KY-EST SERIES

Hybrid Inverter/Three-phase 30KW ~ 60KW

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

KY-EST30KH/ KY-EST35KH/ KY-EST40KH/ KY-EST45KH/KY-EST50KH/ KY-EST55KH/ KYEST60KH/KY-EST65KH series inverters, also known as hybrid or bidirectional solar inverters, are suitable for photovoltaic , energy management of solar energy systems such as batteries, loads, and grids. The electricity generated by the photovoltaic panels is used for residential electricity, and the excess electricity can be stored in batteries. When the battery is fully charged, the user can send the 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 insufficient energy storage in the battery, the grid will supply power to the load through the system.The inverter has a transformerless topology and there is no isolation between DC input and AC output. Adaptive PV models must meet the IEC61730 class a standard. The energy management system is shown in Figure
