1. Classification by Output Waveform
• Pure Sine Wave Inverter: Output waveform closely resembles AC mains power, suitable for equipment with high power quality requirements (such as precision instruments and medical equipment).
• Modified Sine Wave Inverter: Output waveform is between a sine wave and a square wave, lower cost, suitable for simple loads (such as lighting fixtures and fans).
• Square Wave Inverter: Output waveform is a square wave, lowest efficiency, only suitable for a few simple devices (such as resistive loads).
2. Classification by Application Scenarios
• Photovoltaic Inverter: Designed specifically for solar power systems, used to convert DC power generated by photovoltaic panels into AC power for grid connection or local use.
• Vehicle Inverter: Converts 12V/24V DC power from a car battery to 220V AC power for vehicle electrical appliances.
• Home Inverter: Used in home backup power systems, working with battery packs to provide power support during power outages.
• Industrial Inverter: Used in industrial equipment or large power systems, featuring high power and strong stability.
3. Classification by Grid Connection Method
• Grid-connected inverters: Connected to the power grid, converting direct current (DC) to alternating current (AC) and feeding it into the grid. Commonly found in photovoltaic (PV) or wind power systems.
• Off-grid inverters: Operate independently, not connected to the power grid. Suitable for remote areas or independent power supply systems.
• Hybrid inverters: Combine grid-connected and off-grid functions, allowing for flexible switching between operating modes.
