I can’t allocate my panels to an inverter - all the options are red.

When all of the allocation options are red, Easy PV has determined the panel/inverter combination is not electrically viable. This means that the technical specifications of either the panels or the inverter are out of the range of the other.

Easy PV will outline any electrical issues in red text to make you aware of why it is not compatible. For a custom component this could mean one of the values you have input is incorrect so it may be worth reviewing the datasheet and cross referencing with our component upload guide.
