Victron Energy Solar Adapter Cables (MC4 to MC3)
Free shipping over $49
60-day hassle-free returns
Short adapter leads that bridge the MC4 and older MC3 connector standards. If you're connecting newer MC4-equipped panels, cables, or charge controllers to legacy MC3 wiring (or vice versa), these 15 cm adapter cables make a clean, weatherproof transition without re-terminating anything.
- Two versions: MC4 male to MC3 female and MC4 female to MC3 male - choose the one that matches the ends you need to join.
- 15 cm (6 in) tinned-copper PV lead with factory-fitted connectors.
- UV-resistant, double-insulated jacket rated for outdoor and marine exposure.
- IP68, water-tight connections with a secure locking fit.
- Order both versions to adapt an in-line MC3-to-MC4 splice in either direction.
Pairs with: Victron MC4 solar cables and SmartSolar and BlueSolar MPPT charge controllers.
