PV inverters convert and control solar generation within a specific electrical system. String, central, micro, hybrid and off-grid products have different interfaces and operating assumptions; their labels do not establish interchangeable capabilities.

Check DC voltage windows, input current, MPPT arrangement, AC voltage, frequency, phase and continuous output together. Battery support, island operation, backup switching and export control require model-specific confirmation.

Efficiency figures, protection ratings and grid-support functions should be read with their test conditions and destination requirements. A certificate named in promotional material is not proof that every model or regional configuration is covered.
