I never get above 300w from my 2 PCs if 555w jinko s. 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?

HeavenlyBang:


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

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

You just need to not overload your s 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.

PWM or MPPT?

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

13.8V is too close to your battery voltage. It will take time to fully charge, but it will make your batteries last long.
increase to 14V ~ 14.2V, you need around 1V difference for optimal charging.
51.2V system has an advantage where you can set 3.45V per cell and still charge well because it's 16s.

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 s? Mind you, PowMr cannot go beyond 80v at 12v. My pv is 300w ×2 and the result is very very good.

How did you arrive at the conclusion that you don't get above 300W from the 2 pcs of 555w jinko s?

What capacity if 12v lithium battery do you use? You could also try using the default powmr settings for lithium battery.

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 is 49.5v

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

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

Power draw. The more power you draw from your s, the higher the temperature gets, and conversely the lower the voltage they can supply.

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.

thank you boss. My system charges but I don't get as much watts from the s. 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.

Allem:

Have you tried turning on load to see if output ramps up? Something like a 1hp inverter AC when the sun is out.

Have you checked your charge controller settings? Your charging current may be limited to something low.

Mind you, that charge controller in a 12v setup is limited to just 700w pv input. So you'll never be getting your 1110w rated output anyway.

Good evening

I have felicity 5kva 24v inverter connected to 4 300w felicity 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 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

Just coming in BUT wanna inform you that your Charge Controller would never give you close to the worth of your Solar s. Now have you bothered checking if your Solar s are properly connected to the charge Controller ?

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.

See eh, no matter how much people advocate for green Energy, there would still be wide use of Fossil FUEL abi shey na SOlar s go move Battle Tanks for war Front, abi shey na green Energy dem go take launch rockets and missiles.

By the way, those Charge Controllers you mentioned, remains the very best. Unfortunately, the market has been filled with so much Nonsense that except you really know what you want, and insist on it, you could spend so much and still be sold noneSense.
All my charge Controllers na epEver though have used MorningStar before but had to sell to a client. That thing cost no be small

All in One DeskTop Computers have existed for several years now YET adoption has remained super slow. e get why

The Taste of the Porridge is in the Eating. Most either can't afford them, or are yet to experience it.

I'm not an iPhone fan but a Sony fan so much that from my first Phone (right when they still were sonyEricsson) till now they're now called Sony.
As in, I never change am. I see people having Techno phones or the likes with 20MP camera but my own small phone with less than 10MP still sharp them own.

Also if you're not used to using quality phones, and asked to use inFinix, Tecno, LG, etc, the hanging go fit make you break am. As in their s really are patient. Phone go get SPECs with big numbers only on paper. 6GB ram go dey operate like an overLoaded 1GB ram

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 s pls I'm using grid to charge as we still get about 12 hours of light daily

Anyone interested hit me up via siggy

yea for now. Hopefully Prices don't quadruple when you finally ready to get one. I don hear this your talk plenty times.
Use Solar for 1-week and you would wonder how you've been able to survive all these years.

loluskysat:


@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.

I still believe it's not that adviceAble especially going by the kinda load you using. That's because You reducing the life span of the inverter.

There's a reason electric Bulbs burnt out when NEPA supplies high current; BUT do you also know that if the HIGH current was only for a few seconds, the bulb might not BURN out but surely it's life span must reduce.
Balloons expand before bursting. Several small capacitors don spoil for one of my Computer Monitors, yet it's still works like nothing happened.

Now let me ask,
1. how many batteries are you using ?
2. how many Solar s ?

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 s installed. I saw a tiktok video where someone said that a 100 amps gel battery won't last for more than 6 months

Please get at least 200AH battery. Because small time, you go add DVD player, sound system, etc; and the poor thing go continue dey adjust like Nigerians.

Also ensure you go for average to quality brands else you would be changing batteries almost yearly

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.

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

easyyoke:
Abeg make una help me o. Is it normal for a 550W of 48V VOC to drop to as low as 26v when under load in proper sunlight.

Do you mind telling us how you read the voltage to conclude it's 26volts ? probably it's displayed on the chargeController or you read from battery terminals or what exactly
