Frequently Asked Questions

AI
MC4 connectors are the industry standard for solar panel-to-panel or panel-to-inverter connections due to their waterproof sealing and high voltage rating. SAE connectors are typically used for lower-voltage battery connections or fuse holders in automotive and RV applications, offering quick disconnect capabilities.
Tinned copper is coated with a thin layer of tin, which provides superior resistance to corrosion and oxidation, especially in humid or marine environments. This ensures a longer lifespan and more consistent electrical conductivity compared to bare copper, which can degrade faster when exposed to moisture.
Wire gauge (AWG) depends on the current (amperage) and the distance the electricity must travel. Thicker wires (lower AWG numbers like 4 or 6) handle more current and reduce voltage drop over long distances. Always consult your inverter and panel specifications to ensure the cable can handle the maximum amperage safely.
