Product Features
- Ultra-Low 80V Startup & Wide MPPT Voltage: Starts generating clean power earlier in the morning and continues later in the evening (70V–500V MPPT range), maximizing daily solar energy yield even in low-light or cloudy conditions.
- Maximum 97.5% Efficiency: Single high-precision MPP tracker delivering up to 97.5% peak conversion efficiency (99% MPPT efficiency) for optimal rooftop ROI.
- High-Current PV Module Ready: Supports up to 20A max operating input current and 30A short-circuit current, perfectly compatible with modern high-power 182mm/210mm solar panels.
- Smart Zero-Export & VSG Support: Built-in zero export capability prevents feeding surplus power into the grid when restricted; VSG application enhances grid stability and voltage support.
- Compact, Quiet & Weatherproof (IP65): Natural heat dissipation (fanless design) ensures zero noise for living areas. Durable IP65 enclosure withstands harsh outdoor weather environments.
- Comprehensive Electrical Protection: Integrated DC reverse-polarity protection, AC overvoltage/overcurrent, short-circuit, ground-fault, thermal, and optional Anti-PID function.
- Intelligent Monitoring & Flexible Connectivity: Supports multiple communication options (Wi-Fi / 4G / LAN / Bluetooth / RS485 / GPRS) for real-time remote diagnostics and smart cloud management.

FAQ Section
Q1: What is the power range of the Deye SUN-(1-4)K-G04P1-EU-AM1 series?
A: The series covers 10 single-phase on-grid models ranging from 1kW to 4kW rated power output (1kW, 1.5kW, 2kW, 2.2kW, 2.5kW, 2.7kW, 3kW, 3.3kW, 3.6kW, and 4kW), designed for residential rooftop solar applications.
Q2: Can this Deye string inverter support high-power 500W+ solar panels?
A: Yes. The inverter supports up to 20A maximum operating DC input current and 30A short-circuit current, making it fully compatible with modern high-power 182mm and 210mm monocrystalline PV modules.
Q3: How does the 80V low start-up voltage benefit my solar system?
A: The ultra-low 80V startup voltage allows the inverter to wake up earlier at dawn and shut down later at dusk compared to standard inverters requiring 100V–120V+. This broadens daily generation hours and captures more solar yield in low-irradiance conditions.
Q4: Does the SUN-1-4K-G04P1 support Zero Export functionality?
A: Yes. When paired with an optional smart energy meter or CT, the inverter supports zero-export and self-consumption management, preventing unwanted surplus energy from being exported to the local electricity grid.
Q5: Is the inverter suitable for outdoor residential installation?
A: Absolutely. It features an IP65 weatherproof rating and fanless natural cooling design. It operates silently (<25dB) and can be mounted on exterior walls or shaded outdoor locations with an operating temperature range of -25°C to +60°C.
Q6: What certifications does the Deye SUN-1-4K-G04P1 comply with?
A: It complies with major international and European grid standards including VDE-AR-N 4105, EN 50549, CEI 0-21, UK G98/G99, RD 140, as well as safety and EMC standards IEC/EN 62109-1/2 and IEC/EN 61000-6.
