Most solar kits have a dirty little secret they don't tell you about:
They waste valuable power.
Here's the deal
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
In cloudy Britain where every watt counts, this is a problem.
The Voltanic Difference
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
Maximum Power. Zero Waste.
Real World Comparison:
100W Panel Performance
Watts = Volts x Amps
| 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) |
