Lets start from the top

1. You use a tier 4 panel-why call it that is beyond me but you have your reasons

But you should expect the four panels to work like 2 good panels with each contributing 25% of its nameplate

2. Charge controller and cable looks just fine, highest those cable with do is get lukewarm in temp.

3. All you have done looks okay, panel to roof space is okay as long as you not slapping them panels to the roof

My advice, don't waste money, if you very sure your panel is clean, then know that your panels are the bad eggs ... I have similar setup one time but with 2 x 150W and highest from it is 17A

So manage it or upgrade, getting MPPT may give you a little gain but you didn't mention your battery.

I leave this to others to take up from here

Solarrookie:
I recently moved into a remote area and got some tier 4 600 watts mono panels for myself (150 x 4) for a 12 volts setup. I also got a 50 amps PWM charge controller and 10m cable dual core cable.

What inverter do you use?

I would have recommended pylontech Or BYD if you can afford it.... Communication and seamless integration is so much easier with them

adrusa:
Hello, I need some pre-packaged 48v lithium batteries for my office. Shouldn't be too expensive. Preferably Felicity, but I will consider other ones. Please quote me if you have.

This is mostly a Grid-tie kinda solution

And it's tagged commercial and industrial solar solution or C&I

It works on principle of energy usage reduction.
If grid is available and solar inputs its power grid consumption reduces likewise generator fuel consumption all controlled through an intelligent controller that ensure generator works above minimum 30% requirement.

It's a day time usage arrangement,

FYI- it's batteryless and for less than 1MW it's not up to a billion as expressed in an earlier comment.

We offer this solution to companies too.

All nah foreign investors moni.
You can look up PPA - power purchase agreements

So I wonder, is this also gonna power their heavy duty appliances (all those bottling machines and conveyor belts that use energy hogging three-phase AC motors) or will that be only available for use during sun-hours? I don't know if their assembled battery pack will allow that much demands.

Good morning everyone, Trust we all had a splendid weekend

To put in a word on the ongoing authenticity of Canadian posted earlier.

I have to be honest with some fact .... Based on evidence of that sticker

This i conclude as I have being in market to select things in person before

1. The displayed Canadian panel is doubtful
The edges are not consistent with its cut also the air pockets are dead give away.

Twice have I being nearly push to buy such unauthentic products

2. He said something of truth though, they bring in dirt cheap panels of a particular brand .... Looks good on the outside but best to shieve through your product yourself to prevent getting those with corroded MC4 connector.

With these I'd say buyer should proceed with caution and to ensure everyone happiness - buyer and seller .... See what you buying ...

Know this " if your gut says it's not real, then it's not"

Stay safe and have a wonderful week ahead.

You welcome

davidolarewaju2:
Thank you sir

In other to get contribution from others and me here.

Kindly provide

1. The critical loads or appliances Iisted below their power consumption in wattage [W] or noting the nameplate sticker on product

2. Preferred hours during the day and night you want each appliance above to work for you [be well detailed here]

E.g fridge -100W
4 hours in day usage and 3 hours of night usage et.cetera

3. Lastly how many hours of Grid do you have, in case you plan on using it together

Biafran4life:

Good day house
I want to buy panels (300w), which solar panels brands should I go for?

Thank you

The name of the fish you caught is a "snakehead"
It has sharp teeth and fairly tough scales ... I caught mine in osogbo couple of years back and its a fresh water fish

Still looking to hunt for it in the future ...the meat is tough and white ..such a delight.

Light78:
I was walking around my compound yesterday, and I saw a fish jumped out of the marsh to a drier side of the compound. It was struggling to swim back into the marsh, but I caught it with a basket.

What is the name of this fish?

Being hearing of older fish with high mecury content .... But if it's a long time chow and not a regular one ... They should be fine

So got a medium action rod mid-2017 shipped from abroad and it was a blast ... Being enjoying every bits of the adventure with it

Four different states: osun, oyo, lagos, kwara

Six different fishing spot: Ede water reservoir, river at Ogo-oluwa osogbo[Google map to find], asa river extension, Agba dam both in ilorin, Lagos beach, lagos jetty.

While at the Lagos beach, used my medium action rod and caught one decent grouper, and used a bigger bait to catch bigger fish - Big mistake of the day .... Caught a big fish alright, but that sucker peeled my line and got me stuck in the rock.... Thinking I can tire it out .... Broke my rod manuevring around it.

Nice one mate

I never had that kinda luxury where I grew up... I literally grew learning the family business but the adrenalin rush and patience with tactical thinking aroused my interest in fishing.

Great experience i have to say

Victor8st:
As I'm a fisherman from the childhood (kidding), I remember going with my father always, and to be honest, I hated so much that thing while I was a kid. No way my mother always told me that when I will grow up I will start loving some things that I've hated while I was a kid. Some years ago I had some free time, and I was like, I should give it a try, as a lot of my friends were fishing. Furthermore, thenatureinsider.com has an interesting article for the beginners, who wants can check it out, it was very useful for me. So the thing is that a while ago I was in California at the Crowley Lake, the first time there. I can brag myself, I caught about 8 Trouts weighing each from 15 to 20 lbs.

Hi

For your 1st option: 1200W minimum for 40A charge controller @24V

For option 2: 2400W minimum for a 40A, 50A charge controller @48V

MPPT is better for you here

Victron

Epever

Kartel

Felicity

The last two have base within the country so warranty of up to a year is possible

Victron offer 5 years warranty on their products ... Ensure to buy from accredited dealers to be safe

adiosgracias:
Please I need advise on the type or AH of solar charger for :
2x200ah battery
4x200ah batery

Please be specific with brand name

Glad to be of help brother.

The way lithium behaves on the growatt is incredible and different from Lead based batteries, the battery stops taking charge all together.

I believe it's was originally based on Expert variants but they did in house designed and changed things to suit them ....as no float bug or whatsoever for now .... All installation done with growatt is performing brilliantly with no issue So far.

IYGEAL:
So I had my 8s1p array changed to 4s2p and acquired a 24V 3KVA Growatt hybrid inverter through @Olopan of Rendezvous Solar, to replace my SMKSOLAR. He got it for me at a price less than those I got elsewhere, and the delivery was swift.

Growatt is notably faster in charging (maybe because it doesn't require minimum input voltage of 120v from pv).




I set bulk voltage to 27.6 and float at 27.
During charging, it goes up to 27.8, sometimes 28 volts but never above that. When it gets full, the inverter basically stops taking in any power whatsoever. At this point, the pv input reads zero; meter on the battery reads zero amps. These only change when I increase load significantly.

The inverter meanwhile, apparently consumes only little power and this is significant for someone like me with small battery bank. I attempted running my 75W fridge overnight when I was using smksolar, the inverter tripped off before 2am. I have run the same fridge twice overnight and the lowest reading on Growatt is 26.2V.

On the other hand, the load reading on the growatt 24v 3kva inverter is false and the fan, although not too noisy, doesn't stop. Also, the inverter has an app which I have not succeeded in activating.

Is there a separate device with which one can read the input and output parameters?

I'm curious, is Growatt Axpert variant? I think if it is, it's arguably better than the other variants.

Happy new month and a productive week ahead to you all. Remember being diligent brings outstanding result

#mondayinspiration #rendezvoussolar

The effect can't really be noticed instantly sometimes

Except one goes head on to compare both in the same location and area just like victron did in Romania

From my personal experience I have discovered tier 1 trump over tier 2 in

1. Daily harvest and yearly harvest. Even if they are both the same capacity

2. They hit peak production for several times of a daily power production ..

3. Many tier 1, I observe works 58-73% efficiency of their power when at maximum and more predominant around 60-63% ... Could be more but maybe not observed while tier 2 works between 45-65% maximum that I have observed but mostly 50-55% is predominately constant

ojeysky:
Curious to see what the "tier 1" generation log looks like. I have both prime(yingli cousin) 380x7 and sunfit 280x9 with orientation a little bit more on the side of prime yet both are doing 3x easily. They do burst to 4x occasionally on sunny days.

Except you want to get this items yourself, no pro-installer or company will sell these items for you at expected rates ...

And some of the prices above are a bit off, mostly undershot

And since you said money isn't a problem in earlier post .... All you need is just 5 bricks of sweet 2.4KWh pylontech and you have 10.5KWh ...

Which means in 6 - 7 years you will have change your lead based battery 2- 3 times and with ever increasing dollar rate ... The cost of will be like 3-4 times more if you had gone with lead based batteries

cluewebhost:
Panels : 16 x 70k = 1.12m
Batteries: 8 x 120k = 960k
Inverter: 1 x 250k = 250k

From prices here is that right? Excluding installation.

Great! please when ever you are ready ... Let's know your experience

IYGEAL:
I'd write a review to the one you brokered for me. I'm impressed by the performance, especially the charging and compatibility with lithium chemistry.

Don't have a early victory lap yet I meant usable storage for Lead based so you need like minimum of 8 batteries

Good luck in setting things up, but in case you need a pro-installer.

Kindly shot your message to contact on bio

Cheers

cluewebhost:
Wonderful thanks!

So

5kw inverter for proper charging (I think it's even better if I need to expand load a bit later)
9.6kwh storage - 4 12v 200ah batteries?
+ good panels.

The brand's that are Tier 1 are many but I will list a few that are peculiar to Nigeria

Jinko
Canadian
J.A
Trina
Risen

As regards your storage, you will need minimum of around 9.6KWh to run your preferred loads

Problem is 3KW inbuilt charge controller will not fully charge your battery so inclusion of an extra charge controller is needed but with lithium batteries you will need a 5KW inverter hybrid to slap the solar panel on without an problem.

cluewebhost:
Thank you!

1. Yes I usually have 12 hours per day and without the AC that consumes 2kwh in 24 hrs

2. A refrigerator (100w I think the stabilizer makes it higher though), Standing fans 2 20w then LED bulbs and laptop (45w) once a while

3. Yes night time only

What brands are tier 1 (these are the confusing issues )

Thanks a lot!
I was thinking 3Kw too.

To better understand you

1. You have grid power fpr 12 hours daily guaranteed?

2. If you can kindly state those negligible loads you mention so as to know what's best to recommend

3. By Asleep you mean the night time right? Or just random hours in a day-24 hours


A 3KW hybrid will do the job for you and to better rock the boat well ..... With regard to solar harvest .... A Tier 1 panel will be a recommendation but incase budget is tight ... Tier 2 fit pass too

cluewebhost:
I've been going through this thread and I'm confused.

What sort of setup would I need (solar) to power this AC?

I only need it on for 6 hours when I'm asleep

It shows 940W and 4A.

The rest of my load is negligible I use 2 - 2.5Kwh a day for 12 Hours of grid power - Refrigerator, Computers etc.


How many panels would be sufficient?
How many batteries + capacity?
I assume a Hybrid inverter would work but would 3Kw be okay?

Is there anything else I should know?

If you are interested to get this I can get a very sweet deal, don't know how long the offer is open for but only for the 24V variant

lexi28:
What is the price for the growatt?

Good morning everyone and happy weekend to you.

I notice a recent trend of Axpert based tech or clones having board issues and complete shutdown, while this is sad to the users and a loss of investment

It is important to note that many of these inverters with LVD have always and have being surviving Lead based batteries before now without any issue.

My pick of the whole scenario is that all attested testimony of faulty Axpert variants I noticed here have always being with DIY Lithium based batteries with BMS .

In reality all information to draw a conclusion from what happened with the battery mostly goes down with the inverter when it went bad .... But one thing to note is that

I believe that the BMS does something that indirectly hurts the board or electronic components built-in.

My own solution to the DIY Lithium owners will be to lose some energy storage by increasing their LVD to be above what the BMS will do normally so the battery retains some energy while only your inverter goes offline.

And since it's hybrid ...once the sun comes on the battery gets juiced up.

I'd advice that you get the following accurately

Power consumption of all you have listed below and state the hours you'd like each to run for either day or night.

This way your storage capacity and inverter capacity will be determined.

Else I am afraid you might end up with a half baked solution you won't like. So better to have a road map for things now and work towards it.

I can share with you a form that you can fill and return and I can help you at my leisure.

Happy weekend!

olise88:
Good afternoon. Please, I want a solar structure as well as batteries for my household appliances( TV, Fans, bulbs, deep freezer, fridge and other minor appliances). But I want the fridge and freezer to be always on (24/7) while every other appliance can be average of 12 hours per day. I'm thinking 4 batteries of 12v200Ahr, 6 mono crystalline panels of 200W and an inverter of 12V2kva will do the job for me.

Please, kindly advise on how to go about it because it's urgent. Thanks.

Easy fix

Loosen the back of the fan and located the moving parts, get a good oil that won't evaporate on heating of the coils and carefully apply it on them.

Couple back gently and power it up.

You should be back enjoying that cool breeze

Cheers

ojesymsym:
When a standing fan begins to have a humming sound when on and only starts rotating when the blade is rotated, what needs to be repaired? The capacitor at the regulator part has been changed, the refusal to rotate still persist.

All the fan repairers I used to see in the area seem to have disappeared.

No, it's not independent of battery

IYGEAL:
Okay. Thanks.

Please do you know if it works without battery?

It has a good idle consumption on no load

7-15W

And when like 70% or close to max. Load.

30W - 100W Or less

IYGEAL:
Well noted.

How about idle power consumption?
Can it work without battery?

What I meant was that the 600W PV you have will never charge your batteries full any day of the year

Except you have grid available for up to 18 hours cumulatively then it's no problem at all.

abbeymighty:
some one want to give ipowerplus hybrid inverter but have already have 4 batteries using presently with pure sine wave that is not hybrid.
at bold I don't understand what you mean.
please is growatt hybrid?

Just watch closely

These equipment ain't cheap so log your information to be sure to know when something isn't looking right

durodee:
Good morning house, I was recently faced with a challenge. I have a 24v 5.4kwh LiPO4 bank and a 600amp 24v used Ritar battery bank. Tested alone the LiPO4 did not meet my daily need. It will usually go off around 2-3am (when I personally need it most!) and the used batteries much earlier at around 12mn at times.
I was discussing this challenge with a friend and he told me he connected his LiPO4 and SMF bank together(in parallel) to the same busbar and that has resolved his problems.
So I checked online https://community.victronenergy.com/questions/19981/mixing-lead-acid-and-lithium.html and realized many others have tried it with the pro and cons, different charging and discharging profiles mainly.

So I connected 200amp of the Ritar to my lithium bank to test run. I also used 28.2v bulk and 27.4 float charging profile on my inverter and CC. All connected yesterday evening. I was able to use the system overnight and even ironed with it this morning, however I was aware there was grid supply at some points overnight and therefore I can't say if it works or not.

It is early days yet. The risks are shortening the lifespan of the lithium and undercharging the lead acid but based on what seems to be happening as described by others, due to the BMS, lithium charges and discharges first and the lead acid charges and discharges last.

I will update the house on my experimentations and hopefully, no big bang episode!

Easier if you have your connection reconfigured

Assuming you used 150W which has up to 23V as VoC

Choice is all yours to make.

Cheers

IYGEAL:
Growatt 24v hybrids I see can't take my current 8s1p PV voltage input.

I may have go SMK again or get a standalone 24V wall mount inverter and a separate CC.

Any suggestions house?

1. Remote monitoring

2. Configurable parameters

3. Lithium compatibility

4. 100V max. For 24V variants

5. Up to 1500W max. power, over sizing is allowed

6. Atheistic design

7. A medium range product for money.

In case you plan to get one, I can hook you up.

IYGEAL:
Why though?
