Good morning good people, I had this 6.2kva hybrid inverter set up with 4 turbular batteries, and my 9kva elepaq generator wouldn't charge it for whatever reasons, it does charge for a few minute and it stops at some point, what could be the cause?
What's the charging current of this hybrid inverter?

Hello boss I have a question I know that the design is wrong but the electrician has already tell the customer that he can use 6 batteries for 48v system. Is any thing that can be done without positioning the battery close to the working unit?. N.b the customer is a family member and he is not agreeing to a change of design
The family should not bother employing such quack. Unless the house is insured. Then they can deal. Electric fire is about to occur after the installation.

Abeg make una help me o. Is it normal for a 550W panel of 48V VOC to drop to as low as 26v when under load in proper sunlight.
What is the Vmp? Do you get close to this VoC on the solar panel when you measure the voltage without load? The drop is excessive, you should check your wiring if the measurement is close to the specs. Most rebadged solar panels don't perform as the spec sheets state.

Call them to confirm the position of the items.
This has been done several times with customer service just giving bland answers like "we will confirm and get back to you" etc with nothing concrete to say. Worst online buying experience for him.

I can bet your cousin didn't follow the instructions very well.
In making payment you must input your order number and that fouani account name in the narrative the you go ahead and mail the receipt to there email that will be given
He did, those guys are just plain lousy.

The 320 watt is KBC
. The 580 I am planning on getting is jinko 580
.Comparison of Configurations


Parallel Connection:

Voltage: Limited by the lower voltage panel (33V).


Current adds up:

Combined current is Imp1+ Imp2 = 13.69A+ 10.6A= 24.29A

Ptotal (Total Power Output) == 24.29A X 33V = 801.56w



Series Connection:

Voltage adds up

Voltage: Combined voltage is Vt1+Vt2 = 42.37v + 40v = 82.37v



Current: Limited by the lower current panel (10.6A).


Ptotal (Total Power Output) = 10.6A X 82.37v = 873.122w


Conclusion

While the series connection yields a higher theoretical power output of approximately 874W, it is limited by the lower-performing panel's current (10.6A). If the 320W panel experiences shading or inefficiencies, the entire output drops significantly.
In contrast, the parallel configuration provides a more reliable output of approximately 802W, ensuring that even if one panel underperforms, the other can still contribute effectively.

Thus, for systems where shading or performance variability is a concern, parallel connection is generally better due to its increased reliability and consistent performance under varying condition

This device is a one way direction counter.


I would recommend you get a Bi direction Coulumb Counter BT version, especially to monitor battery usage. though they are not cheap.

I am testing the WiFi version with Screen.
Did you source the WiFi version locally? If yes, how much? I've seen it on AE.

ask4bk:
If I run AC, that thing that consumes 1kwh, by morning won't it finish my 14kwh battery? Except i run it for like 6 hours at night only.

But truth be said, during the day the panels are wasting coz after charging at 4kwh from solar, once its filled up at 10am, it reduces to 400w which is all I use during the day. Over 3kwh from solar that could handle AC is just wasting.

To consider again is, do you think it'll stress the 5kva felicity inverter?
If it's an inverter 1HP AC the consumption is actually less. Yesterday I did 11 hours and 57 minutes m, let's just say 12 hours, and used 6.87kwh. that's like 0.57kwh per hour. So no, you won't use 1kwh every hour.

Who's bought all those Kitchen, Dining, bedroom and home furnitures I see on AliExpress.
A full table, large Drawers etc. with different parts and section, $7, 8, 9 dollars. how?

I've checked over and over again to be sure it's what it is, it is. They are many there
All under 15, 12 USD... with free shipping
Those things are likely toys. Ask seller to send you real life picture of the furniture with people standing beside them to check for scale.

Inverter technology has no starting surge, so no.
Thought as much. The OP on freezer should get an inverter freezer.

I need review on this Solar Panel

Type = 200W Mono
Price = ₦53,000
Brand = Sun Field

My questions are:
1. Is this panel genuinely mono?
2. Is the price reasonable?
3. How reliable are Sun Field products?
4. Overall, is this a good-quality Solar Panel?
Not too bad according to the price. Not tier 1 though. Good for someone starting off the renewable journey that is buying materials that won't break the bank. I've seen loads of Sun Field products in the Nigerian market. But Sun Field is not a known company outside of Nigeria, I suspect an importer just slapped that name on products they customised/bought in China for sell in Nigeria.

That said, I can't say anything about the reliability as this name brand is only seen in Nigeria. Haven't used any of their products though.

What I have heard is that the inverter ACs are not as good in terms of cooling.
Cooling is not an issue for mine though. Make is LG. That AC practically turns the room into a dry ice cold room.

True. For example, my freezer surges to 850w for a few seconds before dropping.
Easy solution to starting surge is to use two different outlets and timers and just set them about ten minutes apart.

For example, my freezer surges to

Thank you.
This breakdown will help a lot.

Could you please recommend an inverter to use for this?

I had a guy recommend hybrid Felicity inverter offline, do you think this is a good option?
So sorry for the too many questions already.
Felicity not bad. Transformerless hybrids are cheaper but often, in general terms, not as rugged as transformer based inverter in handling surges. Felicity IVPS/IVPM series are transformer based. The Felicity IVPM has hybrid series. The Felicity IVEM hybrid models are transformerless and of course cheaper. So you can check out Felicity's IVPM hybrid series.

Inverter ACs vs Regular ACs?

Are the inverter ACs energy efficient enough to justify their extra cost over regular ACs, which are also getting fairly energy efficient on their own?

What are your thoughts folks?
On 23/10/24, for 22 hours and 15 minutes, the total energy consumption was 11.36 kWh. That's an average of 0.51 kWh per hour—pretty impressive for a 1 HP AC. Someone should do the same for a non-inverter AC; let's compare.

So far, I have no regrets about paying extra to get an inverter AC. The AC make is LG, and it is a Dual Inverter model.

FYI: Figures may change due to a variety of factors, such as the temperature of the location, room size, room insulation, how many times doors are opened and closed, the number of people in the room, the temperature set on the remote for the AC, and the AC mode in use, etc.

What solar setup would you guys recommend for a frozen food business on a budget?

Aim is to use 2 freezers.

Do you have any efficient freezer you can recommend too?
Check for any inverter freezer with low wattage.. check specs on the freezer before buying. Scanfrost inverter freezers are pretty energy efficient. I'll attach the spec sheet of a 215L non inverter Scanfrost freezer as an example.


You can start with the following:


1) 3kva inverter (preferably transformer based inverter)
2) 5kwh of battery
3) 6 nos of 400w Solar Panels for a start. You can increase this as business grows.

The freezer (attached below) at highest consumption takes 160w, that implies if it runs for 12 hours daily it'll consume 160w X 12hours = 1.92kwh. So 2nos of it is 3.84kwh. You don't really need to run it up to 12 hours as it'll be frozen long before this.

Let the ogas at the top provide cost of above. Cheers.

I got it for a friend, so i only check up on the system on weekends. But what i could sample for now it carries one pump at a time.
2 surface pump ( 1hp).
1 submersible pump (1.5hp).

The first cycle starts in the morning 10 am.
Second pump cycle starts at 3 pm.
All 3 tanks are filled twice a day. For fish farming.

Sako hybrid 3.5 kva 24v.
Thanks a lot for the update . The inverter is doing ok then.

Okay, last month i bought a sako hybrid inverter from a nairalander here (nexus). To cater for the same thing. 3 tanks to be filled at least twice a day. 24v system. Just adding panels gradually but so far, it okay. How many litre tank do you fill.
How has your Sako hybrid experience been? I'm thinking of using it for a project. The pumping machine is how my HP and which of their capacity did you get?

Sizing your solar system and energy efficient equipment is the key. I use my gen in a very very bad weather conditions, around that August. Before I switched to LifePo4, about a year ago, I use an average of 20litrs or less in a year to run my gen. But this year, I have not use 1litr of fuel, desipte the bad weather conditions from July to September.

But always keep your gen handle.
For the past 7 years, I don't own a gen. Out of 7 years I stayed two years without NEPA (Naija is not a real place. NEPA downtime due to bad transformer, many packed out of the area). Zero personal power downtime in all these events. In bad weather I just drop high loads and life continues. As a backup/solo use, RE is king.
