10 Pairs MC4 Solar Connectors 1000V 30A IP67 Waterproof UV
10 Pairs MC4 Solar Connectors – 1000V / 30A, IP67 Waterproof, UV-Resistant
Keep your solar panel system running at peak performance with this set of 10 Pairs MC4 Solar Connectors. Engineered for residential and commercial photovoltaic (PV) installations, these male and female connectors deliver a secure, low-resistance electrical connection rated up to 1000V and 30A — built to handle the demands of real-world solar arrays.
Key Features
- IP67 Waterproof Seal: An integrated waterproof ring forms a tight seal at each connection point, locking out moisture, dust, and debris to prevent corrosion and maintain long-term conductivity.
- High-Grade Copper Contacts: Solid copper contact pins provide excellent electrical conductivity and reliable current transfer across your PV cable runs.
- PPO Insulation Housing: The polyphenylene oxide (PPO) shell offers outstanding resistance to UV radiation, high temperatures, and harsh weather — no fading, cracking, or brittleness after years of outdoor exposure.
- Wide Cable Compatibility: Fits PV cables with insulation diameters from 2.5 mm² to 6 mm², making these connectors versatile across most standard solar cable gauges.
- All-Weather Durability: Designed to withstand heavy rain, strong winds, snow, and prolonged sun exposure — ideal for rooftop, ground-mount, and off-grid solar installations.
- Universal MC4 Standard: Compatible with most MC4-type solar panels, charge controllers, and inverters available on the market today.
- Value Pack: Includes 10 male + 10 female connectors (10 pairs total) — enough for a full small-to-mid-size solar array or to stock up as spares.

Frequently Asked Questions
Q: Are these MC4 solar connectors compatible with all solar panels?
A: Yes — these connectors follow the universal MC4 standard and are compatible with the vast majority of solar panels, charge controllers, and inverters that use MC4-type connections. They also accommodate PV cables with insulation diameters ranging from 2.5 mm² to 6 mm², covering most standard solar cable sizes.
Q: How waterproof are these MC4 connectors?
A: These connectors carry an IP67 waterproof rating, meaning they are fully protected against dust ingress and can withstand temporary immersion in water. An integrated waterproof ring seals the connection point to prevent moisture and corrosion — making them fully suited for permanent outdoor solar installations exposed to rain, snow, and humidity.
Q: What makes the PPO housing better than standard plastic?
A: PPO (Polyphenylene Oxide) is an engineering-grade polymer with superior resistance to UV radiation, high temperatures, and long-term environmental weathering compared to standard plastics. This means the connector housings won't become brittle, discolor, or degrade after years of direct sun exposure, ensuring a lasting, reliable installation.
Q: How many connectors are included in this pack?
A: This pack includes 10 pairs — that's 10 male connectors and 10 female connectors (20 connectors total) — providing enough connections for a small-to-medium solar array or a handy supply of spares for future maintenance and expansion.
