The Solar. Edge Solution

Traditional Inverters - Limitations Energy Loss & Maximum Power Point Tracking (MPPT) Traditional string inverters find the point of maximum power output at the string level, not at individual module level This prevents modules from reaching their maximum production potential Limited design flexibility String design restrictions significantly limits system layout and size Low resolution monitoring No data on module performance Safety hazards High voltages at the module level even when inverter or AC power is off 8

The Solar. Edge Solution Split the traditional inverter functionality into two: The power optimizer to maximize energy production for each module A simplified inverter responsible for DC-AC inversion and grid management Power Optimizer Fixed Voltage Inverters Monitoring Platform 9

So why does Solar. Egde need ASICs?

IP Design Challenges for Renewable Energy App. Extreme harsh environment Very high level of emission/EMI noise Very wide range of input/output signals No off-the-shelf standard analog IPs designed for renewable energy applications Digital control loop requires predicted minimum response time quality of service The system knowledge is spread over several disciplines: Power (AC and DC) Algorithms Communication (PLC & wireless) Embedded SW 19

What do we gain from in-house ASICs? The main reasons for developing in-house ASIC are: Reliability Performance IP protection Price Supply chain Time to market 20

Reliability Product lifetime is 25 years Technology choice Package system reliability Architecture and system partitioning Design rule + Design margins In-house qualification process and very strong QA team 21

Performance Trade-off between reliability and performance Digital power implementation require infinite CPU bandwidth Silicon process reliability and high voltage requires us to stay in “mature” node technologies System requires state-of-the-art high precision analog IP targeting renewable energy applications The Solution New architectural approach based on real time reconfigurable HW and proprietary CPU architecture Developing in-house high precision analog FE architectures targeting renewable energy applications 22
