Introduction
SP PRO – Three Phase Installation Notes detail the installation and additional configuration for
three SP PRO series II inverters in a three phase inverter system. One SP PRO is installed per
phase and they are interlinked and configured to allow them to operate together. The L1 phase
is the prime controller of the three phase system. It controls the operation mode of the
system, the synchronisation to the AC source, controlling of the generator etc. The L2 and L3
phase SP PROs are controlled by the L1 phase SP PRO via each unit’s SYNC interface.
