SUN-70/75/80/90/100/110K-G03

Key Features and Benefits

1. Exceptional Efficiency: The SUN-G03 inverters boast a maximum efficiency of up to 98.8%, with a European efficiency rating of up to 98.2%. This high efficiency translates to more energy being converted from the solar panels into usable electricity, minimizing losses and maximizing the return on investment for solar installations.
2. Multiple MPPT Channels: With up to 6 Maximum Power Point Tracking (MPPT) channels, these inverters can optimize the power output from multiple strings of solar panels. This feature is particularly beneficial for installations with varied orientations and shading conditions, as it allows the inverters to precisely track the optimal power point of each string.
3. Wide MPPT Voltage Range: The inverters operate over a broad MPPT voltage range of 200-850V, providing greater flexibility in system design and allowing them to accommodate a variety of solar panel configurations.
4. Advanced Safety and Protection Features: The SUN-G03 series includes a comprehensive suite of protection mechanisms, such as DC polarity reverse connection protection, AC output overcurrent and overvoltage protection, AC output short circuit protection, thermal protection, and ground fault current monitoring. These features enhance the safety and reliability of the solar power system, protecting both the equipment and the grid connection.
5. PID Mitigation and Zero Export Functionality: The optional Anti-PID (Potential-Induced Degradation) function helps to maintain the performance of the solar panels over time. Additionally, the zero export capability ensures compliance with grid export limits, making these inverters suitable for regions with strict grid regulations.
6. Robust Design: Encased in an IP65-rated enclosure, the SUN-G03 inverters are designed to withstand harsh environmental conditions. Their intelligent air cooling system ensures efficient thermal management, allowing them to operate within a wide temperature range of -25°C to +60°C, with derating above 45°C.
7. Comprehensive Grid Compliance: These inverters meet multiple international grid regulations and safety standards, including IEC 61727, IEC 62116, EN 50549, and VDE-AR-N 4105. This compliance ensures their compatibility and safe operation across various regions and grid conditions.
8. Versatile Communication and Monitoring Options: The SUN-G03 series supports various communication interfaces such as GPRS, Wi-Fi, Bluetooth, 4G, LAN, RS485, and RS232. This range of options facilitates flexible monitoring and control, enabling users to effectively manage and optimize their solar power systems.
9. Lightweight and Compact: Despite their high power capacity, the inverters are designed to be compact and relatively lightweight (approximately 81 kg), with dimensions of 824×516×312.7 mm. This design simplifies the installation process and integration into existing systems.
10. Grid Support and Power Quality: The Virtual Synchronous Generator (VSG) functionality and excellent total harmonic distortion (THD) rate of less than 3% support grid stability and power quality, making these inverters an excellent choice for modern grid-connected solar systems.
