Miroslav S Posted July 1, 2022 Report Share Posted July 1, 2022 Dear support, I have checked rated active power of whole solar inverters such as type 36, 40, 50, 60, 100KTL. This power has been used for coefficient of overloading which suggests the software during design. But sometimes is used nominal power and sometimes is used maximal apparent power when power factor = 1. Those final active powers are different. Please unify the right calculation of overloading ratio. For example: nominal power 50kW and 60kWp of panels does overloading ratio 120% to DC site. But apparent power 55kVA (power factor 1) makes active power 55kW than overloading ratio is 109%. I am afraid to overload it correctly. Design of cables, circuit breakers is following. In fact nominal power occurs anytime but maximal power when power factor=1 occurs sometimes. Which parameter is correct technically to use? Thank you.
