Hey all hope Ure great

Recently added a 4.6KW PV to my 5kva inverter setup ( for 8 units of 580w jinko panels from fuoani)

I noticed that the PV only peaks 3,000w between 9am and 12 noon, after that time frame it just coasts around 1,000w and when load is added to it surges to 1900w max... By 3pm it drops to 800w

Please is the norm or might the PV array not have being optimally placed on the roof.

My setup consists of

5kva Growatt hybrid inverter

4 luminous 220ah tubular batteries

8 580w jinko monocrystalline solar panels

My average load during the day: 300w - 800w

One or two surges in load during the day to 2,000w for max time of 30 mins

Night time : 14 hrs of 500w

Take into account above scenario is off grid as there hasn't been electricity for 4 days

Looks to me like you are overcharging your batteries. Your batteries are 4X 220ah but In reality most of these 220Ah are 200Ah. Charging rate should be .2C = 40A, worst case 44A. 4OA x 48V = 1920W. You are charging at .3C.

Which app is this please?

Done and Dusted.

50KW Deye, 75KWp @ STC / 55KWp @ NOTC 61KWh Deye LiFePo4

It's 10am and this is how we are doing so far.

Same rate I bought my 625w Jinko panels.

twinskenny:


Both are pretty good I must! Am just used to the Canadian panels they are brand new

660watts cost is 168k as at that time

I totally understand you, when I upgraded my system in November last year I only had Inverter and battery which I installed in December and started using them.

I later discovered that I was burning my units charging the battery with grid, so I had channel all my funds to adding panels to the setup and finally became free.

jonescosmos:
Not a wise expenditure, you will spend more on the long run. When you install an inverter and battery, and light power goes of for 2 hours, traditionally you will switch over to inverter. Ok, you drain 5KWh from your battery before power is restored, your inverter will have to use your Units of 5KWh + Energy used in conversion and powering system components to dump back that 5KWh into the battery (a process we call recharging the battery) so you might end up using up to 7KWh energy to recharge your battery that you drained 5KWh from except you are not paying for the power supply you are getting.

So you see, you took less and paid more.

Solar is the way to go bro, If you ain't doing solar, don't waste your money. This is an advice you may not comprehend right away though.

Which is better buying single 625w or buying 2pcs 300w panels

Also anyone with experience with africell sunfit or sunshine panels

See what I'll suggest, this recommendation is coming on the heels of what I've experienced these past two years. I noticed the cheapo solar panels (Africell, Sunfit, Sunshine et al) may be cheap to get. But it comes at a cost some users may experience and not see. I noticed that after two or three years, some of the busbars (those silver coloured lines) that link the individual solar panels starts to burn. You may not see this as panels are probably on the roof, but you will notice the reduced production.

So in summary, instead of buying 1000w of Africell PV, you are better off buying 550w of Jinko, Original Canadian solar (had to put original as the fake are a dime a dozen), JA Solar, Yingli, etc.

In RE world, you usually get WHAT YOU PAY FOR. Pay for premium to avoid premium tears.

Same rate I bought my 625w Jinko panels.

Where did you got 625W jinko panel at that rate?

These question could help you better decide
1. Is the power meter or unmetered, i.e., if it is from NEPA or a serviced generator that turns on for just the four hours stated?
2. If your answer is yes to the latter, then you need to know how the loads in the office operate.
3. Armed with these answers, you can then decide which inverter you think would be of your preffered choice, cost range and can work with lithium easily.

A lithium battery would be the best I would recommend for you with an inverter with a high charging rate so you can more and faster within the four hour uptime of your available grid.

chidekings:
hello,i have a temporal office,nothing major.....and they have light 4hrs everyday,i want a simple inverter that can power the office when the light is off,would not want to start installing solar panels.

kind of a plaza lister that turns on for four hours daily......so which brand do you advise,and where can i buy the best ones.....thank you

I don later buy am on Monday as dem don reintroduce the 20k unlimited subscription. It's very good in my location. Only issue i noticed is the battery pack that comes with it doesn't last long. I realized it has two wifi output. One for 2.4ghz and 5ghz connection. I switched off the 5ghz connection but didn't notice much difference in battery drain. Is there any way to improve battery life?

Peterlove11:


You are right o....I tried to subscribe last week, only to discovered they've stopped the 20k unlimited subscription. Well, Na dem get customer to lose. My target is Mtn fibre, anytime they have a presence in my area, am jumping boat.

Your load is what would help tell what type of system you can use.

you can calculate the load through the link in my profile, it will help you know or estimate whats needed to be used and ensure to put your results here for more input. BTW it is best used from a computer browser.

What could be responsible for an inverter reading 0 watts when the sun in early morning sun. I noticed these fluctuations yesterday. It moves from 1.5kw to 500 and even to 100w and less. What could be the problem?

It probably has a slow MPPT tracking algorithm at work.

swagifted:
If i be paul enenche i for don put like 2 MW of solar panels untop the roof of this church (dunamis glory dome lugbe).... The amount he will save from diesel every sunday go de astronomical... Especially as na sunday wey sun de vex too.

Turn it to a mini grid and sell excess power when church isn't in full swing also.

I had the blessing to chat with a guy that has a phone charging shop he runs mainly off of solar and gen to compensate. In his worst days he makes 10k per day, zero maintenance cost when he is on solar.

He told me he can't even meet the demand as his chargers are always fully booked.

He said he doesn't want to expand just because he doesn't have the time to monitor a staff so he handles this one himself.

Xanderone:


Someone mentioned few posts back that appliances may stop working if put in storage for a long time without use. Is this why you made that statement
- (deform for lack of use)?

I have a Bluetooth energy meter that I retired/disconnected from the set up about 2 years ago and actually intended to sell it that time. I later put in storage. Few days ago, I tried to reconnect it and found out the screen backlight would not work. I even thought the monitor was bad, but I was able to shine light at some angle and realized it was the backlight. This is something working perfectly before it went into storage.

Pray tell, it this school of thought so valid?

I fear cos I have spare inverters (12v, 24v, 48v) in storage for use as back-up on days when repairs (God forbid) needs to be done on main units.

Where did you get that battery monitor from please?

mctfopt:


This is very true. My 8 x 18650 charger/analyser that I bought and never used have failed to work.

My Reolink 5MP camera I bought and kept for like 2 years (forgot I had it ) has gone bad too.

Same thing happened to my heart rate monitor I bought and never used. Remembered the other day I was doubting the rate my watch gave after an exercise The thing no longer works.

All these devices no longer works after about 3 years of it been left in their pack

Can anyone explain why this happens?

These days I'm now using every electronic I have. Don't want to be caught lacking again

If this is true...I don buy problem o. 😢

I have a couple of equipment I have not opened for like 2years. Maybe that's why manufacturers add that dessicant to their products in cartons to handle humidity.

Humidity may be the cankerworm.

Update on this review:
I recently installed 2 more of this CC : one for my use and one for a friend. Both CCs behaved different from previous installs.
1) They get much hotter than the older make. I suspect the fan speed. The new ones have fans that are very silent but not as efficient as older variants. Temps of the new ones got as high as 65°C despite the fan being on!
2) The temperature sensor gauges differently on the old and new variants ans could be off by almost 5-10 degree
3) On a good note, harvest seems better than the old variants
How do you know which one you got? The OLD variants had a light that constantly blinks in the fan recess in front.

Good observation. I noticed the new type also has an added menu option for calibrating the battery voltage.

Dam5reey:


Yes, boss that's how it should be! I do Sako installations in case +2348-132394478

Neat installation.

On going:

50KW Deye + 61.4KWh LiFePo4 + 74KWp PV

Which states do you cover? Your installation is neat. Can we talk please? Maybe we can do biz.

I wish to get a new Starplus battery 220aH tubular. Is it a good buy??

Not a good buy.

Better off buy other lead acid brand like Luminous, Genius, Eastman, etc.Failure rate of Starplus batteries is very high.

Sorry but what do you mean by failure rate pls?

EPOMA:


I don't even know what to type here . I have bought 2 batteries from Valto and they work well till dat since 2 years ago, Buying from Valto which is a coupled batteries , I gave room for any sort of small issues . His batteries are good and new better than felicity. I would rather get batteries off Valto and learn how to couple them than spend 3.5 million for all these big names , I guess because I am a technical person.

Valto is a trader in my terms and I don't also expect customer services from him like a big company .

My conclusion is simple , Not because your inverter went off today or the battery has some issues make Valto a bad dealer . He is a good honest seller. I am looking for money to get 2 more batteries from him .

Sorry for your inconvenience sha . Right now I have my inverter with Victron for over a month , I have been chasing them but no response. Lets jus try and manage ourselves please

And felicity won't do this...be like we suppose apologize to them for the bad mouthing of cheap products and low quality.

HeavenlyBang:
We don finally enter rainy season proper.

Na trenches be this for solar walahi. My setup isn't able to add more than 50% charge to my 4KWH battery in a day for the past few days, especially since I'm off-grid and there's rarely NEPA light anyway.

If this persists, I'll need to add an extra panel to my string.

odimbannamdi:


Are you sure you are a Nigerian? When I was younger, I remember a period we didn't have light in my former area for 1 full year!

My neighbour gave birth to her baby girl around this period, so she never heard the word "Up Nepa". The day the light issue was resolved and electricity was restored, the little girl nearly had an heart attack due to the chants of "Up Nepa" that filled the air that unforgettable evening! Street scatter! Everybody was dancing on the street! It was like a dream and miracle put together

Years later, electricity is still a big deal and still feels like something extraordinary. I thank God for solar energy. The only connection I have with Nepa and gen now is to pump water occasionally.

I think I remember that incident. The celebration be like say Nigeria win world cup. 😂 😂
