The rated operational voltage of the Isolator should be equal to or greater than the requirements of the system. Common are to meet the UL508i 600V, IEC60947-3 1000V and 1500V. Typically the system voltage connected to single-phase inverters is up to 600V, three-phase string inverters or centralized inverters up to 1000V or 1500V.
For built-in DC Isolators, the number of MPPT's of the inverter determines the poles of a DC Isolator. Common string inverters are with a single MPPT, dual MPPT's and a few, triple MPPT's. Generally speaking, an inverter, power rating at 1kW ~ 3kW, is designed with single MPPT; 3kW ~ 30kW with dual MPPT's or few triple.
For external DC Isolators, you can choose 4 Pole, 6 Pole, 8 Pole for multi-string solar panels or select 2 Pole for one string of solar panel, based on the different system design.
