Should we all go for active filtering?

The transformer has a capacity of 1250 KVA, with an installed capacity of 2100 KW; the coefficient of simultaneous use is around 0.4. The 2000 KW figure refers to that of the inverter. An electrical active power filter with a capacity of 400A has been installed, but the owner is unwilling to invest in it. Do you think it should be installed?
Add inlet and outlet reactors to the inverter
Active power filters are capable of compensating for harmonics whose magnitude and frequency vary, as well as for changing reactive power, thereby enabling dynamic tracking compensation; they can compensate both for harmonics and for reactive power.
If the line condition is good, it’s not necessary to use it. If the line isn’t working properly, it’s advisable to add it anyway to avoid fines later on
If there are many circuits in the inverter, harmonics will be generated; it’s better to install one
