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.

Nickyblithe:
Good day all
Im looking at going for the Deye inverter. I would appreciate recommendations on good inverter brand for 1hp AC and chest freezer to buy. Thank you

Deye 6kva not a bad choice.

Can handle both your AC and freezer.

Gshems:
Na 8k be the cheapest I saw in arena

Buy. 5k is for like 25mm

Bankyshinani:
I know all that... what i am talking about is when my battery is like 40-50% and I have never seen the charging current go to 50amp before it is mostly at 40 something amps

Oh. I see.

Bankyshinani:
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?

Heemcelph:
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

chadbasin:
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.

Thanks for the responses... much appreciated.

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.

twinskenny:
10kva deye inverter

30kwh lithium battery

16 no of 620w jinko

Location Osogbo

Installations fee 60k

Some client though... I can't even reply to this... I know some installer will sure take up the job

I guess the client is very generous.

Why not ask for free installation?!

Ezimuoh:
You been dey on AC on top Tubular Battery?

People do it

You need to see what people subject their system to out in the wild.

I've seen things.

Surprisingly, some works, but sadly not for long.

There are satchet inverters out there whose rated power is what you get. It just cost higher. A friend has a 5500w type which he uses to weld. You get what you pay for.

SourYoghurt:
good morning, is there a way to contact you, I'd have sent an email but this account has a throwaway email address.

D-1ghpzypc@maildrop.cc

You can reach me here in like next 24 hours. Cheers.

SourYoghurt:
it turns out that what he bought was for AC

Are these SPDs connected to earth? How good is the earth? Find attached the resistance of an "earth" in someone's house.

GeorgeD1:
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?

twinskenny:
Installed today!

6kva deye hybrid inverter

5kwh deye lithium battery

Note. Client to add more kWh of battery later on.

Glad to see you are now team Deye!

Nice.

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!

bassdow:
maxBudget is 40,000 naira and that's a very hard max. For very very exceptional devices, could be willing to go up to a max of 50,000 naira.

I doubt you'd be able to get a usable phone at that price range, even if you buy in China.

The only phone you can get in that range are these low quality phones which claims to have 200GB ram which is as slow as snail and heats up like a volcano.

bleexInc:
Thank you. Will it work with my battery? I use LPBF48300

Give it a try and inform the house

Machiny:
1. Can anyone suggest an inverter friendly water heater?

2. How many water heater would be suggested for a 16 rooms guest house. Note the guest house is off grid

Heating takes much energy. No way to circumvent that.

Just calculate the heater you have and buy inverter as appropriate.

bleexInc:
Hello house,
Kindly assist.
My Growatt 6kva inverter is not communicating with Felicity 15kwh battery. It only works when set on user defined mode.
Has anyone had similar experience?

This is how I was able to run communication on Felicity FLA48200 battery with a Growatt


Set Felicity battery DIP switch to 10000

Using Felicity comm wire connect the side written "Felicity solar" to the Felicity battery and Connect "1,2" side to BMS port of the Growatt inverter

Go to setting 5 and select Li and use Protocol L04

osayuwamwen:
pls i how do I disable that beep sound that comes up when pv input is coming in the morning and Going out in the evening that noise the wan gv me BP once I they hear the sound I go tink say something bad they happen to my inverter until I go close, I can't find how do disable it in settings in luxsun inverter

Do it the old school way. Open the inverter and put a PVC tape over the buzzer. Viola! Problem solved. Just know going forward no other alarms/beeps

Edit: my bad, saw someone already said this. Old school still works

sirneyo2005:
Please does this mean that the cell in red is bad because since I bought it I have been experiencing this I thought after long usage it will auto balance and work like the others

It should be close to each other. The red indicates the battery with the lowest voltage. But as it stands, it's not looking good. Charge it full and observe if this continues. Is this a DIY build? I noticed the sense wire resistances are off which indicates wire length of difference sizes or contact torque of different magnitude.

If all fails, consider top balancing the batteries, that is put every call in parallel and charge to 3.60 to 3.65V.

JoeSef0:
What's going on with solar panels prices lately. Jinko 630w is now 145k in market here in ibadan

1.China Tax Policy:China cut export tax rebates on April 1, 2026, making panels more expensive to ship.

2. Rising Material Costs:The price of silver and silicon used in manufacturing has spiked globally.

3. Inventory Gap: "Cheap" stock from 2025 is sold out; new, pricier shipments are just hitting the Nigerian market.

4. Supply Chain Delay:Production pauses during the Chinese New Year (February) created a mid-year supply shortage.

Tdoctor:
I salute.
Please what material should I use to prevent water leakage between panels in a solar panel car port?
Bassdows, twinskenny, anyone

Roofing sheets

twinskenny:
I tell you! And no single crack!

This is not as easy as it as it seems, especially at that panel size. Well done

bassdow:
What makes you think or Say so ?

In fact I prefer climbing Slate (Asbestor) roofs than all those Aluminium roofing sheets most of which are as slim as cheap Tissue paper. Most are less than 0.55 in thickNess.

AnyOne with enough basic knowledge shouldn't have much issues installing on top such roof.

And these old roofs makes life much easier for Us than all these New generation SendDownTheRain styled roofs

Oh, that's interesting to hear. How do you secure the solar panel on the roof

jstemmanex:
Pls explain this chief. I'm about to roof a building tomorrow with this material and solar is what's planned for the building.

Any disadvantage in using this type of roof?

Apart from the fact you can't really use water from the roof, you run a risk of breakage during installation. Apart from these two issues I don't really think there's any other minus in using asbestos roof.

twinskenny:
So we set this up over the week

20kva inverter

60kwh lithium battery

24 no of 710w Jinko

installing on an asbestos roof? This is almost mission impossible. Good job!

The length these scammers go to

bassdow:
I kukuma love ma kinda person. Wetin concern me with non Sticky pot or whatever. I keep things simple and minimum. No be evrything dem advertise person suppose pursue.

e get reason why some kinda health issues are attracted to people of certain wealth grade.

The pealed frypan is what we have been using for years now and got a set of new ones last December.
Ah! Una no quick talk oh.

Many don't know the dangers of using non stick cookware when the nonstick material starts to peel, flake, or get deeply scratched .

That is where these multi-million naira entities created by the FG should come in- but alas they are just there to make money.

Does anyone know how to connect this charge controller to a computer to adjust and read settings? I know it does MODBUS but I don't see it implemented by anyone. Any help is welcome.

When you finally find the answer to this lemme know.

where did you buy the stainless pots? The ones I have been seeing around are the granite pots

I bought it in China.

So far I don't have an induction cooker. Will likely get one soon.
