Microinverters convert DC to AC at each panel, offering advantages for balconies where shading, variable orientations, or space constraints reduce the effectiveness of string inverters.
Advantages:
Microinverters can be slightly more expensive per watt than a single string inverter, but the performance gains on shaded or non-uniform balcony installations often justify the cost. They also simplify AC-side wiring and safety because output is already at household voltage. For many balcony and patio systems, microinverters provide a reliable, efficient solution that adapts well to constrained or irregular spaces.
