DUAL BATTERY CHARGING

Power up both your main battery and your auxiliary/starter battery. Stay safe on road trips with plenty of charging options.

WIDE SAFETY PROTECTION

Advanced protection for battery charge and discharge, plus overheating, PV reverse polarity, and more.

COMPATIBLE WITH ALL BATTERIES

Supports all battery types for endless possibilities. AGM / Lead Acid / LiFePO4 / GEL / SLD / FLD

MORE WAYS TO CHARGE

This mode will charge your leisure battery from both power sources—whether at the same time or choosing one—the solar panels and the engine. It works with both smart alternators and regular ones.

Charge your starter battery from both solar panels and your leisure battery when the sun is bright and the starter battery voltage drops below the set level.

With the same energy sources—your alternator (engine) and solar panels—you can choose to charge two batteries: your main leisure battery and a second one for emergencies or backup.

This is the simplest setup, charging your leisure battery from solar panels. If this mode is all you need, click here to explore our standard MPPT controllers—more suitable and affordable for this purpose.

SQUEEZE EVERY DROP OF POWER

To charge your batteries from solar panels, the MPPT (Maximum Power Point Tracking) technology in this device lets you harvest 99% of the available energy—up to 30% more than PWM (standard) controllers.

CHARGE BETWEEN 12V AND 24V

With back boost charging technology, you can charge between a 12V and a 24V battery.

SMART DESIGN. EASY FIT.

LOW PROFILE

Voltanics panels offer a sleek design; frame, backsheet, and edge busbars all matched for a clean, uniform look that blends in.

EASY TO INSTALL

Pre-drilled mounting holes to fit a variety of mounting systems, plus corner 90cm cable with MC4 for easy wiring.

LATEST N-TYPE TOPCON TECHNOLOGY

Voltanic rigid panels are designed with the latest TOPCon N-Type technology to give you more power from the same sunlight.

MORE POWER IN LESS SPACE

Thanks to advanced N-Type TOPCon cells, Voltanic panels produce the same power in less space, making them compact and over 10% shorter, the perfect size for fitting solar panels into your campervan or motorhome.

WORRY-FREE SET-UP

Don’t worry about wiring, we include all the cables you need, with up to 6 metres in length so you can reach anywhere required. The correct gauge and fuse are included to keep everything safe.

We use insulated, TÜV-approved cables to ensure minimal voltage drop.

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.
24V 20V 16V 12V 8V 20V Input 12V Output 8V Wasted as Heat
24V 20V 16V 12V 8V 20V Input 12V Output Converting to Extra Amps
