Feature of Grid Tie Micro Inverter

A GT400 Grid Tie Micro Inverter is a type of inverter designed for use in solar power systems that are connected to the electrical grid. Let’s break down the key features and functions of a Grid Tie Micro Inverter:

  1. Grid-Tie Functionality: The term “Grid Tie” indicates that this type of inverter is designed to synchronize and operate in conjunction with the electrical grid. Unlike off-grid systems that are independent, grid-tie systems allow the solar power system to work alongside the conventional utility grid.
  2. DC to AC Conversion: The primary function of a Grid Tie Micro Inverter is to convert the direct current (DC) generated by solar panels into alternating current (AC), which is the type of electricity used in homes and fed into the grid.
  3. Single-Panel Control: Grid Tie Micro Inverters are often designed to connect to individual solar panels. Each inverter is paired with a specific solar panel, allowing for independent operation and optimization of each panel’s power output.
  4. Maximum Power Point Tracking (MPPT): Many Grid Tie Micro Inverters incorporate Maximum Power Point Tracking (MPPT) technology. This technology adjusts the electrical operating point of the solar panels in real time, ensuring they operate at their maximum power point under varying environmental conditions.
  5. Efficiency: Grid Tie Micro Inverters contribute to the overall efficiency of a solar power system. By converting DC to AC at the panel level and allowing each panel to operate independently, they can mitigate losses associated with shading or differences in panel performance.
  6. Grid Interaction: One of the key advantages of grid-tie systems is the ability to interact with the electrical grid bidirectionally. Excess energy generated by the solar panels can be fed back into the grid, and when the solar panels produce less power (e.g., during the night), electricity can be drawn from the grid.
  7. Net Metering: In many grid-tie installations, net metering is utilized. Net metering allows homeowners or businesses to receive credit for the excess electricity they generate and feed back into the grid.
  8. Wireless Control: Micro-inverters are operable and monitored via WiFi or a mobile app, enhancing overall efficiency.
  9. Safety Assurance: Microinverters ensure safety by independently controlling each component, providing IP66 protection against rainwater, and minimizing safety risks with parallel connections.
  10. Easy Installation: Micro-inverters can be installed directly behind the module or on a bracket, supporting stackable connections, high-precision phase detection, and protection mechanisms for over-voltage, under-voltage, over-frequency, under-frequency, and islanding. Minimal maintenance is required, typically limited to occasional dust removal from the photovoltaic module.


GT400 Grid Tie Micro Inverters are commonly used in residential and commercial solar installations where the goal is to harness solar energy efficiently while maintaining a connection to the utility grid for continuous and reliable power supply. Some common applications are listed in the following:

  • Eco-Friendly Household Power: Supply clean energy for homes.
  • Commercial Electricity Conversion: Transform solar energy into commercial electricity for businesses.
  • Agricultural Applications: Empower agriculture with solar energy for irrigation and livestock.
  • Electrical Appliance Support: Provide power for individuals using electrical devices.
  • Municipal Road Lighting: Contribute to road lighting in municipal projects.
  • Lighting with Solar Energy: Utilize solar power for lighting, promoting energy efficiency and emissions reduction.
