Product Description
High-Efficiency Solar Inverter with LiFePO4 Communication
Advanced solar inverter featuring PF1.0 performance, dual charging capability, and RS485 communication for LiFePO4 battery systems.
Product Highlights
- Lithium Battery Activation via PV or Utility - Wakes up deeply discharged Li-ion batteries, preventing premature disposal
- Battery-Free Operation - Works grid-connected or directly from PV, lowering initial costs for budget-conscious off-grid installations
- Pure Sine Wave Output - Clean power for all loads including air conditioners, refrigerators, and motors
- Power Factor 1.0 - Delivers full rated power without derating, maximizing real load capacity
- Wide PV Input Range - 60Vdc to 500Vdc MPPT voltage, compatible with various solar panel configurations
- High-Current Built-in MPPT - Solar charge current up to 60A-120A with PV-to-inverter efficiency up to 96%
- Multiple Output Priority Modes - UTL, SOL, SBU, SUB for flexible energy management
- Battery Equalization (EQ) - Optimizes battery bank performance and extends cycle life
- Detachable Dust Cover - Easy cleaning, ideal for harsh/dusty environments
- Optional WiFi Remote Monitoring - Real-time system status via smartphone or PC
Key Technical Features
- LiFePO₄ Communication via RS485 - Intelligent BMS interaction for safe and efficient charging/discharging
- Dual-Source Charging - PV + AC grid can deliver total charge current up to 60A-120A (model dependent)
- Wide AC Input Range - 90-280Vac with selectable modes for personal computers (170-280V) or home appliances (90-280V)
- Fast Transfer Time - 10ms (PC mode) or 20ms (appliance mode) between grid and battery
- Overload Protection - 10s at 110-140% load, 5s at ≥140% load
- Wide Operating Temperature - -10°C to +50°C with 5-95% non-condensing humidity tolerance
- Built-in CC/CV Charging - 3-stage intelligent charge algorithm for both lead-acid and lithium batteries
Main Functions
- Automatic energy dispatch among PV, utility, and battery
- Supports lead-acid and LiFePO₄ battery types
- Solar charger + AC charger integrated with configurable priority and current limits
- Surge power up to 2× rated power (e.g., 6.2kW model provides 12.4kVA surge)
- Dual communication ports: RS232 + RS485 for monitoring and external control
