Residential Energy Storage Systems
Our single phase hybrid inverter is designed for modern residential and small commercial energy storage applications, combining grid-connected operation, off-grid capability, and reliable backup power in one compact solution.
With support for 48V battery systems, high MPPT efficiency, and full EU grid compliance, it provides installers and system integrators with a stable, flexible, and future-proof hybrid inverter solution.
Available in 3.6kW, 5kW, and 6kW, this inverter is optimized for European single-phase power networks and widely used in home solar energy storage systems, villas, and small commercial projects.
for On-Grid, Off-Grid, and Backup Applications
This single phase hybrid inverter supports multiple operating modes, allowing the system to adapt to different grid conditions and user requirements:
- Grid-connected operation for maximum self-consumption
- Off-grid operation when utility power is unavailable
- Backup power supply with fast switching time under grid failure
With a switching time of less than 10ms, critical household loads can continue operating seamlessly during power outages, ensuring energy security for residential users.
System Stability & Risk Control
Long-term system stability is critical for residential energy storage installations, where unplanned downtime directly affects end users and service costs. This inverter integrates a comprehensive protection architecture, including DC isolation, PV and battery reverse connection protection, output short-circuit and over-voltage protection, as well as insulation impedance monitoring. The fanless natural cooling design and IP65 enclosure further enhance reliability by minimizing mechanical wear and allowing stable operation in outdoor environments. Together, these features form a robust risk-control foundation, helping system integrators deliver reliable hybrid energy systems with lower maintenance requirements and predictable long-term performance.
