Off-grid Systems make up a very small proportion of Solar Energy systems installed today. They are typically used when access to the electric utility grid is not available or when full energy indepence is desired.
For these systems, DC power is sent to a battery charge controller which charges the batteries and prevents over charging. DC power from the PV panels and batteries is sent to either DC circuits in the house or to an inverter which converts the DC electricity to AC electricity. The AC electricity is sent to the AC circuits in the house.
Batteries are the heart of this type of system. If the battery bank is not large enough to compensate for periods without sunshine, the house will not have electricity.
Typically some other type of backup system (such as fossil fuel generators or wind generator) is included in this type of system as well.
This system is the most complicated and requires the most maintenance of the three major types of Solar Energy Sytems.
