Remember the Seinfeld episode where the rental car company took Jerry’s reservation, but still didn’t have a car for him? “You know how to take the reservation, you just don’t know how to hold the reservation. And that’s really the most important part: the holding. Anybody can just take them.” That’sRead More

When designing a large site one consideration is string or central inverters? Both have well defined benefits. Historically, the large utility-scale sites have mainly relied upon central inverters. Now a third option, the Virtual Central, is paving the way for string inverters into this space. Higher powered string inverters, longerRead More

Service models and technology at the string inverter level are vastly improved from where they were a few years ago. Earlier this week we looked at the value of choosing string inverters over central inverters for projects upward of 20 MW, thanks to 1,500-volt architecture, and then the nuances ofRead More

String inverters are now a staple of the commercial and industrial and small utility-scale segments, which was solely the domain of central inverters once upon a time. The trend started about six years ago when string inverters souped-up to 1,000 volts and developers and EPCs saw the value in chasingRead More
