SolarBOS Announces Fused AC Combiners

[Livermore, CA] Balance of system product developer SolarBOS has launched fused ac combiner and recombiner solutions for commercial, industrial and utility-scale PV plants. SolarBOS designed the products to facilitate the aggregation of the ac output for multiple-string inverters. Fuse-based combiners offer some distinct advantages over breaker-based products. Fused products can offer better performance at elevated temperatures, thereby reducing nuisance trips. Current-limiting fuses reduce arc flash energy by a factor of 5–10 and the level of PPE required during equipment servicing. Additionally, many string inverters include load-break–disconnecting means. This allows the use of non–load-break fuseholders to isolate inverters, which can result in significant cost savings.
