The Deye SUN-6K-G — is a modern, next-generation single-phase grid-tied inverter designed for the efficient operation of small solar power plants (SPPs) with a capacity of up to 6 kW. The device combines advanced power conversion technologies, intelligent monitoring, and a wide range of safety features. Its maximum efficiency is 97.5%, and its maximum power point tracking (MPPT) efficiency exceeds 99%. This allows for maximum energy output even when light conditions change or modules are partially shaded.
The inverter is equipped with two independent MPPT trackers, allowing two groups of solar panels with different parameters or orientations to be connected to it. The model features a low starting voltage—from 80 V—and a wide MPPT operating range (70–500 V), ensuring the system starts operating early in the morning and maintains stable energy generation even in cloudy weather. The built-in Zero Export and VSG (Virtual Generator) functions allow for effective management of energy flows and prevent unwanted export to the grid, which is particularly relevant for residential and commercial systems with self-consumption.
Key Benefits
- 2 MPPT trackers — high flexibility during system design, optimization of panels with different orientations.
- Maximum efficiency — 97.5%, European standard — 97%, MPPT efficiency > 99%.
- Zero Export and VSG — full support for limiting energy export to the grid and operation in virtual generator mode.
- Anti-PID function (optional) — prevents degradation of solar cells due to potential-induced effects.
- Wide MPPT range of 70–500 V and low start-up voltage of 80 V — early start-up and stable generation.
- Intelligent network monitoring (optional) — remote control via Wi-Fi, 4G, Bluetooth, or LAN.
- Full set of protections: short circuit, overvoltage, overheating, ground fault, anti-islanding, DC reverse polarity.
- Type II SPDs for DC and AC — reliable protection against surge voltages and lightning strikes.
- IP65 protection rating — suitable for outdoor installation, dust- and moisture-proof enclosure.
- Natural cooling without fans — completely silent operation, no dust wear.

Design features
The Deye SUN-6K-G05 features a compact housing that combines elegant design with high functionality. Thanks to its IP65 rating, the inverter is ideal for outdoor installation—on the walls of private homes, utility buildings, or technical rooms. Its natural cooling ensures complete silence, and the absence of fans reduces the need for maintenance. High-quality electronic components ensure stable operation even at high temperatures and during voltage fluctuations.
Intelligent features such as Zero Export and VSG make the inverter flexible in energy management. This allows users to maximize the use of their own generation, increasing the share of self-consumption. The inverter can also be connected to the Deye Cloud system—an online monitoring platform that displays operating parameters, generation and consumption graphs, and performance statistics.
Applications
- Residential rooftop solar power plants (private homes, cottages, villas).
- Small business facilities (cafes, offices, warehouses, hotels).
- Microgrids with energy export limitation (Zero Export) or VSG mode.
- Off-grid power systems with generators or batteries (as part of Deye hybrid solutions).
