Deye SUN-14K-SG05LP3-EU-SM2 hybrid inverter

Deye SUN-14K-SG05LP3-EU-SM2 is an advanced three-phase hybrid inverter that forms the heart of a modern photovoltaic system, combining efficient solar energy production with reliable storage. Designed for maximum performance and safety, this model is an ideal solution for homes and businesses seeking complete energy independence and optimal energy usage.

The Deye SUN-14K-SG05LP3-EU-SM2 inverter stands out for its ability to operate both on-grid and off-grid. Its architecture allows for the connection of low-voltage 48 V batteries, both lead-acid and lithium-ion, with transformer isolation for increased safety. The self-adaptation function to the Battery Management System (BMS) ensures optimal cooperation and long battery life. The SUN-14K-SG05LP3-EU-SM2 model supports a maximum charging and discharging current of 260 A and offers six programmable battery charging and discharging periods, allowing precise energy management. Additionally, it supports energy storage from a diesel generator, providing comprehensive power management.

In terms of performance and scalability, this Deye hybrid inverter allows parallel operation of up to ten units, both on-grid and off-grid, and also supports connecting multiple batteries in parallel to increase system capacity. It provides 100% unbalanced power on each phase, with a maximum output power of up to 50% of the rated power, and its off-grid peak power can reach twice the rated power for 10 seconds. The PV inputs feature a wide MPPT voltage range from 160 to 650 V and a high starting voltage of 160 V, with a maximum PV input voltage of 800 V. The inverter has two MPPT ports with two or four strings (2/2+2), which maximizes solar energy harvesting. Its impressive efficiency of 97.6% maximum efficiency, 97.0% European efficiency, and over 99% MPPT efficiency demonstrates the exceptional performance of the device.

User safety of the Deye SUN-14K-SG05LP3-EU-SM2 is a priority, confirmed by an integrated set of advanced protections, including DC reverse polarity protection, AC overcurrent output, AC overvoltage, AC short circuit, thermal protection, insulation impedance detection, DC component monitoring, arc fault circuit interrupter (AFCI) and DC switch, as well as anti-islanding protection and residual current detection. The transformerless design combined with intelligent air cooling and low noise level below 55 dB(A) ensures quiet and reliable operation. Its environmental resistance is confirmed by an IP65 protection rating, allowing safe outdoor installation in a wide temperature range from -40°C to +60°C (with power derating above 45°C).

System monitoring and management are intuitive thanks to the LCD display and various communication interfaces such as WIFI, RS485, and CAN. Deye also provides warranty support. Deye SUN-14K-SG05LP3-EU-SM2 is a comprehensive, high-performance solution that ensures reliable and intelligent energy management for your photovoltaic installation.
