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.

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

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.

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.

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.

Keeping it old school sometimes saves a lot of stress in some of these things.

adimx:
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.

adrusa:
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.

Penuelseun:
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.

brightk:
Does your stainless steel cookware work with your induction cooker?

I'm yet to buy

Unfaized:
Indeed knowledge is power. Imagine deliberately sampling & selling a health hazard to the public in the name of used items.

The other day I came across a video talking about how Talcum (The famous ingredient used in our very popular powders) has been found to contain a highly carcinogenic substance.

May God help us all!

Nigerian SON is truly not doing anything to ensure any standard in anything being brought in for sale into Nigeria

iraybuju:
Hello ladies and Gentlemen please clear the floor for team Induction cooker!!! Well just to chip in my little contribution for those using non stick magnetic pans please pay attention when it ages or coating start to pill off its very dangerous to the health it can course cancer. If possible just buy the plane still or stainless pans. Respeck all….

Yeah, stopped using all my non stick cookware this year. I'm now team 304/314 stainless steel cookware. Health is wealth. Crazy you'd see old nonstick cookware, well peeled, on sale as Tokunbo in Nigerian markets. Knowledge, they say, is power.

Gshems:
Please guys I need suggestions for a 48v 5kva inverter and 5kw lithium battery

Get a 6kva Growatt inverter so you can overpanel in the future.

Get LVTOPSUN 5KWH or any of Valto, Reed or Deriy Battery

I love the Chinese. Sometimes they don't just give a fück about aesthetics. This is someone casually using BYD blade cells (15kwh each) and even built contraption to get it hanging off a wall

Flies wire as if he had once worked for NITEL/NEPA.

Anyways it works, that's all that matters

Famicare 3.5kva/24V with inbuilt PWM Solar Charge Controller and 2units of 220Ah Tubular battery available for sale. Total Price = N600,000.
Location: Ibadan. (Suite 54, St James Cathedral Shopping Complex, Labaowo Ogunpa, Oke Bola, Ibadan).
Whatsapp: +2348063988765

Is the tubular battery new?

AyarmBoye:
i understand as all the loads will be using the power the solar is generating….

I’m hardly at home during rhe day so no loads ….
My question is what if the battery get full before I return home I hope the charge controller can cut of the supply to avoid overcharging of the battery? And what happens to the power the panel keeps generating when the battery is fully charged?

The answer to all your question is actually in the name of the device- a solar charge controller. It literally means it'd control the charging coming in from your solar panels. That means once battery is full, it'd enter float (stop charging and maintain a particular pre defined voltage).

bassdow:
...but by the time they hear the PRICe tag, dem go jeJeLy like the sound of the FaN

😂

You have a point, premium products often come at a premium cost.

Litewriter:
😂😂
Don't be surprised that there are low frequency inverter that consumes lesser idle current as low as 20w. Make ya findings

My 4kw Schneider no load draw is 40w.

Growatt 5000ES hybrid has a no load draw of 45w.

Some LF inverters are not that wasteful.

ask4bk:
Some of these old inverters stay completely silent in normal user except when it hits like 50% of rated capacity and the fans activate.
But these new ajebo hybrid inverters will just have fan constantly on even on low load, and will increase the fan noise with more load hitting it.

These old inverters are just so robust and working for 5-7 years without any single fault

The old inverter don't usually multitask and form factor is usually bigger. Cramped in electronics deserve ventilation

Newer hybrid inverters does three functions...charge battery via mains , has a solar charge controller and inverts. All these generate heat, making that fan necessary, but if you hate fan so much, some premium inverters are out there with huge heatsinks and no fans eg Goodwe, Solis, Sigenergy etc

brightk:
Are we neglecting the amount of energy in these banks? u are converting from ac to dc, where are the losses in ur calculation....

I never knew that charging phones consumed so much power until a friend opened a charging shop near school. He runs at a minimum of 600W even on days when there aren't many phones. With 78 charging points, the wattage adds up pretty fast. He currently uses two old 220Ah tubular lead acid batteries paired with four 550W solar panels. Eventually, he will have to swap out those old batteries for lithium ones.

tziz:
Wow. Will 25mm/sq work?

16mm² can work too, you asked for the ideal size. Ideal is 35mm². But if you have 25mm², go for it.

tziz:
Please what's the ideal cable size to use from battery to Inverter for my 12v 1.5Kva Haisic Inverter?

35mm²

waleayeni1:
Fair enough. You appear to be a very diligent student of DiY, judging by the neat arrangement of your setup. I have sent you an email. Please share your WhatsApp number for a closer collaboration if you don't mind. Considering going for the bigger panels (725w) but the weight I see of those things are scary. Make e no go bring my roof down. Plus charge controller that would give me peace of mind no go cheap. With your help, I am more assured.

715w panels are pretty huge and heavy (37kg)

But it's all good.

It works ok. Just get a tier one panel: Jinko, Longi, Trina, etc.

xtremeidea:
Hello Guys, please what Voltage protector do you guys use? i got one Joyelec like this and it's not cutting but allowing voltage over 240 pass through. i have done the settings multiple times.

Try POSMITH.

You may get lucky. If all failed, get a servo AVR and call it a day

waleayeni1:
Thank you for the prompt response. This your setup is too clean. Are you by any chance an installer? You are my lastest favourite person on nairaland at the moment. Abeg permit me to be your curious student at this time. What is your Solar array strength. What is the size of your battery bank. Is there any part of the system that you wish you had done better? What is the relative cost of the components used outside the inverter? I would be ecstatic to get your feedback

My solar array ain't that much. Just 9 panels. 4 nos Jinko 380w and other random 5nos 250w panels. Battery is 14.3kwh, I built it myself. I like to DIY things...with enough patience you can do virtually anything....except, maybe, surgery on yourself

I wish I could add more panels, but sadly I can't.

Tdoctor:
This setup is beautiful. Where did you get the wire pipes (the name just fled my head)?

AC PVC duct pipe, a leftover of a big job done by a friend.

waleayeni1:
Thank you for your support thus far. It turns out that the 4048 i got is bad. Do you know any trusted repairer in Lagos that can assist to fix it? Also. please i would appreciate it if you can snap and send your setup so i can replicate with my SW 4024.

I don't know of any other trusted repairer unless you'd visit Schneider head office in Lagos at Ikeja Off Adeniyi Jones 1 Tunde Gafar Close. I'm sure you'd get info on repairs there.

Guys,
I just installed 12KVA felicity inverter with 15Kwh felicity battery.12 X 440W jinko panels connected in series to PV1 and 10 X 590W jinko panels connected in parallel (5-5 in Parallel) to PV2. The inverter has an inbuilt mppt so no need for external charge controller.Anything to be worried of.Just seeking opinions incase I missed something

Isn't that 12 panels in series close to 480v for the panels in series? Or am I missing something here?

Are you not better off connecting the 590w all 10 in series? That should be about 442v. Pretty close to the 450v which I think is the closest you could safely get to these 450v-500v high voltage hybrid inverter.
