    Inverter Selection & Site Conditions

    Choose the right inverter based on your site characteristics

    ✓ Good Choice

    • • All-In-One (AIO) inverter recommended for battery systems
    • • Built-in MPPT avoids double inverters (panels + battery)
    • • No shading issues detected

    When to use each type:

    AIO Inverter (Battery Systems): All-In-One inverters include built-in MPPT charge controllers. Avoids double inversion for maximum efficiency.

    String Inverter (No Battery): Requires separate charge controller. Cost-effective for grid-tie without storage.

    Microinverters: Best for shading with NEM, mixed orientations, or expanding maxed-out string inverter via gen port.
