In the database, bi-polar inverters are defined by the mention "Bipolar inputs" in the technology specifities box.

With the bipolar inverters and in the system sizing tool, the voltages are clearly indicated with the +/- mention.
The number of modules in series correspond to the full voltage (i.e. 600 V for +/-300V indications).

The module Vmax should perhaps be modified. The module's datasheets usually specify that the module should not be implemented in installations overcoming 1000V. But it is not clear if this limit is applicaable to the full differential voltages in the system, or only the voltage by respect to the ground. You should contact the module's manufacturer for assessing this limit.
