Selecting the Right Size Controller To size a solar charge controller, take the total watts of your solar array and divide it by the voltage of your battery bank, then multiply by a safety factor of 1.25. This calculation will give you the output current of the charge controller.
Knowing the size of the “solar charger needed” largely depends on your battery size and desired charging speed. Assuming optimal sunlight conditions (around 5 hours of peak sunlight), a 100W solar panel can generate around 500Wh per day.
Depending on the number and power of the solar panels to be paired with the number and voltage of the battery bank, a selection of the best size charge controller can be made. Charge controllers are rated according to amperage.
First, you’ll connect the battery to the controller. Next, connect your solar panel to the charge controller. This allows for safe and efficient transfer of power. Finally, position your panel to receive as much sunlight as possible. The more sunlight it gets, the faster your battery will charge.
They can supply power to larger devices such as laptop computers and camping fridges. Often used to maintain car batteries, these are designed to deliver a small, steady power stream. They usually range from 1.5 to 5 watts. Choosing the right solar battery charger boils down to understanding your battery’s needs and output of your solar charger.
If we had 3 100-watt solar panels, the equation would be 300/12 = 25 amp, so we would suggest getting a 30 amp charge controller. So, even though the rough estimates of the size of the charge controller for a 100-watt solar panel may be close enough to our calculations, it is safer for you to work out the size as we did, and not just guess.
