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

The versatile low-voltage 3-phase hybrid inverter Deye SUN-5K 5th generation with a wall mount combines a solar inverter and a battery charger. It supports asymmetric 3-phase output with a range of 0 to 2.5 kW per phase, with a 100% overload possibility for 10 seconds, thereby 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 is fully compatible with the latest models of batteries from other brands. A 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 capabilities of this port allow you to utilize similar functions as a watt router.

This inverter successfully passed certification PPDS 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 network in the Czech Republic under the rules effective from 1. 1. 2025.
