Pwm Inverter (GKM Pure Power)

PWM (Pulse Width Modulation) solar inverters are a type of inverter technology used in photovoltaic (PV) systems to convert DC electricity generated by solar panels into AC electricity suitable for use in homes or to feed into the electrical grid. PWM solar inverters take the DC output from solar panels, which can vary depending on sunlight intensity and panel characteristics. In grid-tied systems, the AC output is synchronized with the grid frequency and voltage before it is fed into the grid through a synchronization process. PWM inverters still have their niche in specific applications where simplicity and cost are paramount, such as small off-grid systems or budget-conscious residential installations.

Advantages of PWM Solar Inverters

Simplicity and Reliability:PWM inverters have a straightforward design with fewer components, making them easier to manufacture, install, and maintain. This simplicity often translates to higher reliability and lower maintenance costs over the lifetime of the system.
Compatibility:They can easily replace older inverters without requiring significant changes to the existing setup, thereby reducing upgrade costs.
Suitability for Small Systems: They are suitable for small-scale residential or off-grid applications where cost-effectiveness and simplicity are prioritized.

Limitations of PWM Solar Inverters

Efficiency: PWM inverters typically have lower efficiency compared to MPPT inverters because they do not dynamically adjust to extract maximum power from the solar panels under varying sunlight conditions.
Limited Flexibility: They are less flexible in handling shading, temperature changes, and mismatched solar panel conditions, which can significantly affect overall energy production.
Voltage Compatibility Issues: PWM inverters require the DC input voltage from solar panels to closely match the inverter's input voltage rating. This can restrict the flexibility in system design and configuration.
