The Deye SUN-8K-SG04LP3-EU 8kW hybrid inverter is a three-phase, low-voltage (48V) hybrid inverter designed to enhance energy independence and optimize the direction of energy flow as well as the sources or loads it is directed to. With its compact design and high power density, this series supports a DC/AC ratio of 1.3, reducing investment costs. It supports unbalanced three-phase output, expanding its application scenarios. Equipped with CAN ports (x2) for BMS and parallel connection, x1 RS485 port for BMS, x1 RS232 port for remote control, and x1 DRM port, making the system intelligent and flexible. This series supports single-phase and three-phase parallel applications, with the possibility to connect up to 16 units. With a smart monitoring platform, Deye full series inverters support remote shutdown immediately after a fault occurs.
