2.1 System Diagram

RX-5000AC is an AC-coupled inverter. AC-coupled inverter provides advanced storage and
upgrading solutions to the PV grid-connected inverters(any brand or model), enabling the existing
system to benefit from energy storage capability and emergency power supply. The AC-coupled
inverter will detect the energy generated by the grid-connected inverter, which will be used by the
local load first, and the rest will be stored in the battery through the AC-coupled inverter, and the
surplus energy will be fed back to the grid.
Anti-Islanding Protection
The Islanding effect is a special phenomenon when a grid-connected PV system supplies power to
the grid, when the grid has suffered a power loss. Feeding power into a grid during a power loss is
dangerous for maintenance personnel and the public. The RX-5000AC inverter provides Anti-
Islanding Protection to prevent the islanding effect.
