The versatile low-voltage 3-phase hybrid inverter Deye SUN-12K-SG04LP3-EU with wall bracket combines a solar inverter and battery charger. It supports asymmetrical 3-phase output with a range of 0 to 5 kW on each phase, 100% overload capacity for 10 seconds, extending its usability to the absolute maximum. The converter is compatible with low-voltage 40V to 60V batteries. Communication with the BMS is via CAN or RS485 interface and is fully compatible with lead-acid and lithium batteries from many brands. The colour LCD display provides a user-friendly interface for system overview and configuration (battery management, AC/solar charging depending on different applications, etc.). The biggest advantage of this converter is the adjustable ‘smart load’ input/output, to which a generator, mains converter or heating element for water heating can be connected. The possibilities of this port allow you to use similar functions to a wattrouter.


This inverter has been successfully certified by the EG.D a.s. laboratory and can be permanently connected to the distribution network in the Czech Republic in accordance with the rules valid from 1 January 2025.
