Bro what is 2s 3p
2S= 2 panels in series
3P = 3 panels in parallel


Let me use the diagram below to illustrate 3S 2P

Panels 1,2, 3 are connected in series = 3S

Panels 4,5,6 are connected in series too = 3S

Then there is two parallel. Panels 1,2,3 is in parallel with Panels 4,5,6 . Notice the parallel connection between Panels 1 &4 (and panels 3&6

Panels in series are connected + to -

Panels in parallel are connected - to - and + to +

PV Plus and PV Minus goes to the charge controller PV + and PV - respectively.

Thanks. I ended up paying the 306k. Just wasn't ready for the hassle. Big mistake not checking the shipping method before paying. Never made that mistake in all my years with Aliexpress. Never again.
You are welcome

He is doing 6p based on the PV Voltage on the screen... It shouldn't even get hot as there is not much conversion...
3s2p/2s3p maybe hit or miss.. he can try his luck...
Just checked again. Thought the temperature is voltage. Lol.

Some installers are crazy. Why would an installer opt for 6p after swapping out a PWM? THAT'S the problem then, Kendzyma get your installer to go and change the configuration to either 2s 3p or 3s 2p. He did 6p which is the reason the charge controller is running very hot, low voltage and high current are often recipe to high temperature. Also your MPPT won't work well at such low voltage. That'll explain the poor yield too.


That controller is not bad, I have friends using it without issue, just remember to set the battery type you are using

Hi Everyone. I have a 2.5kva setup with 2 12v 220ah tubular batteries (24v system), I also have 6 300w panels connected on series (not sure, installer did the whole set up, but the said it's in series) .

Issue is, I have been using a pwm 60amp cc with it for a while now that works fine, just decided to upgrade to powmr 60a mppt cc which I installed yesterday, but I have been getting an abnormally high temperature from the cc, like 60+, which the highest I have gotten from pwm was around 40. And I also noticed a reduced battery time when I am on battery compared to when I was using the pwm...


what could be the reason for this temp increase and reduced battery time?
From the PV voltage I suspect that the connection was 2s 3p. See if you can do 3s 2p to reduce the current coming into the charge controller. Would've asked if the cooling fan is working, but this design doesn't have any.

Hello house.. I trust we are all doing good and I must salute every solar energy professional and users in this forum for their contributions. I've learnt a lot being here.

Please I would like to ask if anyone knows where I can get very durable batteries for rechargeable fans. I need a 12v7.5A, 6V4.5A. this is very urgent.

Either ready made or DIY, as long as it'll be durable. Thank you all for your contributions.
Check any local market that sells things like electronic parts, fan repair area for these batteries.

Please what is the best specification of solar panels to get for a 12v 115amps battery. I also want to be able to power a hot plate rated at 1000w during the day when the sun is up. I want to go completely offgrid. Need inputs from everyone please. I am tired of Nepa. I have the battery, intend to get the Inverter and Solar Panels.
A 12v 115ah battery has a total energy of 1380wh which if it's a lead acid battery has a 50% usable capacity, that is 690wh. If you are to run a 1000w hot plate on it it'll last for 690/1000= 0.69 hours or 41 minutes in theory.

Conclusion: It's not recommended to run a hot plate off such small size of battery. Also it'll be hard to get a genuine 12v inverter that can handle such 1000w load in Nigeria.

Abeg Veterans abi experts in the house. If you are carrying 80amps from your charge controller output to your battery. What size of wire do you use. You guys with 80A, 120A controller for a 12v system. My controller and battery are quite close to each other. This my online calculator is telling me 26mm. How will 26mm wire enter this tiny hole in this charge controllers. Not sure I am doing my calculation right
What type of charge controller are you using? Can we see pictures for PV wire and battery connections on the charge controller?

Good day guys. I have a pending Aliexpress shipment using DHL (It was a mistake, I didn't even check until after placing the order). Anyways as expected, I was charged custom duties (About 110k). I got a link via SMS to make the payment on their official payment portal. I tried paying several times but was unsuccessful, only for me to check back this morning and I'm seeing an almost 300% increase in the charges (Now 306k custom duties to pay), which is honestly ridiculous. Is this normal? I can't even get them on call via their customer care line and they're not very responsive via mails. I'd appreciate any assistance I can get on this. Thanks.
If you have a penchant for some risk taking, you can try what I once did in similar circumstance. I refused to pay the duties and the package was returned to sender. I filed a dispute and got refunded. While this stunt may not end up as mine did, it's just something worth considering should you see paying this hefty sum as something you can't do.

Ask ur installer to bring down 1 panel first, check d spec n use the info provided in our previous conversation to make ur decision. Nothing confusing, u fit just pay d installer more for d added stress, it's not something that can't b done.
Installer doesn't even have to bring it down, can only remove it and snap the specs on the roof.

12v system.


It was wired in parallel but when I moved to a new apartment, I tried to wire it in series if there's going to be any changes. I didn't notice any significant difference.


I'll follow up with pictures of my MPPT display later
Some factors that may affect the performance of solar panels include:

1) The quality of the 300w panels. Some 300w solar panels are not truly 300w. They may have the 300w sticker, but in reality they are at most 220w or 250w.

2) The orientation of the solar panels. Some roofs make it hard to get the best yield from the solar panels, especially when special roof mounting structures are not used to adjust the tilt angle . Nigeria is slightly north of the equator, so solar panels have to face south. However, since Nigeria is so close to the equator, panels would be facing almost upward with only a slight southward tilt... maybe less than 10°.

3) Shadow factors. If your solar panels are fully or partially shaded, the yield produced will be low.

4) Mounting solar panels on the wrong side of the roof. The direction of the roof affects the amount of sunlight that the solar panels can receive. Best to mount it on the south side see No 2 for reason.

5) Dust. Everyone is experiencing low yields, especially now that the dust has covered most panels.

6) Solar panels rarely deliver 100% of their rated wattage at all times. The actual power output depends on various factors such as weather, temperature, and time of the day.


Solution: Check you are not constrained by any of the above, and also consider increasing the number of solar panels to four. Two numbers of 300w solar panels may not be enough for sufficient charging of your current battery set up.

Hello guys. Please help me out. (I am willing to pay consultation fee)

My MPPT ratings is this:
Max Current: 40a
PV input power
12volt system: 12v 540 watt
24volt system: 24v 1080 watt
36volt system: 36v 1620 watt
48volt system: 48volt 2160 watt.

I want to use charge my double 12volt 200ah batteries. To follow the specification, I arranged with a someone to help me get a 600 watt solar panel. Because 600watt solar panel won't come in 12 volts. I paid for four 12v 150watt panel.

When the panel was delivered, it was a double 24v 300 watt panel. I insisted on returning it but the seller was aggressively convincing that the specs won't matter. 24 volt will still work and all that.. blah blah blah but I gave in sha.

Since I have connected it, I feel like the charging is not working to its maximum. The charge controller specifications is 24v 1080 watt but I am using 600. Maybe that is why it is not working to the maximum.

So far, the highest I get is 240watt an hour when the sun is at its brightest. I don't know what to do.

I don't know if I should sell the panel and but another set of four 12v 180/150 watt and sell this one.

Or I should buy another inverter which is 24volt and wire my battery in series.

Or I should buy another MPPT charge controller?

Please help out.
What is your inverter system voltage? Is it a 12v system or a 24v system?

How is your 24v solar panels connected? Is it in series or in parallel?

You can share picture of your battery connection and the mppt solar charge controller display (during sun hours). This can help answer above if you find it difficult to do that.

Boss,
Please does anyone know why Sma Hybrid 12v 1kva inverter will be showing 09 fault code.
In the manual it means bus soft start failed.
It’s a new inverter.
This indicates a problem with the inverter's IGBT or DC-DC MOSFET, which are components that convert DC power to AC power. This could be caused by a high AC surge or PV surge that damages these sections. You'll need it to take it to a service centre for repairs.
