For high power inverters, Panasonic introduced the HE PV type relays. This series is available in 35 A, 48 A, and 90 A types. The HE-PV has a 1FormA contact arrangement and offers a small size solution while maintaining a high capacity AC switching capability. The contacts are designed to have a 3.0 mm gap distance and to withstand 2.5 kW surge breakdown voltage which is required by Photovoltaic standard requirements. This coil holding voltage can be reduced down to 40% of the nominal coil voltage. With the solar inverter trend moving towards larger inverters to create more power generation and reduce costs, the HE-PV 90 A type provides the necessary high switching capacity and low current consumption to make this possible.
