FAQ
Should I buy 4mm² or 6mm² cable diameter for my outdoor panel array? [Expand]
- Choose 4mm² lines for short micro-generation runs under 10 metres.
- Select heavy-duty 6mm² cable for high-amp runs or long paths.
- Thicker cross-sections reduce resistance losses across transmission tracks significantly.
Are the MC4 plugs listed above fully waterproof against heavy rain? [Expand]
- Yes, certified connectors carry strict IP67 or IP68 water protection ratings.
- Internal rubber compression seals block driving moisture and condensation risks.
- Ensure plugs snap together completely during installation to lock seals.
Why does standard domestic twin-and-earth wire fail on solar strings? [Expand]
- Standard household wire lacks cross-linked polyethylene weather protection tracking layers.
- Outdoor UV rays degrade standard domestic PVC insulation within months.
- Exposed wiring creates extreme fire hazards and system ground faults.
- Shield entry pathways safely by using matching Solar Surge Protectors.
