Deye 18kW Single Phase Hybrid Inverter SUN-18K-SG01LP1-EU-AM3-P

The Deye 18kW Single Phase Hybrid Inverter (SUN-18K-SG01LP1-EU-AM3-P) is a powerful, intelligent energy storage inverter designed for large residential, commercial, agricultural, and backup power applications. Combining advanced solar power conversion, battery storage integration, and grid-interactive functionality, this inverter enables maximum energy independence, reduced electricity costs, and reliable power during grid outages. 

Engineered for high-performance solar systems, the Deye 18kW Hybrid Inverter supports up to 36,000W of PV input power, allowing oversized solar arrays to maximize energy production throughout the day. Featuring 3 independent MPPT trackers, it optimizes energy harvest from multiple roof orientations and varying sunlight conditions.

The inverter is compatible with both lithium-ion and lead-acid batteries and delivers an exceptional 350A maximum charge and discharge current, making it ideal for large-capacity energy storage systems. Intelligent battery management communicates directly with supported battery BMS systems for safe and efficient operation. 

Designed for ultimate flexibility, the Deye 18kW supports on-grid, off-grid, and hybrid operation, while allowing up to 16 units to operate in parallel for larger installations. It also supports AC coupling, enabling existing solar systems to be upgraded with battery storage without replacing current solar inverters. 

With a maximum efficiency of 97.6%, durable IP65 weatherproof protection, intelligent air cooling, and a responsive colour touchscreen LCD display, the inverter delivers reliable performance in demanding environments. Remote monitoring and system management are available through optional WiFi, Bluetooth, LAN, 4G, and GPRS communication modules.
