Sungrow SG4.0RS Single-Phase Grid-Tied Inverter – The smart choice for maximum solar energy yield
Smart investment in solar energy means choosing an inverter that is not only powerful and efficient but also intelligent and reliable. The Sungrow SG4.0RS is a single-phase grid-tied inverter with a nominal AC power of 4000W, and it's no surprise that this model is increasingly preferred by professionals and DIY enthusiasts. With its European efficiency of 97.5% and dual MPPT technology, you can extract the maximum energy from your solar panels.
Why choose the Sungrow SG4.0RS?
A major advantage of this inverter is that you can install more solar panels than the 4000W nominal AC output. This means you can increase the total DC input power up to 6000W without any issues. This allows you to maximize your panels' energy production, even on cloudy days, without energy loss.
What makes this inverter unique?
- Overdimensioning up to 6000W DC – More panels mean increased yield.
- High efficiency (97.5%) – Lower energy losses result in optimal production.
- Dual MPPT – Maximizes power output from different panels, even in partial shading.
- IP65 protection rating – Suitable for indoor and outdoor installations, weather-resistant and durable.
- Wide MPPT voltage range – Flexible panel configuration, ideal for small and large systems.
- Smart monitoring – Real-time data and updates via iSolarCloud, accessible via smartphone and PC.
- Lightweight (10 kg) – Easier to install than many competitors.
- Built-in PID Zero technology – Prevents panel degradation and extends lifespan.
Comparison with other models
- Fronius Primo 4.0-1: Lower maximum DC power, does not support PID Zero technology, leading to faster panel degradation.
- SMA Sunny Boy 4.0: Limited MPPT voltage range, reducing energy yield under variable conditions.
- Huawei SUN2000-4KTL: Advanced model but less compatible with existing PV systems and less user-friendly for monitoring.
- Sungrow SG4.0RS: Supports more panels, offers a wider MPPT voltage range, and includes smart protection technologies.
Installation & Usage
This inverter is designed for easy installation in garages, technical rooms, or outdoor locations. Thanks to its IP65 protection rating, it is resistant to moisture and dust. Real-time monitoring via iSolarCloud ensures full control over your solar energy yield, wherever you are.
