Chint CPS ECH3K-SML-EU Photovoltaic Hybrid Inverter: Complete Solution for Self-consumption and Backup

The Chint CPS ECH3K-SML-EU is a single-phase hybrid inverter of 3 kW that combines photovoltaic conversion with battery management to optimize energy self-consumption. Thanks to its 2 independent MPPTs, it can manage two strings of photovoltaic panels positioned on roofs with different orientations or in the presence of shading, significantly improving performance in all conditions.

In case of a blackout, the device is capable of powering priority loads, such as lights or a refrigerator, ensuring energy continuity and safety. This is particularly useful for homes or small installations that require a reliable energy source even when the electrical grid is unavailable.

Compatibility with Storage Systems and Intelligent Management

The inverter is compatible with lithium-ion or LiFePO batteries, technologies that offer high capacity and long life. The intelligent battery management system allows storing excess energy produced during the day, to then use it during peak consumption hours or in the evening, reducing bill costs and improving the overall efficiency of the system.

Intelligent monitoring via the dedicated app and Wi-Fi connection allows you to manage the system in real-time, viewing energy production, consumption, and battery status. Additionally, the RS485 and CAN connection offers advanced and versatile management for more complex installations.

Advanced Protections for Safety and Durability

The Chint CPS ECH3K-SML-EU is equipped with numerous protection systems, including:

  • DC Switch

  • Anti-islanding protection

  • AC overcurrent protection

  • AC overvoltage protection

  • String PV reverse polarity protection

  • Type II surge protection (DC and AC side)

  • Insulation detection

  • Leakage current protection

  • AFCI (Arc Fault Circuit Interruption)

These protections ensure that the system operates safely, preventing damage and increasing the device's lifespan.
