A
Alternating Current (AC)
Expressed as a sine wave, the current of AC passes through zero when it changes direction, which makes it a safer electrical current.

ITC
(Investment Tax Credit) Federal Tax Credit that is associated with installing solar on your home. Currently valued at 26% of solar system purchase, given in the form of a tax credit towards your tax liability. Tax credit for homeowners is slated to step down year over year until it reaches 0% in 2024. It is regarded as the most significant financial incentive for solar in the U.S.

PV Inverter
PV inverters were originally developed to convert direct current (DC) generated by PV panels to alternating current (AC) for use in the home or to feed into the grid. One of the most common types of inverters is a string inverter, which performs both conversion and MPPT at the string level.
Standard string inverters offer limited monitoring possibilities, create energy losses, limit design flexibility, and in some regions require the installation of additional safety hardware. Other types of inverters available are DC-optimized inverters and micro-inverters.
In recent years the role of the PV inverter has expanded into smart energy management, including storage, grid interaction, home energy, EV charging, monitoring, safety, and more.
