The inverter is the 2nd most important component of your
system, after the solar panels themselves.
They convert
the electricity generated by your panels:
Inverters are used to transform the DC
electricity produced
by your solar energy system into the alternating current
(AC) electricity commonly used in most homes and business
for virtually everything that uses electricity (lighting,
appliances, electronics, etc.).
An inverter takes the electricity from the solar modules
and synchronizes it with the utility AC electricity so that
your electricity is of the exact same quality as the utility.
This also
allows you to sell electricity back to the grid, since
your electricity is made compatible with the grid by the
inverter.
Most inverters are made to work with the standard grid-tied
system without batteries:
But there are also some inverters available
to work with battery back systems. These dual use inverters
(the bottom image on the right) often include
a battery charger, which automatically maintains the charging
status of your batteries so there are always ready for
a blackout or emergency situation.
