The 12kW Deye SUN-12K-SG04LP3-EU hybrid inverter is a three-phase, low-voltage (48V) hybrid inverter that enhances energy independence and optimizes the direction of energy flow and the sources or loads to which the energy is directed. With its compact design and high power density, this series supports a DC/AC ratio of 1.3, helping reduce investment in the device. It supports unbalanced three-phase output, expanding application scenarios. Equipped with CAN port (x2) for BMS and parallel use, x1 RS485 port for BMS, x1 RS232 port for remote control, and x1 DRM port, making the system smart and flexible. This series supports both single-phase and three-phase parallel applications, allowing up to 16 units to be connected. Thanks to the intelligent monitoring platform, Deye full series inverters support remote shutdown immediately upon failure detection.
