PV Inverter Test – A PV inverter is a device that changes DC power to AC power and is also a key component in PV systems. There are two main types of PV systems, Grid Connected and Off Grid. Grid connected systems are usually installed on a building and provide electricity directly to the mains supply. Off grid systems are usually used where power is required but access to a mains supply is unavailable.

Ainuo Systems Solutions provides PV inverter test solutions based on thirty years of experience in power electronics testing. These solutions include:

Solar Array Simulator: DC Power Supply with SAS used to simulate the output characteristics of a solar array. This function is needed for MPPT performance evaluation of PV inverter devices.

Digital Power Meter: Used to measure PV inverter output parameters, such as V, I, P, PF, current harmonics & THD.

AC Power Source: Used to simulate mains power for various scenarios.

AC Load: Used to sink current directly for testing off grid type PV inverters. Ainuo’s AC Source provides a voltage level as the reference for the PV inverter output, but the AC source can not sink current (energy); therefore, an external resistor is necessary for load simulation.
