This paper proposes an energy storage system with dual power inverters for microgrid islanding operation. A primary inverter charges or discharges power to manage the energy storage in normal state, and a secondary inverter provides voltage instead of the grid in island state that is invoked when the grid is unavailable.

For example, an average 5kW solar inverter costs around $1100, a 5kW hybrid inverter costs closer to $1500, and a standard 5kW off-grid inverter costs $2500. Additionally, for hybrid systems to provide backup power, most household switchboards need to be modified or upgraded, which adds to the total cost of installation.
