Low voltage guidelines in a growing number of European countries stipulate the deployment of external interface switches or substations from 30 kVA upwards. Cost wise, this can easily run into four-figure sums for material, installation and operation.
However, this is not the case with the Powador and blueplanet string inverters: section switches are already built into all devices as standard! You only need the Powador-protect which directly controls these internal switches. For EPCs, specifiers and designers of PV installations this means simple, no-risk calculations, and no hidden additional AC hardware costs and recurrent operating expenses. Using Powador-protect means an immediate alternative to more expensive safety switching, meeting all the common norms.
On top of that, Powador-protect evaluates the signals from ripple control receivers and transmits these to up to 31 inverters. The Powador-protect itself can be quickly installed, is easy to handle and is therefore the most economic solution on the market.
