The ability to reduce the maximum AC power rating of an inverter, also referred to as inverter power derating, allows solar installers to set the AC power rating of an inverter during commissioning when precise system power targets are required.
The efficiency of an inverter, which determines how much of the DC power generated by a solar array is converted to AC power, is generally not a fixed value.
Balance-of-system efficiency; typically, 80% to 90%, but stipulated based on published inverter efficiency and other system details such as wiring losses.
IEC 62891:2020 provides a procedure for the measurement of the efficiency of the maximum power point tracking (MPPT) of inverters used in grid-connected photovoltaic (PV) systems. Both the static and dynamic MPPT efficiency are considered.
It requires around 30-40 solar panels (300-400W) and a $30,000-$40,000 investment to set up a 12kW solar system. But before building a 12kW solar system, you must account for multiple factors like your energy usage, roof space, location, and others.
The maximum power the inverter can supply indefinitely under rated operating conditions. It is determined primarily by: Continuous power is fundamentally a thermal constraint, not an electrical peak limit.
To protect solar inverters from lightning damage, install appropriate Surge Protection Devices (SPDs) 1 on both AC and DC sides of the system. Select SPDs with voltage ratings matching your system's maximum voltage, and ensure they're properly grounded.
In this video, the Blue Ape Renewables team provides a complete guide on safely removing and relocating a solar inverter to keep your solar PV system running efficiently.

Essentially, the inverter's input voltage range must be compatible with the solar panels' output. Most residential panels generate between 12-40 volts DC under regular operational conditions, while larger commercial systems might demand inverters that handle from 400 volts up to.
