Residential solar + storage systems (villas, apartments, multi-family houses)
Small commercial energy storage systems (shops, offices, workshops)
Backup power systems for critical loads
Hybrid PV + battery systems for peak shaving and tariff optimization
Off-grid and weak-grid energy applications
Grid & System Control Capability
The system supports automatic synchronization with the utility grid and maintains stable operation under voltage and frequency fluctuations.
It is designed to comply with international grid connection requirements including IEC and EN standards.
Factory Quality Control
<0.1% DOA Rate: Every hybrid inverter undergoes a mandatory 4-hour automated simulation test under 100% full thermal and load conditions before final packing.
BMS Interoperability Lab: Production lines utilize automated battery simulation rigs to guarantee firmware communication compatibility before shipping.
