Deye SUN-15K-SG05LP3-EU-SM2 Hybrid Inverter 15 kW Three-Phase

The Deye SUN-15K-SG05LP3-EU-SM2 is a three-phase 15 kW 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 48 V LiFePO4 batteries without moving to high voltage. Two MPP trackers rated 36 A 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 36 A MPPTsEach tracker takes up to 36 A and two strings, with 54 A permissible short-circuit current: room for very large PV arrays.
Two battery inputs, 280 ACharge and discharge current reaches 280 A across two independent inputs, ideal for high-capacity 48 V LiFePO4 rack banks.
AC passthrough up to 70 AThe grid-to-load bypass carries 70 A 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.
