Solarmi Deye SUN-15K-SG05LP3-EU-SM2 Hybrid inverter with limiter, 15kW, 3-phase, 400V, Deye

Multifunctional 3-phase asymmetric (100%) hybrid inverter from manufacturer DEYE, which combines inverter functions, solar charger and battery charger. The biggest advantage of this inverter is the adjustable input/output „smart load“ where you can connect a generator, string inverter, or heating element for water heating. Comprehensive LCD display ensures user-configurable and easily accessible control (battery charging, AC/solar charging, allowable input voltage depending on different applications, etc.). It is equipped with RS-485/CAN port for communication and management. The inverter provides additional information, statistics, graphs + remote management option via supplied Wi-Fi dongle. The package includes probes for consumption measurement and datalogger (Wi-Fi). Electricity meter is not included.

These inverters are equipped with an excellent SmartLoad function, which allows connecting a 230V appliance only under certain conditions. To connect such an appliance, the GEN port is used, which can be changed in settings from a generator port to a smart-switched appliance port. So if, for example, the battery is charged to 90%, the inverter turns on the GEN port and connects, for example, a boiler. After the battery capacity drops to the set level, it disconnects the appliance on the GEN port again. This way, surpluses can be efficiently used for heating water in a boiler, pool, etc.

This inverter is approved for connection to the distribution system according to PPDS 2025. We will provide the RfG compliance verification report upon request.
