Introduction: When expanding your home solar system, is adding new solar panels complicated and requiring rewiring? Does your outdoor solar power station experience system shutdowns due to water ingress in connectors during heavy rain? In small-scale photovoltaic projects, are multiple panels connected in a messy parallel configuration, leading to significant power loss? Addressing these photovoltaic connection pain points, the new 10AWG 2-to-4 solar panel Y-splitter is now available. With tool-free quick installation, IP68 waterproof protection, and low-loss power transmission design, it becomes an efficient connection solution for home solar systems, outdoor energy storage, and small-scale photovoltaic power stations, easily handling multi-panel parallel connections and making solar power generation more stable and profitable!
Key Highlights
Adaptable to All Photovoltaic Scenarios:
✅ Flexible 2-to-4 splitting, cost-effective photovoltaic expansion: Using a standard Y-type parallel structure, it precisely matches mainstream MC4 photovoltaic connectors, enabling two core connection modes: “2 solar panels connected to 1 controller” or “1 power source split to 4 energy storage devices.” When expanding a home solar system from 3 panels to 5, there’s no need to replace the original controller and main cables; simply use the splitter for connection, reducing rewiring costs by 80%. When camping outdoors, it can simultaneously power solar panels, portable energy storage, and lighting equipment, offering flexible and versatile connection scenarios.
✅ 10AWG large wire diameter + tinned copper core, efficient and low-loss power transmission: Equipped with 10AWG thickened cables (wire diameter 2.588mm), it supports DC1000V high voltage and 30A rated current transmission, compatible with solar panels with a single panel power of up to 500W, and a total power capacity of up to 1500W when multiple panels are connected in parallel. The wire core uses 99.9% high-purity tinned copper, improving conductivity by 20% compared to ordinary copper cores, and controlling power transmission loss to within 1%—for example, in a 10kW photovoltaic system, it can reduce power loss by nearly 100 kWh per year, equivalent to an increase of 30 yuan in power generation revenue.
✅ IP68 Waterproof + All-Scenario Durability, Built to Last 10 Years Outdoors: The casing is made of high-temperature resistant PPO engineering plastic, certified to UL94V-0 flame retardant standards, self-extinguishing within 30 seconds in the presence of open flames; the connectors are equipped with double-layer silicone sealing rings, achieving IP68 waterproof and dustproof rating, and can be submerged in 1.5 meters of water for 60 minutes without water ingress. A wide operating temperature range of -40°F to 221°F (-40℃ to 105℃) makes it suitable for the harsh cold of Northeast China, the high temperatures of Hainan, and the strong ultraviolet radiation of high-altitude areas. It will not age or crack during long-term outdoor use, with a lifespan of 15 years or more, matching that of solar panels.
✅ Tool-Free Snap-On Connection, Easy for Beginners in 10 Minutes: Utilizing the MC4 standard snap-on design, the terminals have a built-in precision spring clip structure. No stripping, welding, or professional tools are required. Simply align with the solar panel interface and gently push until you hear a “click” sound for a secure connection. The insertion and extraction force is over 50N, ensuring it won’t loosen even with outdoor wind and vibration. Tests show that even beginners with no photovoltaic installation experience can connect two panels to the splitter by simply following the instructions, saving 70% of the installation time compared to traditional wiring methods.
Authoritative Certification, Guaranteed Quality: The entire product series has passed multiple international photovoltaic certifications, including UL, TUV, and IEC61215. Each batch of products undergoes 12 rigorous tests, including high-voltage breakdown, insertion/extraction life, and weather resistance. The terminals use gold plating technology, maintaining low contact resistance even after more to 500 insertions and extractions; the cable anti-aging test reaches 1000 hours, and the insulation layer does not become brittle under strong ultraviolet radiation. Suitable for home photovoltaic systems, outdoor power plants, and small commercial and industrial photovoltaic projects.
