DEYE hybrid inverter 12 kW, 3 phase, LV, 5th generation

The versatile low-voltage 3-phase hybrid inverter Deye SUN-12K 5th generation with wall mount combines a solar inverter and battery charger. It supports asymmetric 3-phase output ranging from 0 to 6 kW per phase, with a 100% overload capability for 10 seconds, thus expanding application scenarios to the absolute maximum. The inverter is compatible with low-voltage 40 to 60V batteries. Communication with BMS is via CAN or RS485 interface and is fully compatible with the latest models of batteries from other brands. The color LCD display provides a user-friendly interface for overview and configuration of the system (battery management, AC/solar charging depending on various applications, etc.). The greatest advantage of this inverter is the adjustable input/output “smart load” where a generator, string inverter, or heating element for water heating can be connected. The options of this port allow you to utilize similar functions as a wattrouter.

This inverter has successfully passed PPDS certification in categories A1 and A2 on September 24, 2025, at the clean energy laboratory, EG.D in České Budějovice. Based on these certificates, it can be permanently connected to the distribution grid in the Czech Republic according to the rules effective from January 1, 2025.
