Key Features1. High Charging/Discharging Current: The SUN-(3.6-6)K-SG03LP1 series supports a maximum charging and discharging current of 135A, facilitating rapid and efficient battery cycling. This means your energy storage system can quickly adapt to fluctuations in energy demand and supply.2. Diesel Generator Compatibility: This series is designed to store energy from diesel generators, making it particularly valuable in off-grid setups where reliable energy sources might be varied. This compatibility enhances the inverter’s versatility in hybrid energy systems.3. Parallel Operation: Up to 16 units of these inverters can be connected in parallel, enabling both on-grid and off-grid operations. This feature offers scalability and flexibility, catering to larger installations and future expansions without significant reconfiguration.4. Multiple Battery Compatibility: The inverters support parallel connection of multiple batteries, catering to increased energy storage needs. This is particularly useful in scenarios where energy storage capacity needs to be scaled up over time.5. AC Coupling: AC coupling allows for easy retrofitting of existing solar systems, making upgrades both seamless and cost-effective. This ensures that older systems can benefit from the latest technologies without the need for complete overhauls.6. Advanced Charging Management: The inverter supports up to 6 time periods for battery charging and discharging. This allows users to optimize energy usage based on time-of-use tariffs, thereby reducing energy costs.7. User-Friendly Interface: Equipped with a colorful touch LCD screen, the inverter allows for intuitive interaction and monitoring. Additionally, its IP65 protection rating ensures durability in various environments, adding to its reliability.Technical Specifications
