4 x 555 watts panels. And the distance is about 20 metres

Ur panels sud be joined in series cos of ur Inverter type and that wud keep ur amps same. I'd pick a 6mm for ease of expansion/upgrade later

Dam5reey:


seems you consulted a Kazeem, using Size of panel to determine the cable size.

Cable are sized based on VMP, IMP and distance.

Lol. It wasn't him who said that though but one of his boys but their boss said 10mm is what I need. Maybe it's because of the distance. About 25 meters to the inverter location.

The distance is 25m. Won't that be a problem?

jonescosmos:


Please I need your capacity test result on the Blue Carbon 15KWh batteries. I would also suggest you don't run it for too long before attaching the second unit. Because of INTERNAL RESISITANCE wahala.

Thank you

This is a high voltage inverter, as such all the panels should be connected in series.

A 4mm² cable is ok (at most 6mm²) the 10mm² is unnecessary.

Sapiosexuality:
High or Low? Attached is a photo of the specifications. And I'm yet to connect the panels so can't tell if it will be series or parallel.

Thanks Boss.

Checked mine and saw 1456kwh.

Didn't know I've joined the MWh peeps.

Congratulations

You will loose more with more cross-section in relation to distance bro.

Do this when you have the time: Get a 12V Okada Battery, cut a 30 meters of 4mm PV cable, use it to power a 12V Okada bulb. Do same for a 10mm cable, same length, Use a lumen tester or use your eyes to test the brightness of the bulb, come back and tell us with which of the cables was the bult brighter.

I did this experiment months ago.
I used an app to measure the lumen.
Ethernet cable vs regular flexible speak wire.
Difference was clear as I did roughly 4yrd (3.6m). Cable size and type matter. However, good cable goes beyond large bristles, quality matters too.

Thanks. I'd be going with 6mm². But in what situation can one use 10mm²?

Gone are those days when the only option was PWM controllers where more current is pushed, also going are those 100V Charge controller limits. where you need more current around 30A hence you need thicker cable.

An advantage to Hybrid with High Voc PV input is saving the cost of cabling compared to low VOC or PWM controllers.
In essence, the knowledge you are seeking is of the past, High VOC input requires less current usually under 20A

You are right. Since he will be connecting all in series, his imp might not even be up to 14amps. So 4mm² is his best bet.

@Sapiosexuality You can check the image below for your likely voltage drop.

R = (ρL) / A

You're better off not listening to this guy (if it's not you lol )
Same guy that said MPPTs are waste of money and PWMs do exactly the same thing as MPPTs;
He didn't even understand the physics behind excess voltage conversion and said it was a marketing scam.
Run ooooo!!!!

Annoying, he calls himself the solar "god".
They were correcting him and he was still arguing.

Definitely High Voltage. Your PV Breaker and Fuse should be rated 16A 500V DC and your PV Cable should be 4mm MAX

What the guy is saying is the truth, i have personally been burnt , by one of those dealers infact the number one he mentioned.

These alaba dealers are terrible, i bought an inverter from him, i requested for the inverter after sale service center, he told me if anything happens within the warranty period bring it back to him for free repair. Under 2 months inverter failed, took it him , 6 months later no inverter.

Waiting for parts story started , he will pretend has if he is on a call to china requesting for your parts.

I later found out the repair center actually are his boys at the back of his shop.
What they do is wait for customers to bring in their inverter , now you that just brought your inverter in today will be placed on a waiting list, the parts from your inverter brought in today will be used to repair another customer inverter brought in months before yours. The cycle will continue like that. The union in alaba is the most useless of all, go an complain about any dealer they will turn around and support their own....

Nawa.

I rather buy inverter from direct dealer or seller from here e.g. Zeestone99 than buy from Alaba.

The above is likely to resolve issues just to protect their names.

jonescosmos:


10mm PV Cables for such a small unit? Honestly? Why do this?. You will loos energy bro.
The most practical wire for solar panels is PV1-F 750V-1000V Anti-Stretch Shielded Outdoor solar cable, this cable is most common in 4mm2 and 6mm2. A very rough rule of thumb is for arrays of less than 20A can use 4mm2, and 20A or larger should use 6mm2. If a larger size is required, it is recommended to run twice from the array to the solar controller.

Irrespective of the length?

Good day house please i need a recommendation for a good brand new solar panel brand of 400-450w. Jinko and the co are too bulky to install on a 2 story building. Thanks

What do you mean by bulky?

Trippledots:


The whole gamut.

where exactly chairman, are you guys present in abuja?

ojeysky:
280AH brand new Eve lifepo4 cells @140k(minimum 8 units but can give discount if buying bulk)
320A peak and 300A peak ANT smart BMS also available 120k and 100k each respectively

Still available

Please house how reliable is xtrapower mppt solar charge controller

Greetings great minds

I have this small set up of 160 watt panel to 100amps battery on my farm for lightening

I want to ask if it's safe to add an 100 watt panel to the 160 watt panel, both are 12v or I get another 200 watt to complement the 160watt for quick charge

The 100 watt has been idle on the farm for a while
