To choose the right solar panel inverter, it's important to consider the solar panel arrays' maximum power output and select an inverter with the correct size, model, and type. Avoid excessive clipping by ensuring the DC system size is about 1.2 times greater than the inverter's max AC power rating. It’s normal for the DC system size to be larger than the inverter system's max AC power rating.
The design of solar panel strings needs to satisfy two conditions simultaneously: The maximum open-circuit voltage of the series-connected photovoltaic modules should be lower than the inverter's maximum input voltage. The MPPT voltage of the series-connected photovoltaic modules should fall within the inverter's MPPT voltage range.
Rated Voltage and AC Voltage Relationship: For a 230V grid connection, the rated voltage is generally around 360V. For a 400V grid connection, the rated voltage is generally around 580V. For a 480V grid connection, the rated voltage is generally around 700V. The design of solar panel strings needs to satisfy two conditions simultaneously:
When designing strings, the electrical parameters of the modules are typically chosen under STC conditions. The standard test conditions for solar panels are: Air Mass AM1.5, solar irradiance 1000W/m², and cell operating temperature 25℃. The temperature coefficient of the open-circuit voltage (Kv) of the module is a negative value.
Typically, inverters operate most efficiently near the midpoint of their MPPT range. Given that the optimal operating voltage is around 600V, we use the module's peak power voltage (Vmp) to determine the number of modules needed to reach this voltage. For a 420W module, Vmp is typically around 35-38V.
The closer the inverter's operating voltage is to the rated operating voltage, the higher the generation efficiency. Operating Voltage and Conversion Efficiency: The conversion efficiency of an inverter is influenced by the operating voltage. Efficiency decreases when the operating voltage is either too low or too high.
