While both microinverters and power optimisers are used in solar energy systems to improve efficiency, they operate in different ways. Below we highlight the differences and similarities between the two products.
Microinverters:
- Function: Microinverters convert DC (direct current) electricity generated by each solar panel into AC (alternating current) electricity.
- Placement: They are installed on each individual solar panel.
- Performance: Since each panel operates independently, if one panel is shaded or underperforming, it won’t affect the performance of the others.
- Monitoring: They typically allow for detailed monitoring at the panel level.
Power Optimisers:
- Function: Power optimisers also work to maximize the output of each solar panel, but they do not convert DC to AC; instead, they condition the DC power before sending it to a central inverter.
- Placement: Optimisers are attached to each panel, but the actual inversion (conversion to AC) happens at a central inverter.
- Performance: Similar to microinverters, power optimisers allow each panel to operate optimally, minimizing the impact of shading or other issues on the overall system.
- Monitoring: They provide monitoring capabilities, often at the panel level as well.
Summary:
- Microinverters: Convert DC to AC at each panel; operate independently.
- Power Optimisers: Enhance panel performance before sending DC to a central inverter; also allow for panel-level monitoring.
Both technologies improve energy harvest from solar panels, especially in systems where shading or panel mismatch is a concern.
