Victron Energy SCA500100000 Solar Adapter Cable L=15cm Fits MC4/M to MC3/F
Victron Energy SCA500100000 MC4 Male to MC3 Female. The Second Half of a Complete MC4/MC3 Adaptation.
Product Overview
The Victron Energy SCA500100000 is a 15cm solar adapter cable with an MC4 male connector on one end and an MC3 female connector on the other, designed to bridge the connection between modern MC4-terminated solar equipment and older MC3-terminated panels, charge controllers, or inverters. It is the polarity companion to the SCA500200000 (MC4 Female to MC3 Male) together, the two adapters provide a complete MC4-to-MC3 adaptation across both the positive and negative conductors of a solar DC circuit.
Purchased individually, the SCA500100000 adapts one conductor run typically the positive or negative, depending on your system's connector orientation. If both runs in your installation require MC4-to-MC3 adaptation, both this cable and the SCA500200000 are needed. At 15cm, this is a point-of-connection adapter, not an extension cable its role is to resolve a connector mismatch cleanly at the junction, not to add cable length to the circuit.
Key Specifications
- Part Number: SCA500100000
- Cable Type: Adapter — single connector conversion (not a splitter or extension)
- Connector End 1: MC4 Male
- Connector End 2: MC3 Female
- Cable Length: 15cm
- Quantity: 1 cable (single)
- Polarity Companion: SCA500200000 (MC4 Female to MC3 Male — sold separately)
- Construction: Weatherproof, outdoor-rated
- Maximum Voltage Rating: Not specified — confirm with supplier
- Maximum Current Rating: Not specified — confirm with supplier
- Cable Cross-Section: Not specified — confirm with supplier
- IP Rating: Not specified — confirm with supplier
Features & Benefits
- MC4 Male to MC3 Female Conversion — Resolves the connector incompatibility between modern MC4 male outputs and legacy MC3 female inputs. Enables integration of MC3-terminated equipment into MC4 solar systems without rewiring, replacing connectors, or sourcing custom cables.
- Polarity Companion to SCA500200000 — A solar DC circuit requires adaptation on both the positive and negative runs. The SCA500100000 (MC4/M to MC3/F) handles one polarity; the SCA500200000 (MC4/F to MC3/M) handles the other. Both are required for a complete two-conductor MC4-to-MC3 adaptation — confirm which combination your installation requires before ordering.
- 15cm Point-of-Connection Adapter — Designed to resolve a connector mismatch at the junction point — not to extend a cable run. The compact 15cm length minimises added resistance and voltage drop at the adapter and keeps the connection tidy within a combiner box, junction housing, or controller input bay.
- Single Cable — One Polarity — This product is a single cable adapting one connector. If both positive and negative runs require adaptation, two adapters are needed (this cable plus SCA500200000).
- Weatherproof Construction — Suitable for permanent outdoor installation, handling UV exposure, temperature cycling, and moisture in Australian rooftop, ground-mount, caravan, and marine solar environments.
- Tool-Free Connection — MC4 and MC3 connectors mate by hand without tools. An MC4 removal tool is required for safe disconnection of the MC4 end — do not disconnect under load.

Compatible With / Goes Well With
Typical Use Cases:
- Connecting MC4 male solar panel or cable outputs to legacy MC3 female controller or inverter inputs
- Integrating older MC3-terminated equipment into modern MC4 solar systems
- Completing a full two-conductor MC4-to-MC3 adaptation alongside SCA500200000
Compatible Equipment:
- Any solar panel, cable, or device with a standard MC4 male output
- Any solar charge controller, inverter, or device with an MC3 female input
Commonly Paired With:
- SCA500200000 — Victron MC4 Female to MC3 Male adapter (opposite polarity — for complete two-conductor adaptation)
- Victron SmartSolar or BlueSolar MPPT charge controllers
- MC4 solar extension cables and Y-splitter branch connectors
Frequently Asked Questions
What is the difference between this cable and the SCA500200000?
The SCA500100000 has an MC4 male connector and an MC3 female connector. The SCA500200000 has an MC4 female connector and an MC3 male connector. Both are needed to adapt a complete two-conductor solar DC circuit from MC4 to MC3 — one for each polarity run.
Do I need this cable, the SCA500200000, or both?
It depends on your installation. A solar DC circuit has two conductors. If both require adaptation between MC4 and MC3, you need both cables. If only one run has a connector mismatch, one cable may suffice. Confirm the connector orientation at each end of your positive and negative runs before ordering.
What is the difference between MC3 and MC4 connectors?
MC3 is an earlier solar connector standard found on older panels, inverters, and charge controllers. MC4 is the current industry standard with an improved locking mechanism and wider compatibility. The two formats are not directly compatible — this adapter bridges the two at the point of connection without rewiring.
Can I use this as an extension cable between my panel and charge controller?
No. At 15cm, this is a point-of-connection adapter designed to resolve a connector mismatch — not to add cable length. For extending runs between panels and controllers, MC4 solar extension cables of the appropriate length and cross-section are required.
Is this cable suitable for permanent outdoor installation?
Yes — the weatherproof construction is designed for outdoor use. Maximum voltage, current, and IP ratings are not confirmed in the available product data; verify these from the Victron datasheet against your system specifications before permanent installation.
