THIS IS A USED ITEM. Used for 3 months but had to be removed as they weren't compatible with Tesla Powerwall 3 Description Optimization is a Flex MLPE function available as an integrated modular junction box base (TS4-O) or as an add-on unit (TS4-A-O). Design using unequal string lengths, mixed orientations, or areas of mismatch. Install in shaded areas with a reduced setback ratio. In addition to optimization, the TS4-A-O enables module level monitoring, and rapid shutdown in compliance with NEC 2014, 2017, 2020. Functions Optimization Monitoring Rapid Shutdown Features and benefits Suitable for up to 700W solar modules The higher performance optimizer with Predictive IV Technology (PIV) The ONLY optimizer with selective deployment Includes the benefits of Safety & Monitoring Meets US NEC rapid shutdown requirements Optimizes right out of the box Shade and age tolerance to maximize lifetime yield Works wirelessly with the TAP & CCA Configuration 1 module per TS4 Required CCA + TAP
