If all the 120 VAC loads have their neutrals land in the main meter panel then there is no need to run a neutral from there to the sub panel, as long as the inverter does have a neutral connection back to the meter panel. </div>

Especially when the inverter goes off grid it needs that neutral connection to the loads neutral in the meter panel. </div>
