Low-frequency inverters are generally larger, heavier, and more expensive than their high-frequency counterparts. They are commonly used in applications where reliability, robustness, and battery management capabilities are crucial, such as remote off-grid locations, rural electrification projects, and critical backup power systems.

They are most ideal in areas with appliances which have induction loads like pumps, motors or heaters.

It's always recommended to consult with a solar energy professional or installer to determine the most suitable inverter type and configuration for your specific solar power system requirements.
