Victron Energy MC4-Y Solar Splitter Pair, 1x M-2F, 1x F-2M

Overview

The Victron Energy SCA520500000 is a Solar Splitter Pair MC4-Y for joining two MC4-equipped solar panels in parallel and feeding them back into a single positive and negative output pair.

The pair includes one male-to-two-female splitter and one female-to-two-male splitter, so both sides of a parallel solar connection can be completed cleanly. It is a practical fit for boat solar arrays where two panels need to share the same run to an MPPT solar charge controller, subject to the controller input limits and the combined current of the panels.

On board, this kind of MC4 Y-connector is most useful when adding a second panel to a cabin top, hardtop, arch, or deck-mounted solar setup without rebuilding the full PV cable path. Keep the connectors supported, protected from standing water, and routed so vibration or panel movement does not pull directly on the cable ends.

Key features

• MC4-Y splitter pair for connecting two solar panels in parallel.
• Includes both polarities: 1x male-to-2x female and 1x female-to-2x male.
• Creates one combined output pair from two panel inputs, helping keep the solar cable run tidy.
• Useful for marine solar layouts on hardtops, arches, deck mounts, and cabin-top panel installations.
• Works with MC4-style solar panel leads commonly used in photovoltaic systems.
• Simple inline installation with no programming, display setup, or network configuration required.

Installation and setup

Before fitting the splitters, confirm that the two panels are suitable to be paralleled and that the solar charge controller can accept the combined input current. The panels should be connected with matching polarity, and each MC4 connection should be fully seated so it locks into place.

For marine installations, route the cable run with drip loops where needed and secure the wiring so the splitters are not left hanging from the panel leads. Avoid sharp bends, chafe points, and locations where gear, sails, fishing tackle, or engine-room service work could pull on the connectors.

Compatibility and system integration

This splitter pair is for solar wiring that uses MC4 connectors. It does not convert voltage, regulate charging, add monitoring, or replace the need for a correctly sized MPPT or PWM solar charge controller.

It can be used in 12V, 24V, or higher battery-system installations only as part of the PV side of the system, where the solar panel and charge controller specifications support the array layout. The key check is not the battery voltage label, but the panel voltage, combined current, cable sizing, fusing plan, and solar controller input rating.

Use cases on board

This is a good match for boat owners adding a second panel to an existing MC4 solar run, tidying a small parallel array, or replacing a worn Y-connector pair in a compact marine solar installation.

It is especially useful on cruising boats, fishing boats, and workboats where solar panels are often split across limited deck or hardtop space but still need to feed a common charge controller input.

What’s included

• 1x MC4-Y splitter, male to 2 female connectors.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
