Frequently Asked Questions
Can I use a solar extension cable to power lights under my shade sail?
Yes. Use a weatherproof outdoor-rated cable (10AWG for longer runs or higher current) with sealed connectors (IP67 or similar) and confirm polarity and connector compatibility with your lights or solar controller before connecting.
What does IP67 mean and do I need it for patio installations?
IP67 indicates the connector is dust-tight and can survive immersion in water up to 1 meter for a short time. For patio or garden use where connectors may be exposed to rain or spray, IP67-rated connectors provide much better protection than basic, unsealed plugs.
How do I avoid corrosion on connectors and turnbuckles?
Use tinned or tinned-coated conductors and choose stainless-steel or properly coated turnbuckles. Keep connections off the ground, use waterproof covers, apply dielectric grease on metal connections if appropriate, and inspect periodically for wear or loose fittings.
