Deye 18kW Single-Phase Hybrid Inverter SUN-18K-SG01LP1-EU-AM3-P | 48V Low Voltage Solar Inverter
Product Description
The Deye 18kW Single-Phase Hybrid Inverter SUN-18K-SG01LP1-EU-AM3-P is a high-performance hybrid inverter designed for larger residential, commercial, and small industrial solar systems. With a powerful 18kW AC output, advanced hybrid energy management, strong battery charge/discharge capability, and flexible PV input design, this inverter is ideal for customers needing reliable solar, battery, grid, and generator integration.
This inverter combines solar PV generation, battery storage, grid supply, and backup power into one intelligent system. It helps improve solar self-consumption by prioritising solar energy first, battery storage second, and grid power when needed. With programmable battery charging and discharging time periods, users can also optimise energy usage around peak and off-peak electricity times.
The Deye 18kW single-phase inverter supports up to 16 units in parallel for on-grid and off-grid operation, making it a scalable option for larger installations or future expansion. It also supports energy storage from a diesel generator, making it practical for rural properties, farms, businesses, and sites with unreliable grid power.

Let customers speak for us
Still figuring out how the battery usage is managed, but as for the rest it operates seamless.
Got the app operational with a little help from my friend and gives useful information. Enjoying the Deye 12kW journey.
Still need to neaten-up the wiring though.
I thank you.
Overall, this inverter has exceeded my expectations. Highly recommended to anyone
