Dayliff Ultraverter Grid-Tie Inverters are advanced transformerless inverters engineered for efficient management of hybrid solar PV and AC mains power systems. These inverters convert DC power generated by photovoltaic (PV) modules into AC power—either single-phase or three-phase, depending on the model—prioritizing PV generation and supplementing grid power when solar output is insufficient. Each inverter is equipped with Maximum Power Point Tracking (MPPT) technology to maximize energy harvest and ensure optimal performance under varying solar conditions. To comply with grid regulations, all models require connection to an external power export limiting meter, which actively monitors and restricts any excess power from being fed back into the grid.
Ultraverter inverters are designed for scalable installations, allowing multiple units to operate in parallel, each powered by independent solar arrays to support systems of virtually unlimited capacity. Remote monitoring and control are facilitated enabling real-time performance tracking and diagnostics.Particular features include:-
- LCD screen and LED status indicators; includes multifunction navigation buttons for simplified operation and maintenance
- Multiple communication interfaces: RS485, Wi-Fi and GPRS for flexible remote monitoring
- Comprehensive built-in protections: DC reverse polarity, short circuit, output overcurrent, overvoltage, insulation resistance monitoring, residual current detection, surge protection, anti-islanding, and over-temperature protection
- Fanless design for silent operation
- IP66-rated enclosure for superior water and dust ingress protection
- Lightweight and compact
Dayliff Ultraverter Inverters offer high overload tolerance, excellent thermal management, superior PV utilization efficiency, and minimal maintenance requirements and are an ideal solution to the application of PV power generation for hybrid PV/mains supply power .
