Description

Off-grid hybrid inverter, pure sine wave, 60-500V PV, MPPT, Li-activation, battery-less

Off-Grid Hybrid Inverter with Pure Sine Wave Output

Advanced off-grid hybrid inverter featuring pure sine wave output, wide 60-500V PV input range, built-in MPPT technology, lithium battery activation capability, and battery-less operation for versatile power solutions.

Key Advantages

Lithium Battery Activation via PV or Utility - Revives deeply discharged Li-ion batteries, preventing premature disposal and extending battery life
Operates Without Battery - Functions grid-connected or directly from PV, reducing initial costs for budget-conscious off-grid installations
Pure Sine Wave Output - Delivers clean power for all load types including inductive/capacitive loads, air conditioners, refrigerators, and motors
Power Factor 1.0 - Provides 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 across different usage scenarios
Battery Equalization (EQ) - Optimizes battery bank performance and extends cycle life
Detachable Dust Cover - Easy cleaning maintenance, ideal for harsh and dusty environments
Optional WiFi Remote Monitoring - Real-time system status monitoring via smartphone or PC

Advanced Features

LiFePO₄ Communication via RS485 - Intelligent BMS interaction for safe and efficient charging/discharging
Dual-Source Charging - PV + AC grid delivers 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

Primary Functions

Automatic energy dispatch among PV, utility, and battery sources
Supports both lead-acid and LiFePO₄ battery types
Integrated solar charger and AC charger 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 comprehensive monitoring and external control
