Hybrid Inverter/Three-phase 10KW ~ 20KW

FFD POWER KY-EST Series Hybrid Inverter/Three-phase

KY-EST12KH/ KY-EST15KH/ KY-EST17KH/ KY-EST20KH series inverters, also known as hybrid or bidirectional solar inverters, are suitable for energy management of solar energy systems .such as photovoltaics, cells, loads, and power grids. The electricity generated by photovoltaic panels is used for residential electricity, and excess electrical energy can be stored in batteries. When the battery is fully charged, the user can send excess power to the grid.

When the photovoltaic power is not enough to meet the user’s load demand, the battery will discharge to the load. If there is not enough energy storage in the battery, the grid will supply power to the load through the system.

The inverter has a transformerless topology and is not isolated between the DC input and AC

output. Adaptive PV models must meet IEC61730 Class A standards.The energy management system is shown in Figure
