PSSB PV Array Disconnect The PSSB PV array disconnect designed specifically to work with the SMA Sunny Boy line-tie inverter systems. It can also be used with other high voltage utility interactive PV inverters or other applications such as large inverter power systems or water pumping systems, etc. Can also be used as a standard 600 vc disconnect for a single high voltage PV array. Standard Features and Components Outdoor, rainproof powder coated aluminum enclosure- can be installed on vertical or sloped surfaces down to a 3/12 pitch (14 degrees). 15 amp six pole load break rated "segmenting" circuit breaker disconnect- allows connection of up to six low voltage PV subarrays which are then connected in series to form a high voltage PV array. Each subarray is 48 vdc nominal with an open circuit of less than 100 vdc maximum. Reduces the hazards of working with high voltage wiring during installation and troubleshooting Allows easy comparison of each PV subarray for verification of PV panel performance 3/4 and 1 inch conduit knockouts- one on the bottom and one on the back- with enough clearance provided to punch up to a 2 inch conduit for larger cabling for long wire runs. Eight 1/2 inch knockouts on bottom for PV module or subarray input conduits or strain reliefs. One 1/2 knockout on each side- with enough clearance provided to punch up to a 1-1/4 inch conduit for connecting multiple PSSB's together. One #1/0 AWG ground lug-can be located on inside or outside of enclosure-optional GBB for systems with multiple ground wires. Space allowed for the addition of current sensors and lightning protection components. Optional 15 amp 240 VAC disconnect breaker can be field installed inside the same enclosure to provide local means of disconnect at the inverter location. Ratings: 15 amps/600 vdc maximum Space is allowed for AC breaker or a second OBSB-15 segmenting breaker
