Efficient energy conversion for modern requirements

The Deye SUN-100K-G03 has been specifically developed to meet the high demands of modern, large-scale photovoltaic systems. With a three-phase output and a maximum efficiency of up to 98.7 %, the inverter ensures that the maximum proportion of the generated direct current is converted into grid-compliant alternating current, whilst minimising losses. By supporting a wide MPPT voltage range from 200 V to 850 V, the system remains efficient even under varying irradiation conditions.

Flexibility and scalability

Thanks to its up to 6 independent MPP trackers, the Deye SUN-100K-G03 allows for optimal adaptation to solar panel arrays with varying orientations or partial shading. This makes it perfectly suited to complex rooftop systems or ground-mounted installations with variable module layouts. Furthermore, its robust technical design allows for flexible system configuration to meet a wide range of project requirements.

Reliability and protection

With its IP65 protection rating, the inverter is optimally protected against dust and water. High-quality components, a wide operating temperature range from -25 °C to +60 °C (with derating above 45 °C) and an intelligent air-cooling system ensure long-lasting and stable operation, even under demanding conditions. Integrated protection mechanisms such as overvoltage and short-circuit protection, an anti-islanding function and residual current monitoring ensure maximum safety for both the system and the grid.

Who is the Deye SUN-100K-G03 suitable for?

This inverter is ideal for:

• Operators of large-scale solar installations who prioritise maximum energy yields and high cost-effectiveness
• Commercial enterprises and industries with high self-consumption or full feed-in to the grid
• Solar park operators who rely on reliable performance and comprehensive monitoring functions
• Agricultural businesses with high energy requirements and land suitable for PV installations

How many MPP trackers does the inverter have?

The Deye SUN-100K-G03 features up to 6 independent MPP trackers, ideal for complex system layouts.

What is the maximum efficiency of the appliance?

The inverter achieves an impressive maximum efficiency of up to 98.7 %.

What voltage range does the MPPT support?
