This higher system voltage is a significant advantage for larger arrays, as it means more PV panel modules can be connected in series within a string. The number of strings in an array can therefore be reduced, with a consequent reduction in the number of components required, such as couplings, overcurrent safety switch systems, contact breakers and cables. Combined with the fact that inverters are cheaper in this voltage range, installation costs can be as much as 30% lower.
The connectors can be supplied preassembled or they can be attached to cables on site using crimping pliers. Cables up to 10 mm2 in cross-section can be accepted, making them suitable for currents as high as 43A.
