Inverter: A stand-alone solar electric system
consists of 4 basic parts:
The photovoltaic panels make DC
electricity, which is fed to the charge controller. The controller feeds the
current to the batteries at a regulated rate. The batteries store electricity
for when it is needed and then sends it to an inverter. An inverter is an electronic device which takes the direct
current from the batteries and changes it to alternating current (AC). Most
households run on AC because AC wiring is cheaper and somewhat safer than DC
wiring. Inverters are made to convert from 12, 24, 48,
225 volts DC to 120 or 240 AC. The AC output of inverters is either a
modified sine wave or true sine wave. Most residential systems use modified
sine wave inverters, which are somewhat less expensive.
