Amid the comprehensive lineup of mainstream products, ranging from PV modules, inverters, and energy storage systems (ESS) to key PV raw materials, balance of system (BOS) components often go unnoticed in a trade fair. Although these products, including AJB, combiner box, MCB, isolator, and others, are not widely promoted, their criticality in terms of a PV plant’s safety, performance, and durability can not be overlooked.
PROJOY ELECTRIC, a company focused on providing protection, safety, and metering products, showcased its latest offerings during SNEC 2025. The Chinese company’s product portfolio spans DC Isolation Switch, Miniature Circuit Breaker (MCB), DC Surge Protector, Rapid Shutdown, Micro Inverter, and Smart Electricity Meter for use in PV installation.
During the event, the company displayed its latest PERD-80 series 12-pole isolator, often required to disconnect multiple circuits simultaneously, most commonly in multi-MPPT inverters, combiner boxes, or complex PV arrays. This safety product, rated to withstand up to 1,500 V DC system voltage, can carry DC up to 88 A. The remote multipole disconnector variant, PERD-80T, was also displayed during the event.
The company also promoted its PEBS-H-50 series DC MCB, available in single pole (1P), double pole (2P), and 3 pole (3P) configurations. Rated to endure a maximum system voltage of 1,500 V DC, this product can pass through less than 50 A DC, according to the company.
Moreover, the company’s stall featured the latest PEM1LE-63 series Type B RCB (Residual Current Circuit Breaker) and PEEM-T02/T03 series smart meter.
