features
Key Features
Battery-Ready Hybrid Architecture
Future-proof your installation with a reserved battery port ready for seamless integration with the modular SigenStack BESS, no additional power conversion system (PCS) needed.
Smallest & Lightest in Class
Save on transport and installation with an industry-first compact footprint. Up to 19% lighter and 36% smaller than traditional C&I inverters.
Integrated EMS
Eliminate the need for external data loggers or controllers. The built-in Energy Management System allows multiple inverters to operate in parallel while enabling one unit to function as a central management host.
Next-Level Safety with Extended AFCI
Industry-leading 500m arc fault detection range with advanced signal fusion algorithms ensures maximum safety in large-scale rooftop deployments.
Self-Adaptive Phase Sequencing
Thanks to AI-driven algorithms, the inverter automatically adjusts for phase sequence errors and CT polarity issues during installation, drastically reducing commissioning time and complexity.
