3-6kw single phase residential hybrid inverter
Overview:
The ELS series 3-6kw single-phase residential hybrid inverter supports flexible charging options,
including utility, generators, and solar energy. It also provides versatile power supply mode, such
as grid bypass, off-grid power supply, 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.
