showing error 90

Fault code 90 means that the firmware thinks that it is running illegally on a clone. At least, that's what it means for Axperts (off grid models; Infinis are called on-grid models by Voltronic).

If it's the same as with Axperts, you need either patched firmware (most unlikely for Infinis), or you have to get an updated firmware or serial number updating tool from your inverter supplier.
