Hybrid Inverter DEYE SUN-12K-SG05LP3-EU-SM2, 12kW, 3-Phase, 5th Generation, LV

Product detailed description

The versatile low-voltage 3-phase hybrid inverter Deye SUN-12K, 5th generation, with wall mounting bracket 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, expanding application scenarios to the absolute maximum. The inverter is compatible with low-voltage 40 to 60V batteries. Communication with the BMS is via CAN or RS485 interface and it is fully compatible with the latest battery models from other brands. The color LCD display ensures a user-friendly interface for overview and system configuration (battery management, AC/solar charging depending on various applications, etc.). The biggest advantage of this inverter is the adjustable "smart load" input/output, to which a generator, string inverter, or heating element for water heating can be connected. This port's capabilities allow you to use functions similar to a wattrouter.
This inverter successfully passed PPDS certification in categories A1 and A2 on 24. 09. 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 territory of the Slovak Republic according to the rules valid from 1. 1. 2025.
