Deye SUN-20K-SG05LP3-EU-SM2 20kW Three-Phase Hybrid Inverter (48 V)

The SUN-20K-SG05LP3-EU-SM2 is a 20 kW three-phase hybrid inverter from Deye for large homes, hotels, schools, and commercial buildings, running on a 48 V low-voltage battery bank. Its 350 A charge and discharge current lets a large lithium bank supply the full load and recharge quickly from solar.

The output is fully unbalanced, with each phase able to deliver up to half the rated power, and the maximum apparent output is 22 kVA. Two MPPTs accept up to 800 V and track from 160 to 650 V.

It stores energy from a diesel generator, supports AC coupling with existing solar, schedules the battery over six time periods, and runs up to 10 units in parallel. RS485, RS232, and CAN ports connect batteries and monitoring, with Wi-Fi, GPRS, 4G, Bluetooth, or LAN modules available.

It is IP65-rated, operates from -40 to 60 °C, and peaks at 97.6% efficiency. We size the inverter, battery bank, and solar array to your actual loads and backup hours, and handle the installation, earthing, and surge protection.
