I don't think your cc can handle the current that the panel can produce for a 12v system(about 60amp simultaneous current on a good day) How many batteries do you have by the way? You will be better off with a 24v system, but if you want to go ahead, you can go with a 2s3p configuration

tchijioke:

@Penuelseun thanks for your prompt response.
I have 3pcs of 12v 200amps battery.
I know a 24v system would do me a lot of good... But the challenge at the moment is getting a 24v inverter to replace the existing 12v...not yet ready for the expense. I just bought the panels and need some financial break before tackling the inverter upgrade head-on.
Once again thanks, I sincerely appreciate your contribution.

it is complicated because the ones in the link are all in parallel but the one in the shared picture has both series and parallel connection.

Six 200watts panels, three 200ah batteries. What sort of controller are your using?

From advise given me when I asked an almost similar question, if he has a mppt controller whose capacity can accommodate the load, cant he go series with the panels and push it into the 12v inverter. My only concern is will the panels take the three batteries home ie charge them to full.
Alternatively, can he connect 4 of the panels and leave two in storage till he gets 24v inverter? But again, batteries will not be charged fully.

dragnet:

If your system is 12V, then your only option is to parallel the batteries and same with the panels, the next question should be "all 3 batteries?" or "all six panels?".

Pls @Penuelseun can you sketch a schematic of the 2s3p panel setup.
Thanks in advance.

tchijioke:

Thanks for the technical support.
With this configuration the output should be 48v 15.33amps...its within the controllers range... My other concern is that the controllers max watt for a 12v bank is 550watt, won't it be an issue since that is the only parameter that seems out of place. Thanks

Penuelseun:
another option you have is to buy another pwm cc(it's cheap) to use together with the mppt, then split your panels into two groups of three panels each on the two controllers, your panels should all be parallel in the two options pending when you go the 24v route

Warm greetings to all the gurus that's giving life to this thread...
Pls I need your input to get the best possible setup with the available items:
1. 40amps mppt charge controller. Find detailed spec in pix attached
2. 6pcs 200watts solar Panels. Find detailed spec in pix attached.
Spec: Vpm =36.21v, Ipm=5.11amp
3. 12v battery bank already installed

QST: what would be the best panel connection/arrangement for optimal performance.
Thanks in advance for your responses.

Penuelseun:
With the configuration, the panel output will be around 70v 30amps, if your cc mppt function come into play the you should get like 65amps at 14.4vdc which your controller cannot handle, going the 24v route is your best option now

dragnet:

from the image you posted here, your CC can't accommodate more than two panels in series for your 12V system, you can't even go to three considering the voltage limit. So just forget all the permutations and combination till your system is 24V.

What you can do is to buy two cheap pwm, then split your panels into two groups, one for each pwm.

earthrealm:


Errrm..this might not be a good idea, using mppt and pwm cc on same bank, it would be worse if they r different makes.
There are many cheap mppt cc in the market now.
Like the powmr, about 70 dollars on AliExpress. You can get 2 units of that model...they would still be useful to you in the future...or u buy 2 ultra cheap pwm as well, if you insist on pwm cc

I need a solar setup to carry the following loads

Xbox gaming console.
Tv decoder
2 -40inch tv (dont mind using 1 at a time).
Fan
Bulbs
Deep freezer maybe

Please mention me on any of my topics and we will follow up from there.

Pylontech batteries with Axpert vmiii inverter. This Axpert talks to the pylontech via rs485 so settings are automatic. The Pylontechs will work with any inverter that allows you set bulk and float voltages. Each battery has a built in BMS that disconnects on the set voltage to protect the batteries.
