I. General Core Characteristics

1. High-efficiency Energy Conversion

    

   Convert photovoltaic direct current (DC) into alternating current (AC) with a conversion efficiency of 97%–99.5%. MPPT maximum power tracking technology effectively improves power generation output.
    
2. MPPT Maximum Power Point Tracking

    

   Real-time tracking of changes in light intensity and temperature. Inverters with multiple MPPT channels (string/micro type) perform better in resisting shading and module mismatch loss.
    
3. Dual Grid-tied / Off-grid Mode
    

• Grid-tied type: Synchronize with grid frequency and phase, equipped with anti-islanding protection, allowing surplus power to feed into the grid.
• Off-grid type: Matched with energy storage batteries for independent power supply, ideal for areas without grid coverage.

4. Comprehensive Safety Protection

    

   Built-in overvoltage, overcurrent, overload, leakage current and anti-islanding protection with millisecond-level response. String and micro inverters support module-level rapid shutdown.
    
5. Intelligent Monitoring & Operation Maintenance

    

   Support data collection, remote communication, fault alarm and power generation optimization, adapting to unattended operation.
    
6. Strong Environmental Adaptability

    

   Wide operating temperature range (-30℃～+60℃), dustproof, moisture-proof and salt spray resistant, suitable for desert, coastal and plateau areas.

Pure Sine Wave Vehicle-mounted Inverter

• Pure Sine Wave Vehicle-mounted Inverter: Converts DC power from 12V/24V vehicle batteries into 220V pure sine wave AC power, for powering small electrical appliances inside the vehicle or outdoors.
• Ordinary Solar Inverter: Converts DC power generated by solar panels into 220V AC power, for household use or grid connection. Most models adopt pure sine wave output, while a small number of low-cost ones are modified sine wave.

1) Output Waveform (Core Difference)

• Pure Sine Wave Vehicle-mounted Inverter:

  

  Adopts pure sine wave output, identical to household mains power, with THD＜3%.

   

  ✅ Compatible with laptops, cameras, refrigerators, medical devices, audio equipment, etc. No noise, no abnormal heat generation, and no damage to electrical appliances.

   
• Ordinary Solar Inverter:
   
  • High-quality models: Pure sine wave (the mainstream type for household and grid-connected use).
  • Low-cost models: Modified sine wave (stepped square wave).
     
    ⚠️ Modified sine wave will cause overheating of precision equipment, buzzing noise of audio, reduced motor efficiency and shortened service life.
   

2) Input Voltage (Applicable Power Source)

• Pure Sine Wave Vehicle-mounted Inverter: Fixed 12V/24V DC input for vehicle batteries, with a general power range of 150–2000W.
• Solar Inverter: Connected to photovoltaic panels, with a wide voltage range (e.g. 24V–600V DC). Equipped with MPPT maximum power point tracking function to automatically track sunlight and improve power generation efficiency.

3) Functional Design

• Vehicle-mounted Inverter
   
  • Compact and portable design for vehicle use, powered via cigarette lighter socket or battery clips.
  • Multiple protection functions: low voltage, overvoltage, overload, overheating and short circuit protection.
  • No MPPT function, only responsible for DC-AC inversion.
   
• Solar Inverter
   
  • Outdoor waterproof design, supporting grid-tied, off-grid and hybrid modes.
  • Hybrid models integrate MPPT charging, inversion, grid metering and energy storage management functions.
  • Surplus power can be fed back to the public power grid for earnings.
   

4) Application Scenarios

• Pure Sine Wave Vehicle-mounted Inverter

   

  ✅ Road trips, camping, power supply for trucks and RVs, power supply for precision equipment.
   
• Ordinary Solar Inverter

   

  ✅ Household rooftop photovoltaic systems, small power stations, long-term off-grid power supply.
   

• One-sentence Summary

• Pure Sine Wave Vehicle-mounted Inverter: Converts 12V battery DC power to 220V pure sine wave AC power. It features low power and portability, suitable for vehicle-mounted and outdoor power supply for precision equipment.
• Ordinary Solar Inverter: Converts power from photovoltaic panels to 220V AC power, built with MPPT function, high power and grid-connectable. Low-cost models are modified sine wave, which is not recommended for precision equipment.
