I've done this before and it ended in tears. I did parallel Longi 450W with 11.60A Isc. The Growatt will be working fine until sun hears it's peak and it sees 22A and then enters into error mode and shut down after 3 minutes or so

tag me pls when you have a solution.

HeavenlyBang:


Power is power, regardless of voltage/current split.

My inverter is limited to 13A, my PVs max out at 11.5A, but I don't think I've ever gotten more than 9A in the real world.

Still I run a 1 HP inverter AC in the afternoon comfortably without the inverter drawing any power from my battery.

Power is not power when it comes to inductive load. It's because you're using inverter AC. You can go lookup on batteryless setup on YouTube, you will see AC doesn't want to power with 10A Pv and 400V until the guy had to add another array to increase current.

mctfopt:


Those two panels you mentioned have Isc of more than 11A each which will exceed the yeye 5000ES Growatt's maximum PV input current of 22A

11A panel cannot give u 11A consider losses. Just do the two parallel end up getting near 18 to 19A. U guys that are doing this high voltage series should give us feedback with inductive loads...how many Ac's were they able to power without battery during the day with 11 to 13A PV or more.

2 Million Naira, 24V 3KVA Inverter, 4X 410W panels, 5KWH LFP pack. all Sako
check the previous post for Sako details, prices are not fixed.

Fair enough. Thank you.

The solar gurus in the house. What's the Max. Watts you have had dissipated by your 40a & 60a pwm controller during setup...not theory oo! Real life experiences?

Dam5reey:


Hybrids are here to stay and have stood the test of time already. why are people still contemplating?
Hybrid gives you an Inverter, Charger, and MPPT, cheaper than any standalone.

example with 250K. you can have
a 3kva inverter with 60A charger,
80A MPPT, go and price stand-alone equivalent.

Hybrid allows you to customize slightly when grid charge, how much grid charge, when Solarcharge, Only Solar charge during the day and Grid charge in the night, etc. with standalone, you need to have good know-how and other tools to achieve these.

Sounds good. Pls how much did you get your Sako and the panels. Can you give us a breakdown of the cost implication of your setup. Are you using Lithium of Lead.

kwende:
Experts in the house, kindly suggest what complete solar solution I can get with the following

Budget: 5 million naira

Prefered Battery: lifepo4 lithium battery

Location: Lekki

Estate generator provides 12 hours of power per day

Thanks a lot....appreciated

Depends on your load. Mostly 5 to 6kw inverter.

Next question should be choosing between transformer based inverter or chopper based? Cause 5M no b small money, @bassdow @bigbrovar and other experts make una pls come give expert advice. Anyone with experience with transformerless using iron and AC for like 2yrs no issues....

Swagifted:
omo if our export no overshadow our imports nothing wey fit happen o.... And if the general public no MASSIVELY consume goods and services that are made in Nigeria nothing better go still come out... The story long but that's for another day. DSTV don increase money still no Nigerian competitor.. It is well.
......….................

I got the mail and I was like what grin grin grin

People are now porting to MetroDigital SLTV

It's well with us

..........................

@Swaggifted, you know the problem no be about import as some ppl dey shout import import. Do you know the rate of China import and export na almost the same thing. No person can become an island of it's own. How will person say him no need help from other people and nations. God wey create us in nations and varieties, languages know the reason why. So we can all depend on each other.

But here we are some people blaming imports. The problem we get for Nigeria na 'primitive accumulation of wealth' one person go one loot a whole nation dry & 'vested interest'. For every problem there are ppl benefiting.

Them get people that will fight to death make import dey sniffled as e dey now...cause them dey cash out.

A perfect economy should be an economy that encourages competition in markets not stifle it. If u feel people are patronising imports then improve your home grown solutions not block it. Archaic policies.

Make I know bore una sha, cause this one na solar thread not politics. But Buhari did us dirty & Tinubu just want to be copying this White guys style of capitalism whereby the nation isn't ripe for such policies. In all, I put the blame on Buhari!

Nigeria get long term fix and short term fix.

As a matter of urgency( short term fix): 1. open the border like LovePeddler all those products dey ban dey should unban them cause some ppl be cashing out from the restriction of imports.
2. We should be able to purchase dollar directly from bank not proxy
3. Bring back the fuel subsidy & subsidies in other sectors as well.
4. Export should be encouraged cause exporters dey complain also say dem dey face wahala.
5. Food inflation, they should fight the bandits cause many farmers are displaced( insecurity). A total ban on miners cause dem get northern cabals cashing out from it thereby constituting insecurities in some pivotal agri-states like Niger, Benue etc. Like anywhere there's mining there's insecurity. All these things started when Buhari enter office.

If them do this everything go normal again at least for a while.

bassdow:

you know there are people who don't know that something as little as 1-amps from a 200Volts source, is much deadlier than 12-amps from a 5Volts source.

True talk. Because with proliferation of solar like this, especially all this high V PV's installations for residential homes, he good make installers and users as well know the dangers. Proper cabling etc, to avoid story that touch

QuoteJust1nce:


But the chances of high current fires would depends on both you, the installer, the wires, the breakers, the batteries, etc. Too much to risk. You're better off pitching sides with low current high voltage than high current low voltage. These are my opinions. Never been shocked by DC but A/C, one too many times. Stay safe.

🤞🤞🤞

Dam5reey:


You shouldn't worry about high voltage if you already use 220V comfortably, you plug in devices without even thinking twice, your High Voc has MC4 connections, and it's only at a spot in your own which must be treated with Caution.

👍👍👍

isangjohnson:

I may not really understand what you mean by "an average hybrids require large panel arrays to power loads and charge at the same time" but I've installed 1.5kw 12v hybrid inverter 150v 80a with 2 pcs of 580w Longi pv and 280ah 12v Lfp battery for someone. He powered his 140w freezer during the day and still get the battery to float before 1pm depending on how deep the battery was discharged at night.
I'm expecting 1kw 12v and 1.5kw 12v high frequency hybrid inverter next month and I'll still test the charging system as well.
The issue you experienced may have caused by the configuration of that charging system by the company.

Mind sharing the product. And array config. Total voc

Drgreatone:

Unless he's getting a high quality hybrid inverter, he's better off having individual components. From my experience, the average hybrids require large panel arrays to power loads and charge at the same time. Use a small array and u wud be dependent on grid for optimal charging unless u add an external charge controller

that hybrid high pv sef dey fear me! Like whooping 500V to 400V for person house.

Which is even more severe in electrocution between a 220ac and 400v DC.

And another thing have been thinking about, betwn a 200v/20A and a 400v/10A source which would cause more damage?

I still feel for homes make PV array dey around 100 to 150 range for safety. Just my thought sha!

saint2ace:


You have a Hybrid with a high voltage MPPT CC, the optimal functional voc for such inverters is from 150v to 230v, less than this is workable but not optimal. So an external CC with a VOC capped at 150v should serve you better. Just me thinking aloud

Great contribution. Another angle @Drgreatone; keep us posted if you find a solution.

Mavor:
Ok so purely charged by solar. Does it suffer recharging during the rainy season when sunlight is less? Where can I find the complete BoQ online plus price? How to purchase? Is the battery Lithium ion or Lithium Iron Phosphate and what is the battery capacity? Thank you for your kind assistance.

Don't worry I have sent the creators this link. Let them come and defend their products themselves. They will reply u. I just go the product say 6 months or thereabout now, haven't used it for the raining season.

Mavor:
Thank you but what is the complete pricing today for the whole setup? I find it strange that they didn't include this info or a breakdown of the setup on their site. Also where to purchase in Lagos.

Let me tag the creators of the box to this thread, make e com answer question.

Mavor:
Into wallsocket ke or into your switchboard? Abeg I dey confused as I be JJC.

yeah, you can put a power source into your wall socket at home. Just ensure their is no mains(grid). My area no Nepa. NEPA is disconnected.

Drgreatone:

Combining in parallel defeats the purpose (I'd av to climb the roof again to reconfigure) and requires bigger wires. Using a 6mm wire already
Its a 300w panel with abt 9a of current though max i av gotten is 4.
Already mentioned its a 2kva12v hybrid inverter with mppt volt of 30-400vdc. Just feel it doesnt charge well wit solar which is why I'm considering getting a seperate mppt charger. Plan B is to add another panel and see if there's any change.

bro that current is small. Don't waste your money on cc. Just add one more panel. Take the pain to do 2 series// 2 parallel ( 37*2volts and 9*2amps). If not that sometimes the sun might not be strong, and the 37v panel might not dissipate enough volts to charge the 12v..i'd have advice going all parallel on the four panels so you can have 9*4 amps.

@mavor

In my area no light for like a year. So I didn't even stress myself, I just connected the output of the box directly into the wallsocket. Powers ox fan like mad, 2 laptops, my redmi phone 70watts chargeer, TV...lighting points, I just need to add two more panels or 3 so I can have enough current to use while the li battery charge, cause the battery dey deplete on load, meaning not enough array. To think I spent 300k for the setup then.

Mavor:
Thanks but the powerbox site has nothing on the product or cost. Very weird site homepage. Please advise. This looks like the stop-gap solution I am looking for. I appreciate your help. Also can you please share pics of your own setup.

ok let me take some pix..very simple setup. Two 150w felicity 12V panels on the roof facing south ward connected in parallel to the powerbox. I didn't even bother to put any breaker. A 1kwh li battery so they say. We all know u can't get 1kw on a 1kw inverter.

Drgreatone:
Pls need advice. I have 3 300w panels connected in series to my 12v hybrid inverter but i feel it doesn't charge effectively so thinking of getting the powmr 60a mppt to charge my battery better.
Panel's Voc and Vsc are 37 and 32v respectively. Seeing the upper limit of the mppt for 12v as 80v(mppt voc is 160v), can I ignore it and still leave it in series or what's the best panel combination.

why not connect in parallel to get more current. And you haven't told us the current that each of the panel generate. A 37V panel should be able to charge a 12v system. U need to give more details of inverter specs and also the current of the panel. And hope Ur array are facing south or southwest. Or do two panels in parallel(to boost current)+ 1 panel in series...I forgot sef, still the same shit, the solar array will go with the least current..so maybe, just parallel everything.

Mavor:
I clearly stated that my budget for a stopgap system is 600k. In a second post I can push to 800k. I just need something to manage till I buy the 5kw inverter/10kwh battery in sept/oct. I know I am a novice but he can maturedly advise me about price instead of being dismissive because of my proposed budget.

Check my previous post. I'm currently using 1KW system. But you have to add like 2 to 3 more panels 45k*3 (12v/150watts) again to enjoy cause I'm on two panels. So far has been great.

adibo:


Good morning, if I buy a hybrid inverter, I can use it without any battery? If yes, can you please explain more how it works. How long can it last during the day?

Yes. From 8 to 6pm but advisable to get at least a small battery backup, say 1kwh.

But you have to over panel it. Cause most of the energy would be coming from the panel. Like if you have a 3.5kwh inverter & Ur load is 1kwh, you could use between a 1.5-2kwh array or more if your budget can allow. Advisable to get the datasheet of the hybrid inverter so you know how you would properly configure it with the solar- taking input voltage and current & power--- series connection.

Second, you put a DC breaker btwn the array and inverter and transient protector between the inverter and NEPA( u know how NEPA light dey fluctuate) or don't even use Nepa at all and earthening of the inverter or a thunder arrestor on the array.

E.g. If inverter can take array of 500V input, current say 80A and you have each of your array can dissipate 42V, 13A. You have a load of 2Kw. You can use a 4 to 6kw array by connecting your array in series to give like 420v at 13A around 5kw in a perfect scenario ignoring loses. And use a DC breaker that can take 500V and the current.

That sms inverter price u quoted, when did u cost it? It was 440k abt 2 weeks ago.
The 850k might just be barely okay for a 12v solar system with todays market price

Wahala! was around 300+ last time someone installed.

jasp12:


Good day,
Pls can you advice or give me a rough estimate to set up a solar inverter system ... budget is 850k

Why not go for a 3.5KW SMS sunmate hybrid inverter. Probably with a 2Kwh battery bank. And and let's say a 1.5KW or 2Kw solar array. Might be best value for money as you can expand.

Other perks: DC breaker, transient protector.

The hybrid inverter comes with it's cc. Cost around 350K.

Like play like play 850 don go, except prolly u go do without battery...just dey flex am for day time. Keep in mind, it is better to do DIY that you can easily expand on without selling parts.

Open to corrections.

All the best.
