Where can one get yingli?

anjilgreat:


Good morning sir, do you have 300W monocrystalline Canadian solar panels in stock, and how much?

kiekie1:


Thanks for the patronage Ma ! God bless you

ojtech8291:
I have 6 units of 275W panels, Rated voltage 30.9V, Rated current 8.91A, VOC 38.8V, SCC 9.47A and Max system voltage 1000V with two different CC 12/24/60A VMax is 70V, while the other is 24/48/40A Vmax 100V. Which of the controller is the best to handle 6 panels and at what configuration of the array, 2S3p or 3S2P?

Your Mpp inverter, does it charge with the inverter turned off?.

ojeysky:


I will use the one rated 70v and do 2s3p

ojtech8291:
I hope the Voc of the panel will not go against the Vamx of the CC at a peak sun?

dapsyra:


The only safe option is to use the 100v CC in a 2S3P array as 3S2P arrangement will also exceed the Vmax for the CC




If you use 2S3P format, the array VOC might go above the 70v Vmax the CC can tolerate especially in cool days. This is a sure recipe for disaster.

ojtech8291:

ojtech8291:
Thank you but remember that the one with Vmax 100V is 40A. Will the 2S3P not going above the CC current?

ojtech8291:
Thank you but remember that the one with Vmax 100V is 40A. Will the 2S3P not going above the CC current? I hate this kind of CC that won't allow manipulations. The last thing to do is reduce the panels to 4 units and look for another 2 units to hook up the leftover. Any suggestions?

dapsyra:


The SCC of your panel is 9.47A . 3S will produce a theoretical maximum current of about 28.4A. This is still well below the CC rated capacity of 40A.

Even if the current attempts to go above 40A, most well built CC will clamp it at the rated value.

I don't think 2S will ever hit 70v, it will only always be close no matter the cold start. I actually have a friend that runs 300w (2s2p) on a 70v CC and that is the scenario that has played out thus far.

Your Mpp inverter, does it charge with the inverter turned off?.

@ house, my 4yr old luminous FLA, have started need frequent watering, before it could go 4 to 8wks b4 needing water, now its about 2 to 4wks. And some cells need more water than others....sg readings are fairly same, apart from a few rougue cells. Ie out of the 6 cells in a battery, 1 or 2 may need 70cl of water.. another 2 cells 30cl, and the rest needing only 10cl.

My inverter charge setpoints are 14.5 for absorb and 13.8v for float, same for the CC that i introduced 4 wks ago.

Lil research on the web , say as fla batts age, they need more watering, but mine appears to be on the extreme.
Am thinking of reducing the absorb & float voltage to 14.1v and 13.6v respectively.

I know am 1 of the few sturbborn peeps still using FLA in this time of Lipo4 batts and all, but if you got any tips from your fla days, kindly help me.

ojeysky:


I don't think it will get to that level which will be 35v

ojtech8291:
2S is above 35V. 35V is the waking up voltage for my own. Sometimes it will reach 69VDC.

ojeysky:


I meant that it will be 35v per Panel, each of those panels with that rating won't do 35v, it will only always be close to it. Including in the morning.

LFP users are like less than 5% of total users out there in the real world

Have you checked for cracks or a leak on the case of the battery that needs more topping?

ojtech8291:
Since this place is quiet let drop another question.

Can One HA02 handle 4S5P battery bank?

earthrealm:


hmmm, i differ o
the yingli i posted abobe, i have them in 3s2p, and it has hit 104v on some cold poor sunlight days

The Xbox one S apparently consumes 80w and below. That to me is not energy hungry. The average laptop takes about 65 watts while charging and in use.

Seems a fair deal. Happy sales.

brainhack:
1.5KVA Inverter + 200 mah batteries (x 2) for sale (used - over 2 years old but still in top like-new condition cuz I never connected heavy appliances to it). I called a technician to test it recently, yes - still in top condition.

The last time I tested it myself with;
1) 40” Samsung Curve TV + Fan + X Box One S = Lasted about 13 hours (Note: 13 straight hours of gaming & X Box One S is an energy hungry device monster).
2) Just lights + Fan + charging Laptop + phones = Lasted over 30 hours.

You don’t have to take my word for it, bring your technician along for testing.

I don’t need it again cuz I am moving to an apartment building with 24 hours guaranteed electricity.

Dam5reey:


How come you got answers to this Question

What is your system Voltage?

I will assume 24V as common factor in both CC

If your system is 24V, then you cannot use the 40A controller
(6* 275w is 1650w ) 1650 watts / 24 is 68.75A

So you have only one option left.. ✅

Better still use Both ✅

In willing to take the inverter only from you ASAP payment.
What' do you say?
The batt3 should be an easy sale but sadly O don't need it.
