Victron Energy SCA500200000 Solar Adapter Cable L=15cm Fits MC4/F to MC3/M
Victron Energy SCA500200000 Bridge MC4 and MC3 Solar Connectors in 15cm.
Product Overview
The Victron Energy SCA500200000 is a 15cm solar adapter cable with an MC4 female connector on one end and an MC3 male connector on the other, designed to bridge the connection between MC4-equipped solar panels or charge controllers and older MC3-terminated equipment. MC3 is an earlier-generation solar connector standard that pre-dates MC4 while MC4 has become the universal standard in modern solar installations, MC3 connectors are still found on legacy panels, inverters, and charge controllers that would otherwise be incompatible with current MC4 wiring.
At 15cm, this is an adapter rather than an extension cable its purpose is to resolve a connector mismatch at the point of connection, not to add cable run length. The compact format minimises added resistance in the connection and keeps the adaptation point tidy within a combiner box, junction, or controller input. It is sold as a single cable adapting one connector pair if both positive and negative runs require adaptation, two cables are needed.
Key Specifications
- Part Number: SCA500200000
- Cable Type: Adapter — single connector conversion (not a splitter or extension)
- Connector End 1: MC4 Female
- Connector End 2: MC3 Male
- Cable Length: 15cm
- Quantity: 1 cable (single)
- 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 Female to MC3 Male Conversion — Resolves the connector incompatibility between modern MC4-terminated solar panels, cables, and equipment and legacy MC3-terminated devices. Enables continued use of MC3-equipped inverters, charge controllers, or panels alongside modern MC4 components without rewiring or replacing connectors.
- 15cm Compact Adapter Length — At 15cm, this cable is designed to bridge a connector mismatch at the point of connection — not to extend a cable run. The short length minimises added resistance and voltage drop at the adapter junction, and keeps the installation tidy within a combiner box, junction housing, or controller input bay.
- Single Cable — Covers One Polarity — This is a single adapter cable. A solar DC circuit has two conductors — positive and negative — each requiring an adapter if both ends use mismatched connectors. If both runs need MC4-to-MC3 adaptation, two cables are required. Confirm whether positive and negative runs both require adaptation before ordering.
- Weatherproof Construction — Built for permanent outdoor installation, handling the UV exposure, temperature cycling, and moisture found in Australian rooftop, ground-mount, caravan, and marine solar installations.
- Plug-and-Play Installation — MC4 and MC3 connectors are tool-free to connect by hand. No crimping or stripping required for the connection itself — simply mate the connectors and click into place.

Compatible Equipment:
- Any solar panel or device with a standard MC4 female output (panel side)
- Any solar charge controller, inverter, or device with an MC3 male input
Commonly Paired With:
- Victron SmartSolar or BlueSolar MPPT charge controllers

Frequently Asked Questions
What is the difference between MC3 and MC4 solar connectors?
MC4 is the current industry-standard solar connector, introduced as an improvement over the older MC3 format. MC3 connectors are a single-contact design found on older solar panels, charge controllers, and inverters. MC4 uses a more secure locking mechanism and is not directly compatible with MC3 — this adapter bridges the two at the connection point.
Do I need one cable or two for my installation?
A solar DC circuit has two conductors — positive and negative. If both runs require adaptation from MC4 to MC3, you will need two adapter cables. If only one run requires adaptation (e.g. your equipment uses MC4 on one terminal and a bare wire on the other), one cable may be sufficient. Confirm your specific installation requirements before ordering.
Can I use this cable as an extension lead between solar panels and my charge controller?
No. At 15cm, this cable is an adapter — not an extension. It is designed to resolve a connector mismatch at a single connection point. For extending cable runs between panels and controllers, MC4 solar extension cables of the appropriate length and cross-section are required.
Will this adapter work with any brand of MC4 and MC3 connectors?
It is compatible with standard MC4 female and MC3 male connectors. Some proprietary or non-standard connector variants may not mate correctly — confirm your equipment uses standard MC3 and MC4 connector formats before purchase.
Is this adapter suitable for permanent outdoor installation?
Yes. The weatherproof construction is designed for outdoor use. However, maximum voltage, current, and IP ratings are not confirmed in the available product data — confirm these from the Victron datasheet against your system specifications before permanent installation.
