A solar inverter takes the DC electricity from the solar array and uses that to create AC electricity. Inverters are like the brains of the system. Along with inverting DC to AC power, they also provide ground fault protection and system stats, including voltage and current on AC and DC circuits, energy production and maximum power point tracking.Micro-inverters optimize for each individual solar panel, not for an entire system, as central inverters do. This enables every solar panel to perform at maximum potential.
