Am sorry bro
But I laughed out loud upon the above.
Not dust on the panels o. But huge dust in the air above affecting everyone Jinko or no Jinko. Wait for the first or 2nd rain to wash the said Harmattan dust in the atmosphere off. By then, sun rays will fully hit your pv wella. Dust don chop better part of the sun comot. So bro, the sun you are feeling now is big fake. Leave your set up till March/April and check again. Cheers.

You have no problem.
The panel is trying your concern should be to increase your cc.

The 40A can only fend for 550w × 2.
That if you don't have plans to install the 300w panels

Dam5reey:


If a Jinko already produced 275W which is 50% of its capacity and your 300w were doing 100w which is 33%...
it means your the Jinko already performed as Top Tier Panel.

Your Charge controller is doing a bad job... Change it to another one..

Also note the Current Weather is very bad!!

easyyoke:


What brand is your 580w panel and where did you get them please. You are getting about 80% yield and that is a very good yield. Your panels are original panels. I am getting just about half of my own rated wattage. What brand is your panel please and where did you get them?

easyyoke:



What Brand would you recommend as a good MPPT charge controller. Something in the 80A and above range because I plan to add more panels later

Hmmm, this is not efficient, 300watts panel is connected to PWM CC on a 12V system.

easyyoke:


Wawu. Not it is not my controller. My Charge controller. Is a quality controller made by Renogy in the US so it is a quality and expensive product ke. This cannot even be right. I have a clamp meter and I have measured the DC Amp directly from the panel’s wire as well as the Volt. It is giving me exactly what the MPPT controller is giving with just a little loss. So it is not my controller

kristien4:
They are Jinko 580watts.. i bought them from Gennextechnologies

Please bosses.
I have a 60am cc.
Producing about 12 to 15smps currently.
Have 5x300 watts mix of poly and mono panels.
Plan to add 5 or 6 more 300w.
Can this be added to the cc on ground?
Thanks.

Drgreatone:

Running my top loader washing machine on it as i type. Advantage of the hybrid is u can oversize ur panels such that it powers ur load and still charge the battery which u sort of lose wit this pwm charger. I was goin to ask, whats the max panel input of ur pwm controller used? Looking like u connected ur 900watt panel to it directly?

Obnoxious2001:


Check your current cc max input PV. (This will tell us precisely)

But if I will speak from experience, it will work, but the cc will limit your output (i.e if your PV can generate above 60A, your cc will limit it to just 60a) this is if the cc has that type of protection

emmaniche:

Boss. Abeg see my cc config.

Obnoxious2001:

How many volts is yours system?
Current pv voltage

easyyoke:


Nice. It is Jinko 550w own I got from Foauni but my yield is just like 50% of what the panel should produce. Everybody is saying it is currently because of the weather. Are you still getting that 2730watt this period? Or your yield has dropped.

emmaniche:

No vex o, can u expansiate on the question.
Thanks.

Obnoxious2001:


The maximum PV your controller can accept is 3kw.

On your controller, how many volts does it show from the sun.

How many volts battery is it charging

emmaniche:

Can't provide values of the volts from the sun.

Its charging a 24v 🔋

Obnoxious2001:


Okay, for your current cc your I think max you can put in is 6* 300 (2s2p), anything above this, might limit its output.

This is not a professional view.
Besides you have 5panel,
So it's like 2s2p with 1 in parallel to 1
Or it's not in use at all

emmaniche:

When u say limit its out. Abeg clarify.
2s2p?

Obnoxious2001:


If your PV generated above 60A, your cc will only give out 60A

emmaniche:

Clear. Thanks boss.
The max I've ever gotten is 18amps on my current setup.
Can I add more panels to my current setup?

JoeSef0:
So basically
There's no implications to it if it's left that way?

ewizard1:

Won't like to argue then.

But dyou think you can always get the EXACT model number of every inverter mosfet?

Do you repair inverters? Cos I do and have confirmed it many times. You don't just swap in mosfet because they look alike, you look up their specs. If it matches in rating, NOTHING wouldn't make it work.

That's why every single of these devices have something called DATASHEET.

easyyoke:


My Jinko panel is clean. It is brand new. So no dust on it yet. Just 3days old and I have been taking the reading over the course of three days. Good shinning sunlight. Yet the max I am getting is 270w out of the Jinko 550W

Penuelseun:
I would suggest you get another mppt controller

bassdow:


So you're making a suggestion on replacing something this expensive without stating reason(s) why one should do so.

Doesn't even look like you've got a clear idea what you speak of to begin with.

na wa Ooo. You talk like say MPPT (even if na fake sef) na less than 5,000 naira
