transformer reverse power

[lpcb]

Dear Engineers,
we have the following case:
we are in middle of design the on grid PV system (350 KWp)and the utility forced us to connect the system on LV side of distribution transformer ( 400 KVA , 33/0.4 kV) the max. daily peak load of the transformer is 370 KVA and the reverse power to MV grid is allowed:
my question: does the transformer have a reverse power capacity limit or it is the same in both flow direction?

It should be same. Two winding 400 KVA 33/0.4 kV transformer will have 400KVA rating for 33kV winding and 400KVA rating for 0.4kV winding (marked on rating plate).
