Deye 12kW LV Single Phase Hybrid Inverter

The Deye SUN-12K-SG02LP1-EU-AM3-P is a 12kW single-phase hybrid inverter for 48V low-voltage battery systems, built for large homes and light-commercial sites.

It takes up to 19.2kW of PV across three independent MPP trackers with two strings each, and charges and discharges a 48V battery bank at up to 250A. Grid, PV, battery and generator are all managed by the one unit, with six programmable time periods for charging and discharging so the system can follow a tariff or a load profile. It is rated IP65.

Why installers pick this unit

• Three MPP trackers, two strings each (2+2+2), with 32A per tracker on this -P version — room for modern high-current panels across several roof faces

• Parallels up to 16 units on- and off-grid, with multiple battery banks
• AC coupling to retrofit an existing grid-tied PV array, plus generator support
