A solar inverter is used to convert the Direct Current (DC) electricity generated by solar panels into a usable form of Alternating Current (AC) that can be utilized to integrate with the grid or run AC home appliances. Solar panels are wired together in series (a string of panels) which increases the voltage and keeps the current low so that wiring is simpler and wire size can be smaller. String inverters are designed to be wired to a single series string of 8-15 solar modules and are currently the most widely used inverter type. String inverters are typically warranted for 10 years but this period can be extended to 20 years.
