Abeg would you recommend OLED screen for someone who wants to replace Pixel 7 pro screen? Those that have used OLED on their Pixel 7 pro before what's the difference between it and the follow come screen
I've bought both screen types. The first was an OLED; unfortunately, it had a line and the fingerprint sensor did not work because OLED screen doesn't actually support it. The resolution was awesome, though. Fortunately, I was refunded.

​The worst is the TFT screen, even though it's the cheapest of the three. Run away from those!

​Then I bought the AMOLED, complete with a fingerprint sensor. But the price difference is like night and day: the AMOLED screen complete with the fingerprint sensor is 3x the price of the OLED.
​By the way, the AMOLED I bought has exactly the same screen resolution as the "follow come" screen because it is "follow come."

​This year alone I've bought two AMOLED screens because I've been careless. Hopefully, I don't ever have to buy another. grin

I swear I'm afraid installing this on my roof... my landlord sef told me he saw online that solar panel dey burn house chaii . Is it true house?

Also, pls I wanna ask isn't this a flat roof, I heard some people said it can be placed on it directly without using that rack
Electricity can burn down a house, too.

So can the gas used for cooking.

And so can the petrol that people keep in their homes to power these noisy generators.

Many have died from carbon monoxide poisoning caused by keeping a generator too close to their sleeping quarters.

Yet, every day, people use these things.
One thing is guaranteed: if anything is misused, you stand a chance of it becoming fatal.

One tablet of paracetamol is fine for that occasional headache, but if you take 20 at once, you already know what's going to happen.

If you get professional to handle your installation, you'd be fine.

Good morning

Please how far these automatic transfer switches (e.g Tomzn ATS). Are they very effective? How about the transfer time? Are they fast enough like an inverter on UPS mode? (Are they fast enough not to damage a fridge compressor?) Please i need help on this. Thanks
If the ATS transfer time is less than 20ms, which most of these ATS falls into, you don't have a problem. Eg I have one from Taxnele that has a transfer time of 8ms, my freezer doesn't restart.

Great information bro.

And at the end, it is either the system is above or below 80% efficiency. In most exams, anything from 80% is regarded as A grade. If it gives above 90% in DC or AC i.e cc or inverter respectively, difference may likely be in little hours of extension.

Most of us love "beautiful boxes" and manufacturers already know our weak points.Hence,some of us will choose aesthetics over functionality. Na who get sense dey..... grin
China has an A1 in aesthetics. They build both beautiful, awesome devices and beautiful BS. The pricing is often an indicator of which one you may be getting.

Hahaha Williion and sms exactly the same Board inside.
Most Chinese hybrid inverter brands (especially those based on the Voltronic platform) are essentially identical under the hood, differing only in their external casings and, occasionally, their display interfaces.

This happens because of ODM (Original Design Manufacturer) and OEM(Original Equipment Manufacturer) manufacturing in the inverter industry. Here's why:


While the ODM factory designs AND manufactures products; other companies just rebrand them while the OEM products IP are owned by the brand who designed the inverter. ODM just manufactures the same product for different brands and change casings (in some instance) and name.


Popular OEM in Europe include SMA Solar Technology (German), Victron (Netherlands), Fronius (Austria), Steca (Germany), Schneider Electric (France)

In China we have Huawei Digital Power, Sungrow, Growatt, Deye, Goodwe, Sofar Solar, Solis/Ginlong, MUST Energy

The US have the following: SolarEdge, Enphase Energy, OutBack Power, Magnum Energy


The China-Based ODMs include
Voltronic Power (Taiwan/China) - arguably the world's most prolific inverter ODM. Their Axpert platform is the engine behind an enormous number of global brands including Mecer, Kodak, Axpert, PowMr, Voltacon, Sorotec, and many others


Voltronic Power & MPP Solar: Dominant Taiwanese/Chinese ODMs whose core platforms (e.g., Axpert, PIP) power numerous global and regional brands like Kodak, Mecer, and PowMr.

Deye, Growatt, Sungrow, Solis, & Sofar Solar: Major OEM manufacturers that also heavily utilize ODM arrangements, supplying custom-branded units and internal components to international partners (e.g., Deye powering Sunsynk).

Must Power, Luxpower, EaSun, PowMr, SRNE, & Epever: Key ODMs specializing in specific segments (like 1–5 kVA systems or MPPT controllers), with platforms widely rebranded across emerging markets, particularly Africa.

Why does that inverter look smaller and sell at a lower price compared to their 5KW hybrid EU version?
The Deye SUN-5K-SG05LP1-EU is better suited for tough environments, dusty, humid, or harsh locations, because it's more enclosed. The Deye SUN-6K-OG01LP1-EU-AM2 has open vents that suck in dust over time, which can damage the internal circuit board if not cleaned regularly.

A standout advantage of the Deye SUN-5K-SG05LP1-EU is that it can feed surplus power back into the grid, something the Deye SUN-6K-OG01LP1-EU-AM2 simply cannot do. Though this feature, which is awesome outside Nigeria, is basically useless here as we no get smartgrid.

The Deye SUN-5K-SG05LP1-EU also switches power faster, in just 4 milliseconds compared to the Deye SUN-6K-OG01LP1-EU-AM2's 10 milliseconds, meaning appliances experience less interruption during a power switch.

That said, the Deye SUN-6K-OG01LP1-EU-AM2 has its own strengths: it handles significantly more solar panel input (9,600W vs 6,500W), making it better for larger solar arrays. It also costs less, which can be a decisive factor for budget-conscious buyers.

Bottom line: The Deye SUN-5K-SG05LP1-EU wins on environment tolerance, grid export capability, and switching speed. The Deye SUN-6K-OG01LP1-EU-AM2 wins on solar input capacity and price.

My charging current is set at 100amp and I will try putting on more power hungry devices because the last time I noticed,I was using an air fryer(1,500w) and the inverter is pulling 1,500w from the pv
If your battery is full why do you want it to pull more power from the PV?

Hello all,
Trust we're good.

Has anybody here heard of Luxpowertek 6kva/15kwh Eco Beast Solar System?

I want to get installer/user insights before I fully decide.
However, I'll attach device specifications/image so that experts can look at and advise accordingly.

Thank you in advance.
There is a reason why many don't go for these type of all-in-one systems is that in the event of failure, getting a repair is usually hard. But if you have a good after sales guarantee go for it.

Luxpower is a brand I've heard of, though never personally used.

The spec you going for looks good, at least on paper.

You decide what you want and either go for it or not. You are the boss

Evening house, please is it ok to combine a 16kwh and 5kwh batteries on a 6kva inverter? I just upgraded to 16kwh and want to add the 5kwh battery in order to have a larger bank. They are both 48v.
Thanks, as always.
These are some responses from an online forum:

Combining different Ah batteries in same bank

Is there any issue with combining a 460 Ah LiFePO battery with a 300 Ah LiFePO battery in the same house bank? They are both Epoch batteries with the same charging requirements.

Re: Combining different Ah batteries in same bank

I Googled your thread title and found info on the Battle Born batteries and Newpowa websites that said "no" to this. Perhaps there are ways to do it but the simple answer seems to be no.

Do not mix two different capacity batteries, even if they are the same brand. The cycle counts of the batteries also need to be similar. If you have a 300ah Epoch for example and have had it installed on your boat for 2 years, I would not recommend adding a new 300ah epoch to that bank. If it's just a few months old (I typically say up to a year) then you are ok.

Re: Combining different Ah batteries in same bank

There is nothing wrong with mixing different capacity batteries of LiFePO4. Brand doesn't even matter. It mattered with Lead-Acid because one battery will work a bit harder than the other, leading to an early failure. On a battery that only is going to last a few years, that is a problem. But on LFP, how hard a battery works plays little into how long the battery will last, which will be decades anyway.
Cycle count doesn't matter either, at least withing reason-5 years or so apart would be fine.

What you are reading that says not to do this is old lead-acid rules and thinking being applied to new technology.

Re: Combining different Ah batteries in same bank

Like Warren writes, the uneven use doesn’t matter much.

However you should only count on maximum power output of the karger battery, without adding the smaller battery. For example if the bugger ine can do 200A max and the smaller 100A max then combined I would only count on 200A, not 300A. If the batteries are the same then you can add as they share the load equally.

For capacity you still get full capacity of both summed.

Looks like I stand corrected. On my setups, I have always kept same age and same capacity batteries in battery banks. I would think that same brand matters, not so much for life of batteries but due to different BMS fighting each other with different cutout points and protections.

I have tested wildly different batteries in parallel last year during a 6 month period and everything was fine. BMS’s don’t fight each ither, they are inky concerned with the cells they manage, not with other batteries.

Of course there’s BMS’s that communicate with other batteries but I am against all such systems for use on boats. KISS.


Is it ideal? No. Is it recommended? No. Will it work? Yes. I have a friend currently running a 7.2kwh battery with 2.4kwh in parallel. It's been weeks now, so far no issue.

so, 9yrs ago to the day, i installed and commissioned my protek solar water heater.
for those who were on the thread back then, recall my review after 1yr on may 17th 2018.

it has really been a bittersweet experience and finally in march of this year i decided to bite the bullet and do an outright system replacement.
this is coming 6yrs short of the promised 15yr lifespan of the solar water heater.

did it serve its purpose? will i do it all over again? the answer is a resounding yes! but not with protek, which happened to be only a white
label product manufactured in china without after sales support.
I love this review.

Most Chinese brands, especially in Nigeria, hate the after sales service. Some even will start fighting you after two months if you have issues.

Which brand did you go for now?

Fremlin:
90v?

And I'm limiting mine to 180v..wow

Anyways that's not really the problem, the issue is that, the voltage been bypassed is unstable and sometimes less than 220v, my freezer works within 220v to 240v, so, once the voltage drops below the 22v, it trips the freezer.

So was wondering if it's possible for the AC input to just charge the battery, while I draw from the battery, with a more stable voltage
Buy a servo stabilizer. My old school 15kva servo stabilizer is capable of boosting 90V to 198V. Anything above 120V is straight 220V. An MVP for mad public supply of Nigeria!
