Have experienced this too. It's a pretty funny time for solar panels, since irradiance is incredible but the heat negatively affects it.

For example, this afternoon my panels were at 50°C, which is insane. At such temperatures, I probably wouldn't be able to draw more than 88% of my panel's rated output even though sun was blasting.

You just need to not overload your panels this period, I guess. Around 75% capacity should be fine (easily doable because sun is out); if you go much higher than that, temperatures climb, voltage drops, and suddenly you're momentarily getting lower voltage than your inverter needs to run.

I never get above 300w from my 2 PCs if 555w jinko panels. My system is 12v lipo4 ba3 don't know if the 12v is the cause. I amusing powmr 60a cc set at 13.8 for absorbed. Any things to getting a better watts?

PWM or MPPT?

Mppt POWMr

Where is Ur panel facing? N,E, S or W[b]facing S[/b]
How are d panels connected? Series or parallel------- parallel
What's d distance between Ur panel n d CC? Ie what s the length of d cable used to connect them. 7m
What type of cable was used? DC or normal electrical cable. DC N wat guage.6mm
What model of powmr mppt do U AV. I don't want to assume it's d common 1 around.will attach pix

You have been told to change from 13.7 to 14.1. Let your pv face the direction of any dstv dish around you. Did u series or parallel ur panels? Mind you, PowMr cannot go beyond 80v at 12v. My pv is 300w ×2 and the result is very very good.

Allem:
Thank you very much. My supplier said I should leave it at 13.8v. I no won void warranty, facing the direction of dstv, that will be East. Mine is facing south. They are parallel because the voc of the panel is 49.5v

dollarnaira:


Your supplier?
Bro 14.1v settings has nothing to do with warranty. Is the supplier here? Your supplier is wrong.

Allem:
Thank you boss. nothing to do with warranty On the batteries?

easyyoke:


Sorry, what do you mean by the statement “You just need not to overload your panels this period”. How does one overload solar panels. I dont seem to understand that part

HeavenlyBang:

I don't see why 13.8v wouldn't be enough to charge your battery.

My 24v battery bulk-charges at 27.2v and is perfectly fine.

dollarnaira:


Your supplier?
Bro 14.1v settings has nothing to do with warranty. Is the supplier here? Your supplier is wrong.

Allem:
thank you boss. My system charges but I don't get as much watts from the panels. I get around 300w

.. 13.8V not to void Warranty.. who did to us..
I have said it, that it is to cover flaws.. but many no wan hear.

Good evening

I have felicity 5kva 24v inverter connected to 4 300w felicity panel and 60A charger controller, 2 200 batteries

System have being working fine until fews days ago, i noticed inverter is charging and working fine with nepa only

It seems panel is not charging it at all ( see screen shot)

Is my charge controller bad? If yes should i sti buy same charge controller or mttp

Kindly help

If you follow trends, you'll see that it's here already and would be mainstream in the nearest future.

This thread started in 2010. In those days morningstar,epever,midnight, 150V MPPT cc were the standard. After a while morningstar introduced the 600V expensive version.
Lithium is making serious in road into Nigeria just years after the first group buy here.
When hybrid started, the adoption was slow. And the argument about ease of replacement was true but not anymore. There are as many hybrid as there are standalone in Nigeria. And in some clime, hybrid deployment far exceeds standalone. I think it's cost and knowledge gap that is holding Nigeria back.

I see same argument of ease of replacement against all-in-one system.

Hi guys
Good evening

I need a very good solar installer/engineer around Ojodu Berger Lagos.
I have a 2.5 Kva smarten inverter down
2 star plus battery down as well

Installer will tell me other items to get and I pay for your services. No panels pls I'm using grid to charge as we still get about 12 hours of light daily

Anyone interested hit me up via siggy

@ISJ: I'm a realist and not one of this textbook theorist. I test things and obtain the actual performance. For the 1000w inverter, we use it regularly to cook, but we use only one plate at a time and without any other devise on. The spec of the electric cooker is 2000w. We also use the same inverter to pump water using our 1hp pump. See, there is nothing wrong in using a device up to its rated capacity. They are actually designed to handle that rated capacity without problem and that is why it's stated, except if the device is fake or substandard.

Gr8teejay:
Good evening everyone. I'm looking to power a single room with 3 bulbs at most, one rechargeable fan and one tv. Do you think it will be okay to buy a 100ah battery? I already have 2 200w panels installed. I saw a tiktok video where someone said that a 100 amps gel battery won't last for more than 6 months

loluskysat:


@TechGeek77. How do you know if there is a big or a small plate? You just want to comment.
@Peterlove11: Hope you're clear about the inverter now.

easyyoke:
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.

bassdow:
Probably because most (if not all) hotPlates having 2 sides are composed of big and small.
