Hello fellas, longest time.
Who remembers this my inverter room?
Well, this is what it looks like right now.

2x 8KW Deye Hybrid Inverters EU-Version.
4x 15KW Felicity LPBF48300 Battery Packs.
24x 600W Canadian Solar Panels.
10x 540W Felicity Solar Panels.
Plenty Automations.
ETC.

2 years in, still rocking with zero issues and no apparent reduction in capacity / holding its charge. Na wetin the cost go be now I no go wan hear.

litaninja:
So, here is the story of how I decided that I really don't need all my internal organs;
Remember a few months back when this strange company came on the radar but no one really had much information....and we still don't sha.








I tried to reach out to them via chat, but that didn't really give me the conviction that was needed. Also, put a call across to @Ojeysky which provided some feedback as well.

Well, since someone else had an interesting discussion with them, maybe I could have an interesting visit to them? Na so I enter motor, face the ends of Lagos (i.e. Epe Expressway), to the address provided on their website. The idea was maybe if I get there and actually see the thing in real life, then answers will be provided.

Arrived there after many hours of lagos traffic and discovered a small team taking a break from prepping materials for the manufacture / assembly of said battery units. So I got to discussing with them and got some info.

So they have 2 variants currently, 25.6v & 51.2v, Approx 5KWh and 10KWh respectively. The batteries are made up of 32650 LiFePo cells in the typical parallel and series arrangements we are probably familiar with already. Enclosures are made of steel, they have a couple of CNC machines and other tools to round off, finish and add aesthetics to the final product.
Still not too much by way of technical details, I was interested in the 25.6v variant, so, max charging current is 50Amps, Max Charging voltage is 28.8V.
There is a BMS and active balancer, but unfortunately no form of external communication to both. On pressing for the reasons behind this, reason such as, most average users are not really interested in communicating with a BMS (na una DIY people dey always wan chook and press something), warranty issues from improper configurations and misuse by the users and most importantly, the cost of communication capable BMS. The manufacturer is trying to keep the price down so it remains affordable (or at least as affordable as LiFePo can be sha).
There's a small LCD screen that displays the voltage and SOC though, so....

Anyways, after a couple of minutes with them, I felt convinced enough to take the plunge on behalf of the FTA Solar forum. But alas, there were NO UNITS in stock at that time. Due to the costs of scaling, logistics and general nigerian problems sha, they are only able to get a few units out per month. I was informed that they are working hard to try to scale up, get investments and generally increase production output but for now, dem dey manage as the whole Nigeria dey manage.

I promised to keep in touch and also got a promise that they'd try to squeeze a unit for me from the next batch.
This was about 3 weeks ago, anyways, last thursday I got a call from them, informing me that a 25.6v unit was available for the taking if i wanted.....na so i go do the surgery o.

Ladies and gentlemen....I now have a Pelton LiFePo battery, it does exist and it does look like its as advertised.
There's a 5-year warranty on the unit and there is the promise of after warranty repairs and support for a fee of course.
Pictures attached!

Call Me Oliver on 0814 063 4181. I once bought a unit from him. Ask him to send pictures so you can be sure that what he has is compatible with your fan quote author=ajabani4allah post=124267390]My Dc celling fan has been failing but it stopped working completely yesterday and during my testing I discovered it's the driver board that's faulty.

I remember vividly that you were using 16kw Deye hybrid Inverter, what happen that you are now using two units of 8kw?

Also, do you use separate CC to charge these 60kwh batteries or are you using the inbuit CC that came with the inverter?

NOTE: All these I have tested real time on a sunny day and I was good.

Grid is available but only turned on automatically by a contactor powered by a Photocell sensor on really cloudy days. So i could say that i am partially OFF-GRID.

All Water Heaters and 4ACs are connected as smart loads and configured to turn off once Battery SOC drops to 50% and no Solar Power.

Nice Question Bro.

This is because the 16KW I had was from JustStandout (A dealer in Lekki, Lagos), and I noticed that once I go Off-Grid the Inverter could not handle load above 12KW, I did everything I could but no avail. I contacted JustStandout, they could not help, they kept upgrading the inverter from one firmware to the other. I contacted Deye Support and they upgraded the Inverter to the Latest Firmware and the problem continued.

I disturbed Deye Support so much until they asked me to open up the inverter and send pictures of the PCBs inside the Inverter.
I did exactly so and I discovered that the power board inside the Inverter is of the 15KW US Version which is the SunSynk 15k-2P and has a UPS Backup load power of 12Kw Max. Which was why I could not go beyond 12Kw while Off-Grid.

The Inverter was sold to me as the 16KW EU Version which has UPS Backup Power of 16KW only to discover that the PCB is US version. It was clear to me that either JustStandout has scammed me or they got scammed by their supplier and they passed it on to me. Because I engaged them after this discovery and they sounded not to have any idea about these technicalities.

After weeks of words battle with them, I decided to place an Express Order from Deye for the 2units of 8KW EU Version which each has a UPS power of 8KW, because I didn't want to fall another victim to the 16KW Scam.

I received them and deployed them as shown in the picture and then I decided to ship out the 16KW to my house in the Village to be deployed later this year. Since I don't base there. At least no yet. hahahaha

As for the CC, I use the inbuilt MPPTs. Although I miss the inbuilt 3x 290A MPPTs of the 16KW because the 8KW has inbuilt 2x 190A MPPTs each. The 16KW starts sucking solar energy as early as 6am as is capable of guzzling everything that looks like energy from the panels, while the 8KW waits till around 9am at times to start picking up solar energy and cannot go beyond it's 190A capacity.

Congratulations brother.

This is the end goal.

I can't wait to be like you.

How many days of autonomy have you got?

Care to list all the automations? So I can copy?

I guess I have to read up on your past posts to understand your journey.

It seems that as your setup is up and functional you don't post so much these days but when you do post, it is gold

Nice one bro, it's a pitty most Nigerians always speaks grammar once money has changed hands. How can they say they don't know the capacity inside for a product like Deye/SunSync?

Well I like your monster machines as real money are spent on them.

Enjoy!

Clear case why I school myself in the technicalities of whatever I am get into.

This is a case study for why the end user should not allow himself to be bamboozled(hoodwinked) by the buzz words of the trade but understand technology at least good enough to know how things should work and be put together even if one has no intention of being the one actually putting it together.

Without such an understanding even his supplier could not help him.

This also explains why some of us go for known brand names.

It also shows that Deye is a good brand.

It also raises the issue of the grey market and what it can do to you. My friend here had to spend twice to achieve his goal. That was funds he could have earmarked for another project being redirected here to solve a problem he assumed he had already solved.

Nothing beats knowing what you want, being an informed client and going all out for it.

Well done brother.

It was a nice read

FEGEITOK:


You asked good questions

Yes oh bro, we ask to know and also pass the knowledge to those who which know.

I mean instant power coming from ur panels per hour or does it displays amp. If it does, aw many amps max av u seen on it b4? The charge controller is meant for 30a but can handle Abit higher. Say 35a. So if ur 2 200w does give u up 25a. U can add 1 more 200w. But if u get above 25a. Just change d controller.

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.

Quite a keen sight to spot these inconsistency, i have not experience these before, but then it is worth a trial to test these conditions out in the real world and i will cirle back with a feedback.

Depending on what got bad on the board, it can be fixed in Arena (Oshidi, Lagos). It's also possible you can get another board there. If you don't stay in Lagos, look for those whose specialty is repairing this type of fan colloquially called solar fan

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.

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

viperVIP:
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.

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?

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.

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

Disclaimer: I don't use Growatt.

But even if I turn off my inverter, it will power devices if it is connected to AC charging.

Since I am not using the inbuilt solar charge controller, I cannot speak for that one.

One thing I do know is that if AEDC seizes power when the inverter is switched off then every connected device will also power down, but if power is restored, even if the inverter is switched off, the devices will have power restored.
