Inverter
A device that converts direct current (DC) electricity from solar panels into alternating current (AC) electricity used by your home.
Why It Matters
The inverter is the "brain" of your system. Its efficiency (typically 96-99%) determines how much of the DC power from panels actually becomes usable AC power.

Microinverter
A small inverter attached to each solar panel, allowing independent operation and optimization of each panel.
String Inverter
A central inverter that connects to multiple solar panels in series (strings). Less expensive than microinverters but less flexible.
DC (Direct Current)
Electricity that flows in one direction. Solar panels produce DC power, which must be converted to AC for home use.
AC (Alternating Current)
Electricity that periodically reverses direction. Standard household electricity in the US is 120/240V AC.
