This solar extension cable is perfect for connecting solar arrays & charge controllers or multiple solar panels together. 6 metres of cable provides you with plenty of freedom in the placement of your components.
✓MC4 connectors for easy installation
✓Pure tinned copper for greater conductivity
✓IP67 waterproof and weatherproof
Recommended for Voltanic’s small panels. For the larger 400w panels we recommend that you use 6mm² cabling.
12V solar panels actually output around 20V
12V leisure batteries charge at just over 12V*
Standard PWM controllers simply drop those extra 8V — throwing away precious power
Every Voltanic Kit takes those wasted volts and converts them into extra amps using Advanced MPPT (Maximum Power Point Tracking) Technology.
Harvest 100% of your Solar Energy - No wasted watts
Charge your Batteries 30% Faster
More Power, Fewer Panels - Perfect for tight spaces
Better Value Investment - Get what you pay for
| Controller | Standard PWM | Voltanic MPPT |
|---|---|---|
| Panel Voltage | 20V | 20V |
| Controller Charging Voltage | 12V (PWM reduces voltage) |
12V (MPPT reduces voltage) |
| Amperage | 5.8A (amps stays same) |
8.2A (MPPT increases amps) |
| Power Output | 12V × 5.8A = 70W | 12V × 8.2A = 98W |
| Power Wastage | ~30W (lost as heat) |
~2W (conversion loss) |
