Sizing the capacity of a solar charge controller is crucial for the optimal performance and longevity of your solar power system. The capacity is primarily determined by two main factors: the system voltage and the maximum current that the solar panels can
If a solar array has a voltage of 17V and the battery bank has 14V, the solar controller can only use 14V reducing the amount of power. With Pulse Width Modulation controllers, as the batteries approach their full charge, current to
To wire a solar charge controller, firstly, connect the battery to the controller, ensuring the positive and negative terminals are correctly matched. Next, connect the solar panel to the controller, again matching the terminals correctly. Always make sure everything is safely disconnected from power sources while working.
To select a properly sized solar charge controller, you first need to calculate the maximum current from your photovoltaic array using this formula: Max Array Amps = Total Max Panel Power (Watts) / Nominal Battery
Add up the total watts of solar panels and divide by either 14.4 for 12-volt systems 28.8 for 24 volts or 58.8 for 48-volt battery banks. This will give you maximum output amps from the controller. If you don''t want to waste

Most 30A charge controllers are designed to work with 12V and 24V batteries, but 48V batteries require a larger one. Charge controllers are measured in amps. The basic rule is the controller amp rating must be higher than the amps of the solar panels or solar array. The formula is: Solar panel watts / volts = amps + 20% = charge controller size
The PWM charge controller size must be 30 A x 1.25 = 37.5 A for such a system. We need to consider both the amperage and the voltage when matching the correct size charge controller to the system. See also: What A Solar Charge Controller Does (Explained)
