A 150Ah battery can deliver 150 amps of current for one hour or 15 amps for 10 hours, depending on the load. Battery Voltage (V): The voltage of the battery affects the total energy it can store. Common battery voltages include 12V, 24V, and 48V. For a 12V battery, the total energy capacity is calculated as: Total Energy (Wh)=Battery Capacity (Ah)×Battery …
This calculation will give you the output current of the charge controller. For example, a 1000W solar array divided by a 24V battery bank equals 41.6A. Applying the safety factor, 41.6A x 1.25 = 52A. Therefore, you need a charge controller rated at least 52A.
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.
This gadget regulates the power flow between the solar panel and the battery, ensuring that the battery remains at a consistent state of charge. Since solar panels produce different amounts of electricity depending on factors such as weather conditions, the charge controller ensures that excess power doesn't damage the batteries.
• Certain low-voltage appliances must be connected directly to the battery. • The charge controller should always be mounted close to the battery since precise measurement of the battery voltage is an important part of the functions of a solar charge controller.
MPPT solar charge controllers are rated in amps (Output Current). To select a charge controller, you’ll need to calculate the maximum amount of current (in Amps) that the MPPT should be able to output.
Solar panels output more than their nominal voltage. For example, a 12v solar panel might put out up to 19 volts. While a 12v battery can take up to 14 or 15 volts when charging, 19 volts is simply too much and could lead to damage from overcharging. Solar charge controllers aren’t an optional component that delivers increased efficiency.
