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.
