The Deye SUN-20K-SG05LP3-EU-SM2 is a powerful 20 kW three-phase low-voltage hybrid inverter with 350 A charge and discharge current – currently the strongest 48 V hybrid inverter on the market. Thanks to its transformer-isolated design and extremely high battery current, it is perfect for large residential systems and small commercial applications with high power requirements. 100 % unbalanced load (each phase up to 50 %), AC coupling for retrofitting, parallel operation of up to 10 units (on-grid & off-grid), diesel generator compatibility and six freely programmable time slots make this inverter the ultimate all-rounder. With a maximum PV input of 40 kW and 2 MPPTs (2+2 strings), it extracts every available watt.
