What Voltage Do Solar Panels Produce At Maximum Sunlight To Charge An Acid Battery Connected By A Charge Controller


Typical maximum system voltage in a photovoltaic solar panel gives about 18.5 to 20.8 volts peak output . This volt comes from a standard photovoltaic array system connected with 32 or 36 individual solar cells. This is enough to charge a standard 12v acid or lithium battery.

The technical specifications of the modules indicate a nominal voltage of 12V, but for a regular operation of the battery charger required about 16-17V.

Voltage at the operating point of the solar module with 36 elements to gather 1000 W / m2 and a temperature of 25°With about 17 In.

When the temperature rises, the voltage decreases, and when it decreases, it increases.

Modules with 72 elements have a rated voltage of 24V, at the point of maximum power â about 34V Suitable for charging 24V AB via PWM controller.

Modules with 60 or 48 elements are modules for MPPT controllers or network photovoltaic inverters .

Connect The 12v Battery To The Solar Charge Controller

Connecting a battery to a solar charge controller requires wires, wire connectors, and an inline fuse.

You can use your own wire and connectors, or you can buy some to make the process a little easier. I ended up buying something called the NOCO GC018. Its a 12V plug adapter that comes with an inline fuse and ring terminals the right kind for my 12V battery.

To start, I cut the 12V plug off the NOCO GC018 with my wire cutter.

Then I just pulled the wires apart a little bit and stripped the ends.

Now my wires are ready. I can connect them to the battery terminals using the ring terminals. And I can connect them to the charge controller terminals using a screwdriver.

So thats what I did:

I first connected the positive and negative wires to their respective battery terminals. Like so:

Then I used a screwdriver to connect the stripped wire ends to the charge controllers battery terminals. My controllers terminals have a battery icon on them, as well as a plus and minus, to help me know where each wire goes.

When all the wires were connected, my charge controller turned on to indicate that it was properly connected to the 12V battery.

Consult your charge controllers manual for instructions on how to program it for your battery type. Mine defaults to sealed lead acid batteries, which is the battery type I was using.

How To Use A Solar Battery Charger

Solar Battery Charger/Maintainer from Suner Power

This will vary from device to device, but the most basic way to use it is as follows. When youre not using it to provide power to your battery, you leave the solar panel affixed to a window front, rear, or side where it can gather power from sunlight. Once your battery dies, you can attach it directly to the battery or plug it into a cigarette lighter. Either way, the stored energy will be used to jump the battery and either charge it or maintain the power level.
