How do you charge these different battery packs?? Same inverter??

sharks776:


Wow 😲 this is huge, would love to see a picture of your power set up.
Are they all connected in parallel?

Trippledots:


You sure you are actually reading the recommendations and advices given?? Calm down and read them o

Hybrid600:
This is like my best thread on NL. The wealth of knowledge here is immeasurable. Thanks to everyone that contributes in one way or the other.

@swagifted
Where my Jos mango?

Edrizz:


Do you have the 80a

Price?

kristien4:
Between an ipower 5kva hyrid inverter... 4000w pv
And Powmr 6.2kva hybrid inverter...6500w pv which is better. Is Powmr a good product?

I have not made any comment here in years.......
How am I not going to make this an epistle....

Thanks for your wonderful contributions. I think you are right on this one. But not entirely 100%.
The OEM did not state the rating of the mppt tracker in their spec sheet. I strongly suspect that they chose to be silent on this for a reason. They know what they are doing.....
I did a couple of deye installations of recent in two different places. I had to put 8 units of original Canadian solar 650W panels on 6Kw deye inverter and I ran into a dilemma doing the job. All panels installed together in the same angle.
If I split the panels into 2 strings, the inverter will struggle to wakeup or run during the day. To make matters worse, if I choose to do the second string, I will have to run extra pair of 10mm cable over 40meters. At 5000naira/meter that is extra 200k.
I was very angry and furious with deye on why they choose to be silent over this very important matter.
Well.... i took matters into my own hands. I put all the 8 panels on one string and into one of the mppt tracker knowing fully well that I am not going to break any of the rules according to their spec sheet to avoid voiding the warranty.
Kw, voltage and current all slightly below spec rating even on a single string.
On commissioning, we were getting well over 100amps. In fact I had to limit the output current at some point to protect battery. Installation had been running for several months without any issue.
My conclusion is that the 7.8Kw norminal rating for a 6Kw deye is for the internal charge controller and not mppt/2 as i also previously thought. After all, they did not state this in their document anywhere.
Now... their could be reasons where you want to use only one mppt like in my case. Their will also be many reasons where I will want to use the 2 mppts like if I have enough panels, if cost of running cable for another string is no issue or if the installation is such that sun shines on one part of the roof in the morning and the other part later in the day and i need to take advantage of the two sides.
Hope this helps.

Based on specifications, what you experienced is normal.. it can output 6500w maximum.

13A x 500V on each tracker. Is 6500w
That's 120A charging at 48V norminal which is the maximum it can charge.

But don't expect it to output 6500 on both trackers to give 13kw.. it will simply throttle them to 3250w each and output 6500w.

That's why it's written maximum full Load 250V per tracker. So if you have like 13kw. The trackers will work at 250V /13A + 250V/13A which is 6500w

Just like Epever allows you to use 2 tracker as 1, or allow them to operate as independent 2 tracker, output is still limited to maximum output.

Good evening, please I want to start buying materials and keeping them instead of waiting to do it all at once.

Which should I buy first? I was thinking of the growatt SPF ES5000, then panels and batteries.

Which type of panels should I get and battery type too.

Any other recommendations are welcome, especially ways or materials that will not cost me a lot but still be able to work

Thanks

Buy them in this order: Inverter>Battery>Panels.

Reason: Inverter has a long shelf life, Batteries has a short shelf life, Keep them too long, they would sulphate or discharge beyond DOD, Panels will be exposed to breakage and other risks when you stock them.

Secondly, you can start using your Inverter & Battery when you grab the batteries and add Panels later.

Third is that the price fluctuations affects Inverters and Batteries more than Panels.

I hope this helps

They are the same family.

microgiant:


You are on the right path.

Buy inverter first, then Panels and Batteries last.

Experts on this thread have a unique way of answering questions, which seems odd to me.

dollarnaira:


Depends on type of batteries
Lithium generally has nothing to do with sulphation.

Hello Chief.
I'm curious. If batteries have short shelf life, how do manufacturers and sellers store them in their stock before sale which may take months?

ibietela2:


Thanks, which inverter brand do you recommend for a budget of 350 to 400k?

Dishtech:

200w is a 24V panels, with voltage between 31.5v to 36v. The best way to charge battery with pwm charge controller is to keep the panel voltage battery voltage to avoid power losses hence 80w-180w panels are recommended for a 12v system. But if the charge controller is mppt you are good to go.

jonescosmos:


Please do not store your Lithium Batteries for too long without trickle charging them from at max 3 months interval.
They might gradually deplete beyond DOD and you might need to jump start them and there are also chances that some of the cell might not operate as normal as should be after that.
Lithium Cell Warrantee does not cover this scenario.

PLEASE TAKE THIS SERIOUSLY

jonescosmos:


Any Good 3KW 24V Voltronic Based Inverter within your budget will be ok. Felicity, SAKO, SNRE, MUST, Ipower, etc, If you can up your Budget a little, Go for Growatt.

Powmr 60a for sale

ayo1984:


Do you have 80a

jonescosmos:


Usually they would factor in some months from Production to Shipping. This might take out 6 - 8 months shelf life for Flooded Batteries, 5-7 Months for Gel Batteries, 10-14 months for Lithium Batteries. So resellers have average Max of 6 Months or less to sell the battery.
This accounts to why they don't recommend you store them further than necessary.

abbeymighty:
Good day all,
Please did PowMr have office or repair center in Lagos?

Peterlove11:


Are the jinkos better placed than the longis in terms of orientation?......based on the numbers on the pix, it seems the jinkos are doing better in terms of generation

mctfopt:


Those two panels you mentioned have Isc of more than 11A each which will exceed the yeye 5000ES Growatt's maximum PV input current of 22A
