Bluetooth Smart built-in

The wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.

Ultra-fast Maximum Power Point Tracking (MPPT)

Especially in the case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30 % compared to PWM charge controllers and by up to 10 % compared to slower MPPT controllers.

Load output

Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage (48 V model: interface with a relay). Alternatively, an intelligent battery management algorithm can be chosen. The load output is short-circuit proof.

Battery Life: intelligent battery management

When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100 %. From that point onwards, the load disconnect level will be modulated so that a nearly 100 % recharge is achieved about once every week

What does a caravan solar system do?

A caravan solar system charges your battery using sunlight, helping power lights, fridges, and appliances when off-grid.

Do I need a solar controller?

Yes, a solar controller regulates voltage and protects your battery from overcharging.

What is the difference between MPPT and PWM controllers?

MPPT controllers are more efficient and better for larger systems, while PWM controllers are simpler and more affordable.

How many solar panels do I need for my caravan?

It depends on your power usage, but most setups use 100W–300W panels or portable blankets for flexibility.

What is a portable solar blanket?

It is a foldable solar panel system that can be moved and positioned in sunlight for flexible charging.

Can solar panels fully power a caravan?

They can support or fully power systems depending on battery size, usage, and panel capacity.

What is a battery management system (BMS)?

A BMS protects and balances your battery to ensure safe charging and longer lifespan.

Do I need lithium batteries for solar setups?

Not always, but lithium batteries are more efficient, lighter, and better suited for deep cycling.

Can I add more solar panels later?

Yes, most systems can be expanded if your controller and battery system allow it.

Are caravan solar systems hard to install?

Some components can be DIY installed, but full systems are often best installed by professionals.
