DEYE hybrid inverter 15 kW, 3 phase, LV, 5th generation

The versatile low-voltage 3-phase hybrid inverter Deye SUN-15K 5th generation with a wall mount combines a solar inverter and battery charger. It supports an asymmetric 3-phase output with a range of 0 to 7,5 kW per phase, 100% overload capacity for 10 seconds, maximizing its application scenarios. 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 battery models from other brands. A color LCD display provides a user-friendly interface for system monitoring and configuration (battery management, AC/solar charging based on various applications, etc.). Its greatest advantage is the adjustable input/output "smart load," which can connect a generator, string inverter, or heating element for water heating. This port offers functionality similar to a watt router.

This inverter successfully passed certification on August 19, 2025, at the Engineering Test Institute, and can be permanently connected to the distribution network within the territory of the Czech Republic in accordance with the regulations effective from January 1, 2025.
