9. Briefly describe the various technologies and its suitable applications such as Central Inverter, String, Micro Inverter, 1500V, Outdoor, Container solutions etc..The SolarEdge commercial DC optimized inverter solution consists of inverters, power optimizers, and a cloud-based monitoring platform. The technology provides superior power harvesting and module management by connecting power optimizers at the module level. The ability to connect two modules to one optimizer, combined with DC to AC conversion and grid interaction being centralized at a simplified PV inverter maintains a competitive cost structure. SolarEdge DC optimized inverters are robust for tough environments and can be installed outdoors. Using a fixed-string inverter, SolarEdge DC optimized inverters already offer longer strings, up to 15.3kWp per string, which leads to a significant reduction in BoS costs compared to both traditional string inverters and 1500V systems. While the module-level, remote monitoring platform improves O&M and PV asset management by allowing real-time insight into system performance and the ability to perform remote maintenance.
Based on SolarEdge’s track record of optimizing commercial-scale PV systems, SolarEdge recently launched larger-capacity, three-phase inverters up to 100kW. These new commercial inverters offer the benefits of both central and string inverters, but without any of the setback, such as needing a forklift, requiring a specialized team for maintenance, increased system downtime. With simple and cost-efficient installations, pre-wiring, and easy maintenance, the larger-capacity inverters save on AC BoS costs and can minimize downtime to the  impacted string. In addition, the new inverters provide smart energy management control.
10. How much is your R&D budget as % of your sales / profits

11. What are the top 5 markets for your company in the past, present and future
The North American market is our largest market, with approximately 60% of our revenue coming from our North America sales. Following the North American Market, are the European and Australian markets.
12. Technology road map in terms of 1500V , micro inverters, upcoming game changes technologies
SolarEdge already offers longer strings, up to 15.3kWp per string, which leads to a significant reduction in BoS costs compared to both central and string inverters and 1500v systems.SolarEdge’s DC optimized inverter solution offers longer strings with fixed-string voltage. Fixed-voltage mode is an advanced operating mode for string inverters. It requires power optimizers to match current level drawn from the inverter, while the inverter maintains string voltage at optimal voltage for DC/AC conversion – regardless of string length or temperature. This means that string length is no longer governed by voltage, but by power. And in fact, it allows for 100% longer strings than standard string inverters, while also keeping the voltage below 1000v– which means specialized 1500 hardware is not required.
SolarEdge developed and continues to be the leader in the DC-DC optimization market.
SolarEdge recently developed and began sales of its HD-Wave inverter. The As the winner of the prestigious 2016 Intersolar award, the HD-Wave inverter breaks the mold of traditional inverters.
