Description
Low-Frequency Energy Storage Inverter (Grid/Parallel Version)
Key Features: Low-frequency toroidal transformer (low no-load loss, high anti-interference), pure sine wave output, supports 9-unit parallel connection (total 90kW), powers heavy loads like AC units/pumps.
Smart Energy Control: AI-optimized charging, BMS communication (20+ lithium battery protocols), WiFi/GPRS remote monitoring, generator auto-start dry contact.
High Efficiency: Dual MPPT solar input (max 120A charging), wide PV voltage range (60-200VDC customizable), grid/off-grid auto-switching, 98% conversion efficiency.
Rugged Protection: 3:1 peak load capacity, multi-protection (overload/lightning/moisture), operates in -10°C~40°C harsh conditions.
Applications: Home energy storage, off-grid power stations, emergency backup for high-demand scenarios.
