Product Application

• Grid-Tied Solar Inverters:

  • Used to convert DC power generated by solar panels into AC power that can be fed into the electrical grid.

• Off-Grid Solar Inverters:

  • Powers standalone systems by converting solar energy into AC power for use in homes or remote locations without grid access.

• Battery-Based Systems:

  • Integrated into systems that charge batteries with solar energy, providing power during non-sunny periods.

• Microinverters:

  • Employed in small-scale solar installations, converting DC to AC at the panel level to optimize energy harvest and efficiency.

• Power Optimizers:

  • Work alongside solar panels to maximize energy output by managing and converting power at the module level.

• Hybrid Inverters:

  • Combine functionalities of grid-tied and off-grid systems, allowing for energy storage and load management.

• Solar Monitoring Systems:

  • PCBAs in monitoring devices track performance and efficiency of solar power systems, providing real-time data to users.

• Smart Home Integration:

  • Used in inverters that connect with home automation systems for energy management and optimization.

• Electric Vehicle Charging Stations:

  • Integrated into solar-powered EV charging solutions, converting solar energy for use in electric vehicle charging.

• Renewable Energy Systems:

  • Part of larger renewable energy setups, working with other technologies like wind energy systems to provide reliable power.
