40A MPPT Charge Controller | 12/24V

£95.00 Inc. VAT

Our 40A MPPT controller ensures that 99% of the available energy is extracted from the panels and stored. Even in partly overcast conditions with constantly changing light intensity, this controller maximizes energy yield.

With multiple in-built battery safety features that protect & extend the life of your battery, you can trust this controller with your off-grid setup.

  • Suitable for 12/24V systems up to 520/1040 watts.
  • Dimension: 196*136*67mm | 1.3kg

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.
