µ-parallel inverters are the solution when maintenance µ-parallel inverters are the solution when maintenance and cabling, and hardware costs are the driving factorand cabling, and hardware costs are the driving factor
• No need for DC combiner's• No need for Optimizer's• Graceful degradation when panels fail• DC optimizers on each panel provide
the smart data to a string array but increase installation labor and H/W
• Simplified low voltage AC cabling• Self mapping array automatically maps
inverter location to their physical location in the grid map. DC Optimizers mounted on each panel require manual mapping.
• Time saving during installation• Eliminates “hunting the field” for the
failed inverter or panel if mistakes occurred during a manual mapping..
• Intelligent alerts diagnostics and prognostics
• Field reparable components

Three types Micro Grids can be constructed with Smartphase™
1. Off grid• Provides power to a building with out connection to a utility power grid.• Requires generator to serve as the grid (fueled or battery).• If battery powered a fueled generator is recommended to recharge the batteries
should inclement weather prevent timely recharging.
2. Grid tied• Provides supplements solar power to a building that is tied to the utility power grid.• Anti islanding circuits shuts off the inverters when the grid fails or browns out.
• Senses power resonances and shuts the system down.• critical safety feature that allows power crews to safely work on restoring power and prevents the
3. Grid tied with automatic emergency power• A grid tied system with automatic transfer switches automatically disconnects from
the grid when the grid voltage drops below a set level and then turns on a battery powered wave form generator of the same size as the anticipated load that allows the grid tied system to behave as an off grid system
• Requires a wave form generator of the same size as the anticipated load that is incorporated into an off grid only inverter or a separate wave form generator where the inverter can be used in a grid tied application.
