PV Combiner Box

PV Combiner Box 1 String Input 1 Output, Dual 32A DC Breakers & Dual 500V/40kA SPDs

The HA-8Way-2DCB-2SPD is a 1-string, 1-output PV combiner box engineered with redundant protection. It integrates two 32A DC circuit breakers for overload and short-circuit protection and two 500V DC surge protection devices, each rated at 40kA max discharge current, for enhanced defence against lightning-induced transients. Housed in a hard, flame-retardant plastic enclosure with IP65 ingress protection, it is built for outdoor installation on both on-grid and off-grid PV systems where extra redundancy or bipolar protection is required.
