1. String inverter - Converts DC to AC for a string of panels• High voltage DC inputs• Largest in class• Conveniently placed near the service box• PV panels are connected in series. Voltage builds with each panel. • MPPT tracking for the string• Smart Data limited to an average across the string• String inverter with digital optimizer- adds a component to each panel to provide smart data, and improved MPPT

• Size of a micro inverter (small cigar box) Mounted like a micro inverter• Provides MPPT tracking and Smart data for each panel• Power generation continues with the loss of any given panel• The string can drop out if an optimizer fails• PlCC communications

2. Micro- Parallel inverter - Converts DC to AC for up to 4 panel • Low Voltage DC voltage inputs < 50V• Each panel handled as an individual• Medium sized (Width of a panel, (designed for single handed blind tool less installation and removal))• Conveniently located as desired ( Panel, frame, or near service box)• MPPT tracking of the inverter for each panel• Smart data to the individual inverter and panel• Intelligent alerts emailed to the maintainer/owner isolates failure to panel or inverter. • Graceful degradation ( continues to operate with as few as 1 panel powering the inverter)• Thermal survival mode (throttles power generation to survive abnormal ambient temperatures)• Remote power throttling by the owner/ or power authority to mitigate over production

Micro parallel inverters are a new class of Inverter


3. Micro Inverter - Converts DC to AC for each panel• Low Voltage DC voltage inputs < 50V• Size of a small cigar box• Mounted on the panel or just below it on the frame• MPPT tracking of the inverter for each panel• Smart data to the individual inverter and panel• Power generation continues with the loss of any given panel4. Micro- Parallel inverter - Converts DC to AC for up to 4 panel with each panel handled as an individual• Low Voltage DC voltage inputs < 50V• Medium sized (Width of a panel, (designed for single handed blind tool less installation and removal))• Conveniently located as desired ( Panel, frame, or near service box)• MPPT tracking of the inverter for each panel• Smart data to the individual inverter and panel• Remote password secured activation and termination by the owner• Autonomous monitoring and alerts• Intelligent alerts emailed to the maintainer/owner isolates failure to panel or inverter. • Graceful degradation ( continues to operate with as few as 1 panel powering the inverter)• Thermal survival mode (throttles power generation to survive abnormal ambient temperatures)• Remote power throttling by the owner/ or power authority to mitigate over production

• 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.
