Product Overview
2.5 Micro Grid
Due to the islanding effect, on-grid inverters are unable to work off-grid. This feature
makes users lose the PV energy of on-grid inverters when off-grid. Micro-grid is a function
that makes hybrid inverters simulate the grid to activate an on-grid inverter during off-grid.
By connecting the on-grid inverter to the EPS port of the hybrid inverter, the hybrid inverter
is able to use PV or battery energy to activate the on-grid inverter when utility is lost.

* The hybrid inverter is unable to control an on-grid inverter, therefore a hybrid inverter
cannot achieve zero export to the grid when loads power + battery power < on-grid
inverter output power.
