Enphase 215 Watt Utility-Interactive Inverter with integrated GFDI M215-60-2LL-S22-ZC - used Enphase 215 Watt 208/240 VAC Micro Inverter Designed for installations using Zep racking. Model M215-60-2LL-S22-ZC Series M215 Manufacturer Enphase Energy Features Maximum energy production Resilient to dust, debris and shading Performance monitoring per module System availability greater than 99.8% No single point of system failure Quick and simple design, installation and management 24/7 monitoring and analysis Low voltage DC Reduced fire risk Detailed Description Enphase's simple innovation is to place a single inverter on each solar panel instead of using a single, massive inverter for an entire array. Improved overall efficiency is just one of the host of benefits of per-panel solutions like these "micro inverters": they also significantly reduce the impact of shading issues and are budget-friendly, allowing a system to be built literally a panel at a time. The M215 is the latest in Enphase's line of micro inverters. Smaller and more efficient than its predecessors, the M215 reduces overall cost by shifting some of its burden towards the specially designed "Engage" cabling system. This product works with 60-cell solar modules only. SHELF: WH73
