Bolt them up in series.

Boss he said 12v system ooo. Max those 60a mppts take is 800w

Dam5reey1:
Cworth 24V 100AH, available for 575k 540k..

Scatter the market sir... We dey ur back

Dam5reey1:
Just know what you are doing, you can safely do it for science.

U dey find comrade join u sir...

Nteogwuija:
I'm facing same issue. Mine is CWorth's 350w(×3) equalling 1050w. The highest I've gotten during peak period is 535w.

I'm staying at the down floor of a 2 storey building, making it difficult and costly mounting the panels on the roof. So I had to install it by the side of the building. So I'm guessing the building is affecting the PV's output.

I'm curious at how mounting it on the roof is costlier? How did you install it by the side? Metal brackets or how? U wud be getting shadows which wud limit production. The only thing expensive using the roof would be the length of wires used which in the long run wud give more efficiency than the side u used cos of the direct sun hitting it without shadows

Mrreed:
I have seen it many times. Sako 5.5kva, I used Jinko 450w x4 and the yield was below 10% till I added 2 more panels.

What VOC were u getting with the initial 4 panels? I usually try to get around 150v and it works well for me

ManAdii:
It's not just the building. Cworth panels are shit. I have 5 of them installed and the highest I have gotten from them at peak sun is 1.2kw out of the 1.75kw.

Even when I tested it with my multimeter before mounting it. The Isc is not up to what is on the label but the Voltage is.

Different strokes for different folks. Some other ppl av vouched for the panel performance. I hope ur roof inclination/distance isnt the issue here. Also the battery voltage/load cud also be the culprit here. U still getting over 68% yield which is better than many fake sticker panels output.

HeavenlyBang:
Growatt 48v 6kw - ~500k
Eight Jinko 550w - 1m
Not sure if there's a 10kwh Deriy pack but it's probably your best option here. You go need extend your budget to 3m last last but this should take you off-grid entirely.

He can still do 4 based on his budget and manage it with grid pending when he's able to add panels on later.

AinsSama:
Welcome fellow enthusiast.

3.5kw 24V hybrid inverter (Welion, Sako, SMS, Growatt) - 350k
5 600W or higher-rated Solar panels (Jinko, Canadian) - 700-800k
24V 10kwh Lithium battery (Deriy, CWorth, SMS, Sako, DIY) - 1.3-1.6m
Installation materials and installation fee- whatever change is left will do this.

Make sure whatever item you're getting is genuine. Reach out if you need any assistance in getting them.

Apart from sms and maybe deriy, u wont get others at that price range?

Mrreed:
I am waiting for Dami to buy one for science 😁

@dam5reey1 come and do it for science sir

GloryJoyeux:
Hey folks,

Just wanted to drop a solid recommendation for anyone considering the new Deye 6kW hybrid inverter. I recently got my hands on one and have been running it pretty hard to see what it’s made of — and honestly, I’m impressed.

First off, it’s parallel capable up to 16 units, so scaling up is no issue. Efficiency-wise, this thing is tight — I clocked idle power draw at just 30W when running a 1.6kWh load, and it only pulled under 100W even with 4kWh flowing. I also put max sustained load of 6kw, it took it like a champ! That’s some seriously optimized idle-to-load performance.

Now, let’s talk MPPTs. The Deye has a new feature under Advanced Settings called “MPPT Multi-Point”. Game changer. One of my PV strings gets shaded after 1PM, and normally performance drops off hard. But with this setting enabled, the inverter kept pulling full amps from the unshaded panels — like it knew exactly what to do. I ran the numbers — the gain was legit.

Sound-wise, it’s practically silent. It uses just one fan, which only kicks in at high loads. No annoying coil whine either — just a soft whoosh when it ramps up. I’m running 10,280W of solar into it, though it can handle up to 12,000W on dual MPPTs. It charges and discharges at 135A, and with an IP65 rating, it’s perfect for our dusty, humid conditions. Built-in WiFi made setup easy and remote monitoring is clean.

Small Catch:

Since it’s a newer model, Solar Assistant doesn’t support it yet, but I checked — it logs every 60 seconds and pushes data every 5 minutes to the Deye app/web. Accuracy is within 98% of Solar Assistant’s metrics, which is impressive for a stock system.

I also tested it with both closed-loop (BMS comms) and open-loop (voltage-based) battery setups. It handled both without breaking a sweat.

Cost & Efficiency:

It set me back ₦950,000, and honestly? The performance outshines Growatt, Axpert, Sumry, Welion, SMS, Sako — pretty much every other popular Chinese inverter I’ve tested.

One thing I’ve noticed with a lot of these cheaper all-in-one units is they use low-quality conversion components. For example, an SMS inverter I tested lost a constant 4.5kWh/day due to inefficiency. Doesn’t matter if you’re generating 9kWh or 30kWh — you’re losing a minimum of 4.5kWh daily. That’s 135kWh a month gone. Discharge efficiency was also poor — I was only getting 86–89% usable energy out of a 10kWh battery.

With the Deye? I’m seeing up to 96% usable, meaning 9.6kWh out of a 10kWh pack. That’s a huge difference.

Testing Other Brands:

I also tested the true output of other inverters, and most are overrated. A “6.2kW” Sumry unit (sms, welion, sako, powrmr, anern, victor max, daxtraumn etc) barely managed 5.6kW sustained, and a “10.2kW” SMS one capped out at 8.2kW. Turns out, they rate them based on PV input, not actual AC output — which explains a lot.

My Brand Ranking (So Far):
• #1: Deye – most efficient and best built
• #2: SRNE – decent performance, but not quite Deye
• #3: Growatt – solid, but a step below SRNE
• Way down the list: Felicity Solar and similar budget brands

That said, I do have beef with SRNE’s pricing. They’re trying to pass off their gear as premium because they’re UL-listed and in the U.S. market. But their 16kWh battery is way overpriced for what you get. It’s just REPT cells rated at 8000 cycles (anyone can get their hands on this cells, and no guarantee its actually grade A sef), and nothing special inside — no thermal padding, no fire suppression, no fancy BMS features. You can get better-built packs from Deriy, Bicodi, Gospower, Lvtopsun, or Valtech for less.

Quite a long read, if you have any questions you can ask me.

How would u rate the sumry units in order of performance?

Mrreed:
If you can afford to spend the total here, here is a better option
There is a brand "Haisic" that sells
25.6v 8kwh for 800k (as contained in their spec sheet, it's a Grade B battery)
24v 4kva transformerless inverter 340-350k
590w Jinko panel x4 is better
6mm cable, breakers, SPD and the box will cost you less than 160k if you are staying in a bungalow and will be installing the system close to your DB

You the second person mentioning this battery brand, how well do they perform?

dollarnaira:
Personally I will make use of the monos only:
38.2 × 4 = 152.8v for 24v (max cc 160v)

While the max VOC is 160v, its 105v max if using a 24v setup

CaptainZubi:
I noticed my inverter starts beeping and eventually turns off when there is little sunlight for as low as just 10 minutes (when gate and compound lights are on). When tv and fan is also on, it starts beeping in as low as just 2 minutes and then goes off. In a nut shell, e wan be like na when sun dey blaze e dey function well.

Then after careful thought, I decided to disconnect the MPPT charge controller and connect the batteries and solar wires directly by bypassing the charge controller. Omo rain fell for 2 hours and I still had light with TV , fan and every every on. If it was before, the inverter for don off coz there is little sunlight. What could be the issue and what could be wrong? I'm a novice on solar energy but it seems like the charge controller is not allowing the batteries to charge properly. That's what I'm thinking.


Is this also a good or bad decision?

You are at risk of fire outbreak from ur batteries by bypassing the charge controller.
You didnt mention the wattage and nos of panels plus how they are arranged either in series or parallel?

toscotech:
i dont get how to enter setting

How to set the settings are in ur inverter manual. Press the enter button for a few seconds to enter the settings page and then ffl the manual

Obnoxious2001:
Set as user defined. I think option 05 in the settings menu

Then set float and buck to 56.5 I think option 27&28

Then set your low battery cutoff option 29.



Please use manual to confirm what I typed above...

Cutoff to 29v, sure its a typo. Your low voltage disconnect sud be at 48v

Valto:
48v 3000w (1500w continuous power ) pure sine wave sachet inverter available 105k

Nice one. Wud revert soon

adrusa:
Do you have this inverter in 48v?

This wud have been wonderful but the price was the turn off

Obnoxious2001:
I Will likely be posting how we repair and carry out troubleshooting of hybrid inverter.
Error 09, Error 52, Error 53, Error 57 etc.

Mind you I am hoping to pen down this fixs so I can get to learn more about fixing this inverters from senior men who are behind the scenes, then also to help lot of DIY/hobbyist carry out repairs too......

Hopefully I stay committed to updating this logbook.

Following!!! Mind to tell us the solar company u working with? 😁😁😁

GloryJoyeux:
My solar yield this January.

The heat this time of the year caused a significant drop in solar yield. Always remember to factor in the temperature coefficient when purchasing your solar panels so as to have a realistic yield estimate when you factor in the different temperatures we experience throughout the year.

10.2kw sms dual mppt
10.28kw panels (12x440w Jinko and 10x500w cworth)
18kwh cworth lifepo4 batteries ( 2x100ah and 1x150ah)
Solar Assistant on Raspberry pi5
Victron smart shunt 300a
Junktek shunt/battery monitor 100a

Achieved 100 percent off-grid status in January.

Take not, load does not factor in the 100wh consumed by the inverter itself (72kwh in 30days)

Peak continuous solar yield this month was 6,500kw i.e 63percent max yield

Peak cumulative load this month was 5.2kw

Max yield - 34.1kwh on Jan 20th
Lowest yield - 12.5kwh on Jan 19th

Max load - 24.3kwh on Jan 27th
Lowest load - 9.8kwh on Jan 19th

Max solar yield in 7days - 205kwh between Jan 17th - 23rd

Average daily energy consumption 20kwh

Something a lot of folks miss when trying to go the renewable energy route is using energy efficient appliances. Converting all appliances to energy efficient ones is as important as getting panels and installing batteries. As you can see, most of my appliances are energy efficient.

Energy management is also an important factor, I make use of smart switches which are automated to turn appliances on and off for different set durations.

My biggest energy consuming appliances for the month of January:

1. Lg 1.5hp inverter air conditioner 184kwh
2. Lg 1hp inverter air conditioner 84kwh
3. Starlink and own router 59kwh
4. Double door fridge 52.3kwh
5. Chest deep freezer 34.63kwh
6. Heat-pump clothes dryer 27kwh

*Sorry for any typo

Just how well does this SMS perform and would u recommend it? Av my reservations though but good to see a positive review

Dam5reey1:
Boss, cable wey we dey manage, e reach your turn you want to buy everything

No mind my oga oo

SourYoghurt:
hello folks, I need you guy's input on this. I have 3× 550w Jinko panels with a 12v battery from Va.lto and a 2kv sunfield hybrid inverter, I don't exceed 510w from the PV even during peak sunshine. Most times to get 400w+ I'd have to off and on the inverter. It is always around 260w.
And the panels surface are clean. I was expecting at least 1000w input from the PV or is the connection faulty?

For sunny period I dey see 500w, what about rainy season, how man go survive?

U sud check ur panels connection. Have the same inverter installed for a client with 2 450w and i was getting abt 600w with good sun during a routine check

maklelemakukula:
Thanks for your input. This is my first solar project so I intend to use a well known brand. When it's time for the next one I'll use Valto.
I haven't bought any panels yet but intend to buy 8 615watt jinko panels, will these be sufficient ?

Lolz at ur 'well known brand'. U sud google them and see ow a few do not even meet up to their advertised capacity

Compliant:
Thank you for your input Sir

Now, should I get 100A CC to replace the 60A CC since I am not upgrading the batteries now or I should stick with the 60A for now

My main aim now is to charge my battery faster without connecting to the grid

Await your suggestion

Ur limiting factor is your battery so even if u change to 100amps, u might end up boiling ur battery.
Tubular battery charges slowly. Read up the 3 stage charging stages for tubular and also the need to equalize monthly

jonescosmos:
Na me pay ooo. my brother I hope you read the part where I said the setup didn't last upto 48 hours. Which Client go wan listen to your excuses and troubleshooting in such instance? I jejely respected myself and bought another Inverter and Battery and installed for them ooo.
It's a painful reality ooo. That's why some products are so popular while some will never make it past Alaba market. I am someone who never installs anything lower than Growatt and Felicity for clients. After hearing lots of noises about SRNE, SAKO, SMS, etc etc, I decided to try out the SAKO due to client's low budget.
See how the whole thing ended up. This Installation almost messed up my Xmas ooo. Anyway sha, Lesson learned in hard way.

Any client that wants a low budget installation henceforth go buy the devices themselves, my own na to install am for am with plenty of caveats.

I can imagine how u felt. Unexpected expenses.
I may just be doing standalone inverter and charge controller for low cost setups to protect ny peace

Haykay2001:
Hv been asking them for their service center address in lag, no single reply.. Just so sad..

Who have you bin communicating with? Did u use a low voltage disconnect on the inverter? Whats ur charging current too?
Battery has a 5yrs warranty so best is to return it and try to find cause and prevent a repeat

jonescosmos:
I will disassemble the battery when I receive it and boost charge the cells directly to wake up the BMS.

Of course I know this is going to be the what I will resort to but which client wants to see you doing such with something that haven't served for 48 hours? And that's the reason I just replace the both units so save myself the stress. Abuja to Abia is not a 15 minute journey ooo.

Out of pocket or client paid?

hayzhed:
An installer once told me that it better to use and external charge controller on an hybrid inverter with inbuilt charge controller. He claimed that it reduces the stress on the inverter. Please, how true is this claim?

Not true. Less said, the better.
Only reason to add an external charge controller is if you already used the maximum panels size ur system can take.

EduTechTainMent:
Who has experienced this issue with felicity hybrid inverter IVM 3024 and sako battery?
Setup is not giving any power output. 3 pcs of 555w jinko panels connected in series to the battery

Ur inverter is most likely the issue. The battery is showing no current leaving or entering into it.
Not sure the panels would work as u need at least 120v from the PV for it to start charging which u not likely to get with those 3

dayomuritala:
Pls what's the rated power of afripower 1kva inverter

About 800watts. Wont handle surge above 1000w

Get a lipo4 with smart bms. The LVD can be set to 12v so it trips off the battery or play the human observer and ensure u switch of once battery gets to 12v

Dam5reey1:
You are quoting even VMP.
3p + 2p may work with some losses on the extra voltage of 550w. So all will work as 5p 435

.
Won't the PV current be too much with this 5p combination? Why not just series the 3 435 and keep the 550 for future upgrade

606thearena:
He does not have the 10kwh . Any other reliable people that sell batteries here on Nairaland .

Sako, sms, cworth. Do ur due dilligence
