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
