One pair gives you the MFF (male to two females) and FMM (female to two males) so you can double your current without any custom crimping or adapters. IP67 waterproof, thick copper tinned pins, and sturdy housing—they feel like they’ll outlast the panels themselves. Pros: • Plug-and-play perfection — Compatible with standard MC4 panels (Renogy, HQST, BougeRV, etc.); locks click solidly with zero wiggle • Real waterproofing — Fully sealed, survived heavy Arkansas rain and hose-downs with no issues • Heavy-duty build — Thick insulation and UV-resistant plastic; no melting or cracking after months in direct sun • Increases output exactly as expected — Doubled my 200W panels’ amperage cleanly, no voltage drop or heat buildup • Great value — Half the price of name-brand MC4 Y connectors but performs identically Cons: • Only one pair per pack — If you’re wiring more than two panels in parallel, you’ll need multiple sets (but that’s obvious) • Locks are tight — Takes a firm pull with the included tool to disconnect (good for security, annoying if you reconfigure often) • No fancy extras — Just the connectors, no storage bag (minor nitpick) If you’re expanding your RV, cabin, or off-grid solar array and need clean parallel connections, these BougeRV Y branch connectors are a no-brainer. Simple, reliable, and tough—exactly what you want in solar hardware. 5 stars, highly recommend! Review: Good quality - Initail testing is good, fits perfectly on my cables; appear to be good quality heavy duty pieces. Fast shipping too. ## Features - SOLAR Y BRANCH CONNECTORS: 1 male to 2 female(M/FF) and 1 female to 2 male(F/MM), it is compatible with solar cables or connectors in 14AWG to 10AWG, it could be used for paralleling solar panels - WATERPROOF AND DURABLE: An IP67 waterproof ring on the male connector seals out water and dust to prevent corrosion. The connector features a built-in lock for a secure hold, and it withstands outdoor conditions - HIGH SECURITY: The connectors are made with PPO material and tinned copper, ensuring stable performance in temperatures ranging from -40°F to +230°F - EASY INSTALL: Plug and play.

Then you would need a negative and positive homerun lead to connect these to a combiner box or whatever **Q: Are these the equivalent of AVG 8 or 10 or 12?** A: See this chart: https://www.bluesea.com/resources/1437 For critical circuits (like power systems that require less than 3% voltage drop), using the largest indicated wire size (6mm^2 or 10GA) would restrict 12V applications to round-trip circuits of 60ft @ 5A (60W), 30ft @ 10A (120W), and no more than 20ft @ 15A (180W). "Round-trip" means adding up the lengths of both the positive and the negative feeds - so the actual length of 10GA duplex wire to handle a single solar panel feed of 175 watts would be no more than 10ft. If one additional solar panel is added in parallel, the circuit must now be able to handle 350 watts, or 30A (per P = V * I). While 10GA wire is capable of handling this load, the 3% voltage loss rule now reduces the maximum distance between panels and load to 5ft. Even if the wire is able to handle the amps, the voltage drop specification is equally important, especially in this case. Solar panels typically feed into multi-stage battery charging systems, which can be extremely sensitive to minor differences in voltage levels (that's how the charger knows how much power to send to the battery). Excessive voltage drops due to insufficiently sized wiring can make the difference between healthy batteries that are fully charged and maintained at a float level of 14.4V, and ruined batteries that were overcharged because the charger couldn't get above 14.0V. The 3% voltage drop value represents this precise difference (between 14.4V and 14.0V). **Q: Do these connectors have a "max amp" rating?** A: Hi customer, the max amp (Rated current) of these connectors is UL 25A or TUV 30A, the rated voltage of these connectors is UL 600V DC or TUV 1000V DC Maximum. Which standard you choose is according to your location or your habit, usually, people in US choose the UL as the standard, people in Europe choose TUV as the standard. **Q: What connects do i need to add 2(two) 300w/24v panels in series ?** A: This solar branch is made for connecting panels in parallel. Most batteries have PWM charge controllers, which can use only parallel connections. If you have a battery with an MPPT charge controller, you can hook up either way, parallel or in series. For series, you probably won't need an adaptor, as long as your panels have the normal male/female connectors and you have an extension cord with the same connectors that go to your battery. They recommend though, that you have some fuses in between along the way, in connecting the red or positive cables, if you are hooking in series. For series you connect your two panels together with one male and female. The other male and female from each will go to the charge controller or battery. I would Google the connections before actually doing it. But for series, you don't need the solar branch connectors. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dead-Simple Parallel Wiring That Just Works *by J***C on 8 February 2026* These BougeRV Y connectors are the no-drama way to hook two solar panels in parallel.
