Victron Energy Bi Driectional Inverters
A bidirectional inverter, in a DC-distribution system, is a device that is used to regulate and monitor the flow of power between a DC bus and an AC grid and to restrict the voltage expanse at the former to only a certain permissible range of voltages. In other words, a bi-directional inverter is the one that not only performs the DC to AC conversion, but also performs the conversion of AC power to DC.
Fronius Grid Tie Inverters
A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, normally 230V RMS at 50 Hz.
