The solar energy is collected and stored in the batteries as a DC current. The Xantrex inverter changes the DC (direct current) to AC (alternating current) for use in standard household appliances. The controller box manages the charging of the batteries from the solar panels to the batteries.

The Batteries are 6 volt Rolls brand. There are 2 rows of 4 batteries wired as a series in parallel. This gives us a 24 volt system. 4 batteries x 6 volts = 24 volt

There is also a 6,500m KW Honda backup generator just in case!
