Description

The Deye SUN-12K-SG05LP3-EU-SM2 is a powerful three-phase hybrid inverter with a nominal power of 12 kW, integrating photovoltaics, battery storage, and the power grid into one system. As a low-voltage device for 48V batteries, it is ideal for homes and businesses looking to store their solar power and significantly increase their energy independence.

Main Advantages for Your System

Full Phase Flexibility: 100% asymmetric output – each phase delivers up to 50% of the nominal power, reliably supplying unevenly distributed loads.
High Storage Performance: Up to 240 A charging and discharging current for your 48V low-voltage battery storage.
Flexibly Expandable: Up to 10 devices in parallel in grid and off-grid operation, including AC coupling for retrofitting existing PV systems.
Generator Support: Integration of a diesel generator and 6 freely adjustable charging and discharging periods for maximum self-consumption.

Maximize Your Solar Power Usage

With two independent MPP trackers and a maximum PV connection power of 24 kW, the SUN-12K extracts the maximum even from complex or shaded roof areas. The MPPT voltage range of 200 to 650 V allows for flexible module wiring, while the maximum efficiency of 97.6% keeps conversion losses low. With six adjustable charging and discharging periods, you can strategically use favorable grid tariffs and store excess solar power for evening and nighttime hours.

The inverter operates in parallel with the grid and can be supplemented with a diesel generator if needed, ensuring a reliable supply even in locations without a stable grid. Thanks to IP65 protection and an operating temperature range of -40 to +60 °C, the device is designed for demanding outdoor use. With integrated interfaces for WiFi, RS485, and CAN, you can conveniently monitor generation, consumption, and battery status at any time.
