Product Description


Higher yields / Safe & Reliable / Smart / User-friendly:
The SUN 3/6K-SG04 hybrid inverter is an ideal solution for residential and light commercial applications. It not only optimizes solar energy self-consumption but also enhances energy independence, ensuring a steady supply of power throughout the day. During daylight hours, the PV system generates electricity primarily for loads, while excess energy charges the battery via the SUN 3/6K-SG04. This ensures that any extra power is not wasted, and can be utilized when required. Moreover, stored energy can be released when required by loads, providing uninterrupted power. The battery can also be charged by a diesel generator, ensuring continuous power during grid outages. Additionally, the hybrid inverter features RS485/CAN ports for battery communication, enabling seamless integration with 24V batteries and significantly improving system safety. With the SUN 3/6K-SG04 hybrid inverter, you can enjoy peace of mind and energy independence.
