@Justice629 I'm glad you could confirm that as well.
@coldcandy would you just leave an inverter in on position for 12hours when nobody needs power from it, I mean for no good reason, you just want to waste idle energy for 12hours ?
@Dam5reey Ofcourse to save energy, who goes green with the aim of wasting energy? If you switch off the output breaker, you have idle energy consumption wasting away, which isn't a smart thing to do.

tsiriman:
I've also been wondering why inverter needs to be switched off

NO, it does not need to be ON for the pv to charge.
it only needs to be ON for the inverter to produce output power.

coldcandy:
I am just wondering why one would put the inverter in OFF position.
Is it not supposed to be ON to work?

FINAL EPISODE

Old man's printing press was burgled last month, his solar and electrical cables were carted away. So I went to replace them a week after, and when I got done, I figured out PV wasn't charging when I switched on the battery disconnect, only to put on the inverter, and PV started charging. In other to ascertain the issue is real, I put off the inverter, trip off the PV breaker, then disconnect battery.

Few mins later, I reconnected the battery, reconnected PV breaker while inverter is in off position, still inverter will not charge until I put it ON and OFF back, then it started charging.

I interrogated the staff and they confirmed they have observed the issue before now, for example on Sundays when no one is in the office and it's expected to meet a fully charged battery on work resumption on Monday morning, but they come back to meet a low battery just as they left it on Saturday closing hour.

I wrote to Sygnite on this issue with video evidences, this time I spoke to their chief engineer who agreed that the MPPT Board is faulty this time around and in an attempt to claim warranty replacement, he said 2 years has passed from date of purchase hence out of warranty. Till this moment, I didn't bother asking for the price of a replacement board because I am furious athow they are cashing out on people with a poor product.

They put the inverter off every night and put it back on in the morning,
had it mean it runs 247, then they wouldn't figure out the issue.

I could recall in one of my chats with one of their engineers, he suggested maybe temperature is the culprit and I made him realised all these inverters are not on the same premises and conditions, they are all installed in well ventilated environments, I can guarantee that, except the temperature issue is from the inverter design itself which I do not think is happening. Also suggested voltage issues, I have never gotten too close to 400v in all my setup when i can still do 420v pv in put, it has always been between 250v to 380v and my systems have SPDs in place in case of surge as well.

Even if I pay for a replacement board now, these systems are not up to 2 years. So let's say in another 2 years, the MPPT board can be gone again for unknown reasons and I will have to pay for another board?

GROWATT PALAVA, EPISODE 2

3 of the said inverters were installed on different premises with lithium batteries. I have no reason to return to 2 of the sites as the systems are functioning properly according to the clients, but the third site, just after 3 months of installation, the client himself complained about the said issue above, noticed by himself. If he ran his battery to low state at night, he expects the PV to wake the inverter in the morning due to its batteryless feature, it wouldn't, yet it used to when it was just installed.

Fast forward to the 3 units I intend to install on my site, I ended up installing just 2 due to budget and the third one was installed in my dad's office, a large format printing press. The 2 I installed on my site, I observed after just about 1 month installation, that I barely use the second inverter in parallel except I have to run my power tools, so I only leave 1 inverter ON 247 and the other inverter is serving CHARGING purpose alone from it's attached solar array. Then I observed when it's morning, this second inverter that is OFF will not charge from solar, only the one that is ON and working 247 will charge, so I will have to switch the second one ON & OFF, for the charging to start. This I do every morning till I got fed up and wrote to Sygnite engineers to lodge complaints, we dragged this over and over for weeks, they kept on saying nothing is wrong with the systems despite video evidences.

Then from google search to growatt website, I located Xing Yang, the sales manager for Growatt Africa I suppose, he referred me to another dude Joel, this communication went on back & forth till Xing asked me one afternoon that he's in Nigeria if he could visit me, but on finding out that I don't live on the Lagos Island, he suggested a video call to open one of the inverters and use my multimeter to check a spot there on the MPPT board, which didn't give any reading, then he concluded I needed a MPPT board replacement, so I applied for 3 MPPT board replacement on warranty and it was sent directly from China to me after 5 days through FedEx, since Sygnite refused to accept that it's faulty. I do not know what kind of engineers they have in their company.

I replaced the 3 MPPT boards myself in my 2 inverters and 1 for the decommissioned inverter previously, then all the features were restored to factory features. All 3 working well after. Last occurrence was the single inverter I installed in my dad's printing press.

End of epicosde 2... last episode coming shortly, I'm not too good at writing long epistles like this but I might be helping someone.

DON'T BUY GROWATT SPF 5000 ES WITHOUT READING THIS.

PS:: I am writing this not to defame the brand, but to read from others on their experience or maybe they just never find out.

I discovered growatt inverter on youtube channel of David Poz and further research on it led me to nairaland where I read from Olopan and his good experience on them. So I fell in love with the ES model and bought my first 2 inverters (SPF 5000ES) to be installed for a client as an upgrade from his previous nightmare YOHAKO, the 2 inverters were installed in parallel, after 7 months, client didn't find a use for 10kw inverter, so one was traded for more solar panels.

NOW, here was my observation.

When the decommissioned inverter was installed at another client's premises, the inverter will not come on with PV alone as designed, so I thought maybe it's from my installation, but i knew 100% that my installation is OK with no issues. For the inverter to work, it must be connected to battery, switched to ON position, then you will see it charging via PV. But if it's connected to battery and in OFF position, the PV will not charge your battery until you put it on. You may now put it back to OFF position when the charging starts, but if you switch off the pv breaker at this point and switch it on again, it won't charge until the inverter is back to the ON position.

The client didn't know this and thank GOD he has enough battery bank to take him 24hours, so he might never witness this issue.

While feeling unsatisfied and thinking a damage has happened to the inverter, I went back to the previous client that traded it out, on a maintenance note, I tried the system with same sequence, it wouldn't charge unless I follow the sequence listed up here. so they both suffer the same challenge. While google searching and thinking of a way forward, I proceed to buying 6 units of the Growatt model again, for 5kw installations in 3 premises and 15kw parallel installation in my personal site under construction as at that moment.

I will write further on how those ones went tonight.

And that's why I'm not applying directly from outside UK. I have had few offers in the past who are ready to employ but you must be in the UK and yes! They have COS to issue so you can convert.

Also, have you considered an apprenticeship program in the UK before?

Mindlog:
Under which occupation code is solar energy expertise fall in the UK's skilled worker visa shortage occupations?

COS alone!

Thanks your response, how far with the process? Have you migrated now? And the 12m,what's it for?

While in the UK, the person can apply as a care worker, but from outside UK, I do not think it's possible, I was in same shoe, my wife couldn't be the MA because she has just NCE, so I had to shoulder it, knowing fully well that within 1 year I can write some exams to get my license as a certified solar energy expert, then switch to my main profession by securing a new COS, not minding the 12m already paid now. It's the cost of greatness afterall

Allschoolsinfo:
Good day @all,
Please can someone with NCE apply as main applicant for care worker?

I learnt it's better the wife be the MA and husband dependant so as to enable take up more jobs.

NO! For some, it takes a week after to get the brp mail, so no issues.

Clevo:
Got a mail to pick up my travel document. No BRP mail yet. Should I be worried?

TLS Ikeja didn't open today.
I just wasted my time and money, heading back to my state now in case you're planning to pick up there today.

What if!!! You give a response stating the father is out of job for a while and won't be able to take care of the day to day finance of the child Hence the need to come with you.

[quote author=Molajim post=124116289][/quote]

No, you're to wait till Friday.

Olaide1295:
Today and tomorrow are holidays in Nigeria. Will one be able to pickup?
I also got a mail to pickup today.

Congratulations
please how long did it take
Give us timeline.

Thank you.

Nwokiwu90:
congrats

Finally...

As long as the father's name on the birth certificate is clearly spelt out. Then no issues.

Mykelpato:
What of the situation whereby your child had your wife’s surname on her birth certificate and it was used to process the child’s passport, will that cause any issue at the home office via visa decision?

Technically this is right. But the instances I have seen, they don't have children yet, so it's hard to say but you can apply for another birth certificate to reflect that changes in the worst case

Peniel13:
Thanks for the response. I'm just confused because the immigration officer doing my baby's passport said my surname on my passport has to align with my surname on my baby's birth certificate. I bear my husband's surname on my baby's birth certificate.

No, you can be married and not change your name on your passport. I have friends who have applied and are in the UK now with their wives making use of their maiden name on passport because of the rigours of going to Abuja to change name on their passport. So you're good to go

Peniel13:
Hello house. My passport carries my maiden name because I got it before marriage but I just had a baby and my baby's birth certificate carries my husband's surname in the mother's space. I have done change of name publication and affidavit and I have my marriage certificate. Pls I want to know if it can pose a problem for me during visa application.

Ok thank you. I just left the TLS Ikeja for submission now.

giselle237:
no need

Hello house, please help!
I did my TB test in january and I am just filing for my visa application now, my home address has since changed.
Do i need to contact Qlife to change my home address on the certificate and have a reissue or no problem about that?

House gurus pls help...
My afripower 1kv inverter stopped charging wit nepa/phcn for a few weeks now. Suspected it was the fuse in the input socket that was faulty but didn't hurrily replace as I av a suoer external charger which i use to charge my battery. The suoer charger fan however failed some days back and it gets extremely hot, i had to open it up and only use it when i get home so i can use an external fan while its working. Fixed the inverter socket fuse yesterday and when i plugged it to charge wit nepa, inverter went off for a few seconds, had to switch of the inverter and change over from inverter to mains and it started charging. However ths morning when phcn went off, I changed over to the inverter while it was plugged to the mains, there was a backflow wit sparks in the inverter and the inverter died wit the screen blank and no output. However 10mins after, it came on again and was working. Tried plugging another appliance to the same charging spot which didnt come on and nothing happened with the inverter. Is it possible the new fuse caused a back feed?
Can anyone help me wit suoer internal fan in Abeokuta or waybill it or what alternative do i have as the rechargeable fan i use doesnt come on automatically so its only when i am home i am able to use it?

.

Thanks for your input.
It is only dense for you to send an item with the mind of "if you like collect am, if you like no collect am"

Peterlove11:
From the few times have transacted with justcallmenuel. I can say boldly the experience has been good. And I can safely recommend him. Based on your side of the story, I think it's an issue of understanding, since Abeokuta park is no longer available, i think he is handicap. The two of you are egbon, and I believe you can both find away around it.
Talk to him I believe you can find a mutual ground for the delivery price.

Will I be the one to pay delivery fee for you all the time?
How many times have you paid delivery for me, cos you sounded as if you're doing free bonanza on my orders?

I only sent growatt to you twice young man and I never said I wouldn't be responsible for the logistics, you said the first one you have a product going that way, so you'll add up.

Second one, you said i'll be responsible and i ask for the price, you said it and I paid, If you did pay 12k, you will say it, i know you.

Also, wrapping nylon 4k to wrap my inverter, are you kidding me?
oga, i get picture o o ... !!!
Anything wey you like, me don ex you sha...

Hello house, I met @justcallmenuel on this platform and I have made purchases from him numerous times but it's high time I stopped dealing with him. He lacks understanding and does things his own way without consideration for how the customer feels.

I need to replace a battery for a client, out of 4 quanta batteries, 1 gave up and it's giving the client (a cancer hospital) so much worries, client wants the battery bought and replaced today in other to save his patients. I chatted Nuel up last night and asked if he could make it possible which he guaranteed that I will get it in Abeokuta by 1pm at worst, i told him 12noon will be better and we agreed. I reached out to my ibadan vendor and he confirmed he has in stock too, but just because of the relationship with Nuel, i decided to buy from him.

Only for him to tell me this morning that the park that sends to Abeokuta there no longer exists, and if they have to take to iyana ipaja, i have to pay #10,000 for the delivery to the park, excluding what the driver will still charge to deliver to Abeokuta, just a single 200ah quanta battery. I told him I'll rather have a refund if you can't keep your end of the bargaining or you do something about the delivery cost, this mindless Nuel told me he can't refund, he bought it from someone too and went ahead and send it via the haulage that won't deliver until tomorrow, this is after picking up from my ibadan vendor.

My fault was to think I'm keeping a relationship with him by coming back to buy, but right now I'm blocking him off totally.
Just know that before you start threading this path, @kiekie1 was once relevant like you in this forum.
No peace for you @justcallmenuel

Check behind the inverter, you should find a breaker controlling the grid input, it has tripped and you should switch it back on.

Alienwarfare:
My inverter started showing this and it is no longer changing from the grid

A little secret here, an engineer in this same company once told me they have a series when loaded beyond 50% of its capacity, would result in overloading.

So I ran for my life

vta2008:
Before I bought mine from PRAG, I did reverse Google image search and saw that omo all of these stabilizers and most inverters dey Alibaba. They just slap their names on the product and call it a day.

Even the manuals tell everything. Very poor English as though they couldn't pay a Chinese man with proper English skills to do the translation.

Quick question: does your dunamis come with a user manual? Maybe you overloaded the stabilizer and this wahala ensued. They never disclose on the sales page but on the manual you'd see that these big stabilizers can only carry load at a certain input voltage. The lower the input voltage, the lower the amount of load you can put on the stabilizer

You are right.
I tilted it to the extent as if I was guarding the sun rays from escaping that's when I was able to get that 101 or so, without tilting it's worse, about 65-90.

So I am very sure of the figures, that's the best the panel could produce.

mangolpupa:
Bros before you confirm you're disappointment with the panel. Can you ensure

1) it's not "backing" the sun and is on an axis that harness sunrise and sunset in your location.

2) if you already have no 1 sorted. Please consider optimising the tilt angle of your panels. This often overlooked factor can mean the difference between generating 100WH and 130WH in the same position.

Try this first before concluding (this is assuming you've not tried it).

All the best my oga.
