Zettler Solar Relays – Relays built for photovoltaic systems
In photovoltaic inverters, relays connect the system to the grid and disconnect it safely when required. They must carry high currents continuously, withstand high voltages and work reliably for many years under demanding temperature conditions. ZETTLER has developed its solar relays specifically for these requirements of the PV industry.
The range covers a broad power spectrum, from the AZ SR131 at 35 A to high current types such as the AZ SR190 rated for 90–100 A and the AZ SR1160 with 160 A continuous current. This means suitable relays are available for small residential inverters as well as larger commercial systems.
