ProHarvest by OutBack > ProHarvest 480V Commercial String Inverter
3-phase 480V String Inverter for Commercial applications
Designed for reliability, the ProHarvest 480V String Inverter (PRO480-8k) is an easy to install,
modular system optimized specifically for commercial rooftop ungrounded solar array applications.
Unlike other string inverters, each string is individually monitored and managed by the inverter.
Inverter AC cables must be ordered separately.
