Description
Low-Frequency Solar Inverter-Charger (Parallel Version)
Core functions: Low-frequency toroidal transformer (anti-interference, low no-load loss), pure sine wave output, supports 9-unit parallel connection (total 90kW), drives inductive loads like drills/pumps.
Smart Battery: AI-optimized charging extends lithium battery life by 30%, with BMS communication, WiFi remote control, and generator auto-start dry contact.
High Compatibility: Dual MPPT solar input (max 100A charging), wide PV voltage range (60-245VDC), grid/off-grid auto-switching.
Rugged Design: 3:1 peak load capacity, multi-protection (overload/short-circuit/lightning/moisture), operates in -10°C~50°C harsh conditions.
Applications: Construction sites, farms, off-grid homes with high-power demands.
