lab-tested cells and manufacturer data confirm this across multiple studies.
If they bought Grade B or C cells, I’m wondering if you are the one that sold it to them or you are the manufacturer or the person that coupled it, that you are telling them 0.2C is better than 0.5C or 0.1C for longevity.
Your write up on lower discharge rates (like 0.1C) extracting more capacity from a battery?
Absolutely. Lower discharge rates often increase usable capacity, because: • Voltage sag is minimized • BMS doesn’t cut off prematurely • Cells reach deeper into their nominal capacity
This is not in dispute. But it’s also not exclusive to slow charge—it applies to load-side efficiency. A well-calibrated inverter with good low-voltage cutoff can also help with that.
The driving analogy doesn’t hold — battery degradation isn’t governed by speed alone like a crash is. It’s about thermal load, SOC time, and chemistry-specific behavior. LFPs are engineered for higher charge rates, and if you’re managing heat, 1C is just cruising speed — not a crash waiting to happen.
Your driving analogy doesn’t quite translate to how battery charging works — and here’s why:
1. Battery charging isn’t a linear safety-risk scale like car crashes. • In driving, risk increases exponentially with speed because kinetic energy scales with the square of velocity (E = \frac{1}{2}mv^2). • But with batteries, degradation doesn’t follow this pattern. It’s influenced primarily by temperature and time spent at high state-of-charge (SOC) — not current alone. • A well-managed LFP battery can safely handle 1C charging without measurable degradation if voltage and temperature are properly controlled. That’s not comparable to speeding at 180 km/h, where you’re at risk no matter what.
2. LFP cells are designed to handle higher charge rates. • If we extend your analogy, LFP cells are more like performance vehicles built to cruise comfortably at high speeds with full safety systems. • Charging them at 0.2C (the equivalent of crawling at 10 km/h) when they’re rated and certified for 0.5C to 1C is unnecessarily restrictive — and can actually underutilize their design efficiency and lead to other forms of stress.
3. Slow driving always increases safety; slow charging doesn’t always increase longevity. • Your analogy assumes that slower is always better — but in battery systems, it’s not that simple. • Charging slowly at 0.2C extends the time the battery spends at high SOC, which is scientifically known to contribute to long-term degradation through electrolyte breakdown and side reactions. • So ironically, your “safer” 0.2C charge may lead to more stress, not less — especially if the system just floats at 100% for hours.
4. Battery systems have built-in protection — the equivalent of seatbelts, ABS, and collision warnings. • LFP batteries with proper BMS support include: • Thermal sensors and cutoffs • Current limiters • Voltage controls • These protections actively regulate and prevent unsafe conditions, making 0.5C to 1C charging not only safe but often optimal — unlike a human driver at 180 km/h who’s still vulnerable no matter the airbags.
Lastly, all this statement on ‘Nigerians love to do these and answer like this or that’, well I hope you kenyan and not Nigerian?
It is true that HDDs have higher data recovery probability than SSD. However, that is where all the advantage ends. SDDs are faster and have smaller failure rates than HDD. And by the way, a good computer person will tell that if you need to recover data from a failed HDD or SSD, then you are not supposed to stand near any serious data in the first place. A serious computer person will know the rules about data backup. If your data is important to you, you should have multiple backups, onsite and at lest in one offsite location.
Data recovery is now more about forensic or accident investigations. Bottom line: SSDs are far superior to HDD, just like Lithium is far superior to Lead Acid. And like someone pointed out to you, many of us on Team Lithium were once on Lead Acid. I for instance, started my solar journey with Trailer Batteries about 1998/9 before graduating to GEL/AGM and then Tubular before finally joining Lithium train. Nothing will take me back to Lead Acid.
bassdow: Similar thing on Lithium batteries also as with age, they drop in quality. apart from how long they have stayed before getting to the markets, you don't know how long they stayed on Shelves before you came to buy it.
You can't compare a lithium battery manufactured in year 2014, and bought 2-months after, with another that's bought 3-years after.
If you think I am over talking, go to where they sell laptop batteries, (or any Lithium battery) tell them to give you a new one, check it's date of manufacture.
Really have no issue with Lithium battery chemistry, but the fact people keep promoting it like it's the next best thing to ever happen to Man, like it's got no downsides of it's own.
AnyOne in Computer world would tell you how lovely SSDs are compared to the likes of Hard-disks, and it's siblings BUT na when you run into Data issues (corruption / damage / loss) you go come to appreciate Hard Disks. As in chances of recovery are much higher with hardDisks, than SSDs. In fact just leaving the SSD for long without powering it on, is enough for it to slowly loss data. But people (mostly uninformed or sellers or manufacturers) would keep singing to you how fast SSDs are compared to previous alternatives.
They would tell you how your Computer would boot-up in less than 2-seconds; as if it matters to large percentage of people. I could run my work computers (Laptops and Desktops) for months without ever restarting it. What about Servers, which are only restarted when need be.
Yes SSDs has got it's PROs, but got it's CONs also. If you come preach to me only the PROs, with no mention of the CONs, I go get your time.
if there are SSDs, and even hard-disk (which is slower than SSDs), why do big companies still use Tape Drives which are even a lot SLOWer than hard-disks which are in turn slower than SSDs ? Its nothing other than the fact everything got it's strong and weak points. You just need know where and when to use which.
Make una continue to dey argue, me go try continue to dey get time to dey type epistles.
You can refurbish a Tubular / SLA / GEL batteries, and give them a second chance; same way you still got chances to get things out of a non SSD disk, You can't, or have super Less chances with SSDs, or Lithium batteries.
What about safety issues with regards Lithium battery chemistry ? They rarely tell you those.
Who knows, a lot of people arguing here, might only be using Lithium batteries in their phones or laptops, not even as Solar battery, but still want to belong. Some of us never see 1-miillion before to begin with. Abi no be banks talk say a greather number of Nigerians no get up to 500,000 naira for account.
Funny thing is, if I be una, I no go bother because lots of people don't read. When I first saw this thread, I took time to READ through over 500 pages but you go see people wey go come, read 1 or 2 pages, and begin ask questions already long discussed numerous times. Even when you ask them to read through the pages, na lie. they so so lazy.
Below is a good example on why welded busbars is a terrible idea. It’s just a companies way of saying don’t touch anything inside our packs.
EvS are a terrible reason to defend welded busbars, ev companies don’t want you opening their packs and they also want the pack very secured in case of an accident! Heck, even their CAN communication are not standard and are very proprietary!
In this modern day where the world is going in the ‘right to repair’ direction, companies are still making this kind of product decisions. This is no different that iphone 13 and above requiring replacement parts approved by apple themselves for it to work well, you can’t swap a faulty iPhone part with another one sourced from the same iPhone without an error in the software. Same goes for display, and face id sensors.
Emmalex83: Yes sir. They have enough storage tanks. Like how many solar panels and inverter capacity did you think can handle 12hp in total to pump water during the day. Thanks so much
They don't need to run 12hp simultaneously. They can run the pumps sequentially or at most 2 or 3 at a time.
HeavenlyBang: Tricky. They can pump in the afternoon to handle the evening usage but the morning one has to be handled entirely by batteries.
Also sumos are tricky, since most draw a lot more than their rated output. For example, this 12HP is about 9kw on paper but in real life could be as much as 15kw.
What I'd tell you is to go there and get actual real life data on
- Power draw on each sumo - How long it takes to pump full
You need a watt/clamp meter for the first one.
Their best approach is to get appropriate number and sizes of storage tanks and pump water exclusively during the day. Get plenty of solar power and get a little lithium battery to ensure smooth power during the day.
ojeysky: I am well and good Bro. I do pass by once in a while....good to see the growth (just like those that joined the thread before me will have said as well ) Thanks
Yet, this "answer" is as dubious as that previous "father of the internet" nonsense. The man has probably done well for himself, but this hyping will embarrass a true innovator.
owobokiri: Y'all finally found an answer to "The Father of The Internet" tag that irritated you guys for decades now? Nice try tho..
Iinnov8: As the rains fall in torrents and your inverter stands the risk of being affected by lightening strikes, don't forget that we got you covered with our 3000w Pure Sinewave EASun inverter.

xtremeidea: are you using wired via the ports or wireless via BLE?
Please I would appreciate if you can put me through on how you connected yours. My esp32 won't just connect to the Mac address. I have swapped multiple esp32s. Same issue.
2. You can get two manual switches and use them to select which battery you want to use at any given time.
3. There are factory made battery isolators and combiners that you may buy which involves merely turning a knob to select a battery. This can be manual (Pictures 1 and 2) or automatic (Pics 3). These are available on Amazon. I don't know if you can get them locally.
4. I used to run something like this when I was transitioning between Lead Acid Batteries and Lithium.
i want to add a second battery to my inverter set up in a way that I can switch between battery 1 and battery 2 at anytime. Both battery will use the same source for charging (same Solar and Grid) and I don't have a problem charging only one battery at a time.
I cant merge because both batteries are different sizes and manufacturers. And I don't want to use two inverters .
Is there a change over switch that can change the battery in use between battery 1 and battery 2, just like NEPA and Generator style?
The bolded is not true. If you can not face South, face the North if there are no trees or buildings shading your panels. East and West will limit your sunlight exposure mostly to morning and evening respectively. The rest are on point.
casualobserver: It is not, if your roof is facing North for instance you will get very poor production the further North you go because Nigeria is in the Northern hemisphere. For Nigeria the optimal direction is a south facing roof. The next best is west or east facing. West gives you better production in the evening and east better production in the morning. If your roof type is the very steep angled send down the rain type roof and you live in Lagos, your production will be drastically reduced. The ideal angle of your roof is the angle of the latitude of your location. The more your roof deviates from that angle the lower your production. In Lagos the latitude is 6 degrees. If you install solar on a a send down the rain roof in Lagos, you will always struggle to get good production. The further north you go the better it becomes with the same roof angle. This is science.
That’s why the location direction and elevation of the roof matters when giving production figures.
As an example, below is the estimated yearly production of a 10kw system facing south with 45, 15 and 6 degree angles. The highest production is at a 6 degree angle which is the latitude for Lagos. Not much difference between 6 and 15 degrees but once you start moving into steep roof territory it starts to matter significantly.
The heat this time of the year caused a significant drop in solar yield. Always remember to factor in the temperature coefficient when purchasing your solar panels so as to have a realistic yield estimate when you factor in the different temperatures we experience throughout the year.
