Sunny Central String-Monitor-US

SUNNY CENTRAL- High Tech for solar power stations

We have developed the Sunny Centrals specially for use in large PV power stations and open-field plants. Hence they possess completely special properties. String monitoring, capacity for teamwork and the ability to feed into the medium-voltage power grid make them first choice for PV systems with homogenous structure.

The Sunny Centrals are easy to install - indoors as well as outdoors. With peak efficiencies of over 98 % they belong to the most efficient central inverters on the market. maximum reliability and durability furthermore ensures the greatest investment security.

Insurance for solar yields in North America

By precisely measuring and comparing individual string currents, power deviations in the PV array are accurately detected using the Sunny Central String-Monitor-US and are analyzed in the Sunny Central inverter. According to preference, the Sunny Central String-Monitor-US is delivered in an enclosure for wall or pole mounting with degree of protection Nema 3R. For the string current measurement, there are three options of string fuse protection, all of which comply with the NEC standard, making the Sunny Central String-Monitor-US ideally suited for use in North America.

Efficient

Optimal failure detection for high yields.
A maximum of nine devices
necessary for monitoring the entire PV array.

Flexible

Three different versions
for the best possible
plant design.
Optionally suitable for installation near the coast.

Precise

DC distribution board in Nema 3R with integrated current measurement
String current monitoring with extremely high measuring accuracy (deviation < +/– 1.25 %)

User-friendly

Convenient installation preparation due to detachable side and base plates
Simple configuration of the string failure detection
