ACRak 320 Microinverter Installation Solution
Model Number: ACRak 320
The ACRak Microinverter Installation Solution combines Darfon G320 microinverters with IronRidge XR rails to create an easy-to-install, out-of-the-box solution.
Darfon’s AC Rak’s locking cable connectors and XR100 splices eliminate the need to cut rails, install cabling or mount microinverters, saving time and money. Now, building a solar array is as simple as mounting and grounding rails, connecting sections and mounting the panels of your choice. AC Rack Specifications Data Sheet
