DEYE SUN-18K-SG01LP1-EU-AM3 – 18kW Single-Phase Low-Voltage Hybrid Solar Inverter

The DEYE SUN-18K-SG01LP1-EU-AM3 is a high-capacity 18kW single-phase hybrid solar inverter designed for demanding residential, commercial, and energy-storage applications. It combines solar PV generation, battery storage, grid power and generator support in one integrated energy-management solution. Deye’s published specifications identify the series as a 12–18kW single-phase, 3-MPPT, low-voltage-battery hybrid inverter.

The inverter supports 40–60V batteries, including lead-acid and lithium-ion batteries, with BMS self-adaptation for lithium batteries. The 18kW model supports up to 380A maximum battery charging and discharging current in the current manufacturer documentation.

For solar input, it supports up to 28.8kW rated PV input power and 36kW maximum PV access power, with a maximum PV voltage of 500V. Its 3 MPPT trackers with 6 PV strings provide greater flexibility when connecting multiple solar-panel arrays with different orientations or conditions.
