Advantages
1.Seamless Integration with Low Voltage Systems
The inverter is designed to work seamlessly with 48V lithium-ion and lead-acid batteries to optimize reduced capital costs by prioritizing inexpensive energy storage. The adaptive battery management system ensures that batteries undergo their necessary charging and discharging cycles to protect their operating lifecycle while maximizing usage. The inverter works with a number of battery brands, enhancing system design flexibility without compromising integrity.
2. Intelligent Energy Management
With dynamic tariff mode support, the Solis 8-18k hybrid three-phase low-voltage inverter can intelligently adjust the price fluctuations of hybrid three-phase low voltage, thereby achieving maximum energy savings during off-peak hours. Dual backup ports can be set up to prioritize circuit loads during power outages while temporarily dropping non-essential loads. The result is the capability for the inverter to act like an intelligent energy manager that is customizable for various operational needs.
3. Exceptional Longevity in Severe Environments
Engineered to operate reliably in extreme conditions, the Solis inverter delivers reliable performance over a temperature range of -40°C to 60°C while operating at elevations up to 4,000 meters. Its enclosure has an IP66 rating that makes it completely dustproof and waterproof, making it suitable for outdoor installs whether they are on a tropical, dry, or coastal installation. With advanced thermal management and robust cooling systems, the inverter can deliver steady performance in high load applications.
4. Modular Construction for Changing Energy Requirements
The Solis 8-18K Hybrid Inverter was designed to be configured in parallel by interconnecting up to six inverters, enabling scalable power output to meet future energy demands. Our modular design simplifies an expansion to existing systems without requiring a large investment in a new design, whether extending from a residential system or deploying a commercial microgrid.
