Solar Charge controllers?
A charge controller usually has 3 terminals, solar panels, battery and
load. If i measure the amperage and voltage of each of the terminals,
the results i got was the amperage and voltage flowing through the
cable at that very instance?
Cables from the solar panels to the charge controllers mean the
charging state?
What about the cables from the charge controllers to the battery?
And also the cables from the charge controllers to the load?
Can someone clarify the amperage and voltage that i got in every
section that i mentioned above means...?
The results that i got from the battery and the load is about the
same. Why?
Thanks.
Okay, let's do this a bit at a time.
When the sun shines the solar panel will produce power, this is passed to both the battery and the load with the load taking preference. When enough power is generated to power the load, the excess is diverted to the battery to charge it. Under these conditions when you measure currents in the circuit you will find that the sum of the currents in the battery and load circuit will equal the solar panel current. Note that if the battery current is negative in value, this means that the sun cannot provide all the power for the load and the battery is supplimenting the solar panel output.
The cables from the charge controller to the battery carry current in both directions depending on the load at that time and the output of the solar panel, see the note above.
Cables from the charge controllers to the load carry current in one direction only, this current is supplied either from the solar panel or the battery.
Cables from the solar panel to the charge controller carry current in one direction only.
The results that i got from the battery and the load is about the
same. Why? Looking at the first parragraph and assuming the sun is producing enough power in the solar panel, your results indicate that half of the panel output is going to the load and half is being used to charge the battery, this is a very good position to be in.
BUT
If the ammeter reading in the battery line is negative, then half of the load power is being supplied by the solar panel and half from the battery, this is not a good position to be in as tha battery will eventually go flat.
If you want to study this circuit, you need ammeters in the battery line, the load line and the solar panel line, the battery line ammeter must be able to indicate a negative or positive current flow to show if the battery is being discharged or charged.
