Yaskawa Solectria CR1500-28-20S 1500VDC 20A Fuse Remote String Combiner

Yaskawa Solectria Solar 1500VDC 28-String Remote PV Combiner Box

The Yaskawa Solectria CR1500-28-20S is a high-voltage remote PV string combiner box engineered for utility-scale and large commercial ground-mount solar arrays. Designed to consolidate output from multiple solar module strings into main DC feeders before connection to central inverters, this combiner box features an integrated load-break DC disconnect switch and factory-installed DC surge protection to safeguard downstream equipment against transient voltage spikes.

Constructed with a heavy-duty, powder-coated aluminum enclosure rated for harsh outdoor environments, the unit ensures corrosion resistance and thermal management under direct sun exposure. Pre-configured touch-safe fuse holders and internal busbaring simplify field landing for array conductors, streamlining jobsite installation labor while maintaining high system reliability.
