Off-Grid Solar Power Solutions:
How Off Grid Solar System works:
Off Grid System : This involves getting power from solar power
with an optional generator as backup. See the diagram below.
Instead of a connection to the grid, there can be backup power
from a generator for when there are too many cloudy days in a row.
Optionally the generator can be started and stopped automatically
based on the battery voltage. In the diagram below it is a feature
of the inverter.
If your inverter doesn't have this feature, separate automatic
generator starter units are available. Automatically doing this is
better than having to run out and start the generator manually
when the batteries get too low for two reasons: convenience and
you don't want your batteries to go below 50% (without an
automatic starter, you'd have to constantly be checking the
battery voltage.) As an aside, the diagram below also shows a
separate display and control unit, often available depending on
the manufacturer of the charge controller and inverter.

The following photos show a typical system. Most of the wires have
been run behind the wall and enter the components from their backs
to prevent someone from accidentally hurting themselves. You'll
also notice lightning arresters in the photo on the left. These
protect the various components from lightning strikes. If
lightning hits a solar panel then the very powerful electricity
from the lightning could travel along the wires going between the
solar panels and the charge controller and damage the charge
controller. For this reason a DC lightning arrester is connected
to that wiring and is shown at the bottom of the photo. Similarly
there are AC lightning arresters used in case lightning strikes
the generator or the wires coming from the generator and in case
lightning strikes the household wiring.
