Most solar kits have a dirty little secret they don’t tell you about: they waste valuable power.

Here’s the deal

112V solar panels actually output around 20V
212V leisure batteries charge at just over 12V
3Standard 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.

Standard PWMDrops the extra 8V. Amps stay the same.
