Vidokezo vya kuchagua vibadilishaji vya mwanga wa voltaiki

  1. Confirm what power inverters are suitable for installing in your photovoltaic power station
    The installation capacity of a general power station is calculated based on the land or roof usage area, taking into account factors such as tilt angle and bracket installation method, with the principle of minimizing shading as much as possible.
  2. Investigate how many MPPT and input channels the inverter has
    The number of MPPT channels in an inverter largely determines the power generation of a photovoltaic power station, and the number of input channels in an inverter often determines whether a photovoltaic power station is easier to design and save auxiliary materials such as cables.
  3. Protection issues
    The basic protection functions of grid connected inverters include input overvoltage and undervoltage protection, input overcurrent protection, short circuit protection, overheating protection, and lightning protection; Grid protection includes: output overvoltage protection, output overcurrent protection, over frequency and under frequency protection, and anti islanding protection.
  4. Heat dissipation solution
    At present, there are three common cooling methods in the industry: forced air cooling, natural cooling, and water cooling. Among them, water cooling is mainly used for large centralized inverters and is less commonly used. From the perspective of inverters, household single-phase inverters have lower power levels, less heat dissipation, and are used in households.
  5. Overmatch capability
    The overshoot capability of inverters is generally related to the number of input channels and the maximum DC input power that can be supported by the machine. Currently, regular brand inverters reserve some overshoot margin in their design, usually around 1.1 times.
