Deye SUN-20K-SG05LP3-EU-SM2 Hybrid Inverter 20kW Three-Phase
The Deye SUN-20K-SG05LP3-EU-SM2 is a three-phase 20kW hybrid inverter from the top end of the low-voltage range: the usual pick for large houses, farms and small workshops that want to store energy in 48V LiFePO4 batteries without moving to high voltage. Two MPP trackers rated 36A each accept very large PV arrays, and the backup output keeps essential loads running through a blackout.
It offers two battery inputs and a very high charge and discharge current, so it makes full use of the high-capacity rack banks in the Litio Store catalogue with a CAN-communicating BMS. It supports up to 10 units in parallel on-grid and off-grid, AC coupling to retrofit an existing PV system, and charging from a diesel generator.
Key features
Two 36A MPPTsEach tracker takes up to 36A and two strings, with 54A permissible short-circuit current: room for very large PV arrays.
Two battery inputs, 350ACharge and discharge current reaches 350A across two independent inputs, ideal for high-capacity 48V LiFePO4 rack banks.
AC passthrough up to 70AThe grid-to-load bypass carries 70A continuously, so essential loads stay supplied even beyond the inverter's rated power.
Unbalanced output and parallelingThe three-phase output can be 100% unbalanced and up to 10 units can be paralleled, on-grid and off-grid.
