Solar Solar Inverters

EHD8K

8kW | 310V

The EHD series split-phase high-voltage on-grid hybrid inverter supports flexible charging methods, including utility, generators, and solar energy. It also provides versatile power supply mode, such as grid bypass, off-grid operation, and on-grid feeding power.

The series features comprehensive and efficient energy management functions. It supplies power for daily use, stores excess power, and exports the remaining power to the grid. These benefits help to reduce electricity costs, decrease dependence on the grid, and improve power reliability.
