In the realm of photovoltaic and renewable energy systems, the Series 67 solar relay from FINDER stands as a robust and specialized switching device designed for DC applications up to 50 A. This component is engineered to handle the high inrush currents and continuous loads typical of solar panel arrays and battery storage systems. It features a compact, modular design with a rated operational voltage of up to 400 V DC, ensuring reliable isolation and switching under demanding conditions. The relay incorporates a bi-stable (latching) mechanism, which minimizes coil power consumption and heat generation, a critical advantage in energy-sensitive installations. Its construction includes reinforced insulation and a high degree of protection (IP 40 or higher), making it suitable for integration into distribution boxes and inverter cabinets. Technically, it is a single-pole (1P) device, optimized for DC-1 and DC-21 utilization categories, and is often paired with dedicated sockets and accessories for secure mounting and wiring.
These solar relays are predominantly deployed in photovoltaic systems, including grid-tied and off-grid installations, where they serve as the primary switching element between solar panels and inverters or charge controllers. They are also found in large-scale battery energy storage systems (BESS), where they manage the connection and disconnection of DC circuits. Beyond solar, they are utilized in industrial DC power supplies, uninterruptible power supplies (UPS), and electric vehicle charging stations, where high-current DC switching is required. Their robust design ensures they can withstand the thermal and electrical stresses of continuous operation in outdoor or semi-outdoor environments, often within IP65-rated enclosures.
Within this category, the primary subcategory is the Series 67 solar relay itself, typically identified by codes such as 67.22.9.012.4000 or 67.22.9.024.4000, where the digits indicate the coil voltage (e.g., 12 V DC or 24 V DC) and the contact configuration. The code structure generally follows the pattern: 67.XX.X.XXX.XXXX, where the first two digits after the series denote the number of poles and contact material, and the subsequent numbers specify the coil type and packaging. Key articles include the 67.22.9.012.4000 (12 V DC coil, 50 A contacts) and the 67.22.9.024.4000 (24 V DC coil, 50 A contacts). Accessories like the 67.99.0.000.0000 socket and 67.99.9.024.0000 coil suppression module are also available to complete the installation.
