In contrast, when you use a solar panel
directly, the output voltage depends on the solar
conditions, and it’s often higher than what your
devices need. When all your appliances run on
the same voltage, for example, 12V, you install a
DC-DC converter which accepts a variable input
voltage and produces the desired output voltage.
Next, you split the power (Figure
L
). When your
devices run on different voltages, first split power
and then put a DC-DC converter in every circuit.
Divide power again if you want a second output
with the same output voltage.
If your solar system has a battery and charge
controller, and ...
