SolarEdge wrote:Inverters are the “brain” of the solar energy system, because they convert solar power into usable energy and are measured by size, efficiency, and reliability. While advances have been made in the solar inverter space throughout the years, the large size of magnetics and cooling components have significantly limited any leapfrogging in the inverter space. SolarEdge’s new HD-Wave technology will dramatically reduce the size of the inverter's magnetics by means of advanced digital processing. At the same time, the new technology is designed to increase reliability and optimize the performance of solar energy systems to 99% efficiency and beyond, an increase that will provide more solar power at lower cost.
I'm wondering if this inverter is designed to meet Google's $1M Little Box Challenge. Winners of the challenge will be announced in January, 2016. Here are the specifications for the Little Box Challenge:
Google wrote:- Must be able to handle up to 2 kVA loads
- Must achieve a power density of equal to or greater than 50 W/in3
- Must be able to handle loads with power factors from 0.7–1, leading and lagging in an islanded mode
- Must be in a rectangular metal enclosure of no more than 40 in3
- Will be taking in 450 V DC power in series with a 10 ohm resistor
- Must output 240 V, 60 Hz AC single phase power
- Must have a total harmonic distortion + noise on both voltage and current of < 5%
- Must have an input ripple current of < 20%
- Must have an input ripple voltage of < 3%
- Must have a DC-AC efficiency of greater than 95%
- Must maintain a temperature of no more than 60°C during operation everywhere on the outside of the device that can be touched.
- Must conform to Electromagnetic Compliance standards as set out in FCC Part 15 B
- Can not use any external source of cooling (e.g. water) other than air
- Does not require galvanic isolation
In any case, SolarEdge's new inverter technology looks like it may be a significant breakthrough.
