The Deye SUN-20K-SG05LP3-EU-SM2 is a three-phase hybrid inverter rated at 20 kW for 48 V low-voltage batteries. It belongs to the SM2 series (14–20 kW) and is intended for larger family homes, farms and smaller businesses that need more power but want to stay with safe 48 V batteries.

The inverter has two MPPT trackers with a range of 160–650 V (maximum input voltage 800 V). The first tracker accepts two strings with a current of up to 36 A, the second one string with a current of 20 A. The maximum PV power is 30,000 W. When loads start up, it briefly delivers twice its rated power for 10 seconds.

The battery is connected in the 40–60 V range with a charge and discharge current of up to 350 A — enough to charge even a large battery built from Deye SE-F16-C modules quickly. We offer ready-made SUN-20K sets with one to three SE-F16-C batteries (16–48 kWh). Up to 10 inverters can be connected in parallel. The output supports fully unbalanced loads — each phase can deliver up to 50% of the rated power.

IP65 protection and operation from -40 to +60 °C also allow outdoor installation. Dimensions 456 × 750 × 268.5 mm, weight 50.6 kg, noise level below 60 dB, rated AC current 30.4/29 A. Communication via RS485, RS232, CAN, WiFi and Bluetooth, efficiency 97.6% (European 97.0%). The inverter supports 6 time slots for charging and discharging and the connection of a diesel generator.

The inverter carries a 10-year warranty. The datasheet is available in the Documents tab.
