The CT4503 is a set of interconnecting, MC4 to 4 mm sheathed banana plug leads. Designed to allow the measurement of open-circuit voltage (Voc) and short-circuit current (Isc) of solar panels, they provide a reliable and safe connection between photovoltaic modules and your measuring device. The double insulated PVC wire is both flexible and durable to provide ease of use. These photovoltaic leads can be used with Cal Test’s CT4491, MC4 extension lead, whenever additional lead length is required.

Available individually, as a pair, or in a kit.
