Victron SmartSolar 150V/45A MPPT Solar Charge Controller

The Victron SmartSolar 150V/45A MPPT solar charge controller has Bluetooth built in for wireless set-up and monitoring, and uses ultra-fast MPPT to get the most from your solar panels.

Features

• Built-in Bluetooth Smart to set up, monitor, update and synchronise the controller wirelessly
• Ultra-fast MPPT improves energy harvest by up to 30% compared to PWM controllers and up to 10% compared to slower MPPT controllers, especially under changing cloud
• Load output with automatic low-voltage disconnect helps prevent battery over-discharge; short-circuit proof
• Battery Life algorithm adjusts the load disconnect level so the battery is regularly recharged to nearly 100%
• VE.Direct port for a wired connection to a Color Control GX, other GX products, PC or other devices
• 12/24/48V battery voltage (auto-select); 45A rated charge current; 150V maximum PV open circuit voltage
• Peak efficiency 98%, no cooling fan; full output current up to 40°C
• Protected against PV reverse polarity, output short circuit and over-temperature
• Weighs 1.25kg; 130 × 186 × 70 mm

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.
