Inverters transform the DC current from the Solar Panels into AC current to power most household appliances. The numbers on the top of the inverter show the power in and the power out.

A Phoenix Inverter 12/250 is for a 12V system and creates 250W of AC power, whereas a 24/800 is for 24V in and 800W out.
