Deye SUN-10K-SG05LP3 – 10 kW three-phase low-voltage (48 V) hybrid inverter for residential and small commercial systems
The Deye SUN-10K-SG05LP3 (SUN-10K-SG05LP3-EU-SM2) is a 10 kW rated power, three-phase, low-voltage (48 V) hybrid inverter designed for residential and small commercial solar systems . The transformer-isolated design makes it compatible with the most common 48 V batteries (lithium-ion or lead-acid), while the 2 independent MPPTs optimize production even on roofs with different orientations and string configurations. It combines on-grid and off-grid operation in a single unit, providing a flexible solution for increasing self-consumption and backup power.
Why choose the Deye SUN-10K-SG05LP3 inverter?
The Deye SUN-10K-SG05LP3 inverter operates with up to 97.6% maximum and >99% MPPT efficiency, and uses intelligent algorithms to optimize energy use and storage. During the day, solar energy first powers the loads, with the surplus charging the battery or feeding the grid; in case of a power outage, the inverter automatically switches to battery mode, ensuring continuous supply. The 100% unbalanced output adapts to different loads per phase, and in off-grid mode the inverter can deliver twice the rated power for 10 seconds, enabling high inrush-current appliances (pumps, refrigerators, air conditioners) to start.

Applications
The Deye SUN-10K-SG05LP3 inverter is ideal for family homes, farms, and small businesses where three-phase, flexible, and reliable energy management is needed with 48 V battery storage. It helps maximize self-consumption, acts as a backup power source during outages, and with 6 programmable charge/discharge periods enables off-peak charging and peak-time discharge. AC-coupled expandability means existing solar systems can be retrofitted with storage.
