Only trying to say I needed non Hybrid inverters.

Though if I get a hybrid inverter, might have to strip it down to bare minimum though not sure how possible BUT major focus is for non Hybrid inverter

Hybrid simply means it has internal mppt and communicate with grid.
When you say you want a non-hybrid inverter to use like a hybrid inverter as u said in your original post, you wan chook mppt or solar harvestor inside am? Abi you used the term hybrid wrongly again as many people often do here?

Pakistan’s 22 GW Solar Shock: How a Fragile State Went Full Clean Energy

Michael Barnard

[b]Pakistan isn’t the first country you’d expect to crash the global solar party. But by the end of 2024, it quietly rocketed into the top tier of solar adopters, importing a jaw-dropping 22 gigawatts worth of solar panels in a single year. That’s not a typo or a spreadsheet rounding error. That’s the kind of number that turns heads at IEA meetings and makes policy analysts double-check their databases. It certainly made me sit up and take notice when I first heard about what was happening in mid-2024.

No be same country the locals went to a solar harvest field and were breaking hundreds of panels with sticks and rods by both men and women coz someone told them that the installation of panels is interfering and stopping rain from falling down?

After doing such mega projects, they should endeavour to educate the people.

There's a reason solar renewable energy is used in 3rd world countries more than 1st worlds who already have stable energy albeit unclean. It's when your power is epileptic that you've no option than to adopt more affordable and accessible options like renewable energy.

I am looking to perform a little experiment where I get to use a standard Inverter like it's a Hybrid inverter.
I mean with regards the fact there are inverters that could function without a battery.

Issue be say I no get inverter wey I fit use do that kind experiment. If e get any body wey get inverter wey we fit use do that kind experiment, abeg make e try contribute abeg.

I want something wey be say if e spoil along the way, I go fix am continue. I no fit comfortably do that kind thing with expensive ones.

What do you mean by using standard inverter like hybrid inverter? What is standard?

Lemme pepper felicity haters.

This is the best low frequency hybrid inverter in felicity line. The IVGM series. 5,8 and 10kva.
Has same IP65 features against dust and water like the IP65 Deye, but more affordable.

Wahala is that it came into Nigeria and it got finished immediately.
Same with their new charge controller that now has inbuilt WiFi. Nigerians finished them immediately.

When they make this developments, you begin to give your solar equipments wey dey house side eye like you can't wait to change them.

joelbooks:
Do the math. If 99% of men cheat, who are they cheating with?
Other men? No.
So, who then? Women, of course.

That means:
99% men cheating = 99% women involved.

Conclusion: If 99% of men cheat, then 99% of women cheat too.

Only people in commited relationship can cheat. If a married man cheats on his wife with a single lady, only the man cheated. A single lady cannot cheat. A single person can't commit adultery. For them it's fornication. For a married man or woman it's adultery or cheating.

I didn't believe i had to explain this

BangaRice:
Good morning fellow enthusiasts,
I need the most budget friendly inverter that can

1. invert 12V DC into 220v AC
2. Use Grid power to charge backup battery when available and switchover to solar when appropriate.

Th set up is just 300w panel, PWM controller and 100AH battery.

{PASTED AGAIN FOR ATTENTION}

You may almost certainly not get an answer. People here have left such small systems which includes pwm for a long time.
Just go get any 12v inverter that has charger function and that's all.
Sure i didn't answer, but at least i responded 😎

I don't like it when people make good comments about Abuja. You want to be attracting population and Lagos nuances to Abuja ?
Pls leave our Abuja alone.
Its not a good place to live in.
Dem de chop human being for here.
Remain in Lagos pls

Good evening house. Please this JA solar and ZN solar on fouani, are they okay. I can't find any jinko there again and I need an alternative

you’re been too paranoid. I don’t know how old you are but I’m sure you’d probably be long dead before your LFP cells hits 70% DOD.

Everybody should just do whatever they feels is right for them.

Not every caution is a clinical paranoia coz be like you wan talk se i don de mad 🤣.
You take cautions for your personal car coz you want it to last and not coz you are paranoid.

Meanwhile I'm 38. Saying i won't see my battery get 70% DOD mean se you wan make i die before 60 years . Oga, u no good aswearrrr lol

Dam5reey:
Oga, you are just emotional, your Analogy no follow!
This is a product review!

Only that it is a wrong product review.

As emotional as it was, you know se e go pain you if dem do am to you. But e de happy you now as you do am to another brand using a product that THAT IS NOT THEIRS

fuckboys:
I'm sure you know what absorption and floating means?

At what voltage should n lfp cell be done absorbing and at what cell voltage should it float?

If you knew what the absorption and floating really is you'll know that the terminology applies to lead acid. Its only borrowed into LFP now.
LFP just has a charging voltage which you may call bulk or absorption from lead acid terms.
There are 1001 cv requirements based on brands and cell tech. Many datasheets will say 3.65v in the west. When they make it specifically for Africa and Asia they reduce. Even in the west people change their settings to lower cv. Practical setting for cv 3.45v-3.5v.

LFP doesn't feed floating for simple reason that LFP doesn't like to stay near 100% for long since it reduces lifespan. In the west, many let their cv stay for 6mins when complete and let it go down and settle at 3.35v. If your inverter forces you to float, set it at 3.35-3.40v. That's sweet área for us for long lifespan.

But since e de shark us for head to de see 100% for battery screen, we love to leave it to float near full so that when sun goes down we are near capacity. I also set my cv and float to same though i know its not best practice.
That's why i put cv and float low at 3.45v. I know the disadvantage but me too want near full by evening. Just fooling myself coz in most LFP discharge curve, even that 3.45v is almost same as 3.35v.

obitobe:
This is my cells right now, I guess they are well balanced.

Over balance de worry am.
Keep this settings pls.
Don't let anyone deceive you to go to higher charging voltage.

Dam5reey:
What are you saying oo
My 52 usd is at stake, send me original product if you are interested in cleaning up the air, else you are just part of the 1000 Adviser, Zero help!

I don't work for them na. You are only expected to be human and do the right moral thing after wrongly tarnishing a brand after your mistake of lack of research.

You are a solar guy who have given yourself good name for years. If a scammer claims to be you and uses ur name to steal a project where he installs rubbish... It catches fire after 2 weeks and the scammed client goes online to say Solaris surge or Dam5reey is the worse solar installer with video proof of his burnt setup and house. A project you knew nothing about oh.
Someone recognises the scam and tells the scammed client that the guy who scammed him isn't Dam5reey oh, he scammed you. But clients says I don't care, let the real Dam5reey come and install a new setup in my house for free to save his name. My 6 million is at stake instead of saying, ah, i was scammed by one electrician Femi who isn't Solaris and I'm sorry for spoiling the name of the legit company. I sure you go like am.

See as you don make me write long super story to prove a point wey no concern me 🤣🤣🤣🤣🤣. Just be human.

Dam5reey:
The company should find my video and send original one.
I bought that toy for 52USD, na me go still correct what?

😂 Did you even read your comment? You were deceived by fraudsters and went to buy a fake that doesn't even exist in their catalogue from a cloning company. And you expect the real company to come and save their name and send you a good product? 🤣🤣🤣🤣.

"Guys I've just realised that i got scammed and bought a non existent fake version of this company's product. I retract my comment about calling the company product a toy until i get the opportunity to test their real product someday"...

Dam5reey:
Always buy ke, these things are not cheap,
Buy and send me one for science.

Lol... But at least you do acknowledge what i told you about the elejoy tester - that you got a cloned fake device.
One day you may need to correct the wrong notion the fake device gave you and which you told your audience so as not to destroy their good brand quality.

favouredbymercy:
It is recommended that for battery type you should select 'user' and then input battery recommended charge voltage parameters. Your DIY battery is from what source? Because the 55.4v i see here is low. Most BMS cell balancing starts from 3.5v per cell, i.e 56v for a 16s pack like yours. And if your balancer is passive, you would need to go even a little higher.

55.4v is low? Omo 😁😁. That's 3.46v which is over 90% of full charge. That's a very ok charge voltage.

Don't forget that LFP maintenance are rated based on 25ºc. That's temp for summer in Oyibo land. I'm Nigeria that's a cool temperature coz 90% of 365 days in naija we are above 25ºc ambient temp not to talk of temp of cells in the park as calculated by bms.

Where i stay ambient temp gets to 42ºc. If you charge regularly even at 3.5v in our high temp you are reducing LFP lifespan. That's a fact.

I always set active balancer to start balancing from 3.4v. My max charge around 3.46v. You'll not gain anything from 3.5v to 3.65v apart from heating ur cells and reducing lifespan.

Dam5reey:
Na only emotions people them Dey take Argue, Facts no dey.

Chief, seems you are solaris surge (or something like that) on Tiktok.
Weldone for all the efforts you do for this solar field.

You've always said that one day you'll test DIY battery packs of valto and mrreed to confirm the grade A cells they use for their set up. We know they've been tested by them and went above stated ahm capacity. But from a 3rd party will be cool for scientific and fun purpose.

Lastly... That elejoy mppt tester you got is the wrong one. Yours is showing EY1800W with green body outline. Elejoy doesn't produce anything like that. Its a fake knockoff. I saw an American guy testing with same one you have and he tested even when panel was facing down and it gave 500w+ 🤣🤣. You all bought the fake.

Always buy the EY800W that has red body outline. It's the best.

When will it dawn on you all that Nigerians don't care again about this show?

I don't even think anyone knows who won that of last year. That's how Nigerians are beginning to get serious and avoid this distractive show with no value

brightk:
i would rather pick a deye 12kw over growatt 12000 Es. but factor in their pockets..

As you sef typed this Deye 12kw, your heart no cut small for me?
No be yahoo boy get the facility 😭😭

brightk:
maybe you should visit the location and do some analysis.. check each devices consumption, peak load hrs and off peak load hrs.. i think u can draw your conclusion from there.

You are right.
But assuming (we are doing assumptions now) the load is truly 5kw at peak, would you suggest a high frequency inverter like Growatt 12000 ES (12kw), or you would prefer a transformer based inverter coz of surge current from hospital inductive loads?

dollarnaira:
Tell them to go and buy Mikano generator. End of discussion!!!
No go put urself for wahala oo. Them go spend tire with complaints..

🤣🤣🤣.
Na the diesel dem de spend on the mikano wey dem already get dem wan run away from.

xzynwa:
From the total power consumption of the appliances listed which is 5910w, you should go for a 10kw or at best 12kw inverter.

The is reason is quite simple. Considering things like safety factors, assumptions based on you not physically present for on-site assessments and likelihood of the hospital using other appliances not earlier listed (remember, when this inverter sleep starts getting sweet the user will like to throw in appliances not earlier budgeted) 😴 😀

A likely pointer to the inverter size could be the size of the generator used to power those loads. Get the generator power capacity and oversize it slightly and you get the answer to it.

A 6000w load at 6 hours would be 36kwh. At 80% depth of discharge you will need 45kwh of battery storage to achieve that. Trust me, you will need more than that.

Since there would be grid power to charge the battery, you may get by with roughly about 15-20kwp of solar power.

Mind you, the above suggestion is based on you relying on the information provided by an organisation that may beyond the listed appliances, and stressing the setup beyond what an informed user may decide to do.

Finally, a job like this requires one to have an on-site inspection and critical questions asked than relying on assumptions to avoid stories that touch and "solar na scam"

Simple truth.
Thanks

bassdow:
Not to consider days when they battery bank is yet to recover fully from previous day's usage or days of poor weather.

Also as for the freezers, who knows if they are the types used in temporarily storing bodies or mayBe blast freezers sef.

Let's not assume since a hospital ain't a household.

In situations such as this, after studying things, even going there in person, I would give 3 quotations:
1. The actual quotation (e.g 10kwh)
2. The actual quotation with 50% extra (e.g if 10kwh, this would be 15kwh)
3. The actual quotation with 100% extra (e.g if actual is 10kwh, this would be 20kwh)

Also you try to put as less pressure as you could on the batteries. MayBe even make the setup 2 parts where 1 part handles a set of loads while another handles a set of loads.
Also hope these don't include MRI machine sha.

Truth is, a lot of times, don't rely on the client giving you their full load hence you need factor that in as allowance.

I put brief explanations and suggest they grant me a face to face opportunity to explain further. this is necessary in organizations where there are lots of bureaucracies.

I like how you are reasoning the "what ifs".
When a hospital says freezer/fridge, it may not mean our household freezers. It could be for bodies or any thing. I didn't go to check it, but the person that did said 500w for each. Could be right or wrong. As you said, until one goes and is sure. There are freezers that are cold rooms. You walk into the freezer with your entire body and inside is like full self contain room, but it's a freezer. They can consume power in kws.

HeavenlyBang:
Keep in mind that if those fridges are actually 1500w running power and not inverter fridges, you could be dealing with up to 7kw starting power. Add other appliances and a 10kw inverter is what you should go for.

30-35kwh of batteries sounds about right.

You think a high frequency Growatt 12000 ES (12kw) is durable enough to handle regular heavy inductive loads without needing repairs every year? 😭😭.
Abi just to go for transformer low frequency inverter?

brightk

Mrreed:
6kva inverter is fine
The 30kwh battery is fine too.
Based on your explanation, 5-6kwpanel should suffice

Thanks bro..
With full capacity load of 5000w, you still advice for a 6kva inverter?

cutefy:
You can go for a non hybrid HF inverter.

Are there non-hybrid HF inverter? Or you meant to write Low frequency inverter?

It'll amaze me to know there's a non-hybrid high freq inverter. Pls what brand is that?

xzynwa:
This ain't detailed enough for one to give a suggestion.

Answers to the following question will give a clearer information to what the recommended setup could look like.

Does the hospital plan to go completely offgrid?

Will all the loads be powered at the same time?

What are the critical loads and for how many hours would they be powered?

How many hours of grid power is available?

Would there be room for upgrade or addition of other appliances?

By the way, what about the 3 fridges/freezers at 1500w each still giving a total of 1500w?

Nna eh.
I ask WAEC question, you change am to JAMB question 😁😁🤣.

It'll only replace gen, meaning it's purpose is only to take up those hours when there's no nepa (let's say max 5 hours no nepa - but you can't trust nepa sha). They still intend to use nepa.
Forget the fridge watts, u can clearly see it's a mistake.
Assume that they'll be powered at same time.
Any where could be upgraded any time.

dollarnaira

I was thinking at least 30kwh battery.
Its inverter to use that's cracking me head.

You are a solar engineer and a hospital gives you this load capacity. 5910w.
Note the high power equipment in that load.

What materials do you suggest them to get for a good solar alternative power solution?

Battery kwh, panel kwh, low/high freq inverter? External charge controller?

Experts give ur suggestion.

Jefferyzz:
Yh. Sorry. It's 130v.

This felicity chargers tell you max vdc is 130vdc, but they never say what's the max current it can handle. It only states charging current (80a in this case) but that's different from the max current into it's input (or maybe I'm wrong).
I don't want to create strings of panels in parallel that will increase current and burn the charger.

Hope my poor English is understandable

BigDickProblems:
Taking a closer look at this image again, the funny thing is that the instruction on how to select your battery type and all that are boldly written on the right-hand side of the inverter. Damn!
😂😂😂😂😂

Lol. Too much garri made us not to see it
