How?
One panel to one battery via controller?
Two panels to one battery via controller?
Two panels to three batteries via controller?
etc
Re: Solar Energy, A Complement To FTA by SolnergyPower: 10:17pm On Oct 12, 2019
You can connect two or more panels together to charge your battery or batteries via the charge controller.

You'll need to consider factors like:

a. Solar panels specifications
b. Specifications of your charge controller
c. Inverter size
d. Battery bank size
e. Load
f. Weather

Etc.

Given the enclosed specs, can I connect the panel to the battery via the controller? I ask because battery is 12v, controller is 12/24v and panel is 18v. I know battery and controller are compatible but panel?
My question:

1.If a controller says 12v/24v, does it mean it can take voltages that are between 12 volts and 24volts(thus take 18volts) or it means it will only take either 12volts or 24volts. Thanks.

Picture is Panel specs and PWM controller(40a)specs.

The PV Vmp is 17.5v, you are good to go. Most PWM can take up to Vmp of 24v for a 12v battery system. The PV opencircuit voltage does not necessarily have to match 12v or 24v for either of the two.

I just completed the wiring for the installation; lights only for now(5×5watts DC bulbs) since inverter is not presently available. With the above connection, how long(hours) will it take the panel to charge two of the battery above(connected in parallel) to be fully charged at 50% dod if sunhour is (8hrs)9am to 5pm?
Re: Solar Energy, A Complement To FTA by SolnergyPower: 4:30pm On Oct 13, 2019
1. Solar charge controllers operate in a range to voltage to charge batteries. That's why the current produced at different times during the day from the panels is not even. Most PWM solar charge controllers rated 12/24V can take up to 50V from the solar panels.

2. You can connect two panels of that your 17.5V in series to your CC and it'll still work very fine.

I have a question. If I connect the panels in series, it becomes 24v which the cc can accommodate. But my inverter is 12v.
If 24v enters the cc, will the cc change it to 12v that is the inverter intake?

My understanding is that since my inverter is 12v, I must ensure everything stays 12v. So no series connection as that is adding voltage.


I ask this question because I have another 600watts(150watts×4) panels wired in parallel to a 12v/24v 60a pwm cc because of my 12v inverter.

So will 24v(12v+12v series string connection) inputed to 12v/24v convert and output as12v for 12v inverter?

*Yes using a PWM CC, it will make use of 12V (out of the 24V at intake). The other 12V is simply discarded (as losses).*

My understanding is that since my inverter is 12v, I must ensure everything stays 12v. So no series connection as that is adding voltage.

Yes, stay at 12V for everything.

Yes it will convert and output 12v for 12v Inverter but at a huge cost of power losses.

Thank you. You have solved a source of headache. Well I shall stay with my 12v till I am able to get 24v inverter.

There's no such thing as wiring the panels to stay within a 12V or 24V range. This is why the solar charge controller has a voltage input far above the voltage of the battery bank. A CC of 12/24V can take up to 50V. So even if your system is 12V, you can still input up to 50V from your panels.

There's what we commonly refer to in this thread as voltage headroom. The higher the voltage from the panel, the better as long as it's within the tolerance level of your charge controller.

The panel don't produce the same voltage throughout the whole day, as the sun increases, the voltage increases and more harvest is generated. So if you've a 12V battery bank setup and your panel is feeding in 17.5V, any slight drop in voltage from the panel, you won't receive any current unlike when you've 40V from the panel, even if the voltage drops, you'll still receive little current.

For the 4 x 150W, hook them 2S1P.

very very untrue, my brother!.
you forget about pwm and mppt CC?, I wonder who clicked like on that post of yours. lipsrsealed

pwm, you should try and stick to system voltage, ie 12v panel, 12v CC, 12V INVERTER
MPPT, YOU ONLY LIMITING FACTOR IS CC max input voltage . most 48v mppt cc have 150v as max, while most 24v have 60v to 100v though with experience, you would know the sweet spot of various CC

ok, maybe you should hv added personal opinion to the advice, you gave the fellow.
pwm cc will waste any excess energy..if you feed it a higher voltage than specified, mppt will not, but would rather convert the excess voltage to current. if they are all the same, why do u think the mppt is more expensive?

Are you sure of this your number 2? We are dealing with a pwm charge controller and not an mppt.

I think you are wrong. If they are 2 panels and the system voltage is 12v the panels have to be connected in parallel not series.

Oga, I yield up to 20A instantaneously from 4 panels of 150W connected in 2S1P in a 12V setup.

Forget what you read in the books and do the experiment.

Besides, the manufacturer that rated Max PV input of 12/24V PWM to be 50V isn't stupid

Are we really having this discussion?

@TopMost11 if you want to maximise your yield from a PWM CC please keep your array voltage as close to your battery voltage as possible.

As for "forget what you read in the books", i will not do that if I were you. Let the theory be your guide in experimenting.
